+
+	Added functions to be used for fitting in
+	the "Fixierungsanalyse" and "Extremwertermittlung".
+
+	* src/main/java/de/intevation/flys/artifacts/math/fitting/Function.java: New.
+	  Abstract base class for functions to fit. Provides the name of the function,
+	  a short description, the names of the parameters and an initial parameter guess
+	  for the fit processe. Sub classes have to overwite the function evaluation and
+	  the partial derivative of the function in respect to the parameters.
+
+	  TODO: Add a meachnism for the inverse function (needed for AT export) and
+	  the first derivative (needed for the respective diagram).
+
+	* src/main/java/de/intevation/flys/artifacts/math/fitting/FunctionFactory.java:
+	  New. Factory to fetch a function by its name.
+
+	 * src/main/java/de/intevation/flys/artifacts/math/fitting/Exp.java: New.
+	   exp: W(Q) = m * a^Q + b
+
+	 * src/main/java/de/intevation/flys/artifacts/math/fitting/Quad.java: New.
+	   quad: W(Q) = n*Q^2 + m*Q + b

+	   pow: W(Q) = a*Q^c + d
+
+	   !!! This power function is new in the pool of functions to be fit. !!!
+	   See my mail "Manuelle Punkte in der Fixierungsanalyse" 2011-10-27 for details.
+	   The function exp-new found in the old FLYS function pool is omitted
+	   because it is worthless and was maybe never used.
+
+	* src/main/java/de/intevation/flys/artifacts/math/fitting/App.java: New.
+	  Small test driver to check if the fitting is working. The points to
+	  fit are read from stdin the function to fit is determined by the
+	  system property 'function'. Example usage:
+
+	    $ mvn -e \
+	    -Dfunction=linear \
+	    -Dexec.mainClass=de.intevation.flys.artifacts.math.fitting.App exec:java <<EOF

+
+	 * src/main/java/de/intevation/flys/artifacts/model/FixingsOverview.java:
+	   - Calculate the extent of the river by the extents of the fixings.
+	   Reason: The river Elbe has only has fixings up to km 351. The other half
+	   of the river is empty which results in a sparse looking overview.
+	   - Add the name of the river as name attribute to resulting <river> element.
+
+	 * contrib/fixoverview2html.xsl: New. Demo XSL transformation to turn
+	   the output of the overview service directly into HTML. Used in the
+	   client a variant of this script could be used for producing the content
+	   of the assistance widget. Usage:
+
+	   $ curl http://localhost:8181/service/fixings-overview \

+
+	* src/main/java/de/intevation/flys/artifacts/services/FixingsOverviewService.java:
+	  Made the filter mechanisms available via the incoming XML document.
+
+	  1 - range: Simply add a <range from="..." to="..."/> element next to the
+	      <river> element. Optional. Defaults to full extent.
+
+	  2 - filters: Add a <filter> element next to the <river> element.
+	      Optional. Defaults to accepting all.
+	      The <filter> element can contain the following elements:
+
+	        <column cid="..."/>: Creates an IdFilter.
+	        <date when="..."/>: Creates a DateFilter.
+	        <date-range from="..." to="..."/>: Creates a DateRangeFilter.
+	        <sector-range from="..." to="..."/>: Create a SectorRangeFilter.
+	        <not>...</not>: Creates a NotFilter. The nested element is negated.
+	        <and>...</and>: Create an AndFilter: The nested elements are 'and'ed.
+	        <or>...</or>: Create an OrFilter: The nested elements are 'or'ed.
+
+	  These filters need testing!
+
+	* src/main/java/de/intevation/flys/artifacts/model/FixingsOverview.java:
+	  Made date format a public constant.
+
+2012-02-20  Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/FixingsOverview.java:
+	  Added a filter mechanism for generating output.
+
+	  There are two kinds of filters:
+
+	  1 - A range. Defaults to [-Double.MAX_VALUE, Double.MAX_VALUE]
+	      The resulting sectors are cut to this range. Sectors outside
+	      this range are omitted.
+
+	  2 - column filters: Given a fixing column they can decide to keep
+	      or not to keep it. Following filters exist:
+
+	      - IdFilter: Keep column if column id matches.
+	      - DateFilter: Keep column if column date matches.
+	      - DateRangeFilter: Keep column if column date is in range.
+	      - SectorRangeFilter: Keep colum if one of its q sectors is in given range.
+	      - NotFilter: Negates another nested filter.
+	      - AndFilter: Keep column if all nested filters accept column.
+	      - OrFilter: Keep column if at least one of the nested filters accepts it.
+
+2012-02-20  Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/FixingsOverview.java:
+	  Refactored to build the Q sectors once at construction time and not

+	  This will ease the job of applying filters to the Overview.
+
+2012-02-19  Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	  Service to generate the data needed to build the "Fixerungen pro Fluss Uebersicht"
+
+	* src/main/java/de/intevation/flys/artifacts/services/FixingsOverviewService.java:
+	  New. A service that serves an XML overview version of the fixings of a given river.
+
+	  The input documents look like this:
+
+	    <?xml version="1.0" encoding="UTF-8"?>
+	    <fixings>
+	      <river name="Saar"/>
+	    </fixings>
+
+	  The output documents looks like this:

+	      </event>
+	      ...
+	    </events>
+	  </fixings>
+
+	  The <river> element contains the extent of the whole river
+	  and its db id.
+	  The <events> sections contains serveral <event> elements.
+	  They have a meassure date, db id, a name and a number of <sector>s.
+	  These sectors are q classified from/to ranges. Classes are:
+
+	  0: smaller (MNQ+MQ)/2
+	  1: (MNQ+MQ)/2 to (MQ+MHQ)/2
+	  2: (MQ+MHQ)/2 to HQ5
+	  3: greater HQ5
+
+	* src/main/java/de/intevation/flys/artifacts/model/FixingsOverview.java:

+
+2012-02-17  Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java(getMinMaxQ):
+	  Symmetrical to getMinMaxW() add two methods to find min/max Q for a given
+	  km or a range. The range method is maybe a bit slow.
+
+2012-02-17  Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+

+
+2012-02-16  Raimund Renkert <raimund.renkert@intevation.de>
+
+	Refactored the wq data fields.

+2012-02-14  Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	Another partial fix for flys/issue499: Do the W to Q conversions
+	needed for "W am Pegel" correctly.
+
+	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
+	  Repaired getQsForW(): The mapping from W to Q is not unique! There

+
+	* src/main/java/de/intevation/flys/artifacts/model/WW.java:
+	  Removed the createNormalized() method because it did not
+	  solve all problems with the transformation of the W~W data we have.
+
+	  - We need to shift the values to be based in (0, 0).
+	  - We need to linear transform the values if they are at gauges.
+	  - Copying the data is memory expensive.
+
+	  Therefore there is now a new inner class ApplyFunctionIterator
+	  that is able to transform the values in an iterator like manner.
+	  The transform functions default to the identity.
+
+	* src/main/java/de/intevation/flys/artifacts/math/Sub.java: New.
+	  Simple function that subtract a scalar from the parameter.
+

+
+	  Use improved caching for cross section data.
+	  !!! This commit needs heavy testing !!!
+
+	* src/main/java/de/intevation/flys/artifacts/services/CrossSectionKMService.java:
+	  Refactored to provide the map to determine the nearest cross section line
+	  neighbors for a given km to the public. This is a bit hackish because
+	  it hhould have its own factory which is then used by this service and
+	  other parts of the code.
+
+	* src/main/java/de/intevation/flys/artifacts/CrossSectionArtifact.java:
+	  searchCrossSectionLine() now returns a FastCrossSectionLine. To find this
+	  line efficiently it uses the map of the CrossSectionKMService which
+	  already provides a nearest neighbor searching mechanism for cross
+	  section lines. The FastCrossSectionLine is fetched with the
+	  FastCrossSectionLineFactory which uses a cache as described in the
+	  previous commit.

+
+	* src/main/java/de/intevation/flys/artifacts/model/FastCrossSectionLine.java:
+	  Added method fetchCrossSectionProfile() to access the point data in
+	  the profile generating compatible way.
+
+	* src/main/java/de/intevation/flys/artifacts/ChartArtifact.java: Removed
+	  superfluous import.
+
+2012-01-16	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* doc/conf/cache.xml: Added cache for fast section lines chunks.
+
+	* src/main/java/de/intevation/flys/artifacts/model/FastCrossSectionChunk.java:
+	  New. Chunks of FastCrossSectionLines. Stores cross section lines for ranges
+	  of one KM.
+
+	* src/main/java/de/intevation/flys/artifacts/model/FastCrossSectionLineFactory.java:
+	  New. Access fast cross section lines. It uses the cache 'fast-cross-section-lines'
+	  configured in cache.xml to store chunks of cross section lines.
+
+	* src/main/java/de/intevation/flys/artifacts/model/FastCrossSectionLine.java:
+	  New. Stores the important data (points) of a cross section line.

+
+2011-12-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java:

+
+2011-12-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/exports/AxisSection.java: Added method

+
+	* src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java:
+	  Modified createYAxis(int): call super.createYAxis(int) and adjust

+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: Added
+	  getXAxisLabelFontSize() and getYAxisLabelFontSize(int) to retrieve the

+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: Implement

+	  label.
+
+2011-12-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/exports/ChartSettings.java: Modified the

+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: Implements

+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java:
+	  Implemented the methods getChartTitle() and getChartSubtitle(). Both

+	  Renamed getChartTitle() and getChartSubtitle() to
+	  getDefaultChartTitle() and getDefaultChartSubtitle(). In addition, the
+	  methods addSubtitles() became more robust - these OutGenerators add
+	  subtitles only if the subtitle is not empty.
+
+2011-12-23  Ingo Weinzierl <ingo@intevation.de>

+
+2011-12-16  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:

+	  method to clear the list of Facets of a specific Output.
+
+	* src/main/java/de/intevation/flys/collections/AttributeWriter.java: The
+	  AttributeWriter no longer creates new CollectionAttributes - it only
+	  modifies the old CollectionAttribute. At first, it clears the Facets of
+	  all Outputs. Finally, the merged Facets are added to the Outputs.
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Added the CollectionAttribute to the AttributeWriters constructor.

+	  to set the axis label and id.
+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: Improved

+	  buildAxisSections() method in this class is not implemented and needs to
+	  be implemented by subclasses.
+
+	* src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java:
+	  Override buildAxisSections() of XYChartGenerator to create an AxisSection
+	  for each axis that is able to be displayed in this sort of chart. In

+	  for a specific Y axis.
+
+2011-12-15  Ingo Weinzierl <ingo@intevation.de>

+	  visible or not. In addition, the ChartSettings returned by this instance
+	  will now contain a LegendSection as well.
+
+2011-12-15  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: Introduced
+	  methods getChartSubtitle() and isGridVisible(). getChartSubtitle() returns
+	  in this implementation null. Concrete subclasses should override this
+	  mehtod if they require subtitles in charts. isGridVisible() determines if
+	  the grid in the chart should be visible or not. This method return always
+	  true in this implementation.
+	  In addition, the Settings object returned by getSettings() will now have a
+	  ChartSection set properly.

+
+	* src/main/java/de/intevation/flys/exports/EmptySettings.java: An
+	  implementation of the Settings interface defined in the artifact-database
+	  module. This implementation accepts no Section objects at all and creates
+	  an empty "settings" Node in its toXML() operation.
+
+	* src/main/java/de/intevation/flys/exports/OutGenerator.java: Defined a new
+	  method getSettings() that returns a Settings instance.
+
+	* src/main/java/de/intevation/flys/exports/ChartGenerator.java,
+	  src/main/java/de/intevation/flys/exports/ReportGenerator.java,
+	  src/main/java/de/intevation/flys/exports/MapGenerator.java,
+	  src/main/java/de/intevation/flys/exports/AbstractExporter.java,
+	  src/main/java/de/intevation/flys/exports/ATExporter.java,
+	  src/main/java/de/intevation/flys/exports/ChartInfoGenerator.java:
+	  Implemented the getSettings() operation. All OutGenerators will currently
+	  return an instance of EmptySettings.
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Before the DESCRIBE document is created, we gonna evaluate each Output
+	  defined in the Collection's attribute document, if it has a Settings
+	  object set. If this is not the case, the relevant OutGenerator is called
+	  to retrieve a new instance of Settings.
+
+	* src/main/java/de/intevation/flys/collections/CollectionAttribute.java:
+	  Append the Settings of Outputs to the Output nodes in the XML
+	  representation.
+
+2011-12-13	Felix Wolfsteller	<felix.wolfsteller@intevation.de>
+
+	Recommend cross-sections.
+
+	* doc/conf/meta-data.xml: When having a cross-section out, recommend
+	  respective artifacts.
+
+2011-12-13	Felix Wolfsteller	<felix.wolfsteller@intevation.de>
+
+	Register factory for CrossSectionArtifacts.
+
+	* doc/conf/conf.xml: Register CrossSectionArtifact-Factory.
+
+2011-12-13  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/collections/CollectionAttribute.java:
+	  New. This class will store the information provided in the Collection's
+	  attribute (which is a DOM document).
+
+	* src/main/java/de/intevation/flys/collections/CollectionDescriptionHelper.java:
+	  Store an instance of CollectionAttribute and append its XML representation
+	  to the DESCRIBE document.
+
+	* src/main/java/de/intevation/flys/collections/AttributeWriter.java: Removed
+	  all DOM operations from this writer. Its new task is to create a new
+	  CollectionAttribute object which represents a merged version of the old
+	  CollectionAttribute and the information provided by the Collection's child
+	  Artifacts.
+
+	* src/main/java/de/intevation/flys/collections/AttributeParser.java: The
+	  result of AttributeParser's parse() operation is a CollectionAttribute
+	  object now. The methods getOuts() and getFacets() are as of now proxy
+	  methods that call the relevant methods of CollectionAttribute.
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Some structural changes in the process to build the attribute Document of
+	  the Collection's DESCRIBE. We will no longer work with Document during
+	  this process but with instances of CollectionAttribute.
+
+2011-12-13	Felix Wolfsteller	<felix.wolfsteller@intevation.de>
+
+	Server-side of newer Cross-Section diagram construction architecture.
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java
+	  (searchCrossSectionKmLine, getCrossSectionSnapKm),
+	  (getCrossSectionData): Removed, most functionality contained in
+				 CrossSectionArtifact.
+	  (getWaterLines): Now get CrossSectionLines to calculate water line.
+
+	* src/main/java/de/intevation/flys/artifacts/model/CrossSectionWaterLineFacet.java:
+	  Get a CrossSectionLine from blackboard.
+
+	* src/main/java/de/intevation/flys/exports/CrossSectionGenerator.java:
+	  Hard TODO, commented out function needed for subtitle to allow
+	  compilation.
+
+	* src/main/java/de/intevation/flys/exports/StyledSeriesBuilder.java:
+	  Added Empty-Dataset- guard.
+
+2011-12-13	Felix Wolfsteller	<felix.wolfsteller@intevation.de>

+
+2011-12-13  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/collections/CollectionDescriptionHelper.java:
+	  New. This class helps generating the DESCRIBE document of a collection.
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Moved some of the code to create the DESCRIBE document out to
+	  CollectionDescriptionHelper.
+
+2011-12-12	Felix Wolfsteller	<felix.wolfsteller@intevation.de>
+
+	Resolve todo about wrongly named cross sections.
+	Open StaticState to allow that facets survive a compute.
+
+	* src/main/java/de/intevation/flys/artifacts/states/StaticState.java
+	  (computeAdvance, computeFeed, computeInit): Override to call
+						      staticCompute.
+	  (staticCompute): New. Do nothing but be able to be overridden.
+
+	* src/main/java/de/intevation/flys/artifacts/CrossSectionArtifact.java
+	  (setup): Fetch facets name from db (resolves todo).
+	  (getCurrentState): override staticstates staticcompute to let

+
+2011-12-12  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/wsplgen/JobExecutor.java,
+	  src/main/java/de/intevation/flys/wsplgen/WSPLGENCallable.java: Renamed
+	  JobExecutor to WSPLGENCallable (because it is a Callable now). In addition
+	  to the call() method which starts the WSPLGEN process, this Callable
+	  offers a cancelWSPLGEN() method to destroy a running WSPLGEN process.
+
+	* src/main/java/de/intevation/flys/wsplgen/WSPLGENFuture.java: A FutureTask
+	  that overrides cancel(boolean). Before this instance call
+	  super.cancel(boolean), it executes WSPLGENCallable.cancelWSPLGEN() to kill
+	  a running WSPLGEN process.
+
+	* src/main/java/de/intevation/flys/wsplgen/Scheduler.java: The Scheduler is
+	  no longer a Runnable. It makes now use of a ScheduledThreadPoolExecutor to
+	  schedule the incoming WSPLGENJobs. The ScheduledThreadPoolExecutor has a
+	  fixed number of worker threads that process the jobs. The number is 1 per
+	  default; it can be modified using a System property "wsplgen.max.threads".
+
+	* src/main/java/de/intevation/flys/artifacts/context/FLYSContext.java: Added
+	  a string constant SCHEDULER.
+
+	* src/main/java/de/intevation/flys/wsplgen/SchedulerSetup.java: A
+	  LifetimeListener that currently implements the systemUp() method to create
+	  an instance of Scheduler. After its creation, the Scheduler is put into
+	  the GlobalContext using FLYSContext.SCHEDULER as key.
+
+	* src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java:
+	  Fetch the Scheduler from GlobalContext.
+
+	* doc/conf/conf.xml: Registered SchedulerSetup as LifetimeListener.

+2011-11-03  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	Added new matching options for theme-mappings to allow more

+
+	Let Qs in Longitudinal Diagram be inactive, initally.
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
+	  (getInitialFacetActivity): Do not let Facets ending with a 'q'

+
+2011-10-25  Felix Wolfsteller	<felix.wolfsteller@intevation.de>
+

+
+2011-10-25  Felix Wolfsteller	<felix.wolfsteller@intevation.de>
+
+	* doc/conf/meta-data.xml: Configured to include correct id to

+
+2011-10-24  Felix Wolfsteller	<felix.wolfsteller@intevation.de>
+

+
+	* src/main/java/de/intevation/flys/exports/WDifferencesCurveGenerator.java
+	  (createSecondAxisRange): Survive parameter-nullness for now.
+	  Added documentation.
+
+2011-10-21	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/themes/ThemeAccess.java:
+	  New. Caching wrapper around an XML document theme. It uses ThemeUtil
+	  to access the values and stores them in instance variable.
+	  Background: ThemeUtil use XPath a lot which is expensive.
+
+	* src/main/java/de/intevation/flys/jfree/StickyAxisAnnotation.java,
+	  src/main/java/de/intevation/flys/exports/XYChartGenerator.java:
+	  Use ThemeAccess to style the annotations.

+	  Removed the spamy debug output.
+
+2011-10-21	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	To obtain the size of a diagram it is rendered twice. The
+	second time the generated image is omitted so the concrete
+	rendered image is not needed. To save CPU cycles in this pass
+	the image is rendered to to /dev/null Graphics2D object.
+
+	* src/main/java/de/intevation/flys/exports/ChartInfoGenerator.java:
+	  Added boolean system property "info.rendering.nop.graphics" (default: false).
+	  With this property set the info rendering is done via a new
+	  NOPGraphics2D opbject which does not render the image.
+
+	* src/main/java/de/intevation/flys/java2d/NOPGraphics2D.java:
+	  New. Implements java.awt.Graphics2D trivial empty methods.
+	  This prevents rendering.
+
+	* src/main/java/de/intevation/flys/jfree/StickyAxisAnnotation.java:
+	  Commented out spamy debug output
+
+2011-10-21  Raimund Renkert <raimund.renkert@intevation.de>
+
+	* src/main/java/de/intevation/flys/jfree/StickyAxisAnnotation.java:
+	  Draw the text background and use orientation attribute.
+
+2011-10-21  Raimund Renkert <raimund.renkert@intevation.de>
+
+	* doc/conf/themes.xml:
+	  Renamed 'textbackground' to 'backgroundcolor' to have 'color' in the

+
+2011-10-20	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/services/CrossSectionKMService.java:
+	  New. Service to lookup the Nth nearest neighbors for a set of given
+	  cross section ids and kms.
+
+	* doc/conf/conf.xml: Registered service.
+
+	* doc/conf/cache.xml: Cache config.
+
+	* src/main/java/de/intevation/flys/artifacts/StaticWKmsArtifact.java,
+	  src/main/java/de/intevation/flys/artifacts/states/WaterlevelPairSelectState.java:

+
+2011-10-20  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/themes.xml: Added main value themes for longitudinal section
+	  charts.
+
+	* src/main/java/de/intevation/flys/themes/ThemeMapping.java: New. This
+	  class stores the name of a facet, the related theme and a pattern
+	  string.
+
+	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
+	  Read the pattern string and store a list of ThemeMapping objects in the
+	  FLYSContext.
+
+	* src/main/java/de/intevation/flys/themes/ThemeFactory.java: Modified
+	  getTheme() which now takes the FLYSContext, the name of a facet and an
+	  optional pattern string. Now, we can have specialized Themes for each
+	  chart type. E.g. the facet "longitudinal_section.w" maps the default
+	  Theme for W lines in longitudinal section charts. If the optional
+	  pattern string matches the pattern ".*(HQ1000)(\D.*)*", the ThemeFactory
+	  will return the Theme "LongitudinalSectionW_HQ1000".
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Use the description of a facet as pattern string to get the relevant
+	  Theme from ThemeFactory.
+
+2011-10-20  Raimund Renkert <raimund.renkert@intevation.de>
+
+	* doc/conf/themes.xml:
+	  Added new theme attributes.

+
+2011-10-19  Felix Wolfsteller	<felix.wolfsteller@intevation.de>
+
+	Fix masterartifact in collections in cases where the original
+	masterartifacts facets do not come first in certain list. Query
+	'backend'/db instead.
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Set 'real' master artifact, defined to be oldest belonging to this
+	  collection.
+
+2011-10-19  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java,

+	  src/main/java/de/intevation/flys/artifacts/states/DGMSelect.java,
+	  src/main/java/de/intevation/flys/artifacts/states/WaterlevelPairSelectState.java:
+	  Modified the method signature of createStaticData() which now also
+	  requires a FLYSArtifact.
+
+	* src/main/java/de/intevation/flys/artifacts/states/WQSelect.java:
+	  Override createStaticData() to create titles for Qs manually - we want
+	  to display the named main values if existing for the selected Qs.
+
+2011-10-19  Raimund Renkert <raimund.renkert@intevation.de>
+
+	* doc/conf/themes.xml:
+	  ComputedDischargeCurveW and ComputedDischargeCurveQ inherit attributes from
+	  theme 'Text'.
+
+2011-10-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	Fix for flys/issue316
+
+	* src/main/java/de/intevation/flys/exports/StyledXYSeries.java: Added
+	  constructor to not sort the data.
+
+	* src/main/java/de/intevation/flys/exports/CrossSectionGenerator.java:
+	  Use the not sorting constructor of StyledXYSeries.
+
+2011-10-19  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/states/WaterlevelState.java:
+	  moved the code to create WSP W and Q facet names to FLYSUtils.
+
+	* src/main/java/de/intevation/flys/utils/FLYSUtils.java: New functions for
+	  creating WSP W and Q facet names and for querying a named main value
+	  based on a given gauge and value. The names of W and Q facets will now
+	  depend on the selected Q and Q mode: if the mode is "q at gauge" and a
+	  named value is found for the given value, the facet's name contains the
+	  named value instead of the value itself.
+
+2011-10-19  Felix Wolfsteller	<felix.wolfsteller@intevation.de>
+
+	Fix datacage configuration to let client load ZUS and flood
+	protections.
+
+	* doc/conf/meta-data.xml: Use 'ids' instead of 'id' to help client.
+

+	  Apply a theme to axis annotations.
+
+2011-10-19	Felix Wolfsteller	<felix.wolfsteller@intevation.de>
+
+	Create (data) Label from data string (client will be adjusted to send
+	the name).
+
+	* src/main/java/de/intevation/flys/artifacts/states/WaterlevelPairSelectState.java:
+	  Create label from input data string, documentation added, junk
+	  removed.
+
+2011-10-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java(zoom):
+	  Do not crash if no axis is given.
+
+2011-10-19  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/exports/ChartGenerator.java: Added
+	  getFormat() which extracts the format string from XML request document.
+
+	* src/main/java/de/intevation/flys/exports/ChartExportHelper.java: Adapted
+	  method signatures of exportImage(), exportSVG() and exportPDF(). All
+	  methods now take a CallContext object which stores extra chart export
+	  parameters.
+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java:
+	  Enabled PDF and SVG chart exports based on the "format" string given in
+	  the XML request document.

+
+
+2011-10-18  Felix Wolfsteller	<felix.wolfsteller@intevation.de>
+
+	Adjusted Datacage-Configuration to fetch "extra longitudinal...."

+
+2011-10-14	Felix Wolfsteller	<felix.wolfsteller@intevation.de>
+
+	Add possibility of programmatic configuration of initial "activity"

+
+	flys/issue353 (W-INFO / Wasserspiegellagenberechnung, Diagramm)
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Adapted the process of collecting outs for Artifacts/Facets. We will now
+	  call OutGenerator.doOut() for each Artifact and Facet - never mind if

+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: Now,
+	  that we walk over every Artifact/Facet, we are able to collect min/max

+	  ranges of x and y axes. The result of this: a chart can have proper axes
+	  set without any data in it.
+
+	* src/main/java/de/intevation/flys/exports/InfoGeneratorHelper.java: Use

+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java:
+	  Instances of this class are now able to store - besides first and second
+	  axes datasets - a list of annotations. This annotations are added to the
+	  plot after the datasets have been added. To support LegendItems for
+	  those annotions, it was necessary to create a the LegendItemCollection

+
+	* src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java:

+	  b) a user-id is given and there is a parameter 'load-system'
+
+	* src/main/java/de/intevation/flys/artifacts/states/WaterlevelSelectState.java:
+	  If the label of the WQKms object specified by the waterlevel selection
+	  begins with a "Q", the label is wrapped into a "W()", e.g. "W(Q=1200)".
+
+2011-09-28  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Made
+	  feed() able to remove existing data items from Artifact's data pool.
+	  Therefore, the value for the item which should be removed needs to an
+	  empty string.
+
+2011-09-28  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	Extracted StringUtil.unbracket from WaterlevelSelectState.strip.
+
+	* src/main/java/de/intevation/flys/artifacts/states/WDifferencesState.java,
+	  src/main/java/de/intevation/flys/artifacts/states/WaterlevelSelectState.java:
+	  Extract and use StringUtil.unbracket, minor doc.
+
+2011-09-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java,
+	  src/main/java/de/intevation/flys/artifacts/MainValuesArtifact.java:
+	  Changed access of getCurrentState() from protected to public.
+
+	* src/main/java/de/intevation/flys/artifacts/CollectionMonitor.java: We
+	  use the configured Outputs instead of the actuel Outputs of an Artifact
+	  to make recommendations, now. This has the bad side effect of giving
+	  recommendations for Outputs that we might _NOT_ be able to produce. But
+	  otherwise, we would not be able to give recommendations for states with
+	  long calculation times that start background threads for calculation (as
+	  WSPLGEN caluclations does).
+
+2011-09-27  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	Enable "auto-scaling" axis for waterlevels in WDifference-plots.
+
+	* src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java:
+	  (createSecondaryAxis, zoomY): Refactored to allow modification in
+	  siblings.
+
+	* src/main/java/de/intevation/flys/exports/WDifferencesCurveGenerator.java:
+	  (createSecondaryAxisRange): Override to achieve expected behavior.
+	  Also adjusted label.
+
+2011-09-27  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	In W-Difference Calculation, respect indices of selected facets.
+
+	* src/main/java/de/intevation/flys/artifacts/states/WDifferencesState.java:
+	  (computeAdvance): Respect index of selected facets.

+
+	flys/issue317: (Querprofil-Diagramm: Referenzen auf CrossSectionApp entfernen)
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
+	  Removed dependency to demo app.
+
+	* src/main/java/de/intevation/flys/artifacts/charts/CrossSectionApp.java:
+	  Refactored to use logic from the models.
+
+	* src/main/java/de/intevation/flys/artifacts/geom/Lines.java:
+	  Moved some logic from the demo app to this model.
+
+2011-09-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/wsplgen/FacetCreator.java: New. Code
+	  from FloodMapState moved to its own class with the intent, to use it in
+	  classes different from FloodMapState.
+
+	* src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java:
+	  Removed the inner class FacetCreator.
+
+	* src/main/java/de/intevation/flys/artifacts/model/WSPLGENJob.java: Stores
+	  an instance of FacetCreator.
+	  NOTE: Maybe we should move the WSPLGEN parameters into an own class
+	  which might be serializable.
+
+	* src/main/java/de/intevation/flys/wsplgen/JobExecutor.java: Use the
+	  FacetCreator instance stored in the WSPLGENJob to create a new WSPLGEN
+	  facet if the calculation was successfully (without errors). Finally, the
+	  facets of FacetCreator are added to the Facet list of the FLYSArtifacts.
+
+2011-09-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java:
+	  Put Artifact in background mode first before starting WSPLGEN, otherwise
+	  a very fast errors (call CallContext.afterBackground() before Artifact is
+	  in Background mode) might lead to an inconsistent state.
+
+	* src/main/java/de/intevation/flys/wsplgen/ProblemObserver.java: Repaired
+	  broken error num parsing.
+
+2011-09-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/wsplgen/ProblemObserver.java: Track

+
+	flys/issue68 (Diagramm: Werte an der Y-Achse benötigen i18n)
+
+	* src/main/java/de/intevation/flys/exports/ChartGenerator.java: Added a
+	  method to retrieve the current/preferred locale specified by CallMeta.
+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java:
+	  Introduced two methods localizeDomainAxis() and localizeRangeAxis().
+	  Both methods of this class override the NumberFormat used to format axes
+	  numbers. Those methods are called by localizeAxes() - which has private
+	  access - for each domain and range axis of the current XYPlot.
+
+2011-09-27	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+

+
+2011-09-26  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java:
+	  The extent of the WSPLGEN result layer is now specified by the extent of
+	  the CrossSectionTracks that matches the start and end kilometer of the
+	  WSPLGEN calculation.
+
+	* src/main/java/de/intevation/flys/utils/GeometryUtils.java: New function
+	  that creates the OpenLayers bounding box based on two Geometries.
+
+2011-09-26  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	Improved w-differences diagram generation with included "absolute"
+	values.
+
+	* src/main/java/de/intevation/flys/exports/WDifferencesCurveGenerator.java:
+	  Fixed one (of two) incorrect labels.
+	  (doWaterlevelOut): Survive non-found gauge, fetch kilometer and w
+	  instead of values for w and q.
+
+2011-09-26  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	Add positional-conflict-awareness when merging Facets for a
+	FLYSArtifactCollection. First come first serve.
+
+	* src/main/java/de/intevation/flys/collections/AttributeWriter.java:
+	  (writeFacets): First, sort incoming facets into 2 groups:
+	  "genuinely new" and "already there", then for each new check
+	  whether the position is already taken. If so, push "up" (position++)
+	  until no conflict exists anymore.
+
+2011-09-26  Ingo Weinzierl <ingo@intevation.de>
+
+	flys/issue296 (Karte: Bezeichnungen verbessern)

+	  Centralized the initialization and shutdown of database connections.
+	  These services now subclass FLYSService which handles the database stuff.
+
+	* src/main/java/de/intevation/flys/artifacts/model/RiverFactory.java: The
+	  current database connection is not closed here - this is done in a
+	  Service or in the CallContext.
+
+	* src/main/java/de/intevation/flys/artifacts/AnnotationArtifact.java: It's
+	  not necessary to create new database connections here. We already have
+	  an existing connection which is initialized by CallContext.
+
+2011-09-22  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/states/DistanceOnlySelect.java:

+
+	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
+	  Defined createItem() here and adapted some method signatures, because I
+	  need the CallContext deeper in code than expected.
+
+	* src/main/java/de/intevation/flys/artifacts/states/WaterlevelSelectState.java:
+	  Write the name of the selected waterlevel into the static DESCRIBE.
+

+
+2011-09-15  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/states/WaterlevelPairSelectState.java:

+
+	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
+	  Added a transform() method. This method should be used to transform

+	  shapefiles only if there are features for it existing.
+
+	* src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java:
+	  A WSPLGEN facet is only created, if the calculation was successfully
+	  added to the Scheduler. A barrier facet is only created if the WSPLGEN
+	  calculation has been added to the scheduler AND if there are digitized
+	  geometries existing.
+
+2011-09-12  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	Copied and slightly modified implementation of guessWaterIncreasing from
+	WQKms to (new) DataUtils. Accidentally commited usage in last commit, to
+	correct orientation of diagram (invert x axis).
+
+	* src/main/java/de/intevation/flys/utils/DataUtils.java:
+	  New file with guessWaterIncreasing implementation from WQKms,
+	  slightly adjusted.
+
+2011-09-12  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	Cosmetics.
+

+
+2011-09-12  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	Added CSV Export for W-Differences.
+
+	* doc/conf/conf.xml: Added Exporter.
+

+	  string message and a progress (in form of step x/y).
+
+	* src/main/java/de/intevation/flys/wsplgen/JobObserver.java: The observer
+	  now writes background messages into the artifact system using the

+	  CalculationMessage here, that makes the WINFOArtifact able to put
+	  progress information into the Artifact's DESCRIBE as well.
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Write
+	  status message and progress information into the DESCRIBE if the

+	  calculations identified by hardcoded uuids!) and register respective facet.
+
+	* src/main/java/de/intevation/flys/exports/WDifferencesCurveGenerator.java:
+	  New file, implementing naive approach to display w-differences.
+
+2011-09-09  Felix Wolfsteller <felix.wolfsteller@intevation.de>

+
+2011-09-08  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/WSPLGENCalculation.java:
+	  New. This sublcass of Calculation saves warnings and errors that occur
+	  while WSPLGEN is running.
+	  Note, that the interface of this class doesn't exactly apply the interface
+	  of Calculation. Maybe, we should generalize this interface!
+

+	  WSPLGEN execution.
+
+	* src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java:

+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Appended
+	  a new attribute 'background-processing' to the DESCRIBE of this
+	  Artifact. Its value is 'true' if this Artifact has started a background
+	  thread which has not finished yet - otherwise it is 'false.
+
+2011-09-07  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/states/RiverAxisState.java,

+	  theme.
+
+2011-09-07  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	In CrossSection Diagram fix subtitle to display the km of which the data is
+	actually displayed (maybe contrasting users wish).
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
+	  (getCrossSectionSnapKm): New method to fetch the actual km of crosssection.
+
+	* src/main/java/de/intevation/flys/exports/CrossSectionGenerator.java:
+	  Add correct km to charts subtitle.
+
+2011-09-07  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+

+	  resolving duplicate code and TODO.
+
+2011-09-07  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	Fix waterline "calculation" at given km. Chosen approach is
+	"head-through-wall".
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
+	  Some refactoring to do the same calculation twice easier and be able
+	  to "cross" waterline against correct profile data.
+
+
+2011-09-07  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	Fix setting of kilometer for profile (not yet waterlevel) of cross section
+	diagram.
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:

+
+	* doc/conf/mapserver/barrier_polygons_class.vm,
+	  doc/conf/mapserver/barrier_lines_class.vm,
+	  doc/conf/mapserver/wsplgen_class.vm: Default Mapserver styles for
+	  barriers and WSPLGEN results. Those styles are only used as long as we
+	  don't have map specific themes (as already used in charts).
+
+	* doc/conf/mapserver/layer.vm: Implements a fallback mechanism for styling
+	  barrier lines/polygons and WSPLGEN results.
+
+	* src/main/java/de/intevation/flys/artifacts/model/LayerInfo.java: Added a
+	  getStyle() method that currently returns "null". This method needs to be
+	  implemented when map themes are introduced.
+
+2011-09-06  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/LayerInfo.java: Renamed

+	  those layers are grouped.
+
+	* doc/conf/mapserver/layer.vm: Renamed attribute based on changes in
+	  LayerInfo and added support for Group-Layers.
+
+2011-09-06  Raimund Renkert <raimund.renkert@intevation.de>

+
+2011-09-05  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/WSPLGENFacet.java:
+	  Removed. We gonna use the WMSLayerFacet until now.
+

+	  Add a WMSLayerFacet after we triggered the Scheduler to start a WSPLGEN
+	  calculation.
+
+2011-09-05  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/mapserver/layer.vm,
+	  doc/conf/mapserver/mapfile.vm: Small bugfixes and style improvements.
+
+	* src/main/java/de/intevation/flys/wsplgen/JobExecutor.java: Trigger the
+	  MapfileGenerator after a WSPLGEN job has finished regardless if it has
+	  been finished successfully or not.
+
+2011-09-05  Ingo Weinzierl <ingo@intevation.de>
+

+	  stuff.
+
+	* doc/conf/mapserver/mapfile.vm,
+	  doc/conf/mapserver/layer.vm: New. A default mapfile template and a
+	  template used for layers.
+
+	* src/main/java/de/intevation/flys/artifacts/model/LayerInfo.java: New.
+	  This class is used while reading WMS layer relevant information from
+	  filesystem.
+
+	* src/main/java/de/intevation/flys/utils/MapfileGenerator.java: New. This
+	  thread is used for creating mapfiles for Mapserver. The MapfileGenerator
+	  runs in daemon mode (own thread) and creates mapfiles based on WMS
+	  layer relevant information read from filesystem.
+
+	* src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java,
+	  src/main/java/de/intevation/flys/utils/FLYSUtils.java: Moved shapefile
+	  specific XPath expressions from FloodMapState to FLYSUtils which is a

+
+2011-09-02  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/wsplgen/JobExecutor.java: New. This
+	  class is used to start WSPLGEN for a specific WSPLGENJob. The System
+	  property "wsplgen.bin.path" tells the JobExecutor where the WSPLGEN
+	  binary is placed (which means in general, the property points to the
+	  'wsplgen.exe').
+
+	* src/main/java/de/intevation/flys/wsplgen/Scheduler.java: New. This
+	  scheduler currently allows to start just a single WSPLGEN Thread. All
+	  WSPLGEN calculations should be started using Scheduler.addJob().
+
+	* src/main/java/de/intevation/flys/wsplgen/JobObserver.java: New. This
+	  thread reads log messages from WSPLGEN and listens for specific
+	  messages. It should be used to update status messages of the WSPLGEN
+	  calculation that is currently running.
+	  There is a System property that tells the JobObserver to log all WSPLGEN
+	  output to log4j: enable WSPLGEN output with "-Dwsplgen.log.output=true".
+
+	* src/main/java/de/intevation/flys/artifacts/model/WSPLGENJob.java: Added
+	  the FLYSArtifact, the current working directory and the CallContext.
+
+	* src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java:
+	  Use the Scheduler to start new WSPLGEN calculations.

