I would know if it's possible to translate the tomato's GUI in french and how to ? As this site, it's possible to have the same page with the possibility to translate in french (documentation and tutorial) ? (or other basic language of course)
Question of languages was already asked: translating the Tomato GUI is a huge work, as many sources must be modified and all the build process adapted. Teddy can't handle this. But he already said that if someone was happy to do it…. as it is open source everything is possible.
I'm not a developper but it would mean probably modifying all the structure to have independant language source file before compiling like you can have in localization Linux/GNU packages.
Same for the site.
