Hi,
I wrote a small thingy to help in translating RoundCube. This is not intended to be added to RoundCube, just a little helpful tool.
Place the attached translate.php in ./program/localization, and point your browser to '<your-RC-URL>/program/localization/translate.php?language=<your-language>' .
Example in my case:
http://eddy.introweb.nl/roundcubemail/program/localization/translate.php?lan...
The output is copy&pasteable to the files labels.inc and messages.inc, and untranslated labels and messages will show in red.