+
+	* src/main/java/de/intevation/flys/exports/CrossSectionGenerator.java:
+	  Cleanup, get rid of copied unused method, documentation and more sensible
+	  translations.
+
+	* src/main/resources/messages_de_DE.properties,
+	  src/main/resources/messages_de.properties,
+	  src/main/resources/messages_en.properties,
+	  src/main/resources/messages.properties:
+	  Added cross_section* translations, also cleanups.
+

+
+	* src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java:
+	  Set the Z values of line and polygon barrier geometries. Both barrier
+	  shapefiles will contain 3D geometries now.
+
+2011-09-01  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	Get real data to display in CrossSection (although ignorant of
+	parameterization), making use of the showcase code of the CrossSectionApp-
+	Standalone application.
+
+	* doc/conf/artifacts/winfo.xml: Add new facet (~waterline) to state/out.
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
+	  New methods to get relevant data. So far just takes the first value of
+	  everything and assuming a waterlevel at 130m.
+
+	* src/main/java/de/intevation/flys/artifacts/model/CrossSectionWaterLineFacet.java:
+	  New Facet responsible of water level in cross section.

+
+	* src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java:
+	  Renamed the file for WSPLGEN required waterlevels to "waterlevels.wst".

+
+	* src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java:
+	  A directory for all WSPLGEN stuff is created in computeAdvance() - those

+2011-08-26  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	Also plot "W"-MainValues (on vertical axis), take correct parameters, but

+2011-08-25  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	* src/main/java/de/intevation/flys/exports/ComputedDischargeCurveGenerator.java:

+	  Annotations in LongitudinalSection plots.
+
+2011-08-25  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	* src/main/java/de/intevation/flys/jfree/StickyAxisAnnotation.java:

+	  Added a method that returns a River object based on its database id.
+
+	* src/main/java/de/intevation/flys/artifacts/RiverAxisArtifact.java: The

+
+	* src/main/java/de/intevation/flys/artifacts/MainValuesArtifact.java:

+
+2011-08-24  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	Smaller cosmetics.
+
+	* src/main/java/de/intevation/flys/artifacts/services/DistanceInfoService.java,

+	  Minor fixes, ressurect Facet implementation as inner class.
+
+2011-08-24  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/artifacts/winfo.xml: Moved the input of barriers one state
+	  earlier where the scenario is selected as well.
+
+	* src/main/java/de/intevation/flys/artifacts/states/ScenarioSelect.java:
+	  This state now desires the "map_digitize" UI provider and returns both
+	  items "scenario" and "uesk.barriers" in the dynamic describe part.
+
+	* src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java:
+	  Removed the UI provider and the computeFeed() which is no longer needed,
+	  because there is no more user input in this state.
+
+2011-08-24  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/states/WMSBackgroundState.java,
+	  src/main/java/de/intevation/flys/artifacts/states/RiverAxisState.java:
+	  Repaired broken xpath expressions (the config changed in one of the last
+	  commits) and make use of the variable support in xpath expressions to
+	  replace the rivername.
+
+	* src/main/java/de/intevation/flys/artifacts/WMSBackgroundArtifact.java:

+
+2011-08-23  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:

+
+2011-08-23  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+

+
+2011-08-23  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/conf.xml: Added the MapInfoService and adapted the floodmap
+	  configuration. Now, each river can have its own background wms layer
+	  defined.
+
+	* src/main/java/de/intevation/flys/artifacts/services/MapInfoService.java:
+	  New. This service returns some basic information used to create maps for
+	  a specific river. The name of the desired river needs to be defined at
+	  "/mapinfo/river/text()".
+
+	* src/main/java/de/intevation/flys/artifacts/states/RiverAxisState.java:
+	  Adapted an xpath expression that points to the srid of a river in the
+	  floodmap configuration (which changed).
+
+2011-08-22  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+

+
+2011-08-22  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
+	  Added some code to filter outs/facets by an optional positive list.
+	  This is needed to only expose parts of the facets. This
+	  is needed for artifacts which are loaded into a collection.
+	  TODO: create the filter from the XML document passed at creation
+	  time.
+
+2011-08-22  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Moved all
+	  WINFO specific code to WINFOArtifact. FLYSArtifact is now only revolving
+	  about state affairs.
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: Re-inserted
+	  the specific stuff here.
+

+
+2011-08-22  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/artifacts/winfo.xml: Defined an input value for the GeoJSON
+	  string to save user defined barriers in the map.
+
+	* src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java:
+	  Added a computeFeed() method. In addition, this state now prefers the
+	  "noinput" UI provider.
+
+2011-08-19  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/conf.xml: Each river requires a SRID definition. This
+	  definition is used to transform the river's geometries into the desired
+	  projection.
+
+	* src/main/java/de/intevation/flys/artifacts/model/WMSLayerFacet.java:
+	  This facets are able to save a SRID.
+
+	* src/main/java/de/intevation/flys/artifacts/states/RiverAxisState.java:
+	  The extent that is written into the WMSLayerFacet is determined by the
+	  boundary of the geometry.
+
+	* src/main/java/de/intevation/flys/utils/GeometryUtils.java: New. A
+	  utility class that provides helper functions for geometries. Currently,
+	  one function is defined, that creates a boundary string for OpenLayers.

+2011-08-19  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
+	  Removed CallContext from state validation. It is not needed and hindered

+2011-08-19  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	Fixed flys/issue262
+

+
+2011-08-18  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+
+	* src/main/java/de/intevation/flys/jfree/StickyAxisAnnotation.java:

+
+2011-08-16  Felix Wolfsteller <felix.wolfsteller@intevation.de>

+
+	* src/main/java/de/intevation/flys/artifacts/datacage/Recommendations.java:

+
+	* src/main/java/de/intevation/flys/artifacts/datacage/Recommendations.java:

+
+	* doc/conf/meta-data-template.xml: Deleted.
+	* doc/conf/meta-data-user.xml: New. The user specific template. TODO: Write it!
+	* doc/conf/meta-data-system.xml: New. The system template.
+

+	* src/main/java/de/intevation/flys/artifacts/datacage/Recommendations.java:
+	  New. The logic to fill the templates.
+
+	* src/main/java/de/intevation/flys/artifacts/CollectionMonitor.java:
+	  Adjusted to follow the new call signatures.
+
+	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:
+	  Refactored. Removed the old code and only leave the new service. Following
+	  XPaths are evaluated on the incomming document:
+
+	  "/art:meta/art:artifact-id/@value" The UUID of the artifact. Optional.
+	                                     Used to fill the template enviroment.
+	  "/art:meta/art:user-id/@value"     The UUID of the user. Optional.
+	                                     If given the user specific template is filled.
+	  "/art:meta/art:outs/@value"        The list of outs used to recommend for the
+	                                     various outputs.
+	  "/art:meta/art:parameters/@value"  A list of key/value pairs to inject more
+	                                     filters to the templating.
+
+	* src/main/java/de/intevation/flys/artifacts/datacage/templating/App.java:
+	  Change to follow the new recommendations semantics.
+

+
+	* doc/conf/conf.xml:
+	  Cosmetics, let comments start with a capital and end on a full stop,
+	  removed incorrect comment.
+
+2011-08-03  Felix Wolfsteller <felix.wolfsteller@intevation.de>
+

+
+2011-08-03  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/CollectionMonitor.java(extractOutputNames):
+	  Fixed potential NPE.
+
+2011-08-03  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	Added support for more than one db connection in datacage templating.
+
+	* src/main/java/de/intevation/flys/artifacts/datacage/templating/Builder.java:
+	  Now you can pass a list of named db connections to the build process.
+	  The purpose is to mix more then one database (e.g. the backend db and
+	  the user specific one).
+
+	  To use this feature you can add an "connection" attribute
+	  to <dc:context> with the name of the connection to use.
+	  If no connection name is given the last used is used again.
+	  Initially the first connection in the given list is used.
+	  If the context is left the connection that was active before
+	  will be active again in a stacking manner.
+
+	  When creating NamedConnection objects you can set a boolean flag
+	  if the results coming from the connection should be cached. This
+	  is useful e.g. for the user specific database which runs in-memory
+	  so caching would introduce some superfluous overhead.
+
+	* src/main/java/de/intevation/flys/artifacts/datacage/templating/CompiledStatement.java:
+	  When executing the queries explicitly pass if caching should be used.

+
+	* src/main/java/de/intevation/flys/artifacts/datacage/Datacage.java:

+2011-07-31  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/datacage/Datacage.java:
+	  Delete the artifacts at before initial scan, too. They are independent

+
+	* src/main/resources/datacage-sql/org-h2-driver.properties: Added
+	  statement to delete the artifacts at initial scan, too.
+
+	* src/main/resources/datacage-sql/org-postgresql-driver.properties:

+2011-07-31  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/datacage/Datacage.java:

+
+2011-07-29  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+

+
+2011-07-29  Sascha L. Teichmann <sascha.teichmann@intevation.de>

+2011-07-27  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/datacage/Datacage.java:
+	  New. A artifact database lifetime listener to build the initial

+
+	* doc/conf/conf.xml: Added the datacage to the list of lifetime
+	  listeners.
+
+2011-07-27  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* doc/conf/datacage.sql: Added an explicit table for the outs
+	  of an artifact.
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:

+	  the global context.
+
+2011-07-27  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+

+
+2011-07-26  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+

+	  Uses special features like IDENTITY (autoincrement) typed columns.
+
+	* src/main/java/de/intevation/flys/artifacts/datacage/DBConnection.java:
+	  Pooled connection.
+
+	* pom.xml: Added dependencies to H2 and Apache DBCP.
+
+2011-07-26  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/test/java/de/intevation/flys/artifacts/AppTest.java,
+	  src/main/java/de/intevation/flys/artifacts/App.java: Removed.
+	  This the stupid "Hello, World!" app initially created by the

+
+2011-07-25  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java:
+	  Argh! Usage the DOM was not thread safe (discovered with ab).
+
+2011-07-25  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* doc/conf/meta-data-template.xml: '$recommended' lead to XPath
+	  errors. Using "dc:contains($parameters, 'recommended')" helps.
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java,
+	  src/main/java/de/intevation/flys/artifacts/services/meta/FunctionResolver.java:
+	  Added some debugging.
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/DataCage.java:
+	  Added parameters as 'parameters' to parameters. Usefull to check

+
+2011-07-25  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:

+
+2011-07-25  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:
+	  Made Artifact UUID optional and accept extra parameters, too. This enables
+	  the service to be used without an arttifact and test all filters.
+
+	  <art:meta xmlns:art="http://www.intevation.de/2009/artifacts">
+	     <art:outs value="computed_discharge_curve,floodmap"/>

+	  'contain' accept Maps and collection, too.
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/DataCage.java:
+	  Made artifact option (= null) in recommendations.
+
+2011-07-21  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/CompiledStatement.java:
+	  Moved connection specific into inner class. The enables the reuse of the
+	  compiled statement.
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java: The
+	  SQL statements are now only compiled once at creation time of the builder.
+	  Each connection now reuses them.
+
+2011-07-21  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* doc/conf/cache.xml: Added configuration for static datacage db access.
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/App.java: Using
+	  caches seems to need an explicit System.exit().
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/CompiledStatement.java:
+	  Added support for caching the SQL statements and there results.
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java: Some
+	  clean up. Reordered code for performance. Strip SQL statements more
+	  aggressively.
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/ResultData.java:
+	  Made it Serializable.
+
+	* src/main/java/de/intevation/flys/artifacts/cache/CacheFactory.java:
+	  Introduced system property 'flys.artifacts.cache.config.file' to make
+	  the caching configurable without pulling up the whole stack.
+
+2011-07-22  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Prepared the FLYSArtifactCollection to support the storage of already
+	  loaded recommendations in its attribute document.
+
+2011-07-21  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:
+	  Adjusted to use the DataCage recommendations. The incomming document
+	  can pass the artifacts UUID by '/art:outs/@value' the outs as a
+	  comma separated list in '/art:outs/@value' and optional a set of
+	  filters comma separated in '/art:filters/@value'.
+
+	  If UUID and OUTS are not given the old service is used. This
+	  should be removed as soon as the client uses the new service.
+
+2011-07-21  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/CompiledStatement.java:
+	  Allow '-' in variable names.
+
+2011-07-21  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/meta-data-template.xml: Now, the river-id is really added to
+	  the factory node of the wmsbackground layer.
+
+2011-07-21  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/meta-data-template.xml: Added the river-id to the factory node
+	  of the riveraxis and wmsbackground layer.
+
+2011-07-21  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java,
+	  src/main/java/de/intevation/flys/artifacts/services/MainValuesService.java,
+	  src/main/java/de/intevation/flys/artifacts/services/DistanceInfoService.java,
+	  src/main/java/de/intevation/flys/artifacts/services/RiverService.java:
+	  Adjusted to implement changed Service interface.
+
+2011-07-21  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Refactored
+	  the method that retrieves the Outputs for the Artifact. Now, we are able
+	  to query the Outputs for the current state, and all outputs separately.
+
+	* src/main/java/de/intevation/flys/artifacts/CollectionMonitor.java: The
+	  recommendations provided by this monitor will take the Outputs of the
+	  current state only into account.
+
+2011-07-21  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/meta-data-template.xml: Added conditions for each output type.
+	  Splitted the "floodmap" output into two parts: a recommended one and a
+	  complete one. The recommended part will only build the document tree for
+	  the recommended artifacts; the complete part will build the whole document
+	  tree that is available for a floodmap.
+
+	* src/main/java/de/intevation/flys/artifacts/CollectionMonitor.java:
+	  This Hook now uses the DataCage to generate the recommended artifacts.
+	  The output-defaults configurtion is needless now.
+
+	* doc/conf/output-defaults.xml: Removed. The configuration of recommended
+	  artifacts takes place in meta-data-template.xml.
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/DataCage.java:
+	  Bugfix: the DataCage didn't start working if its builder was NOT null,
+	  but it shouldn't start if the builder IS null.
+
+2011-07-21  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java:
+	  Now it is possible to directly pass a Node as a root to the builder.
+	  The owning document if fetch by Node.getOwnerDocument(). This is
+	  useful if you want to generate the recommendation directly into
+	  an already existing document under a given node.
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/DataCage.java:
+	  Changed the signature of recommend() to accept a node where to
+	  append the recommendations.
+
+2011-07-20  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java:
+	  Added a macro mechanism:
+
+	    <dc:macro name="keine-fuenf">
+	      <dc:text>'5' ist nicht in der Liste der Outs.</dc:text>
+	    </dc:macro>
+	    <dc:call-macro name="keine-fuenf"/>
+	    <dc:call-macro name="keine-fuenf"/>
+	    <dc:call-macro name="keine-fuenf"/>
+
+	  Macros can be defined everywhere in the template
+	  with 'macro'. There bodies can contain all valid elements
+	  including other 'macro's and 'call-macro's. They are
+	  called with their 'name' with 'call-macro'. The control flow
+	  is continued inside the body of the called macro and
+	  will continue right after the calling 'call-macro' when
+	  the macro body is finished.

+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java:
+	  Added a new 'if' construct similiar to XSLT:
+
+	    <dc:if test="not(dc:contains($outs, '5'))">
+	        <dc:text>'5' ist nicht in der Liste der Outs.</dc:text>
+	    </dc:if>
+
+	  The control flow is continued inside the 'if' if the 'test' attribute
+	  as an XPath expression on an empty document evalutes to true.
+	  Else the inside is skipped. There is no 'else'. Use 'choose'/'otherwise'
+	  if you need this.
+
+2011-07-20  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/DataCage.java:
+	  Added a recommend() method to generate recommendations for
+	  a given artifact, outs and extra parameters.
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Added
+	  method to extract all data at once.
+
+2011-07-20  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/FunctionResolver.java:
+	  New. Custom XPath function provider. Provides
+	  'dc:contains(Object [] haystack, Object needle)' by now. Should be
+	  useful to check containments in 'out' lists later.
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java:
+	  Register the FunctionResolver to the evaluated XPaths.
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/App.java:
+	  Added code to parse
+	  "param:a,b,c" to "param" -> new String [] { "a", "b", "c" } to
+	  help testing the 'dc:contains' XPath function.
+
+2011-07-20  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/conf.xml: Added wms configurations for Saar, Mosel and Elbe.
+	  Each river supported by FLYS requires such a WMS configuration. A WMS
+	  should contain layers for the river axis, buildings, kilometer labels
+	  and maybe a background layer as well.
+
+	* src/main/java/de/intevation/flys/artifacts/context/FLYSContext.java:
+	  Added key that is used to store a map of WMS URLs - for each river a
+	  WMS URL.
+
+	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
+	  Parse the river WMS from global configuration.
+
+	* src/main/java/de/intevation/flys/artifacts/states/RiverAxisState.java:
+	  Create WMSLayerFacets with URLs based on the river and the river wms
+	  configuration stored in the FLYSContext.
+
+	* src/main/java/de/intevation/flys/artifacts/WMSBackgroundArtifact.java,
+	  src/main/java/de/intevation/flys/artifacts/RiverAxisArtifact.java:
+	  Adapted the initialize() signature and the method call of computeInit()
+	  which requires a FLYSContext to retrieve the river WMS configurations.
+
+	* src/main/java/de/intevation/flys/artifacts/states/WMSBackgroundState.java,
+	  src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
+	  Added the context object parameter to the computeInit() method.
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Call
+	  initialize() with the context object - which is a FLYSContext or a
+	  CallContext.
+
+2011-07-20  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/App.java:
+	  Check if builder was created properly before using it.
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/StackFrames.java:
+	  Implements now variable provider for XPath expressions.
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/Builder.java:
+	  Added new choose/when/otherwise construct similiar to XSLT
+
+	      <dc:choose>
+	         <dc:when test="$river = 'Mosel'">
+	             <dc:text>Es ist die Mosel.</dc:text>
+	         </dc:when>
+	         <dc:when test="$river = 'Saar'">
+	             <dc:text>Es ist die Saar.</dc:text>
+	         </dc:when>
+	         <dc:otherwise>
+	            <dc:text>Es ist weder Mosel noch Saar.</dc:text>
+	         </dc:otherwise>
+	      </dc:choose>
+
+	  A 'choose' block can contain a list of 'when's and an optional
+	  'otherwise'. For each 'when' the test attribute is evaluated
+	  as an XPath expression on an empty document. The result of
+	  the evaluation is taken as a boolean value. If its value is
+	  true the control flow is continued inside the corresponding
+	  'when' and the other choose elements are not tested.
+	  If the value is values the testing continues with the next
+	  'when'. If no 'test' expression is evaluated to true, the
+	  control flow continues inside the 'otherwise'. If no 'otherwise'
+	  is given nothing happens at all.
+
+2011-07-20  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/conf.xml: Added a config section for floodmaps. Currently, the
+	  background layer's url and layername is defined here.
+
+	* src/main/java/de/intevation/flys/artifacts/states/WMSBackgroundState.java:
+	  Read the background layer configuration from conf.xml. Those values are
+	  used to create the WMSLayerFacet.
+
+2011-07-20  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/states/WMSBackgroundState.java:
+	  The background layer facet will no longer have an extent set.
+
+2011-07-20  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/states/WMSBackgroundState.java,
+	  src/main/java/de/intevation/flys/artifacts/states/RiverAxisState.java:
+	  Set the extent of the created WMSLayerFacets and i18n its descriptions.
+
+	* src/main/resources/messages.properties,
+	  src/main/resources/messages_de_DE.properties,
+	  src/main/resources/messages_en.properties,
+	  src/main/resources/messages_de.properties: Added I18N strings for the
+	  background an river axis layer.
+
+2011-07-20  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/WMSLayerFacet.java:
+	  This facet type has a method to set the extent of a WMS layer. The
+	  extent is written to the facets XML node in toXML() as well.
+
+2011-07-20  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Adapted
+	  the signature of setup() which requires a CallMeta parameter now.
+
+	* src/main/java/de/intevation/flys/artifacts/WMSBackgroundArtifact.java,
+	  src/main/java/de/intevation/flys/artifacts/RiverAxisArtifact.java: Use
+	  the CallMeta object retrieved in setup() to call initialize(). It is now
+	  able to i18n things.
+
+2011-07-20  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/App.java: New.
+	  Standalone app to debug the datacage template. To use in a maven environment:
+
+	  -Dmeta.data.template=PATH_TO_META_DATA-TEMPLATE.XML \
+	  -Dmeta.data.parameters=river:Mosel \
+	  -Dmeta.data.output=OUTPUT.XML \
+	  -Dflys.backend.user=DB_USER \
+	  -Dflys.backend.password=DB_PASSWORD \
+	  -Dflys.backend.url=DB_CONNECTION_URL \
+	  -Dexec.mainClass=de.intevation.flys.artifacts.services.meta.App
+
+2011-07-20  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/services/meta/DataCage.java:
+	  New. First step to factor out the "Datenkorb" logic into a service independent
+	  singleton.
+
+	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:
+	  Uses the "Datenkorb" singleton now.
+
+2011-07-20  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/ManagedFacet.java:
+	  Removed "index" property, because it is already existing in parent
+	  class.
+
+2011-07-19  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:
+	  Improved error handling.
+
+2011-07-19  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/resources/metadata/template.xml: Deleted.
+
+	* doc/conf/meta-data-template.xml: New. Was template.xml
+
+	* doc/conf/conf.xml: Made meta data template configurable.
+
+	* src/main/java/de/intevation/flys/artifacts/services/MetaDataService.java:
+	  Load template from configuration not from resources.
+
+2011-07-19  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/resources/metadata/template.xml: s/[a-z]+-id/db-id/
+	  Make database ids identifiable with unique name "db-id".
+
+2011-07-19  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/ManagedFacet.java:
+	  Override the toXML() method. Subclasses can now write their own XML
+	  representation.
+
+	* src/main/java/de/intevation/flys/artifacts/model/ManagedDomFacet.java:
+	  New. This ManagedFacet uses an Element (DOM) to store the information
+	  about a facet. The intent of this facet type is to represent a facet
+	  stored in an Collection attribute. Different facets can have different
+	  attributes that we need to parse, but the only thing ManagedFacets need
+	  to do, is to adjust the attributes "active" and "position". So, those
+	  values are set directly on the Element, the other attributes aren't
+	  touched.
+
+	* src/main/java/de/intevation/flys/artifacts/model/ManagedFacetAdapter.java:
+	  New. This facet is a wrapper for another facet. This subclass of a
+	  ManagedFacet overrides the toXML() method. The XML representation is
+	  defined by the inner facet that is stored as member variable. The
+	  ManagedFacet specific attributes "artifact", "facet", "pos" and "active"
+	  are added manually.
+
+	* src/main/java/de/intevation/flys/collections/AttributeWriter.java: Uses
+	  the toXML() method to write a facet node into the attribute document.
+
+	* src/main/java/de/intevation/flys/collections/AttributeParser.java: Uses
+	  the ManagedDomFacet to save the information of a facet which is
+	  contained in the attribute part of a Collection's DESCRIBE document.
+
+	* src/main/java/de/intevation/flys/collections/OutputParser.java: Uses the
+	  ManagedFacetAdapter to save a facet, because we want to keep the
+	  specific facet to be able to write its specific XML representation into
+	  the Collection's DESCRIBE document.
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Adapted the XPath of facets stored in the attribute part of the
+	  DESCRIBE.
+
+2011-07-18  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Added a
+	  method that returns the Outputs for the Artifact.
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Adapeted the call of OutputParser.
+
+	* src/main/java/de/intevation/flys/collections/OutputParser.java:
+	  Simplified the code to read the Outputs of Artifacts. This parser will
+	  now longer parse the DESCRIBE documents of the Artifacts, but query the
+	  Outputs via FLYSArtifact.getOutputs() directly.
+
+2011-07-18  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java,
+	  src/main/java/de/intevation/flys/artifacts/StaticFLYSArtifact.java:
+	  Adapted the function call of ProtocolUtils.appendOutputModes().
+
+	* src/main/java/de/intevation/flys/artifacts/model/WMSLayerFacet.java:
+	  Override toXML() to add the URL and layernames to the XML representation
+	  of this facet.
+
+2011-07-18  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/artifacts/wmsbackground.xml,
+	  doc/conf/artifacts/riveraxis.xml: New configurations for an Artifact
+	  that is used as background layer in floodmaps, and an artifact that is
+	  used as layer showing the river axis in a floodmap.
+
+	* doc/conf/output-defaults.xml: New file to configure default artifacts
+	  for specific output states. E.g. the floodmap state recommends a
+	  background layer and a layer displaying the river axis. In suche case,
+	  the floodmap state recommends two artifacts for the two layers.
+
+	* doc/conf/conf.xml: Added new artifacts/artifact-factories and a Hook to
+	  monitor artifacts (-> CollectionMonitor.java).
+
+	* src/main/java/de/intevation/flys/artifacts/model/WMSLayerFacet.java:
+	  New. This facet is used to represent a layer in a map. So, this facet
+	  stores information about a WMS URL and the layer names provided by this
+	  WMS.
+
+	* src/main/java/de/intevation/flys/artifacts/model/FacetTypes.java: Added
+	  facet types for the wmsbackground and riveraxis.
+
+	* src/main/java/de/intevation/flys/artifacts/states/WMSBackgroundState.java,
+	  src/main/java/de/intevation/flys/artifacts/WMSBackgroundArtifact.java:
+	  New. An artifact and its default state. The intent of these classes is
+	  to generate WMSLayerFacets which represent background layers in maps.
+
+	* src/main/java/de/intevation/flys/artifacts/states/RiverAxisState.java,
+	  src/main/java/de/intevation/flys/artifacts/RiverAxisArtifact.java: New.
+	  An artifact and its default state. The intent of these classes is to
+	  generate WMSLayerFacets which represent layers that display a river
+	  axis.
+
+	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
+	  Added the INIT ComputeType.
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Added a
+	  case for the INIT ComputeType while computing data.
+
+2011-07-18  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java:
+	  Added a method computeInit() which is called to initialize data/facets
+	  after an artifact has been created.
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Repaired
+	  broken XPath.
+
+2011-07-14  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/CollectionMonitor.java:
+	  Removed the code to generate new artifacts. Instead of creating new
+	  artifacts automatically, we decided to suggest creating new artifacts
+	  from specific types. Therefore, the DESCRIBE document of the artifacts
+	  is extended with a node that contains recommended artifact types.
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
+	  FLYSArtifacts might be setup with the identifier of an other
+	  FLYSArtifact. Subclasses are able to override a method called
+	  initialize(Artifact, GlobalContext). This might be helpful to extract
+	  required values or clone artifacts.
+
+2011-07-14  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
+	  Adapted the signature of createArtifactContext() - it returns an
+	  instance of GlobalContext now.
+
+2011-07-14  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/geom/Lines.java:
+	  Debugged the water fill algorithm. Added a lot of logging.
+
+	* src/main/java/de/intevation/flys/artifacts/charts/CrossSectionApp.java:
+	  Added a text field to give a water level to fill in.
+
+2011-07-14  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java,
+	  src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Moved code
+	  to create the output modes based on the given facets to FLYSArtifact. In
+	  addition, FLYSArtifact got a new method that returns a specific input
+	  value as string.
+
+	* src/main/java/de/intevation/flys/artifacts/CollectionMonitor.java: New.
+	  This hook monitors the "post-feed" and "post-advance". If the monitored
+	  Artifact's state has configured recommended artifacts, this hook will
+	  create new Artifacts.
+
+	  TODO: We have to add the UUIDs of the new Artifacts to the DESCRIBE
+	  document of the artifact to let the client know, that there are new
+	  recommended Artifacts.
+
+	* src/main/java/de/intevation/flys/artifacts/StaticFLYSArtifact.java: New.
+	  This Artifact is the base class for Artifacts, that represent static
+	  data. E.g. this could be a decoration theme in a chart or a background
+	  layer in the map.
+
+	* src/main/java/de/intevation/flys/artifacts/states/OutputState.java: New.
+	  This state might be used as base class for states, that doesn't require
+	  any user input, but only provide static Facets added by a computeFeed()
+	  operation. So, subclasses need to implement computeFeed() only.
+
+2011-07-13  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/charts/CrossSectionApp.java:
+	  New. Standalone Swing-App to test cross sections from database without the
+	  hassles of our complete software stack. Runnable from a maven environment:
+
+	  $ mvn -e \
+	    -Dflys.backend.user=DB_USER \
+		-Dflys.backend.password=DB_PASSWD \
+		-Dflys.backend.url=DB_CONNECTION_URL \
+		-Dexec.mainClass=de.intevation.flys.artifacts.charts.CrossSectionApp \
+		exec:java
+
+	  You can set the river to be used with the system property 'river'.
+	  Defaults to 'Mosel'.
+
+	* src/main/java/de/intevation/flys/artifacts/model/WSPLGENFacet.java:
+	  Removed superfluous imports.
+
+2011-07-13  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/artifacts/winfo.xml: The FloodMapState has a new Outputmode
+	  called "floodmap" now.
+
+	* src/main/java/de/intevation/flys/artifacts/model/WSPLGENFacet.java: New.
+	  This facet is used to generate WSPLGEN results.
+
+	* src/main/java/de/intevation/flys/artifacts/model/FacetTypes.java: Added
+	  the WSPLGENFacet.
+
+	* src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java:
+	  This state will now generate WSPLGENFacets.
+
+2011-07-12  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/geom/Lines.java:
+	  Fixed corner case.
+
+2011-07-11  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/geom/Lines.java: New.
+	  fillWater() generates a list of wet lines for a given profile and a
+	  given water level.
+
+2011-07-08  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: The
+	  Outputs created while generating the DESCRIBE document will now have the
+	  'type' member set.
+
+	* src/main/java/de/intevation/flys/collections/OutputParser.java: Read the
+	  'type' member from DESCRIBE document.
+
+2011-07-06  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/artifacts/winfo.xml: Removed a typo.
+
+2011-07-06  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/DataFacet.java:
+	  DataFacet are now able to store the ID of the state which has created
+	  this Facet.
+
+	* src/main/java/de/intevation/flys/artifacts/states/WaterlevelState.java:
+	  Initialize DataFacets with the ID of this state. This is necessary to
+	  renew the waterlevel data if it is no longer existing in the cache.
+
+2011-07-06  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/ReportFacet.java: A
+	  report facet can now store the state's id and the artifact's hash value
+	  when it has been created.
+
+	* src/main/java/de/intevation/flys/artifacts/states/WaterlevelState.java:
+	  Initialize the ReportFacet and WaterlevelFacet with state id and hash
+	  information. This has been necessary to retrieve reports and waterlevels
+	  in states after this one - in states that we need to enter for floodmap
+	  parameterization.
+
+2011-07-05  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/states/WaterlevelGroundDifferences.java:
+	  Changed the desired UI provider.
+
+2011-07-05  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/artifacts/winfo.xml: Added the option to continue the
+	  waterlevel parameterization with the intent to create flood maps.
+
+	* src/main/java/de/intevation/flys/artifacts/states/WaterlevelState.java:
+	  This state is no longer a final state. The user has the option to
+	  continue with the parameterization for flood maps based on the current
+	  waterlevel. Therefore, this states desires the "continue" UI provider.
+	  Clients should recognice this to just step to the next state or display
+	  a button that lets the user step to the next state manually.
+
+	* src/main/java/de/intevation/flys/artifacts/states/FloodplainChoice.java,
+	  src/main/java/de/intevation/flys/artifacts/states/FloodMapState.java,
+	  src/main/java/de/intevation/flys/artifacts/states/ScenarioSelect.java,
+	  src/main/java/de/intevation/flys/artifacts/states/DGMSelect.java,
+	  src/main/java/de/intevation/flys/artifacts/states/ProfileDistanceSelect.java,
+	  src/main/java/de/intevation/flys/artifacts/states/WaterlevelGroundDifferences.java:
+	  New. These states are used to parameterize a further calculation type:
+	  flood map.
+
+	* src/main/resources/messages.properties,
+	  src/main/resources/messages_de_DE.properties,
+	  src/main/resources/messages_en.properties,
+	  src/main/resources/messages_de.properties: Required strings for the
+	  flood maps states.
+
+2011-07-04  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	Fix(?) for flys/issue114
+
+	* src/main/java/de/intevation/flys/artifacts/model/WQ.java:
+	  Make guessing a bit more robust.
+
+2011-07-03  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	Added the math needed to calculate "W-Differenzen" in "Laengsschnitten".
+	Needs testing!
+
+	* src/main/java/de/intevation/flys/artifacts/model/NamedObject.java:
+	  Made it an interface to be usable in more than one inheritance chain.
+
+	* src/main/java/de/intevation/flys/artifacts/model/NamedObjectImpl.java:
+	  Implements the NamedObject interface and is the new base class of
+	  WQ and WKmsImpl.
+
+	* src/main/java/de/intevation/flys/artifacts/model/WKms.java:
+	  New. Interface to associate kms with ws.
+
+	* src/main/java/de/intevation/flys/artifacts/model/WQKms.java:
+	  Changed the base class to NamedObjectImpl. Renamed getKms(int)
+	  to getKm(int) to make clear it return a single scalar value
+	  and fullfil the WKms interface.
+
+	* src/main/java/de/intevation/flys/artifacts/model/WKmsImpl.java:
+	  New. Implements the WKms interface. Intended to be a lightweight
+	  datastore for "zusaetzliche Laengsschnitte" and as results
+	  of the WKmsOperations.
+
+	* src/main/java/de/intevation/flys/artifacts/model/WQ.java:
+	  Changed base class to NamedObjectImpl.
+
+	* src/main/java/de/intevation/flys/artifacts/math/WKmsOperation.java:
+	  New. Operations on WKms data.
+	  Currently only the SUBTRACTION operation is implemented. This
+	  one is needed to calculate the "W-Differenzen". The operation
+	  is insensitive about the km directions of the datasets. Missing
+	  values are interpolated linear.
+
+	* src/main/java/de/intevation/flys/exports/DischargeLongitudinalSectionGenerator.java,
+	  src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java:
+	  Adjusted to satisfy the signature change of WQKMs.
+
+2011-07-01  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/exports/StyledXYSeries.java: New. This
+	  XYSeries stores the style information that should be used to render this
+	  series. These information are stored as raw XML documents. A public
+	  method can be used to apply those style information to a
+	  XYLineAndShapeRenderer.
+
+	  Note: The only two attributes currently supported by StyledXYSeries
+	  items are "linesize" and "linecolor".
+
+	* doc/conf/themes.xml: Added some more basic themes for the four
+	  calculation methods.
+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: This
+	  generator now tries to apply themes for all series contained in the
+	  chart. If a series is no instance of StyledXYSeries, the default
+	  renderer is used.
+
+	* src/main/java/de/intevation/flys/exports/DischargeLongitudinalSectionGenerator.java,
+	  src/main/java/de/intevation/flys/exports/DurationCurveGenerator.java,
+	  src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java,
+	  src/main/java/de/intevation/flys/exports/ComputedDischargeCurveGenerator.java,
+	  src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java:
+	  Removed the code that had been introduced to adapt renderers statically.
+	  Now, each of these concrete ChartGenerators instantiates StyledXYSeries
+	  items to put the curves into the chart. Those items contain style
+	  information now!

