Comment 15 for bug 820471

If you want to add support for MPQ archives, it should be in wartool binary. I already moved/rewritten all other programs/scripts into wartool, because I wanted to have one binary which extract data (without needs to run other binary or script which do something...). Of course you do not need to put functions into wartool.cpp file. You can add new functions into new cpp files and just call then from wartoot.cpp. Or you can also call external programs from wartool (if it is not possible to include code just to wartool binary). But make sure that wartool will extract & covert all data without need to run other script/program manually.

Other solution is to add MPQ and needed data support to Universal Extractor, but I do not know state of this project...
