+1) Generally something like: pygettext.py -p i18n -o liblarch.pot *.py
+
+I think poedit can do most of the processing, but the steps are:
+
+2) cd i18n ; msginit -i liblarch.pot -l de
+
+OR:
+2a) to update a po file:
+
+cd i18n ; msgmerge -U liblarch.po liblarch.pot
+
+3) edit po file
+
+4) generate binary file:
+cd i18n ; msgfmt -c -v -o liblarch.mo liblarch.po
+
+5) move the .mo file to i18n/de/LC_MESSAGES