+
+	flys/issue135 (Diagramm: Trotz abgeschalteter Themen bleiben Beschriftungen bestehen)
+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: The way
+	  to store datasets has changed. Until this revision, the concrete
+	  generators managed their own datasets. E.g. the
+	  DischargeLongitudinalSectionGenerator had three datasets: w, q and
+	  corrected w. Now, there are just two datasets, managed by this base
+	  generator - one dataset for the first Y axis and one dataset for the
+	  second Y axis. This makes it easier to remove axes, that have no data to
+	  be displayed. All concrete chart generators have to add their XYSeries
+	  using two methods: addFirstAxisSeries() and addSecondAxisSeries().
+
+	* src/main/java/de/intevation/flys/exports/DischargeLongitudinalSectionGenerator.java,
+	  src/main/java/de/intevation/flys/exports/DurationCurveGenerator.java,
+	  src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java,
+	  src/main/java/de/intevation/flys/exports/ComputedDischargeCurveGenerator.java,
+	  src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java:
+	  Those concrete chart generators no longer manage datasets themself but
+	  they use the two methods described above, to plot the data to the first
+	  or second Y axis.
+

+
+	flys/issue159 (WINFO: Radiobutton - Ortsauswahl bei "W für ungleichwertigen Abflusslängsschnitt" entfernen)
+
+	* doc/conf/artifacts/winfo.xml: Changed the kilometer range input for
+	  calculation 4. This calculation type requires a kilometer range. So,
+	  after choosing the calculation 4, the transition model leads to a state
+	  that just allows the input of a kilometer range with no option to
+	  enter locations.
+
+	* src/main/java/de/intevation/flys/artifacts/states/ComputationRangeState.java:
+	  New. A base state for the kilometer selection for calculations. The
+	  target of this state is to provide facets for the duration curves.
+
+	* src/main/java/de/intevation/flys/artifacts/states/DistanceSelect.java:
+	  New. This state is used to enter a kilometer range. The difference to
+	  the LocationDistanceSelect state is, that there is no option to enter
+	  locations.
+
+	* src/main/java/de/intevation/flys/artifacts/states/RangeState.java:
+	  Improved this state to be the base state for calculation ranges.
+
+	* src/main/java/de/intevation/flys/artifacts/states/LocationSelect.java
+	  src/main/java/de/intevation/flys/artifacts/states/LocationDistanceSelect.java
+
+	* src/main/java/de/intevation/flys/artifacts/states/WQSelect.java: This
+	  state no longer inherits from RangeState which now is used as base
+	  state for kilometer ranges.
+
+	* src/main/resources/messages.properties,
+	  src/main/resources/messages_de_DE.properties,
+	  src/main/resources/messages_en.properties,
+	  src/main/resources/messages_de.properties: Added new i18n strings for
+	  the DistanceSelect state.
+
+2011-06-28  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* pom.xml: Downgraded Trove to 1.1-beta-5, because the new
+	  later ones are removed from the maven repos.
+
+	  The functionality we need is in 1.1 so this downgrade should

+
+2011-06-27  Sascha L. Teichmann <sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/WQ.java:
+	  Guessing increaing w is not based on direct neighbors any more.
+	  The second to be compared with is choosen by random of

+
+	* src/main/java/de/intevation/flys/artifacts/model/WQ.java(guessWaterIncreasing):
+	  Added a method to guess based on a given factor of the size (default 0.05)

+
+	* src/main/java/de/intevation/flys/artifacts/model/Calculation4.java:
+	  Fixed the way the gauge was found for a given interval.
+	  The old way does not work because it was just tested if
+	  the station point was inside the segments which is not
+	  necessarily true. The obvious solution to simply check
+	  the overlapping intervals does not work either because
+	  the gauge ranges touch each other and so more than
+	  one gauge are returned in these cases. The River.maxOverlap()
+	  is now used to find the gauge with the max overlapping
+	  range.

+
+	Fix for flys/issue147
+
+	* src/main/java/de/intevation/flys/artifacts/model/Calculation1.java:

+	* src/main/java/de/intevation/flys/artifacts/model/Calculation1.java:
+	  Allow an explicit reference km to enable calculation "am Pegel".
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
+	  If a calculation "am Pegel" is done, take start km of the
+	  calculation range and find the gauge in which range it is located.
+	  Take the station of the gauge as the reference km. If no gauge
+	  is found the calcualtion falls back to calculation "auf freier Strecke".
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java:
+	  Replaced another inefficient attribute extraction via XPath
+	  with direct DOM access.

+
+	* doc/conf/cache.xml: 200 elements in memory for "computed.values" are enough,

+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java:
+	  Changed the zoom operation. The zoom values defined in the chart request
+	  document are no longer absolute values for a specific axis. Those values
+	  represent percental values for the start and end point of x and y axes.
+	  E.g. a chart has three axes with the following ranges:
+	    - x axis  :  0 - 10
+	    - y axis 1: 20 - 40
+	    - y axis 2: 40 - 90
+	    - zoom values for x: 0.1 - 0.9 (10% - 90%)
+	    - zoom values for y: 0.2 - 0.8 (20% - 80%)
+	  The produced chart will have the following ranges:
+	    - x axis  :  1 - 9
+		- y axis 1: 24 - 36
+		  y axis 2: 50 - 80

+
+	* src/main/java/de/intevation/flys/artifacts/model/WQCKms.java:

+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
+	  Refactored range code a bit. Needs more work.
+
+2011-06-01  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/exports/InfoGeneratorHelper.java:
+	  Interchange the lower and upper x value of the chart if the x-axis is
+	  inverted before the matrix values are computed. Now, the matrix is able
+	  to work with charts that have an inverted x-axis.
+
+2011-06-01  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/exports/ChartInfoGenerator.java: New. A
+	  chart info generator generates a document that contains meta information
+	  for a specific chart. Concrete instances of this abstract class need to
+	  instantiate concrete ChartGenerators and dispatch nearly all methods of
+	  an OutGenerator (init(), doOut(), setMaster()) to this instance. The
+	  generate() method is implemented in the ChartInfoGenerator itself. It
+	  creates a chart with help of the ChartGenerator instance and builds a
+	  document that contains meta information of this chart.
+
+	* src/main/java/de/intevation/flys/exports/InfoGeneratorHelper.java: New.
+	  This helper is used to create the chart info document. At the moment,
+	  the only information that is included in this document is a
+	  transformation matrix to transform image coordinates into chart
+	  coordinates.
+
+	  NOTE: The transformation matrix creation needs some work to support
+	  charts with inverted X axis.
+
+	* src/main/java/de/intevation/flys/exports/LongitudinalSectionInfoGenerator.java,

+	  Concrete instances of ChartInfoGenerator that create the chart info for
+	  the currently supported chart types.
+
+	* doc/conf/conf.xml: Registered new OutGenerators.
+
+2011-05-31  Ingo Weinzierl <ingo@intevation.de>

+
+2011-05-30	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* doc/conf/cache.xml: Introduced cache to store the distance info per river.
+	  This boosts performance in following ab setup from  3.61 to 39.91 requests/secs.
+
+	  $ ab -c 20 -n 1000 -p distances.xml http://127.0.0.1:8181/service/distanceinfo

+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Moved the code part that skips themes right after the part that sets the
+	  master artifact for the OutGenerator. We need this master artifact to
+	  display empty charts - master artifact is used to create titles and
+	  axes.
+
+2011-05-27  Ingo Weinzierl <ingo@intevation.de>
+

+2011-05-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/collections/AttributeParser.java:
+	  Repaired broken XPath expressions to find the output modes in an
+	  attribute document of a collection.
+
+	* src/main/java/de/intevation/flys/collections/AttributeWriter.java: This
+	  writer will now create a document that has a root node art:attribute.
+	  Before these changes, the document's root node was art:outputs which is
+	  part of the attribute document but not the right root node.
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:

+
+	Work on flys/issue69
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:

+	  of gauges intersected by the given kilometer range.
+
+	* src/main/java/de/intevation/flys/artifacts/states/DischargeLongitudinalSection.java:

+	  New. This state is reached if the user chose the computed discharge
+	  curve.
+
+	* src/main/java/de/intevation/flys/exports/ComputedDischargeCurveGenerator.java:
+	  New. This is only a stub implementation at the moment. This
+	  OutGenerator should create computed discharge curves later. It extends
+	  the DischargeCurveGenerator which should do the same stuff for discharge
+	  curves for gauges.
+
+	* src/main/java/de/intevation/flys/exports/ComputedDischargeCurveExporter.java:
+	  New. This is only a stub implementation at the moment. This OutGenerator
+	  should create the exports of the discharge curve computation.
+
+2011-05-03  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/artifacts/winfo.xml: Added a new output mode for the duration

+
+	* doc/conf/conf.xml: Added a new OutGenerator to export duration curve
+	  computations.
+
+	* src/main/java/de/intevation/flys/exports/AbstractExporter.java: New.

+	* src/main/java/de/intevation/flys/exports/WaterlevelExporter.java: Moved
+	  the most code to export to CSV into the AbstractExporter.
+
+	* src/main/java/de/intevation/flys/exports/DurationCurveExporter.java:

+
+	* doc/conf/conf.xml: Added a new OutGenerator to export waterlevels.
+
+	* src/main/java/de/intevation/flys/exports/WaterlevelExporter.java: New.
+	  This OutGenerator exports the data of a waterlevel computation. Note:
+	  It is necessary to specify the desired facet (e.g.

+
+	* pom.xml: Added a dependency to OpenCSV.
+
+2011-05-03  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Introduced an "export" output target. If the target is "export", a

+	  that determines which facets are written to the output.
+
+2011-05-03  Ingo Weinzierl <ingo@intevation.de>
+

+
+	* src/main/java/de/intevation/flys/artifacts/model/MainValuesFactory.java:
+	  Added a function to retrieve tuples of (day, q) based on a given gauge -
+	  these tuples are necessary for creating duration curves.

+
+2011-05-02  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/artifacts/winfo.xml: Enhanced the transition model to reach the
+	  final state for creating duration curves.
+
+	* src/main/java/de/intevation/flys/artifacts/states/LocationSelect.java:
+	  New. This state should be reached to just insert an array of locations.
+
+	* src/main/java/de/intevation/flys/artifacts/states/DurationCurveState.java:
+	  New. This state is reached if the duration curve calculation is
+	  selected.
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Adjusted
+	  getDistance() so that it takes care on inserted locations - not just
+	  inserted ranges.
+
+2011-05-02	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/cache/CacheFactory.java:

+
+	* src/main/java/de/intevation/flys/artifacts/model/WQKms.java:
+	  Added a constructor to create backing trove datastructure
+	  with the right capacity.
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
+	  Move allocation of result ws out of km loop.
+
+2011-05-02  Ingo Weinzierl <ingo@intevation.de>
+
+	* doc/conf/artifacts/winfo.xml: Added two further data items in the WQ
+	  selection state. Those items are necessary to store the information
+	  about the selected mode (range/single selection) and  the values of the
+	  single selection.
+
+	* src/main/java/de/intevation/flys/artifacts/states/DefaultState.java: If
+	  there is no value for a data item, this item is not written into the
+	  static DESCRIBE part.
+
+	* src/main/java/de/intevation/flys/artifacts/states/RangeState.java,
+	  src/main/java/de/intevation/flys/artifacts/states/LocationDistanceSelect.java:
+	  Renamed the method to validate upper and lower values.
+
+	* src/main/java/de/intevation/flys/artifacts/states/WQSelect.java: This
+	  state can now handle values inserted in the single selection. Therefore,
+	  new validate methods has been added.
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: The
+	  methods getWs() and getWs() take care on the values inserted in the
+	  single insert mode of the client which enables the user to insert single
+	  W and Q.
+
+2011-05-02	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
+	  Repaired getQForW() by calculating indices on right dimension.
+
+2011-05-02  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: New
+	  methods for retrieving selected W values (getWs()).
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java: The
+	  method for retrieving waterlevel data takes care on selected Ws, now.
+	  The selected Ws are transformed using the DischargeTables.getQForW()
+	  into Q values.
+
+2011-05-02  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
+	  Removed an unused parameter 'result' of getQForW().
+
+2011-05-02  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java: Removed
+	  the getDataset() method and replaced it with a addDataset() method.
+	  On this way, concrete subclasses of this OutGenerator can have multiple
+	  datasets (e.g. different datasets for W and Q). This abstract method is
+	  called after the chart generation is finished.
+
+	* src/main/java/de/intevation/flys/exports/LongitudinalSectionGenerator.java,
+	  src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java:
+	  Both classes implement the addDataset() method. The
+	  LongitudinalSectionGenerator has already multiple datasets for W and Q.
+	  Both are added to the chart - both have an own range axis.
+
+2011-05-01	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:

+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Bugfix: Now, curves for Q values are drawn into a longitudinal section
+	  chart as well. Therefore, it was necessary to change the datastructure
+	  of the inner class ThemeList that stores all themes included in a chart
+	  in an ordered list (stored in a java.util.Vector now).
+
+2011-04-29  Ingo Weinzierl <ingo@intevation.de>

+	  Double values.
+
+	* pom.xml: Added the GNU Trove dependency.
+
+2011-04-29  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/exports/OutGenerator.java: Added the

+	  Call init() after a Transition has been created.
+
+2011-04-28  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/collections/AttributeWriter.java:
+	  Bugfix: Introduced a <art:outputs> node in the attribute document of a
+	  Collection that contains further <art:output> nodes - instead of having
+	  multiple <art:output> nodes at toplevel of the document.
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Adapted the XPath to retrieve the outputs in the attribute document of a
+	  Collection.
+
+2011-04-28	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* contrib/visualize-transitions.xsl: Added to create a

+
+2011-04-28  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java::
+	  A lot of new methods to retrieve the theme of a facet - used while
+	  creating the output of a facet/artifact. If a facet has no theme yet, it
+	  is initialized.
+
+2011-04-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/collections/AttributeParser.java,

+
+2011-04-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/exports/ChartGenerator.java: New. An
+	  abstract OutGenerator that might be used to create chart output. Some
+	  basic things that are equal in all charts should be done here!
+
+	* src/main/java/de/intevation/flys/exports/DischargeCurveGenerator.java:
+	  This OutGenerator no longer implements the OutGenerator directly, but it
+	  extends the ChartGenerator now.
+
+2011-04-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  Restructured the out() operation of a collection: Now, we collect a list
+	  of artifacts/facets and use this for the OutGenerator. Its doOut()
+	  method gets the attribute of an artifact - the position and the active
+	  state is managed by the Collection itself.
+
+2011-04-26  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/ManagedFacet.java: New.
+	  a specialized facet that stores information about its position and its
+	  state (active/inactive) in an output of a collection.
+
+	* src/main/java/de/intevation/flys/collections/AttributeParser.java: New.
+	  This parser takes the attributes (XML) of a collection and extracts the
+	  contained outputs with its facets. The result is a Map<String, Output>.
+
+	* src/main/java/de/intevation/flys/collections/OutputParser.java: New.
+	  This parser is used to query the artifact's DESCRIBE and to extract the
+	  supported outputs. The result is a Map<String, Output>.
+
+	* src/main/java/de/intevation/flys/collections/AttributeWriter.java: New.
+	  This writer merges the outputs contained in an attribute of a collection
+	  with the outputs of a collection's artifacts.
+
+	* src/main/java/de/intevation/flys/collections/FLYSArtifactCollection.java:
+	  The attributes of a collection are written into its DESCRIBE document
+	  now. The OutputParser and AttributeParser are used to read the supported
+	  attributes by the collection and its artifacts - the AttributeWriter is
+	  used to merge both attributes and create a final attribute document.
+
+2011-04-26  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/context/FLYSContext.java,

+	  The facet-2-theme mappings are initialized at startup and stored in the
+	  FLYSContext.
+
+	* src/main/java/de/intevation/flys/themes/ThemeFactory.java: Added a
+	  function that retrieves a theme from FLYSContext based on its name.
+
+2011-04-22	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
+	  Corrected a silly c&p mistake.
+
+2011-04-22	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/math/BackJumpCorrector.java:
+
+	  Implementation of the "Ruecksprungkorrektur" to be done in
+	  "W fuer angepassten Abflusslaengschnitt".
+
+	  All tests show the expected results. In some corner cases the
+	  algorithm described in the "Anwenderhandbuch" chapter 3.3.4.3 "Korrektur"
+	  has some definition shortcomings:
+
+	  a - What should happend when you cannot find point 2 because
+	      you cannot step back one quarter from point 3 because there
+	      is no data there any more (river too short in this direction)?
+	      The implemented algorithm raises point 3' only to an
+	      according factor. E.g. If you can step back the whole quarter
+	      distance the elevation is the full quarter. If you can
+	      step back only the half of the quarter the elevation is
+	      only an eighth.
+
+	  b - If the water heights between point 2 and 3 are constant then
+	      the algorithm will produce a spline interpolation that
+	      lowers those values. Is this intended?
+
+	  For real data the back jumps are expected to be more in the middle
+	  of the distance ranges so the corner cases are maybe not so
+	  important.
+
+	* src/main/java/de/intevation/flys/artifacts/states/RiverSelect.java:
+	  Removed superfluous import.
+
+2011-04-21  Ingo Weinzierl <ingo@intevation.de>
+

+
+	* doc/conf/themes.xml: New. A first small theme configuration.
+
+	* doc/conf/conf.xml: Added a link to the theme configuration.
+
+	* src/main/java/de/intevation/flys/artifacts/context/FLYSContext.java:
+	  Defined a key that is used to store a themes map in the FLYSContext.
+
+	* src/main/java/de/intevation/flys/artifacts/context/FLYSContextFactory.java:
+	  The theme configuration is read at startup and the themes are stores in
+	  the FLYSContext.
+
+2011-04-21  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/themes/Theme.java,
+	  src/main/java/de/intevation/flys/themes/DefaultTheme.java:

+
+	* src/main/java/de/intevation/flys/themes/ThemeField.java,
+	  src/main/java/de/intevation/flys/themes/DefaultThemeField.java:
+	  New. The interface and its default implementation that represents fields
+	  in themes. A theme might be "Lines" and one of its field might be
+	  "Color" or "Size".
+
+	* src/main/java/de/intevation/flys/themes/ThemeFactory.java: A factory
+	  that creates new themes based on a theme configuration.
+
+2011-04-20	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
+	  Implementation of "Abflusskurve/Abflusstafel" calculation.
+
+	  Added method interpolateWQ() which takes an km and results in a
+	  tuple of two double arrays containing the w/q values interpolated
+	  between the surrounding w/q values of the table.
+	  w values are interpolated linear, q values with a cubic spline.
+
+	  Drawing w over q gives you the discharge table at the given km.
+
+	  !!! This code needs testing !!!
+
+2011-04-20	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* pom.xml: Added dependency to Apache Commons Math 2.2 (Apache License 2.0)
+
+2011-04-20	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:

+	  Fixed broken HQL statement.
+
+2011-04-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
+	  add a method interpolateW() which takes an array of
+	  q values and returns an equal sized array of w values.
+	  This is essentially the "Wasserstand/Wasserspiegellagen" calculation
+	  of desktop FLYS.
+
+	  If you want to do a calculation with given w values you have
+	  to convert the w values with DischargeTables.getQForW() first.
+
+	  !!! This code needs heavy testing !!!
+
+2011-04-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:
+	  We need a getQForW() method and not getWForQ() because when
+	  doing a "Wasserstand/Wasserspiegellagen" calculation with given
+	  w values these values need to be translated to q values with
+	  the master discharge table.
+
+2011-04-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/DischargeTables.java:

+2011-04-18	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:

+2011-04-18  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/artifacts/FLYSArtifact.java: Changed

+	  It should return true, if the data of the State is fine, otherwise it
+	  should raise an exception.
+
+	  NOTE: The exceptions are not translated in the server but in the client!
+
+	* src/main/java/de/intevation/flys/artifacts/states/RangeState.java: New.
+	  This abstract class exists to provide some methods for handling ranges.
+	  Currently, there is a method that validates a given range based on

+
+	* src/main/java/de/intevation/flys/artifacts/states/LocationDistanceSelect.java,
+	  src/main/java/de/intevation/flys/artifacts/states/WQSelect.java:

+2011-09-19  RELEASE 2.5
+
+    NEW:
+
+        * Introduced the concept of a "datacage": the datacage is a service that
+          provides a list of chart themes that fit to a given chart type. The
+          service accepts a user uuid, the uuid of a master Artifact, the name
+          of the output type and a set of further string parameters. In general,
+          we distinguish between user-specific datacage and system-specific
+          datacage:
+          The user-specific datacage returns themes provided by old
+          calculations computed by the user.
+          The system-specific datacage returns themes that might be generated
+          using the data stored in the flys-backend.
+
+        * Introduced a database used by the datacage that stores information
+          about Artifacts, their outputs and their facets. This database
+          requires synchronization with the Artifact database. The intent of
+          this database is to have a fast access to data stored in Artifacts.
+
+        * Introduced a mechanism to clone existing Artifacts (with or without
+          restrictions). For cloning an Artifact, it is necessary to specify the
+          UUID of a "model Artifact". The clone will be based on that model by
+          extracting all required data from it.
+
+        * Introduced "recommendations": recommendations are themes in charts or
+          maps (Artifacts/Facets) that should be added automatically to an
+          existing chart/map. They are provided by the datacage.
+
+        * Introduced new Artifact types to provide further chart themes:
+          - Annotations
+          - Mainvalues
+
+        * Introduced new Facet type WMSLayerFacet. This type stores all required
+          information (server url, layer names, layer extent, layer srid) to
+          display a WMS layer in a WMS client.
+
+        * Introduced a new chart output "Querprofildiagramm". This output
+          calculates a waterlevel and displays it as single line together with
+          one or more cross section lines ("Querprofilspuren").
+
+        * Introduced a new chart output "W-Differenzen". This output calculates
+          waterlevel differences based on at least two waterlevels (a
+          "W-Differenzen" output can consist of more than a single waterlevel
+          difference calculation). Each waterlevel difference calculation
+          results in three chart themes: two W curves and a W-Differences curve.
+
+        * Introduced a new output "Ãœberschwemmungskarte". The visualization of
+          this output is a map. One of the map's layers is a WMS layer that
+          displays the calculation result of WSPLGEN (external C++ tool).
+
+        * Improved the rendering process of chart themes: the styles configured
+          for themes are now used.
+
+        * Improved the DistanceInfoService: it supports filters to filter the
+          type of items returned by this service (reduces the number of returned
+          items of course).
+
+        * Introduced a CSV export for "W-Differenzen".
+
+        * Downgraded GNU Trove to 1.1-beta-5 (later versions have been removed
+          from maven repositories).
+
+
+    FIXES:
+
+        * flys/issue135 (Diagramm: Trotz abgeschalteter Themen bleiben Beschriftungen bestehen)
+
+        * flys/issue159 (WINFO: Radiobutton - Ortsauswahl bei "W für ungleichwertigen Abflusslängsschnitt" entfernen)

+
+
+
+2011-06-27  RELEASE 2.4
+
+    NEW:
+
+        * Finalized the Facet concept: output modes and the output generation
+          are now based on facets. Facets are created dynamically by an Artifact
+          based on the results of a calculation.
+
+        * Introduced a report mechanism that gives feedback of calculation
+          problems.
+
+        * Introduced output modes that generate XML document with calculation
+          report information.
+
+        * Introduced deactivated themes in charts: such themes are not rendered.
+
+        * Introduced a cache to store distance info per river.
+
+        * Introduced output modes that generate XML documents which contain meta
+          information of charts as axes ranges, data ranges and a transformation
+          matrix that allows to transform image coordinates into chart
+          coordinates.
+
+        * Added support for zoom values in Chart output modes.
+
+        * Added support for min/max values in DESCRIBE documents.
+
+        * Added "Oberkante" and "Unterkante" columns to distance info service.
+
+        * Added a new export mode to save data in AT format.
+
+        * Improved performance while storing/loading Q values of WST columns.
+
+        * Improved the WQ values validation for calculation 1 & 4.
+
+        * Improved calculations to work independent of "from"/"to" order of
+          kilometer ranges.
+
+        * Improved the input of WQ values for calculation 1. We distinguish
+          between a selected Q at a given gauge or a selected Q that doesn't
+          base on a given gauge.
+
+        * Allow "from" to be greater than "to" in kilometer ranges.
+
+        * Write default values of the user into the Artifact's DESCRIBE
+          document (flys/issue40).
+
+
+    FIXES:

+
+        * flys/issue90 Removed space between chart axes and chart area.
+
+        * flys/issue93 Renamed calculation 4.
+
+        * flys/issue103 Append values selected by the user in the correct format
+          to the DESCRIBE document of Artifacts (uses i18n).
+
+        * flys/issue147
+
+        * flys/issue150 Invert the X axis correctly for charts of type
+          calculation 1 & 4.
+
+        * flys/issue154 Repaired computed discharge curve that broke after the
+          facets had been finalized.
+
+        * flys/issue157 Discharge curve charts (computed an static) will now
+          have a lower x value set to "1".
+
+        * flys/issue161 Longitudinal section chart's second Y axis will
+          initially start at Q=0.
+
+        * flys/issue164 Improved input validation for WQ input of calculation 4.
+
+        * flys/issue172 Duration curve charts will now have a lower x value set
+          to "0".
+
+        * flys/issue173 Fixed broken gauge determination in calculation 4.
+
+        * flys/issue174 Repaired broken upper margin between chart data and
+          chart border in longitudinal section charts.
+
+        * Added missing "Corrected W" facet for results of calculation 4.
+
+        * Map datasets in duration curve charts to the correct axes.
+
+        * Fixed broken XPath to detect output modes in an attribute document of
+          a Collection.
+
+        * Feed operation will no longer save data if the validation of the given
+          values failed.
+
+
+
+2011-05-19  RELEASE 2.3.1
+
+    NEW:
+
+        * New export format for waterlevels: WST.

+
+
+
+2011-05-13  RELEASE 2.3
+
+    NEW:
+
+        * Initial release of the artifacts for FLYS. Currently there is a single
+          WINFO artifact for the following computations:
+          - waterlevels
+          - discharge curves
+          - duration curves
+          - discharge longitudinal section curves
+
+        * Configuration is placed in doc/conf/conf.xml
+
+        * WINFO Artifact specific configuration is placed in
+          doc/conf/artifacts/winfo.xml
+
+        * So called 'OutGenerators' produce different types of output.
+          Currently, the flys-artifacts are able to produce charts and exports.
+          Each output type has to be configured in conf.xml.
+
+        * New chart types:
+          - discharge curves (dt. 'Abflusskurven am Pegel')
+          - computed discharge curves (dt. 'Abflusskurve')
+          - longitudinal section curves (dt. 'Längsschnitte')
+          - duration curves (dt. 'Dauerlinie')
+          - discharge longitudinal section curve (dt. 'W bei
+            ungleichmäßigem Abflusslängsschnitt')
+
+        * New exports:
+          - csv of waterlevels
+          - csv of duration curves
+          - csv of computed discharge curves
+          - csv of discharge longitudinal section
+
+        * New services that provides:
+          - supported rivers
+          - main values of a gauge
+          - range information of a river
+          - meta information of a river
+
+        * Caching of computation relevant values
+
+        * Initial model to support chart specific themes (theme.xml)
+
+
+    LIMITATIONS:
+
+        * Charts are not rendered using the themes in theme.xml

+# KNOWN ISSUES:
+#	* The following occurs:
+#		file with: \usepackage{named}\bibliographystyle{named}
+#		Compile
+#		change to: \usepackage{apalike}\bibliographystyle{apalike}
+#		Compile again -- BARF!
+#
+#		The workaround: make clean-nographics; make
+#
+#		Note that we may not be able to fix this.  LaTeX itself barfs
+#		on this, not the makefile.  The very first invocation of LaTeX
+#		(when something like this has happened) reads the existing .aux
+#		file and discovers invalid commands like \citeauthoryear that
+#		are only valid in the package that was just removed.  It then
+#		tries to parse them and explodes.  It's not at all clear to me
+#		how to fix this.  I tried removing the .aux files on the first
+#		run of LaTeX, but that necessarily requires more subsequent
+#		rebuilds on common edits.  There does not appear to be a
+#		graceful solution to this issue.

