 First of all, thank you for helping translating SàT :)
 
+NOTE: *.po files are in i18n directory

 To translate a file, you can use a dedicated tool as the excellent gtranslator:
 - use the template .po file (e.g. sat.po) and name it to your translated language (e.g. fr.po for french); you can preferably generate a new template directly from the source with the following command (eventually adapted):
 > xgettext -L python -d sat sat.tac tools/*py plugins/*py
