Decompiling .luac files

Hi there,

So, basically I have one compiled LUA project with file.luac extension. What I want to do is to de-compile it and get the original code. I tried luaDec, unluac and pretty much everything but none of those seems to know "luac" filetype. Anyway, if you have an answer than reply, but please don't write me something like : "You want to steal others' script" because that won't do anything.

Thanks in advance