+# CHANGES:
+# Chris Monson (2010-04-08):
+# 	* Bumped version to 2.2.0-rc1
+# 	* Added back in the rst_style_file stuff that got broken when switching
+# 		rst -> tex to use the script mechanism
+# Chris Monson (2010-03-23):
+#	* Bumped version to 2.2.0-beta8
+#	* Work on issue 76: bad backtick escape for some sed versions, failure
+#		to clear out the hold buffer when outputting MISSING comment.
+#		- Backed out 2>&1 to &> (doesn't work in sh)
+#		- Backed out using . to source variables
+# Chris Monson (2010-03-22):
+# 	* Bumped version to 2.2.0-beta7
+# 	* Issue 72: Fix latex/bibtex invocation order for annotated bib styles
+# 	* Fixed informational output to reflect which LaTeX run we're on
+# 	* Fixed graphic detection to include graphics that are already there in
+# 		.d files
+# 	* Tightened up the .d file output to only make .d depend on graphic
+# 		*source* files.  This means that building foo.d no longer
+# 		builds all of the graphics files on which foo.tex depends.
+# 		Had to use .SECONDEXPANSION trickery to make it work.
+# 	* Changed get-graphics to only accept a stem.
+# 	* Fixed build-once logic for scripted .tex to work better
+# 	* Made get-inputs sed script more maintainable.
+# 	* Moved Makefile.ini import up higher.
+# 	* Changed bare stems to not recursively invoke make
+# 	* Updated diff output to be more silent everywhere
+# 	* Added a MISSING comment to the .d file if stuff isn't found - forces
+# 		removal of .1st.make file, which often forces it to try again.
+# 	* Fixed broken graphics-target function
+# 	* Added sleep to .d file generation when stuff is missing - if it
+# 		builds too fast, make doesn't realize it needs to be reloaded,
+# 		and thus never discovers some deeper dependencies (especially
+# 		evident when graphics are included from scripted include
+# 		files).
+# Chris Monson (2010-03-17):
+# 	* Bumped version to 2.2.0-beta6
+# 	* Fixed bareword builds to actually work (requires static patterns)
+# 	* Fixed colorization to work with new paragraph stuff
+# Chris Monson (2010-03-17):
+# 	* Bumped version to 2.2.0-beta5
+# 	* Fixed graphic detection to be much more focused - splits log file
+# 		into paragraphs before doing pattern matching.
+# 	* Fixed make foo to work properly (recursively calls make foo.pdf)
+# 	* Fixed gpi -> pdf generation to not waste time building .eps *after*
+# 		the pdf already exists.
+# 	* Changed log copies to include MAKE_RESTARTS as part of the name.
+# 	* Fixed missing include file detection (also makes use of the paragraph
+# 		stuff) to detect missing scripted include files.
+# Chris Monson (2010-03-16):
+# 	* Bumped version to 2.2.0-beta4
+# 	* issue 70: .pdf not moved out of the way properly on first
+# 		compilation, resulting in early error detection failure.
+# 	* issue 74: fixed broken error on missing .aux files: the
+# 		implementation was masking real errors.
+# Chris Monson (2010-03-15):
+# 	* Bumped version to 2.2.0-beta3
+# 	* issue 71: Made the tput dependency optional
+# 	* issue 73: Made .tex targets not pull in .d files (building them from
+# 		scripts should not require a .d)
+# 	* issue 74: Output a much saner error when a .aux file is not produced
+# 		(e.g., when you are typing "make" without arguments in a
+# 		directory with included .tex files that are not named with
+# 		._include_.)
+# Chris Monson (2010-03-11):
+# 	* Bumped version to 2.2.0-beta2
+# 	* Fixed clean-graphics to get rid of intermediate .eps files that may
+# 		be hanging around
+# 	* Added an automatic setting to use eps terminals in pdflatex mode for
+# 		gnuplot if it doesn't understand pdf.
+# 	* issue 66: Removed grayscale generation via magic suffix.  Grayscale
+# 		generation is now only available via GRAY=1
+# 	* issue 68: Added explicit handling of LC_ALL for locale-aware tools
+# 		like "sort"
+# Chris Monson (2010-03-10):
+# 	* Bumped version to 2.2.0-beta1
+# 	* Fixed success message to handle output message in different places
+# 	* Added name of produced file to success message

+# 	* Add ability to have a single $HOME/.latex-makefile/Makefile.ini for
+# 		all invocations
+# 	* Reworked graphic inclusion detection so that extensions need not be
+# 		specified for either build strategy (e.g.,
+# 		\includegraphics{test1.eps} -> \includegrahpics{test1})
+# 	* Changed log format to include filenames and line numbers
+# Chris Monson (2010-02-04):
+# 	* Bumped version to 2.1.43
+# 	* All of the following are for issue 63 (thanks to mojoh81):
+# 	* Added documentation about fixing Makefile.ini default target
+# 	* Added perl and python script targets
+# 	* Fixed run logic to allow included .tex files to be scripted (the
+# 		run-again logic now detects missing .tex files, and the MV
+# 		command has been switched out for a command that only invokes
+# 		MV if the files exist)
+# 	* Changed scripted generation to only run once per make invocation
+# 	* Added dependency on expr
+# Chris Monson (2010-01-19):
+# 	* Bumped version to 2.1.42
+# 	* issue 62: Added .brf extension to cleanable files (backrefs)
+# Chris Monson (2010-01-07):

+# Chris Monson (2009-03-27):

+# 	* Bumped version to 2.1.20
+# 	* Added manual pstex compilation support (run make all-pstex first)
+# 	* Removed all automatic pstex support.  It was totally breaking

+# 		I still suggest that psfrag be used instead.
+# Chris Monson (2007-10-16):
+# 	* Bumped version to 2.1.7

+#	* Bumped version to 2.0a7
+#	* Added .dvi and .ps files as secondary files.
+#	* Fixed handling of multiple run detection when includeonly is in use.
+#	* Added code to flatten .aux files.
+#	* Added more files as .SECONDARY prerequisites to avoid recompilation.
+#	* Fixed the inputs generation to be much simpler and to use pipes.
+#	* Added the dependency graph directly into the makefile.
+#	* Changed flatten-aux to remove \@writefile \relax \newlabel, etc.
+#	* Undid pipe changes with sed usage (BSD sed doesn't know -f-).
+#	* Added a _check_programs target that tells you what your system has.
+#	* Fixed an error in colorization that made unnecessary errors appear
+#	* Added view targets.
+#	* Updated help text.
+#	* Augmented cookies so that .aux can trigger .bbl and .dvi rebuilds
+#	* Added more informative error handling for dvips and ps2pdf
+# Chris Monson (2006-04-02):
+#	* Bumped version to 2.0a6
+#	* Added indirection to .bbl dependencies to avoid rebuilding .bbl files
+#	* Streamlined the diff invocation to eliminate an existence test
+#	* Removed special shell quote escape variables
+#	* Moved includes to a more prominent location
+#	* Fixed .inputs.make to not contain .aux files
+#	* Fixed embedding to use a file instead of always grepping.
+#	* Added *.make.temp to the list of cleanable files
+#	* Fixed Ruby.  It should now be supported properly.
+#	* Now differentiate between all, default, and buildable files.
+#	* Fixed to bail out on serious errors.
+#	* Revised the handling of includable files.  Still working on it.
+# Chris Monson (2006-03-31):
+#	* Bumped version to 2.0a5
+#	* Fixed a bug with LaTeX error detection (there can be spaces)
+#	* Added .bbl support, simplifying everything and making it more correct
+#	* Refactored some tests that muddy the code
+#	* Did a little cleanup of some shell loops that can safely be make loops
+#	* Added support for graphviz .dot files
+#	* Made _all_programs output easier to read
+#	* Added the ruby support that has long been advertised
+#	* Font embedding was screwed up for PostScript -- now implicit
+#	* Changed the generation of -gray.gpi files to a single command
+#	* Changed any make-generated file that is not included from .d to .make
+# Chris Monson (2006-03-30):
+#	* Bumped version to 2.0a4
+#	* Fixed a bug with very long graphics file names
+#	* Added a todo entry for epsfig support
+#	* Fixed a bug paper size bug: sometimes more than one entry appears
+#	* Fixed DVI build echoing to display the number instead of process ID
+#	* DVI files are now removed on first invocation if ANY file is missing
+#	* Added a simple grayscale approach: if a file ends with -gray.gpi, it
+#		is created from the corresponding .gpi file with a special
+#		comment ##GRAY in its header, which causes coloring to be
+#		turned off.
+#	* Fixed a bug in the handling of .tex.sh files.  For some reason I had
+#		neglected to define file stems for scripted output.
+#	* Removed a trailing ; from the %.graphics dependencies
+#	* Added dvips embedding (I think it works, anyway)
+# Chris Monson (2006-03-29):
+#	* Bumped version to 2.0a3
+#	* Fixed error in make 3.79 with MAKEFILE_LIST usage
+#	* Added the presumed filename to the _version output
+#	* Added a vim macro for converting sed scripts to make commands
+#	* Added gpi dependency support (plotting external files and loading gpi)
+#	* Allow .gpi files to be ignored if called .include.gpi or .nobuild.gpi
+#	* Fixed sed invocations where \+ was used.  BSD sed uses \{1,\}.
+# Chris Monson (2006-03-28):
+#	* Bumped version to 2.0a2
+#	* Added SHELL_DEBUG and VERBOSE options
+#	* Changed the default shell back to /bin/sh (unset, in other words)
+#	* Moved .PHONY declarations closer to their targets
+#	* Moved help text into its own define block to obtain better formatting
+#	* Removed need for double-entry when adding a new program invocation
+#	* Moved .SECONDARY declaration closer to its relevant occurrence
+#	* Commented things more heavily
+#	* Added help text about setting terminal and output in gnuplot
+#	* Created more fine-grained clean targets
+#	* Added a %.graphics target that generates all of %'s graphics
+#	* Killed backward-compatible graphics generation (e.g., eps.gpi=gpi.eps)
+#	* For now, we're just GPL 2, not 3.  Maybe it will change later
+#	* Made the version and svninfo into variables
+# Chris Monson (2006-03-27):
+#	* Bumped version to 2.0a1
+#	* Huge, sweeping changes -- automatic dependencies
+

+# BSD SED NOTES
+#
+# BSD SED is not very nice compared to GNU sed, but it is the most

+# it or require people to install GNU sed.  It seems like the GNU
+# requirement isn't too bad since this makefile is really a GNU makefile,
+# but apparently GNU sed is much less common than GNU make in general, so
+# I'm supporting it here.
+#
+# Sad experience has taught me the following about BSD sed:
+#
+# 	* \+ is not understood to mean \{1,\}
+# 	* \| is meaningless (does not branch)
+# 	* \n cannot be used as a substitution character
+# 	* ? does not mean \{0,1\}, but is literal
+# 	* a\ works, but only reliably for a single line if subsequent lines
+# 		have forward slashes in them (as is the case in postscript)
+#
+# For more info (on the Mac) you can consult
+#
+# man -M /usr/share/man re_format
+#
+# And look for the word "Obsolete" near the bottom.

+# 1) If a line has a single ending paren, delete it to make a blank line (so
+#	that we catch the first error, which is not always preceded by a blank
+#	line).
+# 2) Ensure that the last line of the file gets appended to the hold buffer,
+# 	and blank it out to trigger end-of-paragraph logic below.
+# 3) When encountering a blank line (LaTeX output helpfully breaks output on
+# 	newlines)
+# 	a) swap the hold buffer (containing the paragraph) into the pattern buffer (putting a blank line into the hold buffer),
+# 	b) remove the newline at the beginning (don't ask),
+# 	c) apply any colorizing substitutions necessary to ensure happiness.
+# 	d) get the newline out of the hold buffer and append it
+# 	e) profit! (print)
+# 4) Anything not colorized is deleted, unless in verbose mode.

+# p = V(1-S)

+# Generate all of the information needed to get dependencies
+# As a side effect, this creates a .dvi or .pdf file (depending on the build
+# strategy).  We need to be sure to remove it if there are errors.  Errors can
+# take several forms and all of them are found within the log file:
+#	* There was a LaTeX error
+#	* A needed file was not found
+#	* Cross references need adjustment
+#
+# Behavior:
+#	This rule is responsible for generating the following:
+#	%.aux
+#	%.d
+#	%.aux.make
+#	%.(pdf|dvi).1st.make (the .pdf or .dvi output file, moved)
+#
+#	Steps:
+#
+#	Run latex
+#	Move .pdf or .dvi somewhere else (make no judgements about success)
+#	Flatten the .aux file into another file
+#	Add source dependencies
+#	Add graphic dependencies
+#	Add bib dependencies
+#
+#	Create cookies for various suffixes that may represent files that
+#	need to be read by LaTeX in order for it to function properly.
+#
+#	Note that if some of the dependencies are discovered because they turn
+#	up missing in the log file, we really need the .d file to be reloaded.
+#	Adding a sleep command helps with this.  Otherwise make is extremely
+#	nondeterministic, sometimes working, sometimes not.

+# Generates a number of possible output files from a LaTeX document and its
+# various dependencies.  Handles .bib files, \include and \input, and .eps
+# graphics.  All dependencies are handled automatically by running LaTeX over
+# the source.
+#
+# USAGE:
+#
+#    make [GRAY=1] [VERBOSE=1] [SHELL_DEBUG=1] <target(s)>
+#
+# STANDARD OPTIONS:
+#    GRAY:
+#        Setting this variable forces all recompiled graphics to be grayscale.
+#        It is useful when creating a document for printing.  The default is
+#        to allow colors.  Note that it only changes graphics that need to be
+#        rebuilt!  It is usually a good idea to do a 'make clean' first.
+#
+#    VERBOSE:
+#        This turns off all @ prefixes for commands invoked by make.  Thus,
+#        you get to see all of the gory details of what is going on.
+#
+#    SHELL_DEBUG:
+#        This enables the -x option for sh, meaning that everything it does is
+#        echoed to stderr.  This is particularly useful for debugging
+#        what is going on in $$(shell ...) invocations.  One of my favorite
+#        debugging tricks is to do this:
+#
+#        make -d SHELL_DEBUG=1 VERBOSE=1 2>&1 | less
+#
+# STANDARD AUXILIARY FILES:
+#
+#      Makefile.ini
+#
+#          This file can contain variable declarations that override various
+#          aspects of the makefile.  For example, one might specify
+#
+#          neverclean := *.pdf *.ps
+#          onlysources.tex := main.tex
+#          LATEX_COLOR_WARNING := 'bold red uline'
+#
+#          And this would override the neverclean setting to ensure that pdf
+#          and ps files always remain behind, set the makefile to treat all
+#          .tex files that are not "main.tex" as includes (and therefore not
+#          default targets).  It also changes the LaTeX warning output to be
+#          red, bold, and underlined.
+#
+#          There are numerous variables in this file that can be overridden in
+#          this way.  Search for '?=' to find them all.
+#
+#          Also, you can put arbitrary targets into it if, for example, you
+#          want your source built from something else, e.g.:
+#
+#          generated.tex: generating_script.weird_lang depA depB
+#          	./generating_script.weird_lang > $$@
+#
+#          Note that if you are not careful, you can override the default
+#          target (what happens when you type "make" without arguments), so if
+#          you do use Makefile.ini, you probably want to start it with
+#          something like the following line:
+#
+#          default: all
+#
+#          Since the first target in any makefile is automatically the default,
+#          and the makefile already has a sensible "all" target, this will do
+#          what you want.
+#
+#          The Makefile.ini is imported before *anything else* is done, so go
+#          wild with your ideas for changes to this makefile in there.  It
+#          makes it easy to test them before submitting patches.
+#
+# STANDARD ENVIRONMENT VARIABLES:
+#
+#      LATEX_COLOR_WARNING		'$(LATEX_COLOR_WARNING)'
+#      LATEX_COLOR_ERROR		'$(LATEX_COLOR_ERROR)'
+#      LATEX_COLOR_UNDERFULL		'$(LATEX_COLOR_UNDERFULL)'
+#      LATEX_COLOR_OVERFULL		'$(LATEX_COLOR_OVERFULL)'
+#      LATEX_COLOR_PAGES		'$(LATEX_COLOR_PAGES)'
+#      LATEX_COLOR_BUILD		'$(LATEX_COLOR_BUILD)'
+#      LATEX_COLOR_GRAPHIC		'$(LATEX_COLOR_GRAPHIC)'
+#      LATEX_COLOR_DEP			'$(LATEX_COLOR_DEP)'
+#      LATEX_COLOR_SUCCESS		'$(LATEX_COLOR_SUCCESS)'
+#      LATEX_COLOR_FAILURE		'$(LATEX_COLOR_FAILURE)'
+#
+#   These may be redefined in your environment to be any of the following:
+#
+#      black
+#      red
+#      green
+#      yellow
+#      blue
+#      magenta
+#      cyan
+#      white
+#
+#   Bold or underline may be used, as well, either alone or in combination
+#   with colors:
+#
+#      bold
+#      uline
+#
+#   Order is not important.  You may want, for example, to specify:
+#
+#   export LATEX_COLOR_SUCCESS='bold blue uline'
+#
+#   in your .bashrc file.  I don't know why, but you may want to.
+#
+# STANDARD TARGETS:
+#
+#    all:
+#        Make all possible documents in this directory.  The documents are
+#        determined by scanning for .tex and .tex.sh (described in more detail
+#        later) and omitting any file that ends in ._include_.tex or
+#        ._nobuild_.tex.  The output is a set of .pdf files.
+#
+#        If you wish to omit files without naming them with the special
+#        underscore names, set the following near the top of the Makefile,
+#        or (this is recommended) within a Makefile.ini in the same directory:
+#
+#        	includes.tex := file1.tex file2.tex
+#
+#        This will cause the files listed to be considered as include files.
+#
+#        If you have only few source files, you can set
+#
+#        	onlysources.tex := main.tex
+#
+#        This will cause only the source files listed to be considered in
+#        dependency detection.  All other .tex files will be considered as
+#        include files.  Note that these options work for *any* source type,
+#        so you could do something similar with includes.gpi, for example.
+#        Note that this works for *any valid source* target.  All of the
+#        onlysources.* variables are commented out in the shipping version of
+#        this file, so it does the right thing when they simply don't exist.
+#        The comments are purely documentation.  If you know, for example, that
+#        file.mycoolformat is supported by this Makefile, but don't see the
+#        "onlysources.mycoolformat" declared in the comments, that doesn't mean
+#        you can't use it.  Go ahead and set "onlysources.mycoolformat" and it
+#        should do the right thing.
+#
+#    show:
+#        Builds and displays all documents in this directory.  It uses the
+#        environment-overridable value of VIEW_PDF (currently $(VIEW_PDF)) to
+#        do its work.
+#
+#    all-graphics:
+#        Make all of the graphics in this directory.
+#
+#    all-pstex (only for BUILD_STRATEGY=latex):
+#        Build all fig files into pstex and pstex_t files.  Gray DOES NOT WORK.
+#
+#    all-gray-pstex (only for BUILD_STRATEGY=latex):
+#    	 Build all fig files into grayscale pstex and pstex_t files.
+#
+#    all-dot2tex:
+#    	 Build all dot files into tex files.
+#
+#    show-graphics:
+#        Builds and displays all graphics in this directory.  Uses the
+#        environment-overridable value of VIEW_GRAPHICS (currently
+#        $(VIEW_GRAPHICS)) to do its work.
+#
+#    clean:
+#        Remove ALL generated files, leaving only source intact.
+#        This will *always* skip files mentioned in the "neverclean" variable,
+#        either in this file or specified in Makefile.ini:
+#
+#        	neverclean := *.pdf *.ps
+#
+#       The neverclean variable works on all "clean" targets below, as well.
+#
+#    clean-graphics:
+#        Remove all generated graphics files.
+#
+#    clean-backups:
+#        Remove all backup files: $(backup_patterns)
+#        (XFig and other editors have a nasty habit of leaving them around)
+#        Also removes Makefile-generated .temp files
+#
+#    clean-tex:
+#        Remove all files generated from LaTeX invocations except dependency
+#        information.  Leaves graphics alone.
+#
+#    clean-deps:
+#        Removes all auto-generated dependency information.
+#
+#    clean-auxiliary:
+#        Removes extra files created by various targets (like the dependency
+#        graph output).
+#
+#    clean-nographics:
+#        Cleans everything *except* the graphics files.
+#
+#    help:
+#        This help text.

+# DEBUG TARGETS:
+#
+#    _all_programs:
+#        A list of the programs used by this makefile.
+#
+#    _check_programs:
+#        Checks your system for the needed software and reports what it finds.
+#
+#    _check_gpi_files:
+#        Checks the .gpi files in the current directory for common errors, such
+#        as specification of the terminal or output file inside of the gpi file
+#        itself.
+#
+#    _dependency_graph:
+#        Outputs a .dot file to stdout that represents a graph of LaTeX
+#        dependencies.  To see it, use the _show_dependency_graph target or
+#        direct the output to a file, run dot on it, and view the output, e.g.:
+#
+#        make _dependency_graph > graph.dot
+#        dot -T ps -o graph.eps graph.dot
+#        gv graph.eps
+#
+#    _show_dependency_graph:
+#        Makes viewing the graph simple: extracts, builds and displays the
+#        dependency graph given in the _dependency_graph target using the value
+#        of the environment-overridable VIEW_POSTSCRIPT variable (currently set
+#        to $(VIEW_POSTSCRIPT)).  The postscript viewer is used because it
+#        makes it easier to zoom in on the graph, a critical ability for
+#        something so dense and mysterious.
+#
+#    _all_sources:
+#        List all .tex files in this directory.
+#
+#    _sources:
+#        Print out a list of all compilable sources in this directory.  This is
+#        useful for determining what make thinks it will be using as the
+#        primary source for 'make all'.
+#
+#    _scripts:
+#        Print out a list of scripts that make knows can be used to generate
+#        .tex files (described later).
+#
+#    _all_stems:
+#        Print a list of stems.  These represent bare targets that can be
+#        executed.  Listing <stem> as a bare target will produce <stem>.pdf.
+#
+#    _includes:
+#        A list of .d files that would be included in this run if _includes
+#        weren't specified.  This target may be used alone or in conjunction
+#        with other targets.
+#
+#    _graphic_outputs:
+#        A list of all generated .eps files
+#
+#    _env:
+#        A list of environment variables and their values.  If supported by
+#        your version of make, also a list of variables known to make.
+#
+# FILE TARGETS:
+#
+#    %, %.pdf:
+#        Build a PDF file from the corresponding %.tex file.
+#
+#        If BUILD_STRATEGY=pdflatex, then this builds the pdf directly.
+#        Otherwise, it uses this old-school but effective approach:
+#
+#            latex -> dvips -> ps2pdf
+#
+#        The BUILD_STRATEGY can be overridden in Makefile.ini in the same
+#        directory.  The default is pdflatex.
+#
+#        Reasons for using latex -> dvips include the "psfrag" package, and the
+#        generation of postscript instead of PDF.  Arguments for using pdflatex
+#        include "new and shiny" and "better supported."  I can't argue with
+#        either of those, and supporting them both didn't turn out to be that
+#        difficult, so there you have it.  Choices.
+#
+#    %._show:
+#        A phony target that builds the pdf file and then displays it using the
+#        environment-overridable value of VIEW_PDF ($(VIEW_PDF)).
+#
+#    %._graphics:
+#        A phony target that generates all graphics on which %.pdf (or %.dvi)
+#        depends.
+#
+#    %.ps (only for BUILD_STRATEGY=latex):
+#        Build a Postscript file from the corresponding %.tex file.
+#        This is done using dvips.  Paper size is automatically
+#        extracted from the declaration
+#
+#        \documentclass[<something>paper]
+#
+#        or it is the system default.
+#
+#        If using beamer (an excellent presentation class), the paper
+#        size is ignored.  More on this later.
+#
+#    %.dvi (only for BUILD_STRATEGY=latex):
+#        Build the DVI file from the corresponding %.tex file.
+#
+#    %.ind:
+#        Build the index for this %.tex file.
+#
+#    %.gls:
+#        Build the nomenclature glossary for this %.tex file.
+#
+#    %.nls:
+#        Build the (newer) nomenclature file for this %.tex file.
+#
+#    %.eps:
+#        Build an eps file from one of the following file types:
+#
+#       .dot    : graphviz
+#       .gpi    : gnuplot
+#       .fig    : xfig
+#       .xvg    : xmgrace
+#       .svg    : scalable vector graphics (goes through inkscape)
+#       .png    : png (goes through NetPBM)
+#       .jpg	: jpeg (goes through ImageMagick)
+#       .eps.gz : gzipped eps
+#
+#       The behavior of this makefile with each type is described in
+#       its own section below.
+#
+#    %.pstex{,_t} (only for BUILD_STRATEGY=latex):
+#       Build a .pstex_t file from a .fig file.
+#
+# FEATURES:
+#
+#    Optional Binary Directory:
+#        If you create the _out_ directory in the same place as the makefile,
+#        it will automatically be used as a dumping ground for .pdf (or .dvi,
+#        .ps, and .pdf) output files.
+#
+#        Alternatively, you can set the BINARY_TARGET_DIR variable, either as a
+#        make argument or in Makefile.ini, to point to your directory of
+#        choice.  Note that no pathname wildcard expansion is done in the
+#        makefile, so make sure that the path is complete before going in
+#        there.  E.g., if you want to specify something in your home directory,
+#        use $$HOME/ instead of ~/ so that the shell expands it before it gets
+#        to the makefile.
+#
+#    External Program Dependencies:
+#        Every external program used by the makefile is represented by an
+#        ALLCAPS variable at the top of this file.  This should allow you to
+#        make judgments about whether your system supports the use of this
+#        makefile.  The list is available in the ALL_PROGRAMS variable and,
+#        provided that you are using GNU make 3.80 or later (or you haven't
+#        renamed this file to something weird like "mylatexmakefile" and like
+#        invoking it with make -f) can be viewed using
+#
+#        make _all_programs
+#
+#        Additionally, the availability of these programs can be checked
+#        automatically for you by running
+#
+#        make _check_programs
+#
+#        The programs are categorized according to how important they are and
+#        what function they perform to help you decide which ones you really
+#        need.
+#
+#    Colorized Output:
+#        The output of commands is colorized to highlight things that are often
+#        important to developers.  This includes {underfull,overfull}
+#        {h,v}boxes, general LaTeX Errors, each stage of document building, and
+#        the number of pages in the final document.  The colors are obtained
+#        using 'tput', so colorization should work pretty well on any terminal.
+#
+#        The colors can be customized very simply by setting any of the
+#        LATEX_COLOR_<CONTEXT> variables in your environment (see above).
+#
+#    Predecessors to TeX Files:
+#        Given a target <target>, if no <target>.tex file exists but a
+#        corresponding script or predecessor file exists, then appropriate
+#        action will be taken to generate the tex file.
+#
+#        Currently supported script or predecessor languages are:
+#
+#        sh:     %.tex.sh
+#        perl:   %.tex.pl
+#        python: %.tex.py
+#
+#           Calls the script using the appropriate interpreter, assuming that
+#           its output is a .tex file.
+#
+#           The script is called thus:
+#
+#              <interpreter> <script file name> <target tex file>
+#
+#           and therefore sees exactly one parameter: the name of the .tex
+#           file that it is to create.
+#
+#           Why does this feature exist?  I ran into this while working on
+#           my paper dissertation.  I wrote a huge bash script that used a
+#           lot of sed to bring together existing papers in LaTeX.  It
+#           would have been nice had I had something like this to make my
+#           life easier, since as it stands I have to run the script and
+#           then build the document with make.  This feature provides hooks
+#           for complicated stuff that you may want to do, but that I have
+#           not considered.  It should work fine with included dependencies,
+#           too.
+#
+#           Scripts are run every time make is invoked.  Some trickery is
+#           employed to make sure that multiple restarts of make don't cause
+#           them to be run again.
+#
+#        reST: %.rst
+#
+#           Runs the reST to LaTeX converter to generate a .tex file
+#           If it finds a file names _rststyle_._include_.tex, uses it as
+#           the "stylesheet" option to rst2latex.
+#
+#           Note that this does not track sub-dependencies in rst files.  It
+#           assumes that the top-level rst file will change if you want a
+#           rebuild.
+#
+#    Dependencies:
+#
+#        In general, dependencies are extracted directly from LaTeX output on
+#        your document.  This includes
+#
+#        *    Bibliography information
+#        *    \include or \input files (honoring \includeonly, too)
+#        *    Graphics files inserted by the graphicx package
+#
+#        Where possible, all of these are built correctly and automatically.
+#        In the case of graphics files, these are generated from the following
+#        file types:
+#
+#        GraphViz:      .dot
+#        GNUPlot:       .gpi
+#        XFig:          .fig
+#        XMgrace:       .xvg
+#        SVG:           .svg
+#        PNG:           .png
+#        JPEG:          .jpg
+#        GZipped EPS:   .eps.gz
+#
+#        If the file exists as a .eps already, it is merely used (and will not
+#        be deleted by 'clean'!).
+#
+#        LaTeX and BibTeX are invoked correctly and the "Rerun to get
+#        cross-references right" warning is heeded a reasonable number of
+#        times.  In my experience this is enough for even the most troublesome
+#        documents, but it can be easily changed (if LaTeX has to be run after
+#        BibTeX more than three times, it is likely that something is moving
+#        back and forth between pages, and no amount of LaTeXing will fix
+#        that).
+#
+#        \includeonly is honored by this system, so files that are not
+#        specified there will not trigger a rebuild when changed.
+#
+#    Beamer:
+#        A special TeX source comment is recognized by this makefile (only when
+#        BUILD_STRATEGY=latex, since this invokes psnup):
+#
+#        %%[[:space:]]*BEAMER[[:space:]]*LARGE
+#
+#        The presence of this comment forces the output of dvips through psnup
+#        to enlarge beamer slides to take up an entire letter-sized page.  This
+#        is particularly useful when printing transparencies or paper versions
+#        of the slides.  For some reason landscape orientation doesn't appear
+#        to work, though.

+#        you.  Besides being unnecessary and potentially harmful, including the
+#        terminal definition in the .gpi file makes it harder for you, the one
+#        writing the document, to preview your graphics, e.g., with
+#
+#           gnuplot -persist myfile.gpi
+#
+#        so don't do specify a terminal or an output file in your .gpi files.
+#
+#        When building a gpi file into an eps file, there are several features
+#        available to the document designer:
+#
+#        Global Header:
+#            The makefile searches for the files in the variable GNUPLOT_GLOBAL
+#            in order:
+#
+#            ($(GNUPLOT_GLOBAL))
+#
+#            Only the first found is used.  All .gpi files in the directory are
+#            treated as though the contents of GNUPLOT_GLOBAL were directly
+#            included at the top of the file.
+#
+#            NOTE: This includes special comments! (see below)
+#
+#        Font Size:
+#            A special comment in a .gpi file (or a globally included file) of
+#            the form
+#
+#            ## FONTSIZE=<number>
+#
+#            will change the font size of the GPI output.  If font size is
+#            specified in both the global file and the GPI file, the
+#            specification in the individual GPI file is used.
+#
+#        Grayscale Output:
+#            GNUplot files also support a special comment to force them to be
+#            output in grayscale *no matter what*:
+#
+#            ## GRAY
+#
+#            This is not generally advisable, since you can always create a
+#            grayscale document using the forms mentioned above.  But, if your
+#            plot simply must be grayscale even in a document that allows
+#            colors, this is how you do it.
+#
+#    XFig Graphics:
+#            No special handling is done with XFig, except when a global
+#            grayscale method is used, e.g.
+#
+#                make GRAY=1 document
+#
+#            In these cases the .eps files is created using the -N switch to
+#            fig2dev to turn off color output.  (Only works with eps, not pstex
+#            output)
+#
+#    GraphVis Graphics:
+#            Color settings are simply ignored here.  The 'dot' program is used
+#            to transform a .dot file into a .eps file.
+#
+#            If you want, you can use the dot2tex program to convert dot files
+#            to tex graphics.  The default is to just call dot2tex with no
+#            arguments, but you can change the DOT2TEX definition to include
+#            options as needed (in your Makefile.ini).
+#
+#            Note that, as with pstex, the makefile cannot use latex's own
+#            output to discover all missing dot_t (output) files, since anytime
+#            TeX includes TeX, it has to bail when it can't find the include
+#            file.  It can therefore only stop on the first missing file it
+#            discovers, and we can't get a large list of them out easily.
+#
+#            So, the makefile errors out if it's missing an included dot_t
+#            file, then prompts the user to run this command manually:
+#
+#                make all-dot2tex
+#
+#    GZipped EPS Graphics:
+#
+#        A .eps.gz file is sometimes a nice thing to have.  EPS files can get
+#        very large, especially when created from bitmaps (don't do this if you
+#        don't have to).  This makefile will unzip them (not in place) to
+#        create the appropriate EPS file.

+\section{Configuration of the Datacage}
+
+\subsection{Tasks and Recommendation types of the datacage}
+
+The datacage serves two purposes.
+It handles automatic 'recommendations', which are instructions
+sent by the client to add newly created artifacts to the collection.
+From a user perspective, these artifacts mainly represent curves or data
+points in the resulting diagrams.
+The second task is to let the user add already existing artifacts (i.e.
+previous calculations) or new artifacts with access to related data.
+
+Irrelevant of the type of elements (recommendations or user picked data) the
+datacage can iterate over possible artifacts by accessing its own database.
+Thus, to create a list of matching entries, database queries are used.
+
+\subsection{Structure of the datacage configuration file meta-data.conf}
+
+The datacages behaviour is defined in the file conf/meta-data.xml .
+
+In meta-data.xml, database queries are defined as \verb!<dc:statement>! elements,
+for example
+\begin{lstlisting}
+                <dc:statement>
+                  SELECT id          AS prot_id,
+                         description AS prot_description
+                  FROM wsts WHERE kind = 1 AND river_id = ${river_id}
+                </dc:statement>
+\end{lstlisting}
+
+As can be seen from the example, the datacage configuration file can maintain
+its own stack of variables (\${river\_id} in above example).
+
+The database query will usually deliver one or many results, over which is
+iterated using the \verb!<dc:elements>! elements.
+
+Information from this results can be used for two goals.
+It can be taken as output, in which
+case the client will either request the creation of these artifacts (considering
+recommendations), or shown by the client in a the 'datacage widget',
+the graphical representation of data which can be added in the current
+context.  The later is seen when the user clicks on the Datacage button in
+a diagram.
+Or information can be used to feed a second (or third...) database query.
+Following above example:
+
+\begin{lstlisting}
+                <dc:statement>
+                  SELECT id          AS prot_id,
+                         description AS prot_description
+                  FROM wsts WHERE kind = 1 AND river_id = ${river_id}
+                </dc:statement>
+                <dc:elements>
+                  <additional>
+                    <dc:attribute name="name" value="${prot_description}"/>
+                    <dc:context>
+                      <dc:statement>
+                        SELECT id       AS prot_column_id,
+                               name     AS prot_column_name,
+                               position AS prot_rel_pos
+                        FROM wst_columns WHERE wst_id = ${prot_id}
+                        ORDER by position
+                      </dc:statement>
+                      <!-- ... -->
+\end{lstlisting}
+
+In both cases, an \verb!<dc:elements>! element makes database queries available.
+Also
+note how the variables are defined in the first query and reused in the second
+query (\$\{prot\_it\}).
+
+Any alement not prefixed with "dc" represents a (sub-) node in the resulting
+tree.  The client will display these nodes and maybe subnodes in the datacage
+widget - \verb!<additional>! in above example.  The elements name is translated by
+the client.
+
+While iterating the final results, \verb!<dc:attributes>! have to be specified
+to define how the artifact is to be created.
+
+\begin{lstlisting}
+                      <dc:elements>
+                        <column>
+                          <dc:attribute name="name" value="${prot_column_name}"/>
+                          <dc:attribute name="ids" value="additionals-wstv-${prot_rel_pos}-${prot_id}"/>
+                          <dc:attribute name="factory" value="staticwkms"/>
+                        </column>
+                      </dc:elements>
+\end{lstlisting}
+
+The "name" attribute is what is to be displayed in the client, the "ids" are given
+to the server and pass important information about the chosen data.
+The "factory" is chosen according to the type of data displayed.
+
+So far, three other elements have not yet been mentioned: \verb!<dc:comment>!,
+\verb!<dc:if>! and the \verb!<dc:when><dc:otherwise>! structure.
+\verb!<dc:comment>! is an element to allow comments.  Choose these over standard
+\verb=<!-- -->= xml comments, because they are not transferred to the client.
+\verb!<dc:if>! and \verb!<dc:when>! allow control (rather: definition) flow within
+the configuration and work in analogy to the XSL-elements \verb!<xsl:if>!
+and \verb!<xsl:when>!.
+
+When dealing with the behaviour specification of the datacage, multiple
+interpretations for the term "context" are possible.
+A \verb!<dc:context>! element essentially means a database binding.  Thus each
+query (\verb!<dc:statement>!) needs to be nested in its own context.
+Furthermore, two types of databases with own bindings exist:
+The "system" (default for \verb!<dc:context>!, \verb!<dc:context connection="system">!)
+context allows queries related to the backend database with existing
+data (e.g. measurements).
+The "user" context (\verb!<dc:context connection="user">!) allows queries against
+the database which stores information about already existing artifacts and
+calculations.
+
+Another connotation for the term "context" is the situation from which
+the datacage is queried.  The standard case is a from the datacage widget.
+When the user opens the datacage from the graphical client, this is done
+from one of possible multiple diagrams.
+When the datacage is queried, it gets as an argument the "out" of
+the current artifact.  The out corresponds to the diagram type.
+
+For example the inner block of
+
+\begin{lstlisting}
+          <dc:if test="dc:contains($artifact-outs, 'longitudinal_section')">
+              <longitudinal_section>
+                <dc:call-macro name="annotations"/>
+              </longitudinal_section>
+          </dc:if>
+\end{lstlisting}
+
+will only be executed if called from the datacage within a
+longitudinal\_section diagram.
+
+In the given example another concept of the datacage configuration is
+encountered: Macros.
+
+Macros help to avoid duplication of parts of the document.  As the datacage
+of some diagrams should include the same type of data, the same query should
+be executed in multiple situations.
+
+Therefore a macro can be defined, like in
+
+\begin{lstlisting}
+        <dc:macro name="basedata_4_heightmarks-wq">
+          <heightmarks>
+            <dc:context>
+              <dc:statement>
+                SELECT id          AS prot_id,
+                       description AS prot_description
+                FROM wsts WHERE kind = 4 AND river_id = ${river_id}
+              </dc:statement>
+              <dc:elements>
+              <!-- ... -->
+        </dc:macro>
+\end{lstlisting}
+
+and invoked from another location within the document, e.g. with
+
+\begin{lstlisting}
+
+                <dc:call-macro name="basedata_4_heightmarks"/>
+\end{lstlisting}
+.

