I need to have the different languages stored in the separate *.sil files (English.sil, Dutch.sil etc).
I can implement it by manually creation of these files and then use LoadAllFromFile method to get appropriate language strings. But maybe there is another way to do it a little easier?
You can hold all languages in one file on your side and just before release create each language file by deleting all languages except needed and save file under different name.
