"""
A script, together with i18n2.py, to ease the use of the gettext translation
system with larch. Just run it with the (short) name of your language,
e.g. "fr", as argument.
The steps it performs are roughly given below. If you prefer a gui have a
look at poedit (uses wxwidgets).
1) Generally something like: pygettext.py -p i18n -o larch.pot *.py
2) cd i18n ; msginit -i larchin.pot -l de
OR:
2a) to update a po file:
cd i18n ; msgmerge -U larchin.po larchin.pot
3) edit po file
4) generate binary file:
cd i18n ; msgfmt -c -v -o larchin.mo larchin.po
5) move the .mo file to i18n/de/LC_MESSAGES
6) Add to the main program file:
import gettext
gettext.install('larch', 'i18n', unicode=1)
5) Run, e.g.:
LANG=de_DE larchin.py
