"""
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
