+
+	* getan/config.py: Setup the language.
+
+	* getan/resources.py: New module that should serve functions for working
+	  with resources. Currently, there is just a single function to get a
+	  translated text based on gettext.
+
+	* getan/states.py,
+	  getan/view.py: Replaced hard coded texts with gettext calls.
+
+	* po/Makefile,
+	  po/README,
+	  po/de.po: Makefile, description and german translation for gettext.
+
+	  NOTE: It is necessary to call 'make mo' in the po directory to enable the
+	  german language.

+Getan Message Translations
+==============================
+
+The message catalogs are managed with the following software:
+
+ - pygettext (usually distributed with Python)
+
+ - GNU gettext (msgmerge and msgfmt)
+
+
+Common tasks:
+
+ - Create/Update getan.pot-File when the sources were edited and
+   messages have been added or changed and after a fresh checkout
+
+     $ make pot
+
+ - When the getan.pot has been changed, run
+
+     $ make merge
+
+   to merge the changes in the pot file with the messages already in the
+   *.po files.
+
+ - When the translations in the po files have been changed, run
+
+     $ make mo
+
+   to generate new .mo files under ../share/locale
+
+ - The make mo command prints statistics about the translations.  To get
+   a less verbose version use this:
+
+     $ make stat