+This document describes how the datacage configuration works, from a user
+perspective.  Some rather technical details are omitted and mechanisms
+simplified.
+
+The datacages behaviour is defined in the file conf/meta-data.xml .
+
+The datacage serves two purposes.
+It handles automatic 'recommendations', which are instructions
+sent by the client to add newly created artifacts to the collection.
+From a user perspective, these artifacts mainly represent curves or data
+points in the resulting diagrams.
+The second task is to let the user add already existing artifacts (i.e.
+previous calculations) or new artifacts with access to related data.
+
+Irrelevant of the type of elements (recommendations or user picked data) the
+datacage can iterate over possible artifacts by accessing its own database.
+Thus, to create a list of matching entries, database queries are used.
+
+In meta-data.xml, database queries are defined as <dc:statement> elements,
+for example
+                <dc:statement>
+                  SELECT id          AS prot_id,
+                         description AS prot_description
+                  FROM wsts WHERE kind = 1 AND river_id = ${river_id}
+                </dc:statement>
+
+As can be seen from the example, the datacage configuration file can maintain
+its own stack of variables (${river_id} in above example).
+
+The database query will usually deliver one or many results, over which is
+iterated using the <dc:elements> elements.
+
+Information from this results can be used for two goals.
+It can be taken as output, in which
+case the client will either request the creation of these artifacts (considering
+recommendations), or shown by the client in a the 'datacage widget',
+the graphical representation of data which can be added in the current
+context.  The later is seen when the user clicks on the Datacage button in
+a diagram.
+Or information can be used to feed a second (or third...) database query.
+Following above example:
+
+                <dc:statement>
+                  SELECT id          AS prot_id,
+                         description AS prot_description
+                  FROM wsts WHERE kind = 1 AND river_id = ${river_id}
+                </dc:statement>
+                <dc:elements>
+                  <additional>
+                    <dc:attribute name="name" value="${prot_description}"/>
+                    <dc:context>
+                      <dc:statement>
+                        SELECT id       AS prot_column_id,
+                               name     AS prot_column_name,
+                               position AS prot_rel_pos
+                        FROM wst_columns WHERE wst_id = ${prot_id}
+                        ORDER by position
+                      </dc:statement>
+                      <!-- ... -->
+
+In both cases, an <dc:elements> element makes database queries available.
+Also
+note how the variables are defined in the first query and reused in the second
+query (${prot_it}).
+
+Any alement not prefixed with "dc" represents a (sub-) node in the resulting
+tree.  The client will display these nodes and maybe subnodes in the datacage
+widget - <additional> in above example.  The elements name is translated by
+the client.
+
+While iterating the final results, <dc:attributes> have to be specified
+to define how the artifact is to be created.
+
+                      <dc:elements>
+                        <column>
+                          <dc:attribute name="name" value="${prot_column_name}"/>
+                          <dc:attribute name="ids" value="additionals-wstv-${prot_rel_pos}-${prot_id}"/>
+                          <dc:attribute name="factory" value="staticwkms"/>
+                        </column>
+                      </dc:elements>
+
+The "name" attribute is what is to be displayed in the client, the "ids" are given
+to the server and pass important information about the chosen data.
+The "factory" is chosen according to the type of data displayed.
+
+So far, three other elements have not yet been mentioned: <dc:comment>,
+<dc:if> and the <dc:when><dc:otherwise> structure.
+<dc:comment> is an element to allow comments.  Choose these over standard
+<!-- --> xml comments, because they are not transferred to the client.
+<dc:if> and <dc:when> allow control (rather: definition) flow within
+the configuration and work in analogy to the XSL-elements <xsl:if>
+and <xsl:when>.
+
+When dealing with the behaviour specification of the datacage, multiple
+interpretations for the term "context" are possible.
+A <dc:context> element essentially means a database binding.  Thus each
+query (<dc:statement>) needs to be nested in its own context.
+Furthermore, two types of databases with own bindings exist:
+The "system" (default for <dc:context>, <dc:context connection="system">)
+context allows queries related to the backend database with existing
+data (e.g. measurements).
+The "user" context (<dc:context connection="user">) allows queries against
+the database which stores information about already existing artifacts and
+calculations.
+
+Another connotation for the term "context" is the situation from which
+the datacage is queried.  The standard case is a from the datacage widget.
+When the user opens the datacage from the graphical client, this is done
+from one of possible multiple diagrams.
+When the datacage is queried, it gets as an argument the "out" of
+the current artifact.  The out corresponds to the diagram type.
+
+For example the inner block of
+
+          <dc:if test="dc:contains($artifact-outs, 'longitudinal_section')">
+              <longitudinal_section>
+                <dc:call-macro name="annotations"/>
+              </longitudinal_section>
+          </dc:if>
+
+will only be executed if called from the datacage within a
+longitudinal_section diagram.
+
+In the given example another concept of the datacage configuration is
+encountered: Macros.
+
+Macros help to avoid duplication of parts of the document.  As the datacage
+of some diagrams should include the same type of data, the same query should
+be executed in multiple situations.
+
+Therefore a macro can be defined, like in
+
+        <dc:macro name="basedata_4_heightmarks-wq">
+          <heightmarks>
+            <dc:context>
+              <dc:statement>
+                SELECT id          AS prot_id,
+                       description AS prot_description
+                FROM wsts WHERE kind = 4 AND river_id = ${river_id}
+              </dc:statement>
+              <dc:elements>
+              <!-- ... -->
+        </dc:macro>
+

+
+2011-06-26	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/model/River.java:
+	  Added a method maxOverlap to determine the gauge which has
+	  the max common length to a given interval. This is for
+	  numerical stability in slightly overlapping gauge ranges.
+
+2011-06-26	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/model/River.java: When

+
+	* src/main/java/de/intevation/flys/model/River.java:
+	  Added method to find gauge by its name.
+
+2011-06-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* doc/annotation-types.xml: Fixed some rules.
+
+	* src/main/java/de/intevation/flys/importer/Importer.java,
+	  src/main/java/de/intevation/flys/importer/InfoGewParser.java,
+	  src/main/java/de/intevation/flys/importer/ImportRiver.java:
+	  Call the right constructors now.
+
+	* src/main/java/de/intevation/flys/importer/ImportAnnotationType.java:
+	  Added getter/setter for name property.
+
+	* src/main/java/de/intevation/flys/importer/AnnotationsParser.java:
+	  Print duplicated at WARN level not as DEBUG.
+
+	* src/main/java/de/intevation/flys/importer/AnnotationClassifier.java:
+	  Fixed XPath expression to build the internal lookup structures
+	  correctly.
+
+2011-06-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	Added classification of annotation types. Needs testing!
+
+	* doc/annotation-types.xml: New. Rules to classify the different
+	  types of annotations. The classification works like this:
+
+	  There are unique types like 'Bruecke', 'Pegel' and so on.
+	  They are defined in the /annotation/type section and
+	  identified by their name. One of the types can be set 
+	  as the default type if no rule applies.
+
+	  In the /annotation/pattern section are two types of pattern.
+
+	  1 - file pattern: If a KM file is opened its filename is
+	      matched against the regular expressions of these
+		  patterns. If a match is found the corresponding type
+		  is used as the default type in the open file.
+		  If no match is found the global default type is used
+		  as the default type.
+
+	  2 - line patterns: For each line of an open KM file these
+	      patterns are applied to find a match. If a match is
+		  found the corresponding type is used as the type of
+		  the annotation. If no match is found the default
+		  file default is assumed to be the right type. For
+		  the file default see 1.
+
+	* src/main/java/de/intevation/flys/importer/Importer.java:
+	  To activate the annotation type classification set
+	  the system property
+
+	      'flys.backend.importer.annotation.types'
+
+	  to the path of a XML looking like the annotation-types.xml
+	  file. If the system property is not set no classification
+	  is done.
+
+	* src/main/java/de/intevation/flys/importer/AnnotationClassifier.java:
+	  New. Implements the classification.
+	  
+	* src/main/java/de/intevation/flys/importer/AnnotationsParser.java,
+	  src/main/java/de/intevation/flys/importer/InfoGewParser.java,
+	  src/main/java/de/intevation/flys/importer/ImportRiver.java:
+	  Looped through the annotation type classification.

+
+2011-05-10	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* doc/schema/postgresql.sql: Added a column which tells

+2011-05-09	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/ValueKey.java:
+	  Add some unsharp comparison (eps = 1e-6) to avoid 
+	  numerical problems.
+
+	* src/main/java/de/intevation/flys/importer/IdValueKey.java:
+	  Removed. Not need any longer.
+
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:

+
+	* src/main/java/de/intevation/flys/importer/ImportWst.java,

+	  Flush more often. Hopefully this reduces hibernate sync
+	  problems?!
+
+2011-05-09	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  Fixed silly bug. Set flush mode back to auto because
+	  manual flushing causes some undetermined problems.
+
+2011-05-09	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  Do not load _all_ values from discharge tables and
+	  wst columns. This is extremly slow and will lead
+	  to OOM if more rivers are imported. Now only the
+	  last 20 columns und discharge tables are cached.
+
+	* src/main/java/de/intevation/flys/importer/ValueKey.java:
+	  New. Key for caching discharge table values and wst
+	  column values.
+
+	* src/main/java/de/intevation/flys/importer/IdValueKey.java:
+	  Fixed bug in equals().
+
+	* src/main/java/de/intevation/flys/importer/ImportWstColumn.java:
+	  Removed too eloquent debug output.
+
+2011-05-09	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/IdValueKey.java:
+	  Use BigDecimals as representation for the numeric components
+	  which prevents running into unique constraint problems
+	  caused by imprecision.
+
+	* src/main/java/de/intevation/flys/importer/ImportRange.java,
+	  src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  Ranges are now cached globally, too.
+
+	* src/main/java/de/intevation/flys/importer/ImportWstColumn.java:
+	  Improved logging.
+
+	* src/main/java/de/intevation/flys/importer/ImportDischargeTableValue.java:
+	  Removed superfluous imports.
+
+2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/StaFileParser.java:
+	  Only accept main value types 'Q', 'W', 'D' and 'T' by default.
+	  '-' is not handled any more because it causes too much constraint
+	  problems. You can overwrite the imported type with the
+	  system property flys.backend.main.value.types" (default "QWTD")
+	  
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  Set session flush mode to manual. Hopefully this improves the
+	  performance a bit.

+
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  New. Centralized caching in the thread local context. Importing
+	  the Elbe leads to OOM because the column values of the
+	  WST files where loaded separately for every file.

+
+2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* doc/schema/postgresql.sql: Dropped constraint which
+	  forces discharge tables to have a unique time interval
+	  for a given gauge and kind.
+
+	  There are AT files (historical Mosel/Perl/Perl/1967-1981.at
+	  and Mosel/Perl/1967-1981-1.at) which violate this
+	  constraint. Its a technical question to the customer
+	  how to handle these cases.
+
+	  To adjust existing databases:

+	    ALTER TABLE discharge_tables DROP CONSTRAINT discharge_tables_gauge_id_key;
+
+2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+

+	  Import the "HW-Schutzanlagen", too.
+
+2011-05-05	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	Make import of historical discharge tables work.

+	  Add convinience constructor with start and stop time.
+
+	* src/main/java/de/intevation/flys/importer/AtFileParser.java:
+	  Attach a time interval to a discharge table if we find one.
+
+	* src/main/java/de/intevation/flys/importer/ImportDischargeTable.java:
+	  Store the reference to the importer model of the

+          - determine the selected gauge(s) based on a kilometer range
+
+        * WSTs are able to determine their min/max Q range.

+          value tables.
+
+        * Added one-to-many relation Wst -> WstColumn
+
+        * Speedup of the importer by using an internal caching mechanism.

+FLYS3-Importer
+
+Der FLYS3-Importer dient dazu, hydrologische und morphologische
+Gewässerdaten aus dem Dateisystem in die FLYS3-Datenbank zu importieren.
+Das Werkzeug orientiert sich hierbei an der Dateihierachie,
+so wie sie auch von Desktop-FLYS ausgelesen wird.
+
+Als Startargument bekommt der Importer den Pfad zu einer
+GEW-Datei übergeben. 
+
+Wichtig für den Importer sind in dieser Datei
+die Zeilen, die mit "WSTDatei:" beginnen. In ihnen wird der 
+Pfad zu der zentralen WST-Datei des jeweiligen Gewässers angegeben.
+Alle anderen importierten Dateien werden in ihrer Lage relativ zur 
+Lage dieser Datei betrachtet.
+
+Das Verhalten des Importes kann mit sogenannten
+System-Properties gesteuert werden. Diese werden im
+Allgemeinen in der Form -Dkey=value angegeben.
+
+Will man z.B. mit dem Importer nur in simulierierten Import
+durchführen, dann kann dies über die Angabe von
+'-Dflys.backend.importer.dry.run=true' erfolgen.
+
+!!! Der Import geht wie Desktop-FLYS davon aus, dass die Dateien
+!!! Latin-1 encodiert vorliegen.
+
+Für den Importer stellt jeweils der Import eines Gewässers eine
+transaktionale Einheit dar. Wird der Import während eines Gewässers
+abgebrochen, werden alle Änderungen bzgl. dieses Gewässers zurück gerollt.
+
+Importierte Daten:
+
+Der Importer importiert folgende Datentypen:
+
+- Streckenfavoriten (*.km-Dateien)
+  Der Import kann mit '-Dflys.backend.importer.skip.annotations=true'
+  unterdrückt werden.
+
+  Zur Klassifikation von Streckenfavoriten kann mit
+  -Dflys.backend.importer.annotation.types=DATEI
+  der Pfad zu einer XML-Datei angegeben werden, in der über
+  Regeln festgelegt wird, wie diese geschehen soll.
+  Details hierzu im Anhang 'Klassifikation von Streckenfavoriten'.
+
+- Pegel, Stammdaten (*.glt, *.sta-Dateien):
+  Der Import kann mit '-Dflys.backend.importer.skip.gauges=true'
+  unterdrückt werden.
+  Die .glt-Datei, die neben der .wst-Datei liegt, wird zuerst
+  ausgelesen. Es werden nur *.sta-Datei von Pegeln geladen, die
+  in der .glt-Datei vermerkt sind.
+
+  Wenn "-Dflys.backend.sta.parse.gauge.numbers=true' wird versucht,
+  die offiziellen Pegelnummern aus den Stammdaten zu extrahieren.
+  !!! Dies ist mit Vorsicht zu behandeln, denn die meisten STA-Dateien
+  !!! Enthalten invalide Pegelnummern.
+
+  Die System-Property "flys.backend.main.value.types" kann einen
+  String mit gültigen Typen von Stammdaten enthalten. Vorbelegt
+  ist "QWTD". In der Praxis ist "QWD" eine sinnvolle Belegung.
+
+- Basis-Wasserstände (gewaesser.wst-Dateien):
+  Der Import kann mit '-Dflys.backend.importer.skip.wst=true'
+  unterdrückt werden.
+
+- Zusätzliche Längsschnitte (*.zus, *.wst-Dateien)
+  Der Import kann mit '-Dflys.backend.importer.skip.extra.wsts=true'
+  unterdrückt werden.
+  Es werden die *.zus- und *.wst-Dateien aus dem Verzeichnis
+  "../Zus.Längsschnitte" relativ zur gewaesser.wst-Datei betrachtet.
+
+- Fixierungen (*.wst-Dateien)
+  Der Import kann mit '-Dflys.backend.importer.skip.fixations=true'
+  unterdrückt werden.
+  Es werden die *.wst-Dateien aus dem Verzeichnis
+  "../Fixierungen" relativ zur gewaesser.wst-Datei betrachtet.
+
+- Amtliche Linien (*.wst-Dateien)
+  Der Import kann mit '-Dflys.backend.importer.skip.official.lines=true'
+  unterdrückt werden.
+  Es werden die "Amtl_Linien.wst"-Dateien aus dem Verzeichnis
+  "../Basisdaten" und "../Fixierungen" relativ zur gewaesser.wst-Datei betrachtet.
+
+- Profilspuren (*.prf-Dateien)
+  Der Import kann mit '-Dflys.backend.importer.skip.prfs=true'
+  unterdrückt werden.
+  Es werden rekursiv alle *.prf-Dateien aus "../../.." relativ
+  zur gewaesser.wst-Datei betrachtet. Vor dem Import werden
+  mithilfe eines Längen- und eines MD5-Summen-Vergleichs
+  inhaltliche Duplikate ausgeschlossen.
+
+- Hydraulische Kennzahlen (*.hyk)
+  Der Import kann mit '-Dflys.backend.importer.skip.hyks=true'
+  unterdrückt werden.
+  Es werden rekursiv alle *.hyk-Dateien aus "../../.." relativ
+  zur gewaesser.wst-Datei betrachtet. Vor dem Import werden
+  mithilfe eines Längen- und eines MD5-Summen-Vergleichs
+  inhaltliche Duplikate ausgeschlossen.
+
+- Hochwassermarken (*.zus, *.wst)
+  Der Import kann mit '-Dflys.backend.importer.skip.flood.water=true'
+  unterdrückt werden.
+  Es werden die *.zus- und *.wst-Dateien aus dem Verzeichnis
+  "../HW-Marken" relativ zur gewaesser.wst-Datei betrachtet.
+
+- Hochwasserschutzanlagen (*.zus)
+  Der Import kann mit '-Dflys.backend.importer.skip.flood.protection=true'
+  unterdrückt werden.
+  Es werden die *.zus- und *.wst-Dateien aus dem Verzeichnis
+  "../HW-Schutzanlagen" relativ zur gewaesser.wst-Datei betrachtet.
+
+  TODO INGO:
+
+  flys.backend.importer.skip.bed.height.single
+  flys.backend.importer.skip.bed.height.epoch
+  flys.backend.importer.skip.sediment.density
+  flys.backend.importer.skip.morphological.width

+  flys.backend.importer.skip.waterlevels
+  flys.backend.importer.skip.waterlevel.differences
+  flys.backend.importer.skip.sq.relation
+
+Für die Verbindung zur Datenbank ist es nötig, dem Import
+die Verbindungsdaten zu übergeben. Dies geschieht ebenfalls
+über System-Properties:
+
+  -Dflys.backend.user=NUTZER
+   Datenbanknutzer
+
+  -Dflys.backend.password=PASSWORT
+   Datenbankpasswort
+
+  -Dflys.backend.url=URL
+   URL zur Datenbank. Typische wäre im Fall einer Oracle-XE-Edition z.B.:
+   jdbc:oracle:thin:@//RECHNER:PORT/XE
+   mit RECHNER Name des Servers, auf dem die Datenbank läuft
+   und PORT der Port auf dem die Datenbank konkret zu erreichen ist.
+   Weitere Details unter http://www.orafaq.com/wiki/JDBC
+
+ -Dflys.backend.driver=TREIBER
+  mit TREIBER dem Namen des JDBC-Treibers, der es erlaubt
+  das Protokoll der Datenbank zu sprechen. Im Falle
+  einer Oracle XE wäre dies z.B.:
+  oracle.jdbc.OracleDriver
+
+ -Dflys.backend.dialect=DIALECT
+  mit DIALECT dem Hibernate-Dialekt, den die Datenbank versteht.
+  Im Falle eine Oracle-XE wäre dies z.B.:
+  org.hibernate.dialect.OracleDialect
+
+
+Hinweise zum Betrieb:
+---------------------
+
+    Der Speicherverbrauch des Importers ist sehr hoch. Es ist empfehlenswert,
+    der JVM mindestens 8GiB Hauptspeicher zuzuordnen: '-Xmx8192m'
+    Besonders speicherintensiv ist der Import der HYKs und der PRFs.
+    Hier ist es unter Umständen empfehlenswert, diese in zwei oder drei
+    Schritten zu importieren. Zuerst die sonstigen hydrologischen Daten
+    (hierbei mit flys.backend.importer.skip.hyks=true und flys.backend.importer.skip.prfs
+    den Import der HYKs und PRFs verhindern). Dann die HYKs (mit flys.backend.importer.skip.*
+    der anderen Daten) und im finalen Schritt dann die PRFs.
+
+Anhang 'Klassifikation von Streckenfavoriten'
+---------------------------------------------
+Streckenfavoriten werden aus KM-Dateien importiert. Um die einzelnen Einträge
+eine Kategorie (Brücken, Pegel, etc.) zuzuordnen, kann eine XML angegeben werden,
+in der Regeln für diese Klassifikation definiert werden. Schematisch gliedert
+sich diese Datei in die zwei Bereiche 'types' und 'patterns':
+
+<annotation>
+    <types> ...  </types>
+    <patterns> ...  </patterns>
+</annotation>
+
+In der Sektion 'types' werden die Kategorien vereinbart, in die
+klassifiziert werden sollen. Die geschieht mit einzelnen
+
+  <type name="Pegel"/>
+  <type name="Brücke"/>
+  ...
+  <type name="Sonstige" default="true"/>
+
+Das Attribut 'default' kann einmal vergeben werden und
+besagt, dass diese Kategorie gewählt werden soll, wenn
+keine andere Kategorie zugeordnet werden kann.
+
+In der Sektion 'patterns' werden dann die Regel
+definiert, die einzelne Einträge den definierten Kategorien
+zuordnet. Hierfür können zwei Arten von Definitionen
+angegeben werden:
+
+  <file pattern="^Brücken$" type="Brücke"/>
+
+oder
+
+  <line pattern="^Brücke[:\s].*$" type="Brücke"/>
+
+Die erste Variante bestimmt die Kategorie, die pro KM-Datei
+gelten soll. 'pattern' ist hierbei ein regulärer Ausdruck,
+der auf den Dateinamen angewandt wird. Passt der Name
+der Datei auf den regulären Ausdruck, wird 'type' als
+Vorgabe angenommen. Treffen mehrere <file>-Regeln zu,
+wird der erste Treffer angewandt. Findet keine der <file>-Regeln
+Anwendung, wird die Kategorie ausgewählt, die in der <types>-Section
+das Attribut 'default' gesetzt hat.
+
+Die zweite Regel-Variante <line> wird auf jeden Eintrag
+innerhalb einer KM-Datei auf den Bezeichner der Streckenfavoriten
+angewandt. Als Muster dient auch hier ein regulärer Ausdruck,
+der über das Attribut 'pattern' definiert wird. Die Kategorie
+wird in Trefferfall über das Attribut 'type' bestimmt. Treffen
+mehrere Regeln zu, wird die Kategorie gewählt, die zum ersten
+Treffer gehört. Trifft keine Regel zu wird der Eintrag der
+Kategorie zugeteilt, die für die beinhaltende Datei als Vorgabe
+gilt.

+# KNOWN ISSUES:
+#	* The following occurs:
+#		file with: \usepackage{named}\bibliographystyle{named}
+#		Compile
+#		change to: \usepackage{apalike}\bibliographystyle{apalike}
+#		Compile again -- BARF!
+#
+#		The workaround: make clean-nographics; make
+#
+#		Note that we may not be able to fix this.  LaTeX itself barfs
+#		on this, not the makefile.  The very first invocation of LaTeX
+#		(when something like this has happened) reads the existing .aux
+#		file and discovers invalid commands like \citeauthoryear that
+#		are only valid in the package that was just removed.  It then
+#		tries to parse them and explodes.  It's not at all clear to me
+#		how to fix this.  I tried removing the .aux files on the first
+#		run of LaTeX, but that necessarily requires more subsequent
+#		rebuilds on common edits.  There does not appear to be a
+#		graceful solution to this issue.
+#
+# CHANGES:
+# Chris Monson (2010-04-08):
+# 	* Bumped version to 2.2.0-rc1
+# 	* Added back in the rst_style_file stuff that got broken when switching
+# 		rst -> tex to use the script mechanism
+# Chris Monson (2010-03-23):
+#	* Bumped version to 2.2.0-beta8
+#	* Work on issue 76: bad backtick escape for some sed versions, failure
+#		to clear out the hold buffer when outputting MISSING comment.
+#		- Backed out 2>&1 to &> (doesn't work in sh)
+#		- Backed out using . to source variables
+# Chris Monson (2010-03-22):
+# 	* Bumped version to 2.2.0-beta7
+# 	* Issue 72: Fix latex/bibtex invocation order for annotated bib styles
+# 	* Fixed informational output to reflect which LaTeX run we're on
+# 	* Fixed graphic detection to include graphics that are already there in
+# 		.d files
+# 	* Tightened up the .d file output to only make .d depend on graphic
+# 		*source* files.  This means that building foo.d no longer
+# 		builds all of the graphics files on which foo.tex depends.
+# 		Had to use .SECONDEXPANSION trickery to make it work.
+# 	* Changed get-graphics to only accept a stem.
+# 	* Fixed build-once logic for scripted .tex to work better
+# 	* Made get-inputs sed script more maintainable.
+# 	* Moved Makefile.ini import up higher.
+# 	* Changed bare stems to not recursively invoke make
+# 	* Updated diff output to be more silent everywhere
+# 	* Added a MISSING comment to the .d file if stuff isn't found - forces
+# 		removal of .1st.make file, which often forces it to try again.
+# 	* Fixed broken graphics-target function
+# 	* Added sleep to .d file generation when stuff is missing - if it
+# 		builds too fast, make doesn't realize it needs to be reloaded,
+# 		and thus never discovers some deeper dependencies (especially
+# 		evident when graphics are included from scripted include
+# 		files).
+# Chris Monson (2010-03-17):
+# 	* Bumped version to 2.2.0-beta6
+# 	* Fixed bareword builds to actually work (requires static patterns)
+# 	* Fixed colorization to work with new paragraph stuff
+# Chris Monson (2010-03-17):
+# 	* Bumped version to 2.2.0-beta5
+# 	* Fixed graphic detection to be much more focused - splits log file
+# 		into paragraphs before doing pattern matching.
+# 	* Fixed make foo to work properly (recursively calls make foo.pdf)
+# 	* Fixed gpi -> pdf generation to not waste time building .eps *after*
+# 		the pdf already exists.
+# 	* Changed log copies to include MAKE_RESTARTS as part of the name.
+# 	* Fixed missing include file detection (also makes use of the paragraph
+# 		stuff) to detect missing scripted include files.
+# Chris Monson (2010-03-16):
+# 	* Bumped version to 2.2.0-beta4
+# 	* issue 70: .pdf not moved out of the way properly on first
+# 		compilation, resulting in early error detection failure.
+# 	* issue 74: fixed broken error on missing .aux files: the
+# 		implementation was masking real errors.
+# Chris Monson (2010-03-15):
+# 	* Bumped version to 2.2.0-beta3
+# 	* issue 71: Made the tput dependency optional
+# 	* issue 73: Made .tex targets not pull in .d files (building them from
+# 		scripts should not require a .d)
+# 	* issue 74: Output a much saner error when a .aux file is not produced
+# 		(e.g., when you are typing "make" without arguments in a
+# 		directory with included .tex files that are not named with
+# 		._include_.)
+# Chris Monson (2010-03-11):
+# 	* Bumped version to 2.2.0-beta2
+# 	* Fixed clean-graphics to get rid of intermediate .eps files that may
+# 		be hanging around
+# 	* Added an automatic setting to use eps terminals in pdflatex mode for
+# 		gnuplot if it doesn't understand pdf.
+# 	* issue 66: Removed grayscale generation via magic suffix.  Grayscale
+# 		generation is now only available via GRAY=1
+# 	* issue 68: Added explicit handling of LC_ALL for locale-aware tools
+# 		like "sort"
+# Chris Monson (2010-03-10):
+# 	* Bumped version to 2.2.0-beta1
+# 	* Fixed success message to handle output message in different places
+# 	* Added name of produced file to success message
+# Chris Monson (2010-03-10):
+# 	* Bumped version to 2.2.0-alpha3
+# 	* Added meaningful error message for wrong hyperref options
+# 	* Added meaningful error message for incorrect graphics extensions
+# Chris Monson (2010-03-09):
+# 	* Bumped version to 2.2.0-alpha2
+# 	* Updated graphics handling (gnuplot and fig generate pdf natively)
+# 	* Changed xmgrace to output monochrome natively
+# Chris Monson (2010-03-09):
+# 	* Bumped version to 2.2.0-alpha1 - major change!
+# 	* Support pdflatex natively and by default (issue 6 - a long time coming)
+# 	* Add ability to have a single $HOME/.latex-makefile/Makefile.ini for
+# 		all invocations
+# 	* Reworked graphic inclusion detection so that extensions need not be
+# 		specified for either build strategy (e.g.,
+# 		\includegraphics{test1.eps} -> \includegrahpics{test1})
+# 	* Changed log format to include filenames and line numbers
+# Chris Monson (2010-02-04):
+# 	* Bumped version to 2.1.43
+# 	* All of the following are for issue 63 (thanks to mojoh81):
+# 	* Added documentation about fixing Makefile.ini default target
+# 	* Added perl and python script targets
+# 	* Fixed run logic to allow included .tex files to be scripted (the
+# 		run-again logic now detects missing .tex files, and the MV
+# 		command has been switched out for a command that only invokes
+# 		MV if the files exist)
+# 	* Changed scripted generation to only run once per make invocation
+# 	* Added dependency on expr
+# Chris Monson (2010-01-19):
+# 	* Bumped version to 2.1.42
+# 	* issue 62: Added .brf extension to cleanable files (backrefs)
+# Chris Monson (2010-01-07):
+# 	* Bumped version to 2.1.41

+# 	* Fixed typo in changelist
+# 	* Issue 52: added jpg->eps conversion (thanks to brubakee)

+# Chris Monson (2009-03-27):

+# Chris Monson (2008-05-21):
+# 	* Bumped version to 2.1.20
+# 	* Added manual pstex compilation support (run make all-pstex first)
+# 	* Removed all automatic pstex support.  It was totally breaking

+# 	* Bumped version to 2.1.15
+# 	* issue 18: Favors binary echo over builtin, as binary understands -n
+# 	* issue 16: Fixed handling of missing pstex_t files in the log
+# 	* issue 9: Added .SECONDARY target for .pstex files
+# Chris Monson (2008-03-21):
+# 	* Bumped version to 2.1.14

+# 		missed.
+# Chris Monson (2008-03-20):
+# 	* Bumped version to 2.1.13

+# 	* Bumped version to 2.1.9
+# 	* Fixed documentation and dependency graph for pstex files

+# 	* Bumped version to 2.1.8
+# 	* Added basic pstex_t support for fig files (Issue 9 by favonia)
+# 		I still suggest that psfrag be used instead.
+# Chris Monson (2007-10-16):
+# 	* Bumped version to 2.1.7
+# 	* Removed todo item: allow other comment directives for rst conversion
+# 	* Added ability to use global rst style file _rststyle_._include_.tex
+# 	* Added help text to that effect

+# 	* Bumped version to 2.0b3
+# 	* Top level includes now fail if there is no rule to build them

+# 	* Grayscale handling has been completed
+# 	* Changed _include_stems target to _includes target.
+# 	* Fixed _includes target to be useful by itself.
+# 	* Removed the ability to specify clean and build targets at once

+# 	* Fixed included scripts so that they are added to the dep files
+# 	* Fixed so that graphics includes don't happen if they aren't for gpi
+# 	* Fixed dot output to allow grayscale.
+# Chris Monson (2006-04-05):
+#	* Bumped version to 2.0b2

+#	* Fixed diff output to...not output.
+#	* Fixed rerun bug -- detect not only when preceded with LaTeX Warning
+#	* Sped up gpi plotting
+#	* Added error handling and colorized output for gpi failure
+#	* Documented color changing stuff.
+#	* Now sort the flattened aux file to avoid false recompilation needs
+#	* Added clean-nographics target
+#	* Don't remove self.dvi file if self.aux is missing in the log
+#	* Clarified some code.  Did some very minor adjusting.
+# Chris Monson (2006-04-03):
+#	* Bumped version to 2.0a7

+#	* Added the dependency graph directly into the makefile.
+#	* Changed flatten-aux to remove \@writefile \relax \newlabel, etc.
+#	* Undid pipe changes with sed usage (BSD sed doesn't know -f-).

