Translation
Luma supports a number of languages already, all of them being maintained by a team of developers and translators. There's a separate mailinglist for those interested in doing translation-work on Luma.

For those eager enough to start on their own - here's a small how-to on making new translations:

make shure you have eric3 installed on your system

download the luma source

start eric3, open project luma and go to the translation tab

then rightclick to add translation

... after this you can pick the file.. you'll find it in ./lib/luma
Translations in Luma can be edited by qt-linguist, so unless you want to edit xml by hand - make shure you have qt-linguist as well.

That's it.. if you make language-translation for a langeuage not supported by Luma today, you're encouraged to mail your file back to the project - and it will most likely show up in the next minor-release followed by a small thank-you in the release-notes.
