gwm reminds me:
As I may have pointed out, I work mainly on Windows (NT), at a company which also sells software. One of the applications we developed (I only really did translations) is a product called "Language Manager" which translated Windows 3.1 menus and buttons into another language on the fly. The applications being translated didn't need to know they were getting translated. It was highly successful, we finished it in 1994 just 1 year before Win 95 made Win 3.1 obsolete. Progress has stalled on the port to Win 95/NT but as we have now too much other work. I've been pushing to release it under the GNU licence in the hope of getting it finished.
Language Manager is of course very Windows specific and it was never written with portability in mind. But it does seem to me that the concept of giving user control over user interface language is a good idea. Is there anything similar out there in the X free world?
Is anyone out there keen on working on a project like this?
