Always save a symbol set, use the mapfile name as prefix for the symbol set and use the mapfile path to save the symbol set.

Restrictions

Currently there are some restrictions in the usage of the converter:

Supported datasources:

 * ArcSDE-passwords cannot be read since they are encrypted. The converter
   exports the string "define me" which needs to be replaced later on in the
   resulting mapfile

 * Since the MapServer cannot use a file geodatabase datasource the converter
   does not support this datasource and will not transform the MXD-file at all.

 * Raster data is not supported by the converter yet.

Symbol support:

 * Line symbols with pattern cannot be combined with marker symbols. The
   converter reads all symbols and writes the corresponding styles to the
   resulting mapfile but the marker symbols are rendered without any gap.

   * Workarround:
     For small marker symbols it is recommended to use a line symbol in
     combination with pattern (in ArcGIS called template) to create the
     symbology.
     The reason why marker symbols cannot be used in combination with a template
     is the difficulty to interpret the read attributes like marks and gaps and
     write the appropriate symbols with the appropiate gap to the mapfile.

 * The converter sets the width to 1 for line symbols that have a width
   smaller than 1. Outlines with a width smaller than 1 are drawn in the fill
   color of the ploygon and the width is set to 1.

   * Tip:
     To avoid lines and line colors (specially outlines) to be handled by the
     converter, use integer numbers for line width only.

 * Picture symbols are not supported by the converter.

 * In ArcGIS maps default symbols can be defined as fallback. Since MapServer
   does not support such fallback symbols or styles the converter does not
   read these default symbols.

 * In ArcGIS predefined symbols like bars or pie charts can be used to display
   values. The converter does not support these symbols.

Layer support:

 * Grouplayer with more than  one group level are not supported by the MapServer
   and even not by the converter.
