GMOCCAPY can be localized very easy, because the corresponding files are separated from the linuxcnc.po files, so there is no need to translate unneeded stuff. The files are placed in /src/po/gmoccapy. Just copy the gmoccapy.pot file to something like fr.po and translate that file with gtranslator or poedit. After a make you got the GUI in your preference language. Please publish your translation, so it can be included in the official packages and be published to other users.
At the Moment it is available in English, German, Spanish, Polish, Serbian and Hungarian. Feel free to help me to introduce more languages,