+#	* Fixed an error in colorization that made unnecessary errors appear
+#	* Added view targets.
+#	* Updated help text.
+#	* Augmented cookies so that .aux can trigger .bbl and .dvi rebuilds
+#	* Added more informative error handling for dvips and ps2pdf
+# Chris Monson (2006-04-02):
+#	* Bumped version to 2.0a6

+#	* Removed special shell quote escape variables
+#	* Moved includes to a more prominent location
+#	* Fixed .inputs.make to not contain .aux files
+#	* Fixed embedding to use a file instead of always grepping.
+#	* Added *.make.temp to the list of cleanable files
+#	* Fixed Ruby.  It should now be supported properly.
+#	* Now differentiate between all, default, and buildable files.
+#	* Fixed to bail out on serious errors.
+#	* Revised the handling of includable files.  Still working on it.
+# Chris Monson (2006-03-31):
+#	* Bumped version to 2.0a5
+#	* Fixed a bug with LaTeX error detection (there can be spaces)
+#	* Added .bbl support, simplifying everything and making it more correct

+#	* Bumped version to 2.0a4
+#	* Fixed a bug with very long graphics file names
+#	* Added a todo entry for epsfig support
+#	* Fixed a bug paper size bug: sometimes more than one entry appears
+#	* Fixed DVI build echoing to display the number instead of process ID
+#	* DVI files are now removed on first invocation if ANY file is missing
+#	* Added a simple grayscale approach: if a file ends with -gray.gpi, it
+#		is created from the corresponding .gpi file with a special
+#		comment ##GRAY in its header, which causes coloring to be
+#		turned off.
+#	* Fixed a bug in the handling of .tex.sh files.  For some reason I had
+#		neglected to define file stems for scripted output.
+#	* Removed a trailing ; from the %.graphics dependencies
+#	* Added dvips embedding (I think it works, anyway)
+# Chris Monson (2006-03-29):
+#	* Bumped version to 2.0a3
+#	* Fixed error in make 3.79 with MAKEFILE_LIST usage
+#	* Added the presumed filename to the _version output
+#	* Added a vim macro for converting sed scripts to make commands
+#	* Added gpi dependency support (plotting external files and loading gpi)
+#	* Allow .gpi files to be ignored if called .include.gpi or .nobuild.gpi
+#	* Fixed sed invocations where \+ was used.  BSD sed uses \{1,\}.
+# Chris Monson (2006-03-28):
+#	* Bumped version to 2.0a2
+#	* Added SHELL_DEBUG and VERBOSE options
+#	* Changed the default shell back to /bin/sh (unset, in other words)
+#	* Moved .PHONY declarations closer to their targets
+#	* Moved help text into its own define block to obtain better formatting
+#	* Removed need for double-entry when adding a new program invocation
+#	* Moved .SECONDARY declaration closer to its relevant occurrence
+#	* Commented things more heavily
+#	* Added help text about setting terminal and output in gnuplot
+#	* Created more fine-grained clean targets
+#	* Added a %.graphics target that generates all of %'s graphics
+#	* Killed backward-compatible graphics generation (e.g., eps.gpi=gpi.eps)
+#	* For now, we're just GPL 2, not 3.  Maybe it will change later
+#	* Made the version and svninfo into variables
+# Chris Monson (2006-03-27):
+#	* Bumped version to 2.0a1
+#	* Huge, sweeping changes -- automatic dependencies

+# BSD SED NOTES
+#
+# BSD SED is not very nice compared to GNU sed, but it is the most

+# it or require people to install GNU sed.  It seems like the GNU
+# requirement isn't too bad since this makefile is really a GNU makefile,
+# but apparently GNU sed is much less common than GNU make in general, so
+# I'm supporting it here.
+#
+# Sad experience has taught me the following about BSD sed:
+#
+# 	* \+ is not understood to mean \{1,\}
+# 	* \| is meaningless (does not branch)
+# 	* \n cannot be used as a substitution character
+# 	* ? does not mean \{0,1\}, but is literal
+# 	* a\ works, but only reliably for a single line if subsequent lines
+# 		have forward slashes in them (as is the case in postscript)
+#
+# For more info (on the Mac) you can consult
+#
+# man -M /usr/share/man re_format
+#
+# And look for the word "Obsolete" near the bottom.

+# 2) Ensure that the last line of the file gets appended to the hold buffer,

+# 3) When encountering a blank line (LaTeX output helpfully breaks output on

+# 	a) swap the hold buffer (containing the paragraph) into the pattern buffer (putting a blank line into the hold buffer),
+# 	b) remove the newline at the beginning (don't ask),
+# 	c) apply any colorizing substitutions necessary to ensure happiness.
+# 	d) get the newline out of the hold buffer and append it
+# 	e) profit! (print)

+# Hi = int(floor(6 * H)) mod 6

+# p = V(1-S)

+# Generate all of the information needed to get dependencies
+# As a side effect, this creates a .dvi or .pdf file (depending on the build
+# strategy).  We need to be sure to remove it if there are errors.  Errors can
+# take several forms and all of them are found within the log file:
+#	* There was a LaTeX error
+#	* A needed file was not found
+#	* Cross references need adjustment
+#
+# Behavior:
+#	This rule is responsible for generating the following:
+#	%.aux
+#	%.d
+#	%.aux.make
+#	%.(pdf|dvi).1st.make (the .pdf or .dvi output file, moved)

+#	Steps:
+#
+#	Run latex
+#	Move .pdf or .dvi somewhere else (make no judgements about success)
+#	Flatten the .aux file into another file
+#	Add source dependencies
+#	Add graphic dependencies
+#	Add bib dependencies
+#
+#	Create cookies for various suffixes that may represent files that
+#	need to be read by LaTeX in order for it to function properly.
+#
+#	Note that if some of the dependencies are discovered because they turn
+#	up missing in the log file, we really need the .d file to be reloaded.
+#	Adding a sleep command helps with this.  Otherwise make is extremely
+#	nondeterministic, sometimes working, sometimes not.

+# Generates a number of possible output files from a LaTeX document and its
+# various dependencies.  Handles .bib files, \include and \input, and .eps
+# graphics.  All dependencies are handled automatically by running LaTeX over
+# the source.
+#
+# USAGE:
+#
+#    make [GRAY=1] [VERBOSE=1] [SHELL_DEBUG=1] <target(s)>
+#
+# STANDARD OPTIONS:
+#    GRAY:
+#        Setting this variable forces all recompiled graphics to be grayscale.
+#        It is useful when creating a document for printing.  The default is
+#        to allow colors.  Note that it only changes graphics that need to be
+#        rebuilt!  It is usually a good idea to do a 'make clean' first.
+#
+#    VERBOSE:
+#        This turns off all @ prefixes for commands invoked by make.  Thus,
+#        you get to see all of the gory details of what is going on.
+#
+#    SHELL_DEBUG:
+#        This enables the -x option for sh, meaning that everything it does is
+#        echoed to stderr.  This is particularly useful for debugging
+#        what is going on in $$(shell ...) invocations.  One of my favorite
+#        debugging tricks is to do this:
+#
+#        make -d SHELL_DEBUG=1 VERBOSE=1 2>&1 | less
+#
+# STANDARD AUXILIARY FILES:
+#
+#      Makefile.ini
+#
+#          This file can contain variable declarations that override various
+#          aspects of the makefile.  For example, one might specify
+#
+#          neverclean := *.pdf *.ps
+#          onlysources.tex := main.tex
+#          LATEX_COLOR_WARNING := 'bold red uline'
+#
+#          And this would override the neverclean setting to ensure that pdf
+#          and ps files always remain behind, set the makefile to treat all
+#          .tex files that are not "main.tex" as includes (and therefore not
+#          default targets).  It also changes the LaTeX warning output to be
+#          red, bold, and underlined.
+#
+#          There are numerous variables in this file that can be overridden in
+#          this way.  Search for '?=' to find them all.
+#
+#          Also, you can put arbitrary targets into it if, for example, you
+#          want your source built from something else, e.g.:
+#
+#          generated.tex: generating_script.weird_lang depA depB
+#          	./generating_script.weird_lang > $$@
+#
+#          Note that if you are not careful, you can override the default
+#          target (what happens when you type "make" without arguments), so if
+#          you do use Makefile.ini, you probably want to start it with
+#          something like the following line:
+#
+#          default: all
+#
+#          Since the first target in any makefile is automatically the default,
+#          and the makefile already has a sensible "all" target, this will do
+#          what you want.
+#
+#          The Makefile.ini is imported before *anything else* is done, so go
+#          wild with your ideas for changes to this makefile in there.  It
+#          makes it easy to test them before submitting patches.
+#
+# STANDARD ENVIRONMENT VARIABLES:
+#
+#      LATEX_COLOR_WARNING		'$(LATEX_COLOR_WARNING)'
+#      LATEX_COLOR_ERROR		'$(LATEX_COLOR_ERROR)'
+#      LATEX_COLOR_UNDERFULL		'$(LATEX_COLOR_UNDERFULL)'
+#      LATEX_COLOR_OVERFULL		'$(LATEX_COLOR_OVERFULL)'
+#      LATEX_COLOR_PAGES		'$(LATEX_COLOR_PAGES)'
+#      LATEX_COLOR_BUILD		'$(LATEX_COLOR_BUILD)'
+#      LATEX_COLOR_GRAPHIC		'$(LATEX_COLOR_GRAPHIC)'
+#      LATEX_COLOR_DEP			'$(LATEX_COLOR_DEP)'
+#      LATEX_COLOR_SUCCESS		'$(LATEX_COLOR_SUCCESS)'
+#      LATEX_COLOR_FAILURE		'$(LATEX_COLOR_FAILURE)'
+#
+#   These may be redefined in your environment to be any of the following:
+#
+#      black
+#      red
+#      green
+#      yellow
+#      blue
+#      magenta
+#      cyan
+#      white
+#
+#   Bold or underline may be used, as well, either alone or in combination
+#   with colors:
+#
+#      bold
+#      uline
+#
+#   Order is not important.  You may want, for example, to specify:
+#
+#   export LATEX_COLOR_SUCCESS='bold blue uline'
+#
+#   in your .bashrc file.  I don't know why, but you may want to.
+#
+# STANDARD TARGETS:
+#
+#    all:
+#        Make all possible documents in this directory.  The documents are
+#        determined by scanning for .tex and .tex.sh (described in more detail
+#        later) and omitting any file that ends in ._include_.tex or
+#        ._nobuild_.tex.  The output is a set of .pdf files.
+#
+#        If you wish to omit files without naming them with the special
+#        underscore names, set the following near the top of the Makefile,
+#        or (this is recommended) within a Makefile.ini in the same directory:
+#
+#        	includes.tex := file1.tex file2.tex
+#
+#        This will cause the files listed to be considered as include files.
+#
+#        If you have only few source files, you can set
+#
+#        	onlysources.tex := main.tex
+#
+#        This will cause only the source files listed to be considered in
+#        dependency detection.  All other .tex files will be considered as
+#        include files.  Note that these options work for *any* source type,
+#        so you could do something similar with includes.gpi, for example.
+#        Note that this works for *any valid source* target.  All of the
+#        onlysources.* variables are commented out in the shipping version of
+#        this file, so it does the right thing when they simply don't exist.
+#        The comments are purely documentation.  If you know, for example, that
+#        file.mycoolformat is supported by this Makefile, but don't see the
+#        "onlysources.mycoolformat" declared in the comments, that doesn't mean
+#        you can't use it.  Go ahead and set "onlysources.mycoolformat" and it
+#        should do the right thing.
+#
+#    show:
+#        Builds and displays all documents in this directory.  It uses the
+#        environment-overridable value of VIEW_PDF (currently $(VIEW_PDF)) to
+#        do its work.
+#
+#    all-graphics:
+#        Make all of the graphics in this directory.
+#
+#    all-pstex (only for BUILD_STRATEGY=latex):
+#        Build all fig files into pstex and pstex_t files.  Gray DOES NOT WORK.
+#
+#    all-gray-pstex (only for BUILD_STRATEGY=latex):
+#    	 Build all fig files into grayscale pstex and pstex_t files.
+#
+#    all-dot2tex:
+#    	 Build all dot files into tex files.
+#
+#    show-graphics:
+#        Builds and displays all graphics in this directory.  Uses the
+#        environment-overridable value of VIEW_GRAPHICS (currently
+#        $(VIEW_GRAPHICS)) to do its work.
+#
+#    clean:
+#        Remove ALL generated files, leaving only source intact.
+#        This will *always* skip files mentioned in the "neverclean" variable,
+#        either in this file or specified in Makefile.ini:
+#
+#        	neverclean := *.pdf *.ps
+#
+#       The neverclean variable works on all "clean" targets below, as well.
+#
+#    clean-graphics:
+#        Remove all generated graphics files.
+#
+#    clean-backups:
+#        Remove all backup files: $(backup_patterns)
+#        (XFig and other editors have a nasty habit of leaving them around)
+#        Also removes Makefile-generated .temp files
+#
+#    clean-tex:
+#        Remove all files generated from LaTeX invocations except dependency
+#        information.  Leaves graphics alone.
+#
+#    clean-deps:
+#        Removes all auto-generated dependency information.
+#
+#    clean-auxiliary:
+#        Removes extra files created by various targets (like the dependency
+#        graph output).
+#
+#    clean-nographics:
+#        Cleans everything *except* the graphics files.
+#
+#    help:
+#        This help text.
+#
+#    version:
+#        Version information about this LaTeX makefile.
+#
+# DEBUG TARGETS:
+#
+#    _all_programs:
+#        A list of the programs used by this makefile.
+#
+#    _check_programs:
+#        Checks your system for the needed software and reports what it finds.
+#
+#    _check_gpi_files:
+#        Checks the .gpi files in the current directory for common errors, such
+#        as specification of the terminal or output file inside of the gpi file
+#        itself.
+#
+#    _dependency_graph:
+#        Outputs a .dot file to stdout that represents a graph of LaTeX
+#        dependencies.  To see it, use the _show_dependency_graph target or
+#        direct the output to a file, run dot on it, and view the output, e.g.:
+#
+#        make _dependency_graph > graph.dot
+#        dot -T ps -o graph.eps graph.dot
+#        gv graph.eps
+#
+#    _show_dependency_graph:
+#        Makes viewing the graph simple: extracts, builds and displays the
+#        dependency graph given in the _dependency_graph target using the value
+#        of the environment-overridable VIEW_POSTSCRIPT variable (currently set
+#        to $(VIEW_POSTSCRIPT)).  The postscript viewer is used because it
+#        makes it easier to zoom in on the graph, a critical ability for
+#        something so dense and mysterious.
+#
+#    _all_sources:
+#        List all .tex files in this directory.
+#
+#    _sources:
+#        Print out a list of all compilable sources in this directory.  This is
+#        useful for determining what make thinks it will be using as the
+#        primary source for 'make all'.
+#
+#    _scripts:
+#        Print out a list of scripts that make knows can be used to generate
+#        .tex files (described later).
+#
+#    _all_stems:
+#        Print a list of stems.  These represent bare targets that can be
+#        executed.  Listing <stem> as a bare target will produce <stem>.pdf.
+#
+#    _includes:
+#        A list of .d files that would be included in this run if _includes
+#        weren't specified.  This target may be used alone or in conjunction
+#        with other targets.
+#
+#    _graphic_outputs:
+#        A list of all generated .eps files
+#
+#    _env:
+#        A list of environment variables and their values.  If supported by
+#        your version of make, also a list of variables known to make.
+#
+# FILE TARGETS:
+#
+#    %, %.pdf:
+#        Build a PDF file from the corresponding %.tex file.
+#
+#        If BUILD_STRATEGY=pdflatex, then this builds the pdf directly.
+#        Otherwise, it uses this old-school but effective approach:
+#
+#            latex -> dvips -> ps2pdf
+#
+#        The BUILD_STRATEGY can be overridden in Makefile.ini in the same
+#        directory.  The default is pdflatex.
+#
+#        Reasons for using latex -> dvips include the "psfrag" package, and the
+#        generation of postscript instead of PDF.  Arguments for using pdflatex
+#        include "new and shiny" and "better supported."  I can't argue with
+#        either of those, and supporting them both didn't turn out to be that
+#        difficult, so there you have it.  Choices.
+#
+#    %._show:
+#        A phony target that builds the pdf file and then displays it using the
+#        environment-overridable value of VIEW_PDF ($(VIEW_PDF)).
+#
+#    %._graphics:
+#        A phony target that generates all graphics on which %.pdf (or %.dvi)
+#        depends.
+#
+#    %.ps (only for BUILD_STRATEGY=latex):
+#        Build a Postscript file from the corresponding %.tex file.
+#        This is done using dvips.  Paper size is automatically
+#        extracted from the declaration
+#
+#        \documentclass[<something>paper]
+#
+#        or it is the system default.
+#
+#        If using beamer (an excellent presentation class), the paper
+#        size is ignored.  More on this later.
+#
+#    %.dvi (only for BUILD_STRATEGY=latex):
+#        Build the DVI file from the corresponding %.tex file.
+#
+#    %.ind:
+#        Build the index for this %.tex file.
+#
+#    %.gls:
+#        Build the nomenclature glossary for this %.tex file.
+#
+#    %.nls:
+#        Build the (newer) nomenclature file for this %.tex file.
+#
+#    %.eps:
+#        Build an eps file from one of the following file types:
+#
+#       .dot    : graphviz
+#       .gpi    : gnuplot
+#       .fig    : xfig
+#       .xvg    : xmgrace
+#       .svg    : scalable vector graphics (goes through inkscape)
+#       .png    : png (goes through NetPBM)
+#       .jpg	: jpeg (goes through ImageMagick)
+#       .eps.gz : gzipped eps
+#
+#       The behavior of this makefile with each type is described in
+#       its own section below.
+#
+#    %.pstex{,_t} (only for BUILD_STRATEGY=latex):
+#       Build a .pstex_t file from a .fig file.
+#
+# FEATURES:
+#
+#    Optional Binary Directory:
+#        If you create the _out_ directory in the same place as the makefile,
+#        it will automatically be used as a dumping ground for .pdf (or .dvi,
+#        .ps, and .pdf) output files.
+#
+#        Alternatively, you can set the BINARY_TARGET_DIR variable, either as a
+#        make argument or in Makefile.ini, to point to your directory of
+#        choice.  Note that no pathname wildcard expansion is done in the
+#        makefile, so make sure that the path is complete before going in
+#        there.  E.g., if you want to specify something in your home directory,
+#        use $$HOME/ instead of ~/ so that the shell expands it before it gets
+#        to the makefile.
+#
+#    External Program Dependencies:
+#        Every external program used by the makefile is represented by an
+#        ALLCAPS variable at the top of this file.  This should allow you to
+#        make judgments about whether your system supports the use of this
+#        makefile.  The list is available in the ALL_PROGRAMS variable and,
+#        provided that you are using GNU make 3.80 or later (or you haven't
+#        renamed this file to something weird like "mylatexmakefile" and like
+#        invoking it with make -f) can be viewed using
+#
+#        make _all_programs
+#
+#        Additionally, the availability of these programs can be checked
+#        automatically for you by running
+#
+#        make _check_programs
+#
+#        The programs are categorized according to how important they are and
+#        what function they perform to help you decide which ones you really
+#        need.
+#
+#    Colorized Output:
+#        The output of commands is colorized to highlight things that are often
+#        important to developers.  This includes {underfull,overfull}
+#        {h,v}boxes, general LaTeX Errors, each stage of document building, and
+#        the number of pages in the final document.  The colors are obtained
+#        using 'tput', so colorization should work pretty well on any terminal.
+#
+#        The colors can be customized very simply by setting any of the
+#        LATEX_COLOR_<CONTEXT> variables in your environment (see above).
+#
+#    Predecessors to TeX Files:
+#        Given a target <target>, if no <target>.tex file exists but a
+#        corresponding script or predecessor file exists, then appropriate
+#        action will be taken to generate the tex file.
+#
+#        Currently supported script or predecessor languages are:
+#
+#        sh:     %.tex.sh
+#        perl:   %.tex.pl
+#        python: %.tex.py
+#
+#           Calls the script using the appropriate interpreter, assuming that
+#           its output is a .tex file.
+#
+#           The script is called thus:
+#
+#              <interpreter> <script file name> <target tex file>
+#
+#           and therefore sees exactly one parameter: the name of the .tex
+#           file that it is to create.
+#
+#           Why does this feature exist?  I ran into this while working on
+#           my paper dissertation.  I wrote a huge bash script that used a
+#           lot of sed to bring together existing papers in LaTeX.  It
+#           would have been nice had I had something like this to make my
+#           life easier, since as it stands I have to run the script and
+#           then build the document with make.  This feature provides hooks
+#           for complicated stuff that you may want to do, but that I have
+#           not considered.  It should work fine with included dependencies,
+#           too.
+#
+#           Scripts are run every time make is invoked.  Some trickery is
+#           employed to make sure that multiple restarts of make don't cause
+#           them to be run again.
+#
+#        reST: %.rst
+#
+#           Runs the reST to LaTeX converter to generate a .tex file
+#           If it finds a file names _rststyle_._include_.tex, uses it as
+#           the "stylesheet" option to rst2latex.
+#
+#           Note that this does not track sub-dependencies in rst files.  It
+#           assumes that the top-level rst file will change if you want a
+#           rebuild.
+#
+#    Dependencies:
+#
+#        In general, dependencies are extracted directly from LaTeX output on
+#        your document.  This includes
+#
+#        *    Bibliography information
+#        *    \include or \input files (honoring \includeonly, too)
+#        *    Graphics files inserted by the graphicx package
+#
+#        Where possible, all of these are built correctly and automatically.
+#        In the case of graphics files, these are generated from the following
+#        file types:
+#
+#        GraphViz:      .dot
+#        GNUPlot:       .gpi
+#        XFig:          .fig
+#        XMgrace:       .xvg
+#        SVG:           .svg
+#        PNG:           .png
+#        JPEG:          .jpg
+#        GZipped EPS:   .eps.gz
+#
+#        If the file exists as a .eps already, it is merely used (and will not
+#        be deleted by 'clean'!).
+#
+#        LaTeX and BibTeX are invoked correctly and the "Rerun to get
+#        cross-references right" warning is heeded a reasonable number of
+#        times.  In my experience this is enough for even the most troublesome
+#        documents, but it can be easily changed (if LaTeX has to be run after
+#        BibTeX more than three times, it is likely that something is moving
+#        back and forth between pages, and no amount of LaTeXing will fix
+#        that).
+#
+#        \includeonly is honored by this system, so files that are not
+#        specified there will not trigger a rebuild when changed.
+#
+#    Beamer:
+#        A special TeX source comment is recognized by this makefile (only when
+#        BUILD_STRATEGY=latex, since this invokes psnup):
+#
+#        %%[[:space:]]*BEAMER[[:space:]]*LARGE
+#
+#        The presence of this comment forces the output of dvips through psnup
+#        to enlarge beamer slides to take up an entire letter-sized page.  This
+#        is particularly useful when printing transparencies or paper versions
+#        of the slides.  For some reason landscape orientation doesn't appear
+#        to work, though.
+#
+#        If you want to put multiple slides on a page, use this option and then
+#        print using mpage, a2ps, or psnup to consolidate slides.  My personal
+#        favorite is a2ps, but your mileage may vary.
+#
+#        When beamer is the document class, dvips does NOT receive a paper size
+#        command line attribute, since beamer does special things with sizes.
+#
+#    GNUPlot Graphics:
+#        When creating a .gpi file, DO NOT INCLUDE the "set terminal" or "set
+#        output" commands!  The makefile will include terminal information for
+#        you.  Besides being unnecessary and potentially harmful, including the
+#        terminal definition in the .gpi file makes it harder for you, the one
+#        writing the document, to preview your graphics, e.g., with
+#
+#           gnuplot -persist myfile.gpi
+#
+#        so don't do specify a terminal or an output file in your .gpi files.
+#
+#        When building a gpi file into an eps file, there are several features
+#        available to the document designer:
+#
+#        Global Header:
+#            The makefile searches for the files in the variable GNUPLOT_GLOBAL
+#            in order:
+#
+#            ($(GNUPLOT_GLOBAL))
+#
+#            Only the first found is used.  All .gpi files in the directory are
+#            treated as though the contents of GNUPLOT_GLOBAL were directly
+#            included at the top of the file.
+#
+#            NOTE: This includes special comments! (see below)
+#
+#        Font Size:
+#            A special comment in a .gpi file (or a globally included file) of
+#            the form
+#
+#            ## FONTSIZE=<number>
+#
+#            will change the font size of the GPI output.  If font size is
+#            specified in both the global file and the GPI file, the
+#            specification in the individual GPI file is used.
+#
+#        Grayscale Output:
+#            GNUplot files also support a special comment to force them to be
+#            output in grayscale *no matter what*:
+#
+#            ## GRAY
+#
+#            This is not generally advisable, since you can always create a
+#            grayscale document using the forms mentioned above.  But, if your
+#            plot simply must be grayscale even in a document that allows
+#            colors, this is how you do it.
+#
+#    XFig Graphics:
+#            No special handling is done with XFig, except when a global
+#            grayscale method is used, e.g.
+#
+#                make GRAY=1 document
+#
+#            In these cases the .eps files is created using the -N switch to
+#            fig2dev to turn off color output.  (Only works with eps, not pstex
+#            output)
+#
+#    GraphVis Graphics:
+#            Color settings are simply ignored here.  The 'dot' program is used
+#            to transform a .dot file into a .eps file.
+#
+#            If you want, you can use the dot2tex program to convert dot files
+#            to tex graphics.  The default is to just call dot2tex with no
+#            arguments, but you can change the DOT2TEX definition to include
+#            options as needed (in your Makefile.ini).
+#
+#            Note that, as with pstex, the makefile cannot use latex's own
+#            output to discover all missing dot_t (output) files, since anytime
+#            TeX includes TeX, it has to bail when it can't find the include
+#            file.  It can therefore only stop on the first missing file it
+#            discovers, and we can't get a large list of them out easily.
+#
+#            So, the makefile errors out if it's missing an included dot_t
+#            file, then prompts the user to run this command manually:
+#
+#                make all-dot2tex
+#
+#    GZipped EPS Graphics:
+#
+#        A .eps.gz file is sometimes a nice thing to have.  EPS files can get
+#        very large, especially when created from bitmaps (don't do this if you
+#        don't have to).  This makefile will unzip them (not in place) to
+#        create the appropriate EPS file.

+\section{Geodatenimport}
+
+Der Geodaten Importer ist ein in Python geschriebenes Kommandozeilen Tool zum
+Import von Shapefiles in eine Datenbank. Zum Lesen der Shapefiles und zum
+Schreiben der Geodaten in die Datenbank wird GDAL verwendet. Der Import in eine
+Oracle Datenbank erfordert, dass GDAL und GDAL Python Bindungs mit
+Oracle Unterstützung installiert sind. Weitere Details hierzu befinden sich im
+Kapitel \ref{Systemanforderungen} und \ref{Installationsanleitung}.
+
+Der Importer kann mit einem Shellscript von der Kommandozeile gestartet werden
+(siehe Kapitel \ref{Starten des Geodaten Importers}). Nach dem Start wird anhand der
+Konfiguration festgestellt, welche Klassen von Shapefiles aus dem Dateisystem
+importiert werden sollen. Für jede Klasse gibt es einen speziellen
+Parser, der die speziellen Attribute eines Shapefiles liest und in die entsprechende
+Relation der Datenbank schreibt. Die Parser sind speziell auf das
+Dateisystem der BfG ausgerichtet. So wird z.B. erwartet, dass die Shapefiles der
+Gewässerachse im Ordner $Geodaesie/Flussachse+km$ liegen. Weitere Informationen zu
+den einzelnen Parsern sind dem nächsten Kapitel \ref{Beschreibung der Parser} zu
+entnehmen. Der Erfolg oder Misserfolg eines Shape-Imports wird je nach
+Konfiguration im Logfile vermerkt. Folgende Einträge können dem Logfile
+entnommen werden:
+
+\textbf{INFO: Inserted 4 features}
+\\Gibt die Anzahl der erfolgreich importierten Features an.\\
+
+\textbf{INFO: Failed to create 2 features}
+\\Gibt die Anzahl der Features an, die nicht importiert werden konnten.\\
+
+\textbf{INFO: Found 3 unsupported features}
+\\Gibt die Anzahl der Features an, die aufgrund ihres Datentyps nicht importiert
+werden konnten. Z.B: es werden Linien erwartet, im Shapefile sind jedoch
+Polygone enthalten.\\
+
+\textbf{ERROR: No source SRS given! No transformation possible!}
+\\Das Shapefile enthält keine Information, in welcher Projektion die Geometrien
+vorliegen. Es findet keine Transformation in die Zielprojektion statt. Bitte
+beachten Sie, dass FLYS diese Geometrien später ggf nicht korrekt darstellen
+kann.
+
+\textbf{ERROR: Unable to insert feature: DETAIL}
+\\Beim Lesen der Attribute eines Features ist ein Fehler aufgetreten.
+Das Feature konnte nicht in die Datenbank geschrieben werden.\\
+
+\textbf{ERROR: Exception while committing transaction}
+\\Beim Abschluss des Schreib-Vorgangs in die Datenbank ist ein unerwarteter
+Fehler aufgetreten. Die Features des Shapes sind nicht importiert worden.\\
+
+\textbf{ERROR 1: ORA-01017: invalid username/password; logon denied}
+\\Es konnte keine Verbindung zur Oracle Datenbank hergestellt werden. Prüfen Sie
+die Verbindungseinstellungen.
+
+Damit die Geodaten eines Shapes später eindeutig in der Datenbank identifiziert
+werden können, wird für jede Geometrie der Pfad des Shapes im Dateisystem in
+einer Spalte der Datenbank gespeichert. Anwendungen, die auf der Datenbank
+aufbauen, können die Geodaten eines Shapefiles später anhand dieses Merkmals
+gruppieren und anzeigen.
+
+
+\subsection{Beschreibung der Parser}
+\label{Beschreibung der Parser}
+
+Wie im letzten Kapitel beschrieben, sind die Parser speziell an das Dateisystem
+der BfG ausgerichtet. Im Folgenden werden zu jedem Parser folgende Informationen

+\subsection{Systemanforderungen}
+\label{Systemanforderungen}
+\begin{itemize}
+  \item Oracle Datenbank inkl. Schema für FLYS
+  \item GDAL Binding für Python mit Oracle Support
+  \item ogr2ogr
+  \item Python $>=$ 2.6
+\end{itemize}
+
+
+\subsection{Installationsanleitung}
+\label{Installationsanleitung}
+\begin{itemize}
+
+ \item Python\\
+ Zum Starten des Importers ist es notwendig Python zu installieren. Dies können
+ Sie mit folgendem Befehl auf der Kommandozeile erledigen:
+
+ \begin{lstlisting}
+    zypper in python
+ \end{lstlisting}
+
+ \item Oracle Instantclient\\
+ Der Oracle Instantclient 11.2 wird benötigt, damit der Importer mittels Python
+ und GDAL in die bestehende Oracle Datenbank schreiben kann. Dazu ist es
+ erforderlich, folgende Archive von Oracle herunterzuladen. Zu finden sind die
+ folgenden Pakete unter\\
+ \href{http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html}{http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html}
+
+ \begin{itemize}
+    \item instantclient-basic-linux-x86-64-11.2.0.2.0.zip
+    \item instantclient-sdk-linux-x86-64-11.2.0.2.0.zip
+    \item instantclient-sqlplus-linux-x86-64-11.2.0.2.0.zip
+ \end{itemize}
+
+ Anschließend führen Sie folgende Befehle auf der Kommandozeile aus:
+
+ \begin{lstlisting}
+
+    mkdir /opt
+
+    unzip ~/instantclient-basic-linux-x86-64-11.2.0.2.0.zip -d /opt
+    unzip ~/instantclient-sdk-linux-x86-64-11.2.0.2.0.zip -d /opt
+    unzip ~/instantclient-sqlplus-linux-x86-64-11.2.0.2.0.zip -d /opt
+
+    mkdir /opt/instantclient_11_2/lib
+    cd /opt/instantclient_11_2/lib
+    ln -s ../libclntsh.so.11.1 .
+    ln -s ../libclntsh.so.11.1 libclntsh.so
+    ln -s ../libnnz11.so .
+    ln -s ../libocci.so.11.1 .
+    ln -s ../libocci.so.11.1 libocci.so
+    ln -s ../libociei.so .
+    ln -s ../libocijdbc11.so .
+    ln -s ../libsqlplusic.so .
+    ln -s ../libsqlplus.so .
+
+    rpm -i --nodeps ~/flys-importer/rpm/RPMS/x86_64/libgdal1180-1.8.0-intevation1.x86_64.rpm 
+    rpm -i --nodeps ~/flys-importer/rpm/RPMS/x86_64/libgdal180-devel-1.8.0-intevation1.x86_64.rpm
+    rpm -i --nodeps ~/flys-importer/rpm/RPMS/x86_64/gdal180-1.8.0-intevation1.x86_64.rpm
+
+ \end{lstlisting}
+
+ Sollten keine Fehler aufgetreten sein, haben Sie den \textit{Oracle
+ Instantclient 11.2} erfolgreich entpackt und im Dateisystem unter
+ \textit{/opt/instantclient\_11\_2} abgelegt. Mit den Befehlen $rpm -i --nodeps$
+ haben Sie anschließend die notwendigen Bindings installiert, damit der Importer
+ die Geodaten in die Oracle Datenbank schreiben kann.
+
+\end{itemize}
+
+
+\subsection{Konfiguration}
+\label{Konfiguration}
+Der Geodaten Importer kann über die Datei \textit{contrib/run\_geo.sh}
+konfiguriert werden. Öffnen Sie die Datei mit einem Texteditor Ihrer Wahl.
+In den Zeilen 4-9 werden Optionen definiert, die zwangsläufig angepasst
+werden müssen:
+
+\textbf{RIVER\_PATH}
+\\Der Pfad zum Gewässer im Dateisystem.
+
+\textbf{RIVER\_ID}
+\\Die Datenbank ID des zu importierenden Gewässers.
+
+\textbf{TARGET\_SRS}
+\\Das EPSG Referenzsystem in das die Geodaten beim Import projeziert werden
+sollen.
+
+\textbf{HOST}
+\\Der Host der Datenbank.
+
+\textbf{USER}
+\\Der Nutzer, der zum Verbinden zur Datenbank verwendet wird.
+
+\textbf{PASS}
+\\Das Passwort für USER zum Verbinden zur Datenbank.
+
+In den Zeilen 12-23 werden weitere Optionen definiert, die bei Bedarf angepasst
+werden können. Falls nicht anders angegeben, können die Optionen mit den Werten
+`0` und `1` belegt werden.

+\subsection{Starten des Geodaten Importers}
+\label{Starten des Geodaten Importers}
+Der Geodaten Importer wird mittels eines Shellskripts von einer Konsole
+gestartet. Dazu führen Sie folgenden Befehl aus:\\
+
+\begin{lstlisting}
+    sh contrib/run_geo.sh > geo-import.log
+\end{lstlisting}
+
+Der Importer wird nun gestartet. Sämtliche Log-Ausgaben werden in die Datei
+$geo-import.log$ geschrieben.
+
+\textbf{Hinweis}
+\\Bitte beachten Sie, dass der Geodaten Importer aufgrund der eingesetzten
+Technologien derzeit nicht in der Lage ist, lesend auf die Oracle Datenbank
+zuzugreifen. Entsprechend kann beim Import nicht festgestellt werden, ob sich
+Shapefiles bereits in der Datenbank befinden, oder nicht. Ein erneuter Import
+Vorgang der Geodaten würde also dazu führen, dass Geometrien doppelt in der
+Datenbank abgelegt werden.

