STGM, stands for Shadow-Team Game Modification which started in the mid of 2008 based on scripts 3.4.4 (I think, can't remember) solely used in Gamerz0ne and Shadow-Team servers (well, memories) with enhanced features for administration and from other servers. (Copy-cat will waste their time on features which are worth to copy )
That's the end of bullshit. Attached the source code and feel free to re-use if you found it useful.
No readme, no documentation and no support as usual.
