+If you want your app to run under MacOS X with internationlization as
+described above you'll need to make one modification to the Info.plist
+file which describes the contents of the "application bundle". This
+file (an XML text file in UTF-8 format) should have a
+CFBundleDevelopmentRegion entry describing the language of the developer
+- mostly English - and normally MacOS X will query the bundle for the
+presence of certain resource directories to find out which languages
+are supported (e.g. the directory German.lproj for German). 
+Since wxWidgets based applications don't use these directories
+for storing resource information (they store the translation in the
+mo files instead) the application needs to be told explicitly which
+langauges are supported. This is done by adding a CFBundleLocalizations
+entry to Info.plist. This can look like this:
+
+\begin{verbatim}
+	<key>CFBundleDevelopmentRegion</key>
+	<string>English</string>