+\section{Fachdatenimport}
+
+Der Fachdatenimporter dient dazu, hydrologische und morphologische Gewässerdaten
+aus dem Dateisystem in die FLYS3-Datenbank zu importieren. Das Werkzeug
+orientiert sich hierbei an der Dateihierachie, so wie sie auch von Desktop-FLYS
+ausgelesen wird. Der Import Vorgang ist in zwei Phasen unterteilt:
+
+\begin{itemize}
+    \item Lesen aller Daten eines Gewässers aus dem Dateisystem.
+    \item Schreiben der erfolgreich eingelesenen Daten in die Datenbank.
+\end{itemize}
+
+Sollte beim Lese- oder Schreib-Vorgang eines Gewässers ein Fehler auftreten, so
+werden sämtliche Daten des Gewässers verworfen. Beide Phasen zusammen bilden
+somit eine Transaktion.
+
+\textbf{Hinweis}
+\\Der Import geht wie auch Desktop-FLYS davon aus, dass die Dateien Latin-1
+encodiert vorliegen! Stellen Sie also sicher, dass das von Ihnen verwendete
+Encoding korrekt ist. Andernfalls ist es möglich, dass es während des Imports zu
+unerwarteten Problemen kommt.
+
+Der Importer ist ein in Java geschriebenes Werkzeug und kann von der Konsole aus
+gestartet werden. Sämtlich Konfigurationen können über sogenannte
+\textit{System-Properties} übergeben werden. Eine \textit{System-Property} wird
+dabei mittels \textit{-Dkey=value} beim Start übergeben. Im folgenden Beispiel
+würde der Importer mit einer Konfiguration \textit{flys.backend.importer.dry.run},
+welche den Wert \textit{true} gesetzt hat, gestartet.
+
+\begin{lstlisting}
+    java -Dflys.backend.importer.dry.run=true de.intevation.flys.importer.Importer
+\end{lstlisting}
+
+Auf gleiche Weise können dem Importer sämtliche Optionen zur Konfiguration
+beim Start mitgegeben werden. Im folgenden werden die möglichen System-Properties und
+ihre Auswirkung auf den Import genauer beschrieben. In den Kapiteln
+\ref{configuration} und \ref{start-hydr} wird zur Einfachheit jedoch ein
+Shellskript verwendet, das eine Standardkonfiguration vorgibt und den Importer
+mit allen erforderlichen Konfigurationen startet.
+
+
+\subsection{Importierte Daten}
+In diesem Kapitel werden die Datentypen aufgelistet und erläutert, wie sie vom
+Importer eingelesen werden.
+
+\subsubsection{Streckenfavoriten (*.km-Dateien)}
+Der Import der Streckenfavoriten kann mit \textbf{-Dflys.backend.importer.skip.annotations=true}
+unterdrückt werden.
+
+Zur Klassifikation von Streckenfavoriten muss mittels\\
+\textbf{-Dflys.backend.importer.annotation.types=DATEI} der Pfad zu einer
+XML-Datei angegeben werden. In dieser Datei werden die Typen und Regeln
+festgelegt, anhand derer die Klassifikation während des Import-Vorgangs
+vorgenommen wird. Details hierzu befinden sich im Kapitel \ref{annotation-types}.
+
+\subsubsection{Pegel, Stammdaten (*.glt, *.sta-Dateien)}
+Der Import von Pegel- und Stammdaten kann mit \textbf{'-Dflys.backend.importer.skip.gauges=true'}
+unterdrückt werden. Die .glt-Datei, die neben der .wst-Datei liegt, wird zuerst
+ausgelesen. Es werden nur *.sta-Datei von Pegeln geladen, die in der .glt-Datei
+vermerkt sind.
+
+Mittels \textbf{-Dflys.backend.sta.parse.gauge.numbers=true'} wird versucht, die
+offiziellen Pegelnummern aus den Stammdaten zu extrahieren.
+\textbf{Dies ist mit Vorsicht zu behandeln, denn die meisten STA-Dateien
+enthalten invalide Pegelnummern.}
+
+Die System-Property \textbf{flys.backend.main.value.types} kann einen String
+mit gültigen Typen von Stammdaten enthalten. Vorbelegt ist \textit{QWTD}. In der
+Praxis ist \textit{QWD} eine sinnvolle Belegung.

+unterdrückt werden. Es werden rekursiv alle *.prf-Dateien aus \textit{../../..}
+relativ zur gewaesser.wst-Datei betrachtet. Vor dem Import werden mit Hilfe
+eines Längen- und eines MD5-Summen-Vergleichs inhaltliche Duplikate
+ausgeschlossen.
+
+\subsubsection{Hydraulische Kennzahlen (*.hyk)}
+Der Import von hydraulischen Kennzahlen kann mit \textbf{-Dflys.backend.importer.skip.hyks=true} unterdrückt
+werden. Es werden rekursiv alle *.hyk-Dateien aus \textit{../../..} relativ zur

+
+
+\subsection{Klassifikation von Streckenfavoriten}
+\label{annotation-types}
+Streckenfavoriten werden aus KM-Dateien importiert. Um die einzelnen Einträge
+einer Kategorie (Brücke, Pegel, etc.) zuzuordnen, kann eine XML angegeben werden,
+in der Regeln für diese Klassifikation definiert werden. Schematisch gliedert
+sich diese Datei in die zwei Bereiche 'types' und 'patterns':
+
+\begin{lstlisting}
+    <annotation>
+        <types>
+            <type>...</type>
+            <type>...</type>
+            ...
+        </types>
+        <patterns>
+            <pattern>...</pattern>
+            <pattern>...</pattern>
+            ...
+        </patterns>
+    </annotation>
+\end{lstlisting}
+
+In der Sektion \textit{types} werden die Kategorien vereinbart, in die klassifiziert
+werden soll. Dies geschieht mit entsprechenden Zeilen in der XML Datei. Es folgt
+ein Auszug aus einer solchen Datei:
+
+\begin{lstlisting}
+  <type name="Pegel"/>
+  <type name="Brücke"/>
+  ...
+  <type name="Sonstige" default="true"/>
+\end{lstlisting}
+
+Das Attribut 'default' darf maximal einmal vergeben werden und besagt, dass diese
+Kategorie gewählt werden soll, wenn keine andere Kategorie zugeordnet werden kann.
+
+In der Sektion 'patterns' werden dann die Regeln definiert, die einzelne Einträge
+den zuvor definierten Kategorien zuordnet. Hierfür können zwei Arten von
+Definitionen angegeben werden:
+
+\begin{lstlisting}
+  <file pattern="^Brücken$" type="Brücke"/>
+\end{lstlisting}
+
+oder
+
+\begin{lstlisting}
+  <line pattern="^Brücke[:\s].*$" type="Brücke"/>
+\end{lstlisting}
+
+Die erste Variante bestimmt die Kategorie, die pro KM-Datei gelten soll.
+\textit{pattern} ist hierbei ein regulärer Ausdruck, der auf den Dateinamen
+angewandt wird. Passt der Name der Datei auf den regulären Ausdruck, wird
+\textit{type} als Vorgabe angenommen. Treffen mehrere \textit{file}-Regeln zu,
+wird der erste Treffer angewandt. Findet keine der \textit{file}-Regeln Anwendung, wird
+die Kategorie ausgewählt, die in der \textit{types}-Section das Attribut
+\textit{default} gesetzt hat.
+
+Die zweite Regel-Variante \textit{line} wird auf jeden Eintrag innerhalb einer KM-Datei
+auf den Bezeichner der Streckenfavoriten angewandt. Als Muster dient auch hier
+ein regulärer Ausdruck, der über das Attribut \textit{pattern} definiert wird.
+Die Kategorie wird im Trefferfall über das Attribut \textit{type} bestimmt.
+Treffen mehrere Regeln zu, wird die Kategorie gewählt, die zum ersten Treffer
+gehört. Trifft keine Regel zu wird der Eintrag der Kategorie zugeteilt, die für
+die beinhaltende Datei als Vorgabe gilt.
+
+
+\subsection{Konfiguration}
+\label{configuration}
+Zum Starten des Importers ist es notwendig, in der Datei
+\textit{contrib/run\_hydr\_morph.sh} die Variablen am Anfang der Datei
+anzupassen. Im folgenden werden notwendige und optionale Einstellungen
+beschrieben, die beim Starten des Importers berücksichtigt werden. Folgende
+Einstellungen sind zwangsläufig an die bestehende Umgebung anzupassen:
+
+\textbf{INFO\_GEW}
+\\Diese Option muss auf eine valide *.gew Datei verweisen (bekannt aus
+Desktop-FLYS). Wichtig für den Importer sind in dieser Datei die Zeilen, die mit
+\textit{WSTDatei:} beginnen. In ihnen wird der Pfad zu der zentralen WST-Datei
+des jeweiligen Gewässers angegeben. Alle anderen importierten Dateien werden in
+ihrer Lage im Dateisystem relativ zur Lage dieser Datei betrachtet.
+
+\textbf{BACKEND\_USER}
+\\Der Nutzername, der zum Verbinden zur Datenbank verwendet werden soll.
+
+\textbf{BACKEND\_PASS}
+\\Das Passwort, welches in Kombination mit \textbf{BACKEND\_USER} zum Verbinden
+zur Datenbank verwendet werden soll.
+
+\textbf{BACKEND\_HOST}
+\\Der Datenbank-Host. In der Regel sollte hier \textit{localhost} eingetragen
+werden, da es empfohlen wird, den Importer auf dem selben Host zu starten, auf
+dem auch die Datenbank läuft.
+
+\textbf{BACKEND\_PORT}
+\\Der Port auf dem die Datenbank zu erreichen ist. Bei einer Oracle XE Instanz
+z.B.: \textit{1521}, sofern nicht anders konfiguriert.
+
+\textbf{BACKEND\_NAME}
+\\Der Name der Datenbank Instanz. Beispielsweise \textit{XE} bei einer Oracle XE
+Instanz.
+
+\textbf{BACKEND\_DB\_PREFIX}
+\\Der Präfix zum Aufbau einer Datenbankverbindung. Für Oracle z.B.: \textit{jdbc:oracle:thin:@}.
+
+\textbf{BACKEND\_DB\_DRIVER}
+\\Der Name des JDBC-Treibers, der es erlaubt das Protokoll der Datenbank zu
+sprechen. Im Falle einer Oracle XE wäre dies z.B.: \textit{oracle.jdbc.OracleDriver}.
+
+\textbf{BACKEND\_DB\_DIALECT}
+\\Der Hibernate-Dialekt, den die Datenbank versteht. Im Falle einer Oracle-XE
+wäre dies z.B.: \textit{org.hibernate.dialect.OracleDialect}.
+
+
+Weitere Details zum Verbinden zu einer Oracle Datenbank finden Sie unter\\
+\href{http://www.orafaq.com/wiki/JDBC}{http://www.orafaq.com/wiki/JDBC}. Alle weiteren Einstellungen sind
+optional anpassbar:
+
+\textbf{LOG4J\_CONFIG}
+\\Der Fachdatenimport verwendet die externe Bibliothek \textit{Apache Log4J} zum Loggen
+von Informationen. Dazu ist es notwendig eine entsprechende Konfiguration beim
+Start anzugeben. \textit{LOG4J\_CONFIG} verweist in diesem Fall auf eine externe
+Datei zur Konfiguration von Log4J. Im Standardfall wird die Datei
+\textit{conf/log4j.properties} verwendet, welche eine sinnvolle Standardkonfiguration
+enthält. Sollten Sie diese Konfiguration verwenden, wird beim Import eine
+Log-Datei namens \textit{import.log} erstellt, die maximal 100 MB groß werden
+kann. Sollte die Log-Datei größer als 100 MB anwachsen, wird die aktuelle Datei
+nach \textit{import.log.1} umbenannt und eine neue Datei \textit{import.log}
+wird begonnen. Maximal werden 10 Log-Dateien gespeichert. Für weitere Details
+zu Log4J siehe Online Dokumentation unter
+\href{http://logging.apache.org/log4j/1.2/}{http://logging.apache.org/log4j/1.2/}
+
+
+\textbf{IMPORTER\_MAINVALUE\_TYPES}
+\\Diese Einstellung erlaubt die Angabe eines Textes, der aus den gültigen Typen
+für Hauptwerte zusammengesetzt ist. \textit{QWTD} ist standardmäßig gesetzt.
+
+\textbf{IMPORTER\_ANNOTATION\_TYPES}
+\\Diese Einstellung verweist auf eine Datei (relativ zum Ort der \textit{run.sh}
+im Dateisystem), die die möglichen Typen von Streckenfavoriten und deren Regeln
+definiert. Siehe hierzu auch Kapitel \ref{annotation-types}.
+
+
+Die im folgenden beschriebenen Einstellungen können jeweils die Werte
+\textit{true} oder \textit{false} annehmen und sind optional anzupassen.
+
+\textbf{IMPORTER\_DRY\_RUN}
+\\Falls \textit{true} gesetzt wird, wird der Import nur simuliert. Es werden
+keine Daten in die Datenbank geschrieben. Dies kann z.B.: zum Ermitteln
+potentieller Dateninkonsistenzen sinnvoll sein.
+
+\textbf{IMPORTER\_SKIP\_GAUGES}
+\\Wenn \textit{true} gesetzt ist werden keine Pegel- und Stammdaten bearbeitet.
+
+\textbf{IMPORTER\_SKIP\_ANNOTATIONS}
+\\Wenn \textit{true} gesetzt ist werden keine Streckenfavoriten bearbeitet.
+
+\textbf{IMPORTER\_SKIP\_WST}
+\\Wenn \textit{true} gesetzt ist werden keine WST Dateien bearbeitet.

+\\Wenn \textit{true} gesetzt ist werden keine Hochwasserschutzanlagen
+bearbeitet.
+
+\textbf{IMPORTER\_SKIP\_BED\_HEIGHT\_SINGLE}
+\\Wenn \textit{true} gesetzt ist werden keine mittleren Sohlhöhen (Peilungen) bearbeitet.
+
+\textbf{IMPORTER\_SKIP\_BED\_HEIGHT\_EPOCH}
+\\Wenn \textit{true} gesetzt ist werden keine mittleren Sohlhöhen (Epochen)
+bearbeitet.
+
+\textbf{IMPORTER\_SKIP\_SEDIMENT\_DENSITY}
+\\Wenn \textit{true} gesetzt ist werden keine Dateien zur Sedimentdichte
+bearbeitet.
+
+\textbf{IMPORTER\_SKIP\_MORPHOLOGICAL\_WIDTH}
+\\Wenn \textit{true} gesetzt ist wird keine morphologische Breite bearbeitet.
+
+\textbf{IMPORTER\_SKIP\_FLOW\_VELOCITY}
+\\Wenn \textit{true} gesetzt ist werden keine Fließgeschwindigkeiten bearbeitet.

+\subsection{Hinweise zum Betrieb}
+Aufgrund des hohen Speicherverbrauchs des Importers wird empfohlen, der JVM
+mindestens 8 GiB Hauptspeicher zuzuordnen. Dies kann beim Starten des Java
+Prozesses mittels folgendem Parameter '-Xmx8192m' getan werden. Das
+Shellskript zum Starten des Importers setzt diesen Wert standardmäßig.
+Besonders speicherintensiv ist der Import der HYKs und der PRFs.
+Hier ist es unter Umständen empfehlenswert, diese in zwei oder drei
+Schritten zu importieren. Zuerst die sonstigen hydrologischen Daten importieren;
+anschließend einen Import-Vorgang ausschließlich für HYKs starten; anschließend
+einen Import-Vorgang für PRFs starten. Siehe Kapitel \ref{configuration} für
+weitere Informationen zum Aktivieren/Deaktivieren einzelner Dateitypen beim
+Import.
+
+
+\subsection{Starten des Fachdaten Importers}
+\label{start-hydr}
+Der Fachdaten Importer wird mit Hilfe eines Shellskripts von einer Konsole
+gestartet. Dazu führen folgenden Befehl aus:\\
+
+\begin{lstlisting}
+    contrib/run_hydr_morph.sh
+\end{lstlisting}
+
+Nachdem der Prompt der Konsole zurückkehrt, ist der Import abgeschlossen oder es
+ist ein Fehler aufgetreten. Weitere Informationen entnehmen Sie der Log-Datei.

+\section{Übersicht}
+
+Diese Dokumentation beschreibt die von Intevation entwickelten Werkzeuge zum
+Importieren der hydrologischen, morphologischen und geodätischen Daten der BfG.
+Die im folgenden\\ beschriebenen Werkzeuge zum Importieren der fachlichen und
+geodätischen Daten sind speziell auf das Verzeichnissystem der BfG ausgerichtet.
+Dabei wird angenommen, dass sich das Verzeichnis eines Gewässers auf oberster
+Ebene in drei Unterverzeichnisse aufgliedert:
+
+\begin{itemize}
+    \item Geodaesie
+    \item Hydrologie
+    \item Morphologie
+\end{itemize}
+
+Desweiteren beziehen sich die Befehle, die auf der Kommandozeile abgesetzt
+werden, auf ein SuSE-Linux-Enterprise-Server Version 11. Bitte beachten Sie
+auch, dass einige der Befehle \textit{root}-Rechte benötigen.
+
+\subsection{Vorbereitungen}
+
+\subsubsection{Entpacken des Datenimporters}
+
+Damit die Software performant und korrekt ausgeführt werden kann, ist es
+erforderlich, dass sie auf dem selben System installiert und ausgeführt wird,
+wie auch die Datenbank installiert ist. Sollten Sie das Paket nicht auf dem
+Zielsystem selbst heruntergeladen haben, sind ggf. weitere Werkzeuge notwendig.
+Im Fall, dass das Sie von einem Windows System auf das Zielsystem zugreifen
+wollen, können Sie beispielsweise folgende Werkzeuge verwenden:
+
+\begin{itemize}
+\item WinSCP \\
+WinSCP ist ein Open Source Werkzeug zum Transferieren von Dateien zwischen zwei
+Systemen. Um das heruntergeladene Paket auf das Zielsystem zu transferieren,
+können Sie WinSCP benutzen. Für weitere Informationen und den Gebrauch von
+WinSCP lesen Sie bitte unter folgender Adresse nach:
+\href{http://winscp.net/}{http://winscp.net/}.
+
+\item Putty \\
+Putty ist ein Open Source Werkzeug, mit dem Sie sich von einem Windows System
+per SSH auf das Zielsystem verbinden können. Anschließend können Sie über die
+Kommandozeile auf dem Zielsystem die Befehle, die in diesem Dokument beschrieben
+sind, ausführen. Für weitere Informationen zu Putty und dessen Gebrauch lesen
+Sie bitte unter folgender Adresse nach: \href{http://www.putty.org/}
+{http://www.putty.org/}.
+\end{itemize}
+
+Bitte beachten Sie, dass diese Werkzeuge nicht zur Installtion und zum Betrieb
+der Software selbst notwendig sind!
+
+
+\subsubsection{Vorbereiten der Datenbank}
+
+Nachdem Sie das Paket nun in das Heimatverzeichnis des Nutzers auf das
+Zielsystem kopiert haben, entpacken Sie es mit folgenden Befehlen:
+
+\begin{lstlisting}
+    cd ~
+    tar xvfz flys-importer.tar.gz
+    cd flys-importer
+\end{lstlisting}
+
+Bevor die Importer verwendet werden können, ist es notwendig, dass eine leere
+Oracle Datenbank vorhanden ist. Anschließend müssen folgende SQL Skripte in
+diese Datenbank eingespielt werden:
+
+\begin{enumerate}
+\item oracle.sql \\
+In diesem SQL Skript befindet sich das Schema zum Speichern der hydrologischen
+Daten.
+
+\item oracle-minfo.sql \\
+In diesem SQL Skript befindet sich das Schema zum Speichern der morphologischen
+Daten.
+
+\item oracle-spatial.sql \\
+In diesem SQL Skript befindet sich das Schema zum Speichern der geodätischen
+Daten.
+
+\item oracle-spatial\_idx.sql \\
+Mittels diesem SQL Skript werden die Indizes zum geodätischen Datenbankschema\\
+hinzugefügt.
+
+\item import-dems.sql \\
+In diesem Skript sind Befehle zum Einfügen der digitalen Geländemodelle
+enthalten. Die Dateipfade in diesem Skript sind so anzupassen, dass sie auf die
+entsprechenden Geländemodelle im Dateisystem verweisen. Es ist notwendig die
+Pfade absolut anzugeben.
+
+\end{enumerate}
+
+Zum Einspielen dieser Schemata setzen Sie folgende Befehle auf der Kommandozeile
+ab. Beachten Sie, dass $sqlplus$ im Pfad liegen muss, und der Linux-Nutzer
+dies Kommando ausführen können muss. Außerdem sind $benutzername$ und $passwort$
+entsprechend Ihres Datenbank-Zugangs anzupassen.
+
+\begin{lstlisting}
+    sqlplus benutzername/passwort @schema/oracle.sql
+    sqlplus benutzername/passwort @schema/oracle-minfo.sql
+    sqlplus benutzername/passwort @schema/oracle-spatial.sql
+    sqlplus benutzername/passwort @schema/oracle-spatial_idx.sql
+    sqlplus benutzername/passwort @schema/import-dems.sql
+\end{lstlisting}

+ * <ul>
+ * <ol><b>gew.dir</b>: This property must point to the directory where all

+ * <ol><b>csv</b>: This property must point to the CSV file that contains the

+ * <ol><b>sql</b>: This property must point to a (not yet existing) file that
+ * will be generated by this converter.</ol>
+ * </ul>
+ * <br>
+ * In addiation, the following properties are accepted to modify log messages,
+ * etc.
+ * <ul>
+ * <ol><b>verbose</b>: Accepts integer values (0, 1, 2, 3) to modify the log
+ * messages. The higher the value the more log messages are printed to STDOUT.
+ * </ol>
+ * <ol><b>full</b>: Accepts true|false values. If true is set, all rivers

+	flys/issue409 (Überschwemmungsfläche: Reihenfolge in Themenliste nicht immer synchron mit Rendering)
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/FloodMap.java: Added
+	  a addLayer() method which should be used to add new layers to the map. New
+	  layers are always displayed at the bottom of the layer stack.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  Use FloodMap.addLayer() to add new layers instead of adding them directly
+	  to the Map.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapThemePanel.java:
+	  Removed the re-order process of map layers. This is no longer necessary,
+	  because MapOutputTab uses FloodMap.addLayer() to add new layers instead of
+	  adding new layers on its own using Map.addLayer() directly.

+
+	* src/main/java/de/intevation/flys/client/server/GCServiceImpl.java:
+	  Modified the constructor call of WMSLayer.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:

+	  information of the selected WMS layers for loading mechanisms.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapToolbar.java:

+	* src/main/java/de/intevation/flys/client/client/ui/map/MapThemePanel.java:
+	  Override getSingleContextMenu() to add a "zoom to layer" menu item which

+
+	* src/main/java/de/intevation/flys/client/client/widgets/tree/AttributedTreeNode.java:
+	  New. Subclassed TreeNode to carry the attribute data from
+	  the meta data service.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DatacageWindow.java:
+	  Create AttributedTreeNodes instead of TreeNodes to have the

+	  the data.
+
+2011-08-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

+
+2011-07-22  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/DefaultCollection.java,
+	  src/main/java/de/intevation/flys/client/shared/model/Collection.java:
+	  Collections are able to store the recommendations they have already
+	  loaded. Therefore, new methods have been added to add recommendations
+	  and to determine, if a recommendation has already been loaded.
+
+	* src/main/java/de/intevation/flys/client/server/DescribeCollectionServiceImpl.java:
+	  Read the already loaded recommendations from Collection's DESCRIBE
+	  document.
+
+	* src/main/java/de/intevation/flys/client/server/CollectionHelper.java:
+	  Write the Collection's recommendations into its attribute document.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Two things:
+	   1) Do no load recommendations that have already been loaded before.
+	   2) Update UI when there are no more artifacts to load (recommendations).
+
+2011-07-21  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/ArtifactDescriptionFactory.java:

+
+	* src/main/java/de/intevation/flys/client/shared/model/DefaultRecommendation.java,
+	  src/main/java/de/intevation/flys/client/shared/model/Recommendation.java:
+	  New. The interface and its default implementation that represent
+	  recommendations provided by an Artifact. A recommendation consists at
+	  least of the name of an ArtifactFactory and a list of database ids.
+
+	* src/main/java/de/intevation/flys/client/server/ArtifactDescriptionFactory.java:
+	  Read the recommendations from Artifact's DESCRIBE document (which
+	  structure has changed.)
+
+	* src/main/java/de/intevation/flys/client/shared/model/ArtifactDescription.java,
+	  src/main/java/de/intevation/flys/client/shared/model/DefaultArtifactDescription.java:
+	  Recommendation are no longer simple strings but Recommendation objects
+	  now. So, the interface to retrieve those recommendations has changed.
+
+	* src/main/java/de/intevation/flys/client/client/services/ArtifactServiceAsync.java,
+	  src/main/java/de/intevation/flys/client/client/services/ArtifactService.java,
+	  src/main/java/de/intevation/flys/client/server/ArtifactServiceImpl.java:
+	  This service takes a further string now, which represents the database

+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java,
+	  src/main/java/de/intevation/flys/client/client/ui/ParameterList.java,

+M      src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java
+
+2011-07-20  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/FloodMap.java: The
+	  vector layer which is used to save features created by the user acts as
+	  OpenLayers base layer. I decided to do so, because this is the first
+	  and only layer that will always exist in our maps. Users aren't able to
+	  remove it!
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapThemePanel.java:
+	  Added a callback interface that allows the MapOutputTab to react on
+	  modifications in the ThemePanel. This special callback is used to
+	  activate/deactivate layers.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  Now, the layers in the map reflect the facets of the map output. Each
+	  layer's extent is analyzed and finally the map is zoomed to the minimal
+	  extent that contains all layers.
+
+2011-07-20  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ThemeNavigationPanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/ThemeNavigationPanel.java:
+	  Moved the panel a package level higher.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ThemePanel.java: New.
+	  Abstract class that consists basically of the code that was removed from
+	  ChartThemePanel.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartThemePanel.java:
+	  Sourced code base out to ThemePanel, so that's possible to reuse the
+	  code for a MapThemePanel.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapThemePanel.java:
+	  New. A theme panel for the map widget.
+
+2011-07-19  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/AttributedTheme.java:
+	  New. This theme stores all its attributes in a map. The intent of this
+	  theme is to save all the facet's values contained in the DESCRIBE of the
+	  Collection to be able to write an equivalent attribute part as the
+	  incoming DESCRIBE has -> no loss of attributes like WMS URL or
+	  layernames in a map theme!
+
+	* src/main/java/de/intevation/flys/client/server/DescribeCollectionServiceImpl.java:
+	  Instantiate new AttributedThemes to save all information of a facet.
+
+	* src/main/java/de/intevation/flys/client/server/CollectionHelper.java:
+	  Write all attributes of an AttributedTheme into a facet's element.
+

+	  src/main/java/de/intevation/flys/client/client/ui/chart/ChartThemePanel.java:
+	  The 'active' member variable is an integer value now as it is in the
+	  Collection's DESCRIBE document, too.
+
+2011-07-18  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/services/ArtifactServiceAsync.java,
+	  src/main/java/de/intevation/flys/client/client/services/ArtifactService.java,
+	  src/main/java/de/intevation/flys/client/server/ArtifactServiceImpl.java:
+	  An artifact can be created using a UUID as model artifact.
+
+	* src/main/java/de/intevation/flys/client/server/ArtifactDescriptionFactory.java:
+	  Read artifact recommendations from artifact description.
+
+	* src/main/java/de/intevation/flys/client/shared/model/ArtifactDescription.java,
+	  src/main/java/de/intevation/flys/client/shared/model/DefaultArtifactDescription.java:

+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java,
+	  src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:
+	  Adapted the call of the ArtifactService.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  If the Artifact of a collection changes, the recommended Artifacts - if
+	  existing - are created and added to the current Collection.
+
+2011-07-12  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MeasureControl.java:
+	  New. This control consists of two OpenLayers controls to measure lines
+	  and polygons.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapToolbar.java:
+	  Added the MeasureControl.
+
+	* src/main/webapp/images/measurePolygon.png,
+	  src/main/webapp/images/measurePolygon_Selected.png,
+	  src/main/webapp/images/measureLine.png,

+
+2011-07-12  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapPositionPanel.java:
+	  New. This panel displays the mouse position in map coordinates.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/DrawControl.java::
+	  New. This control consists of a button to enable the control and a
+	  combobox that provides different types of barriers. Dependent on the
+	  selected barrier type, the user can draw lines or polygons into the map.
+
+	* src/main/java/de/intevation/flys/client/client/utils/EnableDisableCmd.java:
+	  New. This interface might be used to react on enable/disable operations.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapToolbar.java:
+	  Added controls to digitize lines and polygons.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/FloodMap.java:
+	  Added a method that returns a vector layer that might be used to insert
+	  new barriers draw by the user. This layer is used by the DrawControl.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  The MapToolbar requires a Canvas object now, which is used to keep track
+	  on the current mouse position.
+
+	* src/main/webapp/images/selectFeature_Selected.png,
+	  src/main/webapp/images/selectFeature.png,
+	  src/main/webapp/images/digitize.png,
+	  src/main/webapp/images/digitize_Selected.png,

+
+2011-07-11  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapToolbar.java:
+	  New. This toolbar provides controls that interact with the map.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/FloodMap.java:
+	  Removed the initialization of map controls.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  Added the MapToolbar at the top of the layout.
+
+2011-07-11  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  Finished layouting the components. The map has the same layout as the
+	  chart now.
+
+2011-07-08  Ingo Weinzierl <ingo@intevation.de>
+
+	* pom.xml: Added a dependency to GwtOpenLayers 0.5 (Apache 2.0).
+
+	* src/main/java/de/intevation/flys/client/FLYS.gwt.xml: Include the GWT
+	  OpenLayers code.
+
+	* src/main/webapp/FLYS.html: Include OpenLayers 2.9 (currently from remote
+	  openlayers.org server). For production use, we have to include a local
+	  OpenLayers.
+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java: Small
+	  modification on the way to render the HTML page. This lets us now
+	  combine GWT and SmartGWT components.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/FloodMap.java:
+	  New. This components manages the map provided by GwtOpenLayers.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  Initializes a FloodMap now and renders the map in the middle area. Note,
+	  that the layout is nearly completely using GWT components. Mixing
+	  GwtOpenLayers with SmartGWT doesn't work here.
+
+2011-07-08  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/OutputMode.java: An
+	  output mode has type member now. In addition, the interface describes a
+	  method that creates an OutputTab. Concrete subclasses should return
+	  OutputTabs that fit to their type.
+
+	* src/main/java/de/intevation/flys/client/shared/model/ChartMode.java:
+	  New. This OutputMode is instantiated if type == "chart" and creates
+	  ChartOutputTabs.
+
+	* src/main/java/de/intevation/flys/client/shared/model/MapMode.java: New.
+	  This OutputMode is instantiated if type == "map". It creates
+	  MapOutputTabs.
+
+	* src/main/java/de/intevation/flys/client/shared/model/DefaultOutputMode.java:
+	  This default implementation of an OutputMode support the type member
+	  now. The method to create OutputTabs will return null.
+
+	* src/main/java/de/intevation/flys/client/server/DescribeCollectionServiceImpl.java:
+	  Now, we support the 'type' attribute of Outputs in the DESCRIBE
+	  document. Based on the type, we will now instantiate concrete subclasses
+	  of the DefaultOutputMode. E.g. the type == 'chart', the instantiated
+	  OutputMode will be ChartMode.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  New. This OutputTab is used to render a map.
+
+	  Note: This is currently a stub only!
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Creating OutputTabs based on the names of an OutputMode is obsolete.
+	  Now, the OutputModes itself create their required OutputTab.
+
+2011-07-07  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,

+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.java:
+	  Added strings for the output mode 'floodmap'.
+
+2011-07-07  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/BooleanPanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/TextProvider.java,
+	  src/main/java/de/intevation/flys/client/client/ui/AutoIntegerPanel.java:
+	  Default values provided by the data list used to create the panels are
+	  set now.
+
+2011-07-07  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/DistancePanel.java:
+	  Refactored getting labels out to own methods which enables subclasses to
+	  changed them.
+
+	* src/main/java/de/intevation/flys/client/client/ui/WaterlevelGroundPanel.java:
+	  Override methods of DistancePanel to support own labels for this panel.
+	  In addition, this panel has no distance/locations table as the
+	  DistancePanel has.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_en.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.java: Added
+	  new strings for the distance panel and the waterlevel/ground panel.
+
+2011-07-07  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/BooleanPanel.java:
+	  This panel is a sublcass of TextProvider now. The difference to the
+	  TextProvider is, that there is the option to active/deactivate a
+	  checkbox. So, the valid values returned by this panel are "true" and
+	  "false".
+
+2011-07-07  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/TextProvider.java:
+	  Made methods in this class much smaller to override them easily in
+	  subclasses. In addition, the TextItem has been replaced with a
+	  DataSourceField which seems to be more easily to change in subclasses.
+
+	* src/main/java/de/intevation/flys/client/client/ui/AutoIntegerPanel.java:
+	  Override required methods of TextProvider. This panel now accepts
+	  integer values and the string "auto". An inner class
+	  AutoIntegerValidator is used to validate the user input.
+
+	* src/main/webapp/FLYS.css: Set style for html label elements. Those label
+	  elements are used in forms to label items.
+
+2011-07-06  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/event/ParameterChangeEvent.java:
+	  This event now supports a further member variable "type". Type is an
+	  enum and can be FORWARD or BACK which reflects to stepping forward or
+	  backward with the master artifact.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:
+	  Improved the way of adding/removing items to/from the static list of
+	  parameters. We now distinguish between the two ways:
+	  - step forward: the last item in the list is added to the static
+	                  parameter list. This makes redrawing much smoother.
+	  - step backward: only the necessary items are removed from the static
+	                   parameter list. Before, we have removed all items and
+	                   added the relevant ones afterwards. This makes
+	                   redrawing also much smoother.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ContinuePanel.java:
+	  This panel will have no static widget.
+
+	* src/main/java/de/intevation/flys/client/client/ui/AutoIntegerPanel.java:
+	  This panel uses the parents createOld() now.
+
+2011-07-06  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java,
+	  src/main/webapp/FLYS.css: Some layout improvements related to the height
+	  of components.
+
+2011-07-06  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:
+	  The right side of the ParameterList now consists of a stacked panel that
+	  itself consists of the helper panel and a panel for displaying the
+	  calculation results. The user is now able to see both at the same time.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Improved the Collection update process. There is no need to update the
+	  collection twice when the master artifact changed. Now, the collection
+	  is updated only a single time if the collection itself changed - and it
+	  changes everytime when its artifact is set.
+
+	* src/main/java/de/intevation/flys/client/client/ui/TableDataPanel.java:
+	  The label 'Berechnungsergebnisse' is no longer part of the Canvas
+	  created by this class.
+
+	* src/main/java/de/intevation/flys/client/client/ui/UIProvider.java,
+	  src/main/java/de/intevation/flys/client/client/ui/AbstractUIProvider.java:
+	  The helper panel is now a VLayout, no longer a Canvas.
+
+	* src/main/java/de/intevation/flys/client/client/ui/LocationDistancePanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/DistancePanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/MapSelection.java,
+	  src/main/java/de/intevation/flys/client/client/ui/WQInputPanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/SingleLocationPanel.java:
+	  Add helper widgets as members to the helper panel, no longer as
+	  children.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_en.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.java: Added
+	  strings for the input support stack.

