[Gimp-docs] ugly hack to update old PO files

[Daniel Nylander]

Did some ugly hacking today to update my old PO files with new strings
from the recent POT files and re-using my already translated strings..
This is rather ugly but useful.. just wanted to share this with you guys

cd po/xx # where xx is your language code

pocompendium Compendium.po -d .

# translate/review/edit your Compendium.po file

for a in `find .|grep po$`; do echo $a; msgmerge
--compendium=Compendium.po -U $a ../../pot/$a*; done

# That will update your PO files with strings from the compendium.. i.e
translate one string one time
