French translation

Hello

I've read somewhere that no french translation was planned.

I feel ready to perform the translation if you can confirm some few things.

a.) Is it possible to do a translation only by editing xml files ?

b.) Is it possible then to share the modified files with other users ?

c.) Is it allowed to do such work or is it copyrighted ?

d.) Does it make any sense or is it stupid to start such a work ?

Thanks.
