The intltool collection can be used to do these things:

 o Extract translatable strings from various source files (.xml.in,
   .glade, .desktop.in, .server.in, .oaf.in).

 o Collect the extracted strings together with messages from traditional
   source files (.c, .h) in po/$(PACKAGE).pot.

 o Merge back the translations from .po files into .xml, .desktop and
   .oaf files.  This merge step will happen at build resp. installation
   time.