+	* src/main/java/de/intevation/flys/client/client/ui/DoubleRangePanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/DistancePanel.java:
+	  Modified these classes with the intent to override them easier.
+
+	* src/main/java/de/intevation/flys/client/client/ui/BooleanPanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/DatacagePanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/TextProvider.java,
+	  src/main/java/de/intevation/flys/client/client/ui/AutoIntegerPanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/WaterlevelGroundPanel.java,
+	  src/main/java/de/intevation/flys/client/client/ui/DatacageButton.java:
+	  New panels for data input. The work on these classes is not finished
+	  yet!
+
+	* src/main/java/de/intevation/flys/client/client/ui/UIProviderFactory.java:
+	  Support more UI providers that return the new panels above.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.java: New
+	  strings used in the WaterlevelGroundPanel.
+
+2011-07-05  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/event/AdvanceHandler.java:
+	  New. This interface describes a handler that listens to events in order
+	  to advance to a next step.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ContinuePanel.java:
+	  New. This panel doesn't allow users to enter data. It only displays a
+	  link that lets users step forward to a next state.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:
+	  The ParameterList needs to take care on states that do not require user
+	  input but that aren't the final state of an artifact. In such case, the
+	  UI provider should be the ContinuePanel only! It allows users to step to
+	  the next state. In order to provide such functionality - step forward
+	  without feeding the artifact - the ParameterList now implements the
+	  AdvanceHandler.
+
+	* src/main/java/de/intevation/flys/client/client/ui/UIProviderFactory.java:
+	  If the uiprovider attribute is 'continue', the ContinuePanel is
+	  returned.
+
+	* src/main/java/de/intevation/flys/client/client/ui/SelectProvider.java:
+	  Adapted the width of the label field.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_en.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.java: Added
+	  strings for new states.
+
+2011-07-04  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/DistancePanel.java:
+	  Added the missing "back"-button.

+
+	flys/issue159 (WINFO: Radiobutton - Ortsauswahl bei "W für ungleichwertigen Abflusslängsschnitt" entfernen)
+
+	* src/main/java/de/intevation/flys/client/client/ui/DistancePanel.java:
+	  Connected columns of the locations and distances tables with the
+	  panels from/to fields. The first two columns of the locations and the
+	  first column of the distances table might be used to set from/to values
+	  in the panel.
+
+2011-07-01  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/DistanceInfoXML.java:
+	  New. This service - which is no GWT RPC Service - returns the distance
+	  info document as XML. The content of the document is not modified,
+	  parsed but only copied through.
+
+	* src/main/java/de/intevation/flys/client/client/ui/range/DistanceInfoDataSource.java:
+	  New. This data source is used to fill the LocationsTable and RangeTable.
+	  It uses the DistanceInfoXML service to query the required data
+	  automatically using a "locations" or "distances" filter to reduce the
+	  size of the data document.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DistancePanel.java:
+	  Use the DistanceInfoDataSource to fill the locations and distances tables.
+
+	* src/main/webapp/WEB-INF/web.xml: Registered the new service.
+
+2011-06-30  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/range/LocationsTable.java,
+	  src/main/java/de/intevation/flys/client/client/ui/range/RangeTable.java:
+	  New. These two tables are used to support the user to select from/to
+	  values in the distance panel.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DistancePanel.java:
+	  Added LocationsTable and RangeTable that currently load no data.
+
+2011-06-30  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/DistancePanel.java:
+	  New. This panel is used to insert kilometer ranges. There is no input
+	  mode for locations as it is in LocationDistancePanel.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants_en.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,

+	  Added i18n strings for the distance panel.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DoubleRangePanel.java:
+	  Added a method to set the step width.
+
+	* src/main/java/de/intevation/flys/client/client/ui/UIProviderFactory.java:
+	  Create a DistancePanel UIProvider if the "uiprovider" string in the
+	  DESCRIBE of an artifact equals "distance_panel".

+	  Create the chart image first before initialising listeners on it.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ZoomboxControl.java:
+	  The zoombox that is displayed in while zooming is 2 pixel smaller than
+	  the area between start and end point now. This should avoid the zoombox
+	  absorbing mouse events.

+
+2011-06-29  Ingo Weinzierl <ingo@intevation.de>
+
+	flys/issue181 (Erstes Thema in der Themenliste wählt sich automatisch wieder an)
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartThemePanel.java:
+	  We will no longer check if an update of the theme list is necessary.
+	  The EditEvent that is caught should be enough information to start the
+	  update process.

+	  flys/issue165 (Projektliste: Einige Auffälligkeiten nach Neuimplementierung)
+
+	* src/main/java/de/intevation/flys/client/client/ui/ProjectList.java:
+	  Set the maximal length of project names to 50 characters. If the name,
+	  entered by the user, is longer than this max value, it is not saved to
+	  artifact server and the old name is displayed again.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_en.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties,

+	  Added warning message for too long project names.
+
+2011-06-24  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  The "zoom-to-max-extent" button will have the effect that no zoom values
+	  are transfered to the server.
+
+2011-06-24  Ingo Weinzierl <ingo@intevation.de>
+
+	  flys/issue21 (Gleiches Projekt kann mehr als einmal gleichzeitig geöffnet werden)
+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java: Implements
+	  CollectionChangeHandler to lock new projects. In addition, there is a
+	  new method to close projects.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  If this view contains a Collection, FLYS is used to close this window.
+	  FLYS needs to unlock the project before the view is destroyed.
+	  Otherwise - if no Collection has been created yet - this view destroys
+	  itself.
+
+2011-06-23  Ingo Weinzierl <ingo@intevation.de>
+
+	  flys/issue170 (Diagramm: Initiales Zoomen zeigt verschobenen Bereich)
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  The chart image is no longer removed from DOM but it's source is set to
+	  a new value after the panel's size changes. This makes the zoom actions
+	  much smoother and there the initial zoom values are no longer broken.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/PanControl.java:
+	  Panning will now move the image itself but not its parent element.
+
+	* src/main/java/de/intevation/flys/client/shared/model/ChartInfo.java,
+	  src/main/java/de/intevation/flys/client/shared/Transform2D.java: Added

+	  Added more i18n strings for the project list and error messages.
+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java: Added a
+	  handler that catches uncaught exceptions. Those exceptions are displayed
+	  using a new method showWarning(Throwable t). This method brings up a
+	  Window that displays the stacktrace of the exceptions.
+
+2011-06-23	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* pom.xml: Added dependency to Apache Commons Lang 2.6 http://commons.apache.org/lang/

+	  might be used to validate user input.
+
+2011-06-22  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Register the CollectionView when a new collection is created. This is
+	  necessary to avoid an inconsistent view that would otherwise display
+	  projects that might have been deleted.
+
+2011-06-22  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/ProjectList.java:
+	  If an open project is removed (via context menu) the related
+	  CollectionView is removed from screen.
+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java: Added a method
+	  that returns the current FLYSWorkspace.

+2011-06-22  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/DoCollectionAction.java:
+	  New. This base RPC service implementation handles collecion specific

+	* src/main/java/de/intevation/flys/client/client/ui/ProjectList.java:
+	  Bugfix: If no user collections returned, we will clear the project list.
+
+2011-06-22  Ingo Weinzierl <ingo@intevation.de>

+
+	* src/main/java/de/intevation/flys/client/client/services/SetCollectionTTLServiceAsync.java,
+	  src/main/java/de/intevation/flys/client/client/services/SetCollectionTTLService.java,
+	  src/main/java/de/intevation/flys/client/server/SetCollectionTTLServiceImpl.java:

+
+	* src/main/java/de/intevation/flys/client/shared/model/DefaultCollection.java,
+	  src/main/java/de/intevation/flys/client/shared/model/Collection.java:

+	  Added a context menu item to rename the selected project and listeners
+	  to trigger setting 'name' and 'ttl' to a new value.
+
+	  TODO: We still need to write RPC services to update those values!
+
+2011-06-22  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties:
+	  Renamed the german translation of wq mode for "Q at gauge".
+
+	* src/main/java/de/intevation/flys/client/client/ui/WQInputPanel.java:
+	  Adapted the layout to fit the (long) german wq mode string.
+
+2011-06-22  Ingo Weinzierl <ingo@intevation.de>
+
+	  flys/issue104 (W-INFO: Wasserspiegellagenberechnung / Strecke)
+
+	* src/main/java/de/intevation/flys/client/client/ui/WQInputPanel.java:
+	  The old/static panel will display the selected wq mode now, because it's

+	  Build ReportModes for 'report' outs.
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:

+	  src/main/java/de/intevation/flys/client/shared/model/Collection.java:
+	  Adapted the constructor calls. They require a time-to-live attribute
+	  now. This value is retrievable via getTTL().
+
+	* src/main/java/de/intevation/flys/client/client/ui/ProjectList.java:
+	  The project list has now a column that displays an icon that shows the
+	  favorite state of the project. A gold star means, the project is marked
+	  as favorite, a silver one means that the project is no favorite project.
+
+	* src/main/java/de/intevation/flys/client/shared/model/CollectionRecord.java:
+	  The 'ttl' attribute returns the filename of the icon that should be
+	  displayed in the project list.
+
+	* src/main/webapp/images/star_silver.png,
+	  src/main/webapp/images/star_gold.png: New. These icons - based on icons
+	  copied from famfamfam - are used to mark a project as favorite or no
+	  favorite.
+
+2011-06-21	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/config.xml:
+	  Set project list update interval to 5 minutes. That is enough

+
+	  flys/issue22 (Abgelaufene Projekte/Collections werden noch in der Projektliste angezeigt.)
+
+	* src/main/java/de/intevation/flys/client/client/Config.java,
+	  src/main/java/de/intevation/flys/client/client/config.xml:
+	  Added a config option to specify the update interval of the project
+	  list. This value is retrievable using the method
+	  Config.getProjectListUpdateInterval().
+
+	* src/main/java/de/intevation/flys/client/client/ui/ProjectList.java:
+	  Added a timer to update the user's collections frequently. The interval
+	  is determined by the constant UPDATE_INTERVAL which is currently 30
+	  seconds or a config.xml option that needs to be configured at
+	  "/config/projectlist/update-interval/text()".

+
+	* src/main/java/de/intevation/flys/client/client/ui/wq/QDTable.java:
+	  New. This table is used to show Q and D values for the WQInputPanel. The
+	  first two rows are selectable icons.
+
+	* src/main/java/de/intevation/flys/client/client/ui/wq/WTable.java: New.
+	  This table is used to show W values for the WQInputPanel. The rows in
+	  this table are not selectable.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DoubleRangePanel.java:
+	  Added methods to set the lower and upper value directly.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DoubleArrayPanel.java:
+	  Added a method to add a further double value to the current list.
+
+	* src/main/java/de/intevation/flys/client/client/ui/WQInputPanel.java:
+	  Removed the old WQD tables and replaced them with a QDTable and a
+	  WTable. The WQD values are sorted into the two tables when they are
+	  initialized. The values in the WTable are not selectable. The QDTable
+	  has two selectable columns. Based on the current mode (single values or
+	  range mode), the selected values are filled into the array panel or into
+	  the range panel.

+
+	  flys/issue118 (W-INFO: Eingabe Q aus Auswahlunterstützung und Manuell)
+
+	* src/main/java/de/intevation/flys/client/client/ui/WQInputPanel.java:
+	  Added a further radio button to select a "Q at Gauge". In addition, this
+	  panel returns a new value "wq_free" that depends on the selected Q mode.
+	  It is "true" if Q is selected, otherwise "false".
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,

+	  getIndex() method.
+
+2011-06-17  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/DescribeCollectionServiceImpl.java:
+	  Read "index" and "description" of facets from collection's describe
+	  document. In addition, I replaced the expensive XPath search for
+	  attributes with DOM methods.

+	  src/main/java/de/intevation/flys/client/shared/model/DefaultTheme.java,
+	  src/main/java/de/intevation/flys/client/shared/model/DefaultFacet.java:
+	  Themes and facets have now indices and descriptions.
+
+	* src/main/java/de/intevation/flys/client/shared/model/FacetRecord.java:
+	  Display the description of a theme in the theme panel instead of the
+	  name (which represents the facet type).
+
+2011-06-16	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/DatacageWindow.java:
+	  Alloc TreeNode array with the right size because its known.
+
+2011-06-15  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/DoubleArrayPanel.java:
+	  Be more tolerant with entered whitespaces.
+
+2011-06-15  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/ParameterList.java:
+	  Set height of the parameter panel that shows the "old" values to "1" if
+	  no "old" value is existing. This avoids GWT throwing warning messages.

+
+2011-06-14  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties:
+	  Adapted the german error message that is displayed if the user entered a
+	  value which is not in the valid range.
+
+2011-06-14  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/WQDataItem.java:
+	  New. This DataItem is used to save min/max W/Q values. This enables the
+	  UIProvider to validate the entered values. Currently, this is used in the
+	  WQAdaptedInputPanel only.
+
+	* src/main/java/de/intevation/flys/client/server/ArtifactDescriptionFactory.java:
+	  Read the W/Q ranges from DESCRIBE document and create WQDataItems if
+	  they are existing.
+
+	* src/main/java/de/intevation/flys/client/client/ui/WQAdaptedInputPanel.java:
+	  Introduced a client side input validation for the entered W/Q values
+	  with respect on their format and min/max range.
+
+2011-06-14  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/WQInputPanel.java: The
+	  values entered by the user are validated on client side now taking
+	  account on the format and the river's W/Q ranges.
+
+2011-06-14  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/DoubleArrayPanel.java:
+	  Added a method to validate the form field. If a value is not a valid
+	  double value, it returns false.
+
+	* src/main/java/de/intevation/flys/client/client/ui/SingleLocationPanel.java:
+	  The values entered in the text field are validated regarding to the
+	  river's range.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_en.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.java: Added

+
+2011-06-09  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,

+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.java:
+	  Added error strings for the range range/location panel.
+
+	* src/main/java/de/intevation/flys/client/client/ui/AbstractUIProvider.java:
+	  Added a validate() method that is called before the event to step
+	  forward is fired. If the method returns a list with errors, the event is
+	  not fired. In that case, an error dialog is displayed.
+
+	* src/main/java/de/intevation/flys/client/client/ui/LocationDistancePanel.java:
+	  Override the validate() method of AbstractUIProvider.
+
+	* src/main/java/de/intevation/flys/client/client/ui/DoubleRangePanel.java:
+	  Added a method that validates the form.
+
+2011-06-09  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/ChartInfoServiceImpl.java:
+	  Parse min/max values for axes and all transformation matrix elements.
+
+	* src/main/java/de/intevation/flys/client/shared/model/Axis.java: An axis
+	  has a min and max value now.
+
+	* src/main/java/de/intevation/flys/client/shared/model/ChartInfo.java:
+	  The ChartInfo object provides a Transform2D object for each y axis
+	  contained in the chart.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  Refactored the zoom and pan actions. The values used to select a
+	  concrete clip of the chart are computed based on the min/max range of an
+	  axis. The chart request uses percentual values for axes ranges now.
+
+2011-06-09  Ingo Weinzierl <ingo@intevation.de>
+
+	  flys/issue139 (WINFO: NPE bei Step-Back bei ungleichwertiger Berechnungsart)

+2011-06-08  Ingo Weinzierl <ingo@intevation.de>
+
+	  flys/issue21 (Gleiches Projekt kann mehr als einmal gleichzeitig
+	  geöffnet werden)
+
+	* src/main/java/de/intevation/flys/client/client/FLYS.java: Introduced a
+	  lock mechanism for projects. When a project is opened, it becomes
+	  locked. Further clicks on that project in the project list will have no
+	  effect except it brings up the project window.
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:
+	  Implements the CloseClickHandler interface now. The operations triggered
+	  by the "x" in the upper right corner of the window will close and
+	  destroy the window. This has been done automatically before.
+
+	* src/main/java/de/intevation/flys/client/client/ui/FLYSWorkspace.java:
+	  Added a new method that brings up a project window.
+
+2011-06-08  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/ChartInfoServiceImpl.java:
+	  Skip axes that lay out of valid bounds. E.g. there are 2 axes: if one of
+	  those axes position is > 1 it is skipped.
+
+2011-06-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  Don't crash if there is no transformer.
+
+2011-06-08  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/ProjectList.java:
+	  Added a dirty hack to accept project names shorter than 30 characters
+	  without cutting a part from the middle.
+
+2011-06-07  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/PanControl.java:
+	  Implemented the onMouseOut() method. If this event is catched, the
+	  current pan operation is finished (not canceled).
+
+2011-06-07  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/Axis.java: New.
+	  This class should represent an axis in a chart.
+
+	* src/main/java/de/intevation/flys/client/shared/model/ChartInfo.java:
+	  New. This class is used by the ChartInfoService to retrieve more
+	  information about a Chart that just the Transform2D object to reproject
+	  points. It currently stores x and y axes and the Transform2D object of a
+	  chart.
+
+	* src/main/java/de/intevation/flys/client/client/services/ChartInfoServiceAsync.java,
+	  src/main/java/de/intevation/flys/client/server/ChartInfoServiceImpl.java,
+	  src/main/java/de/intevation/flys/client/client/services/ChartInfoService.java:
+	  Changed the return value of this service from Transform2D to ChartInfo.
+	  The Transform2D object is included in this new ChartInfo.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  Implements the PanHandler interface. If a PanEvent is fired by the
+	  PanControl, a new chart range is computed using the axes information
+	  provided by the ChartInfo object (that has been retrieved by the
+	  ChartInfoService).
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartToolbar.java:
+	  Added the PanControl to the toolbar.
+
+2011-06-07  Ingo Weinzierl <ingo@intevation.de>

+	  src/main/java/de/intevation/flys/client/client/event/PanHandler.java:
+	  New. Classes and interfaces necessary for a pan listeners mechanism.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/PanControl.java:
+	  New. A control that enables the user to pan a chart.
+
+	* src/main/webapp/images/pan.png,
+	  src/main/webapp/images/pan_Selected.png: Icons for the PanControl.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants_en.properties,

+
+	* src/main/java/de/intevation/flys/client/client/services/CSVExportServiceAsync.java,
+	  src/main/java/de/intevation/flys/client/client/services/CSVExportService.java,
+	  src/main/java/de/intevation/flys/client/server/CSVExportServiceImpl.java:
+	  Changed the return value of this service from List to List<String[]>.
+	  This helps GWT creating JavaScript objects.
+
+	* src/main/java/de/intevation/flys/client/client/ui/TableDataPanel.java:
+	  Adjusted the return value of the CSVExportService and added a warning
+	  dialog if an error occured while fetching those data.
+
+2011-06-07  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/ChartServiceHelper.java:

+	* src/main/java/de/intevation/flys/client/server/ChartOutputServiceImpl.java:
+	  Removed the code to create the chart attribute document. This work is
+	  done in the ChartServiceHelper.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  Added a method that returns all attribute that should be used for the
+	  chart creation. Currently, there are width, height, x and y ranges.
+
+2011-06-06  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  Repaired broken zoom-out control. We will now zoom out for 10% of the
+	  axis range. E.g. range before = 2 - 10 , range after = 1.2 - 10.8
+
+2011-06-06  Ingo Weinzierl <ingo@intevation.de>
+
+	  flys/issue131 (Anzeige der Position bei großen Zahlen ungenau)
+
+	* src/main/java/de/intevation/flys/client/server/ChartInfoServiceImpl.java:
+	  Repaired a broken XPath expression for the chart attributes.
+
+2011-06-06  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ZoomboxControl.java:
+	  Added a handler that listens to mouse out events. If the mouse moves out
+	  of the chart area, the current zoom operation is canceled. The zoombox
+	  and the coordinates are reset.
+
+2011-06-03  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  Added a method that allows zooming out for a specified factor (between
+	  0-100).
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartToolbar.java:
+	  Added a button to zoom out 10%.
+
+	* src/main/java/de/intevation/flys/client/client/FLYSConstants.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_en.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants_de.properties,
+	  src/main/java/de/intevation/flys/client/client/FLYSConstants.java:
+
+	* src/main/webapp/images/zoom-out.png: New. The icon for the zoom-out
+	  control.
+
+2011-06-03  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  New method to reset the zoom.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartToolbar.java:
+	  Added a button that resets the zoom and triggers an update of the chart.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ZoomboxControl.java:
+	  This control inherits from ImgButton now. The icon displayed for this
+	  control is the same as in the desktop version of this software.

+
+	* src/main/java/de/intevation/flys/client/server/ChartOutputServiceImpl.java:
+	  Append the selected min and max ranges for x and y axes to the attribute
+	  document. This enables the server to zoom the chart to the specified
+	  view.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  The x and y ranges specified after zooming are stored as instance
+	  variables and used while creating the chart imgage url. The
+	  ChartOutputService will put those ranges into the attribute document for
+	  the chart creation.
+
+2011-06-01  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  Implements the ZoomHandler interface now. Currently, the values are just
+	  received from ZoomboxControl. We still need to refresh the chart with
+	  those zoom values.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartToolbar.java:
+	  Registered the ChartOutputTab as ZoomHandler at the ZoomboxControl.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ZoomboxControl.java:
+	  Bugfix: fire the ZoomEvent when mouse up events occur. The events was

+	  New. A zoombox control that draws - if activated - an semi opaque
+	  rectangle on the top of the observed panel. This control uses mouse
+	  up/down/move events to draw the rectangle. A mouse down event starts the
+	  zoom process, a mouse up event determines the coordinates for the zoom
+	  and fires a ZoomEvent.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartToolbar.java:
+	  Added the ZoomboxControl.
+
+2011-06-01  Ingo Weinzierl <ingo@intevation.de>

+	  now. The components inside this panel have also fixed width values.
+
+2011-06-01  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  After the chart panel is resized, we will now fetch a chart info
+	  document using the ChartInfoService. This service lets us update the
+	  current Transform2D - which is used to display mouse position in chart
+	  coordinates and determine mouse clicks for zooming.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartToolbar.java:
+	  Changed the constructor call of the MousePositionPanel. It needs to
+	  ChartOutputTab now.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/MousePositionPanel.java:
+	  Changed the way to compute the chart coordinates. We will now use the
+	  Transform2D object that is returned by the ChartInfoService.
+
+2011-06-01  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/client/ui/CollectionView.java:

+	  Added the MousePositionPanel.
+
+	  NOTE: The MousePositionPanel does NOT show the correct position and it
+	  does NOT show the x|y coordinates in chart dimension yet!
+
+2011-05-27  Ingo Weinzierl <ingo@intevation.de>
+

+	  changes.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartThemePanel.java:
+	  Implements the OutputParameterChangeHandler interface. After the output
+	  parameter of the chart have changed, the chart is refreshed.
+
+	  NOTE: The panel is disabled right before the RPC call to replace the
+	  collection's attribute is executed. It is enabled after the RPC call has
+	  finished.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartOutputTab.java:
+	  Implements the HasOutputParameterChangeHanders interface. The event is
+	  fired if there are changes in the chart theme control panel.
+
+2011-05-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/server/CollectionAttributeServiceImpl.java:

+	  Collection will be stored in the artifact database now.
+
+	* src/main/java/de/intevation/flys/client/server/CollectionHelper.java:
+	  New. This helper is currently used to create the attribute document of a
+	  collection based on a Collection itself. This helper now takes the
+	  attributes of the Collection and transforms those values into XML.
+
+2011-05-27  Ingo Weinzierl <ingo@intevation.de>
+
+	* src/main/java/de/intevation/flys/client/shared/model/Theme.java,

+	  New. This service should be used to modify/update the attribute of a
+	  collection.
+
+	  NOTE: The update process needs to be implemented! Currently, the only
+	  thing this service does is, that is waits 5sec and fetches a new
+	  description right after this ;-)
+
+	* src/main/java/de/intevation/flys/client/shared/model/ThemeList.java:
+	  Added methods to remove and add themes.
+
+	* src/main/java/de/intevation/flys/client/client/ui/chart/ChartThemePanel.java:

+	  artifact this theme belongs to.
+
+	* src/main/java/de/intevation/flys/client/shared/model/ThemeList.java:
+	  New. A ThemeList is a wrapper for themes and should provide some

+2011-09-19  RELEASE 2.5
+
+    NEW:
+
+        * Added new widgets:
+          - DistancePanel: allows users to enter a km range.
+          - ContinuePanel: offers a 'next' button only for states which do not require input data.
+          - BooleanPanel: allows users to answer for yes/no questions.
+          - TextProvider: allows users to enter text strings.
+          - AutoIntegerPanel: allows users to enter integer values or the value 'auto'.
+          - WaterlevelGroundPanel: allows users to enter three integer values for "from", "to", and "diff" used for floodmaps.
+          - DatacagePanel: displays a datacage widget, that allows users to select items from datacage.
+          - MapPanel: displays a Gwt-OpenLayers based map and a MapToolbar.
+          - DatacageWidget: reads XML documents from MetaDataService and displays the result as tree.
+          - DigitizePanel: allows users to digitize spatial geometries using a map based on Gwt-OpenLayers.
+          - DatacageTwinPanel: allows users to select items from two parallel datacage widgets.
+
+        * Added RPC services to:
+          - create new Artifacts based on a model Artifact (ArtifactService).
+          - read XML documents from MetaDataService (MetaDataService).
+          - read map information (as srid, extent) from MapInfoService (MapInfoService).
+          - feed an Artifact only (without forwarding into a new state) (FeedService).
+          - fetch the description of an Artifact only (DescribeArtifactService).
+          - create new Artifacts based on Recommendation objects and add them to
+            current Collection (LoadArtifactService).
+
+        * The DatacageWindow in charts now allows adding new themes to charts.
+
+        * Introduced a Recommendation mechanism in the CollectionView that loads Artifacts to the
+          current Collection based on the recommendations in the Artifact description of the master
+          Artifact.
+
+        * Extract background state/messages of master Artifacts. Lock CollectionView window if
+          master Artifacts have started background threads that have not finished yet and display
+          status messages in the lock screen.

+          The layers added to the map depend on the facets of the output.
+
+        * Added a CrossSectionChartThemePanel. This ThemePanel offers a spinner right besides the
+          theme name to modify the current km.
+
+        * Added a MapToolbar that offers controls for working with a map based on Gwt-OpenLayers.
+
+        * UI improvements:
+          - Stepping back/forward in parameterization no longer redraws the whole CollectionView.
+          - set the title of CollectionView windows when the name of a collection is modified in the project list.
+          - introduced "find-as-you-type" search in most input tables.
+
+        * Distinguish between 'chart' and 'map' output modes to create ChartOutputTabs or MapOutputTabs.
+
+        * Bumped GWT up to 2.3.0.

+2011-09-19  Release V 2.5.0
+
+== Version 2.5.0 (19.09.2011, rev. 2786) ==
+
+Diese Seite stellt primär Neuerungen in dieser Version aus Sicht des Nutzers zusammen bzw. verweist auf Vorarbeiten, die für jeweilige Funktionen benötigt werden.
+
+=== Zusammenfassung und Hintergedanken zur Version ===
+Die Version 2.5 verfolgt die folgenden Ziele auf den unterschiedlichen Ebenen:
+ * Bestehende textbasierte Daten von FLYS für die Gewässer Saar, Mosel und Elbe über Importmechanismen vollständig in die Datenbankhaltung samt dazugehörigen Datenmodell übernehmen
+ * Strukturierung von Geodaten und Import dieser in die Datenhaltung
+ * den Datenkorb als zentralen Datenmanager für statische und dynamische Daten bereitzustellen und in den unterschiedlichen Anwendungskontexten -- inline: Parameterisierung Überschwemmungsfläche, Parameterisierung Differenzen und als externes Fenster: Zuladen manueller Daten -- zugreifbar zu machen
+ * die Karte als Auswahlunterstützung und zur Anzeige von gerechneten Überschwemmungsflächen bereitzustellen
+ * die Integrationsfähigkeit der Karte in die Projektverwaltung zu ermöglichen
+ * Integration und Ansteuerung von WSPLGEN als asynchronen Prozeß in einer Mehrbenutzerumgebung zu integrieren
+ * Infrastruktur zur Ansteuerung und Generierung von Karten bereitzustellen
+ * die Projektverwaltung abzuschließen, um die Gesamtarbeitsweise im System greifbar zu machen.
+ * die Anwendung auf seine Zieldatendank Oracle 11 zu bringen
+ * das Gesamtsystem in seiner Zielumgebung SLES 11 bereitzustellen
+ * Erste Erfahrungsmöglichkeit mit FLYS togo bereitzustellen
+ 
+=== Framework ===
+
+ * Allgemeine Steuerung
+
+ * Projektverwaltung
+  * Projekte umbenennen
+  * Projekte dublizieren
+  * Titel der Projekte nach Umbenennung in jeweiligem Projektfenster anzeigen
+  * Filterung der Projekteliste auf Basis der Titel
+
+
+=== Fachdatenbestand ===
+
+ * Datenmodell
+  * Erweiterung um hyk-Datenbestand
+  * Erweiterung im Querprofildatenbestand

+
+=== WINFO ===
+
+ * Gewässer- und Pegelinfos
+  * Einführung einer sog. Ziehharmonika, um Pegelinfos fortwährend integrieren zu können.
+ * Wahl von Strecke und Ort
+  * Filterung auf Streckenfavoriten und Orten durch Eingabe eines Begriffes - [[https://roundup-intern.intevation.de/flys/issue141|Details]]
+ * Wahl von Abflüssen, Wasserständen und Dauerzahlen
+  * Bei Wasserspiegellagenberechnungen können Qs nur noch angezeigt werden, wenn eine Berechnung auf freier Strecke gestartet wird.
+
+ * Berechnungsausgabe
+  * Wasserspiegellagen
+   * Querprofile
+    * Darstellung der Querprofildatensätze aus der Datenbank
+    * Manuelle Eingabe von Kilometern
+     * Zur Zeit sind noch folgende Aspekte limitiert:
+      * Anzeige einer Wasserspiegellage und eines Querprofildatensatzes
+      * Durchlaufen des Kilometerzählers in 5 km Schritten
+      * kein synchrones bzw. asynchrones Navigieren möglich
+   
+   * Längsschnitt
+    * Anzeige von Streckenfavoriten
+    * Manuelles Hinzuladen früherer Berechnungen
+
+  * Abflusskurven
+   * Automatisches Anzeigen von Hauptwerten aufgrund einer Vorbelegung
+   * Datenkorb: Exemplarische Darstellung des Gesamtbestandes von früheren und datenbankbasierten Inhalten
+
+  * Überschwemmungsfläche (aufgrund zu wenig strukturierter Geodaten kann dies erstmalig an der Saar getestet werden!)
+   * Parameterisierung:
+    * Zugriff auf beliebige Wasserspiegellagen
+    * Auswahl eines beliebigen digitalen Geländemodells am Gewässer
+    * Digitalisierung von Rohren, Gräben und Dämmen
+    * Löschen bestehender Rohren, Gräben und Dämmen
+    * TODO: Berücksichtigen einer eigenen Shapedatei bei Berechnungstyp "Szenario"
+   * Durchführung der Berechnung:
+    * Informieren des Nutzers zum Fortgang der Berechnung
+     * TODO: Abbrechen der Berechnung
+    * Während der Berechnung kann das Projekt geschlossen werden und zu einem beliebigen Zeitpunkt wieder geöffnet werden. Der jeweilige Status wird dem Nutzer angezeigt.
+   * Technik/Hintergrund

+== Version 2.4.0 (27.06.2011, rev. 2257) ==
+
+Diese Seite stellt primär Neuerungen in dieser Version aus Sicht des Nutzers zusammen bzw. verweist auf Vorarbeiten, die für jeweilige Funktionen benötigt werden.
+
+=== Zusammenfassung und Hintergedanken zur Version ===
+Die Version 2.4 verfolgt für WINFO das Ziel die fachliche Nachprüfbarkeit der bestehenden Berechnungsarten bereitzustellen. Hierbei sind folgende Aspekte wichtig:
+ * fachliche Richtigkeit und Genauigkeit der bestehenden Berechnungsarten
+ * Bereitstellung und Unterstützung eines Berichtswesens in den Berechnungsvorgängen
+ * Vorbereitung der Berechnungsarten für den Mehrbenutzerbetrieb
+ * Vollständigkeit der benötigten Fachdaten aus dem FLYS-Datei-Server für bestehende Funktionen (Kantenbilder, Typisierung Streckenfavoriten)
+ * Export aller benötigten Berechnungsdaten in entsprechenden Formaten (WST, WST korrigiert, CSV, AT)
+
+Um diese Ergebnisse visualisieren und im konsolidierten Diagrammbereich testen zu können, stellt das Diagramm die zentralen interaktiven Funktionen zur Navigation und Themensteuerung bereit und prüft die Kopplung von Client und Server Zusammenspiel. Um dem Nutzer die Verbindung seines Gesamtworkflows zu ermöglichen, ist die Projektverwaltung mit interaktiven Funktionen ausgestattet worden. Diese setzt unterschiedliche Parameterisierungen und Darstellungen in Projekten in Zusammenhang.

+
+2011-05-16  Release V 2.3.0
+
+=== Framework ===
+
+ * Projektverwaltung (Pflichtenheft Kap. 3.3, Lokale Daten > Arbeitssitzungen)
+  * Mit dem Anlegen eines neuen Projektes wird die Projektliste automatisch gefüllt.
+   * Zu beachten: Zur Zeit operiert das System noch mit '''einem''' Benutzer, so dass jeder alle auf dem Server liegenden Projekte sieht. Mit der Einführung einer Nutzeranmeldung sieht dann jeder Nutzer nur noch seine eigenen Projekte.
+  * Mit einem Doppelklick oder das Kontextmenü können die jeweiligen Projekte wieder geöffnet werden. Sie stellen den Arbeitszustand des letzten "Übernehmen" wieder her. Die Einstellung ist sprachunabhängig, d.h. auch wenn zuvor Diagramme in deutsch erstellt worden sind, können diese in englischer Sprache geöffnet und dargestellt werden.
+   * Projekte können Projekte noch in mehreren Fenster geöffnet werden. Um Konsistenz herzustellen, kann man ein Projekt nur einmal öffnen. (vgl. https://roundup-intern.intevation.de/flys/issue21)
+  * Neue Fenster überlappen sich nicht mit der Position des vorherigen Fensters, um beim Anlegen eines neuen Projektes eine vollständige Überdeckung zu vermeiden
+   * Projektfenster maximieren (vgl. https://roundup-intern.intevation.de/flys/issue35)
+
+ * Projekteinstieg
+  * Klick-Optimierung der Gewässerauswahl über eine Liste: von 3 Klicks zu 1 Klick.
+
+ * Internationalisierung (Pflichtenheft, Kap.4.3.4)
+  * Beim Start wird die Spracheinstellung des Browser automatisch ausgewertet und die dazugehörige Oberfläche in deutsch oder englisch geladen. Wenn eine andere Sprache als deutsch oder englisch angefragt wird, fällt die Anwendung auf englisch (TOCHECK) zurück.
+  * Die Sprache kann jeweils manuell gewechselt werden. Dies hat Auswirkungen auf die Bedienoberfläche, Diagramme und Nutzung von Dezimaltrenner und Punkt
+
+=== Fachdatenbestand ===
+ * Import der hydrologischen Daten der Elbe
