I'm creating a small and privately used .ged-files based reporting program and I am currently at a stage of translating it from Polish to English. I'm having a serious troubles in relation translation. Can I use webtrees translations (which seems just perfect for these two languages) as a base of / to aid to my work?
If yes, then which files in source code I should take into consideration when talking about English<->Polish translation?
webtrees is an open source and is free. Does the same goes for translation files or are they copyrighted by their creators?
