This is a modified version of VMEX 0.98g (Valve Map Extractor) by Rof, a .bsp to .vmf map decompiler for Source Engine maps.
The development of this tool seems to be dead now, so I want to reanimate it with this mod.
Original version available on http://www.bagthorpe.org/bob/cofrdrbob/

Feel free to contact me at barracuda415@yahoo.de for questions, suggestions and bug reports.
