Simple C++ gettext-like toolkit
By admin | December 20, 2009
Here is a small gettext-compatible interface for reading simple translation catalogs (not to be confused with gettext’s *.mo style catalogs, which are binary) in form of “original/english string<tab>translated string”. It is not fool-proof, but you can play around with it and it works.
