Nicely offered, but the guys developing Sourcemod are using the SDK
rather then the files hidden away in the GFC's...
The files in the GFC's are the actual end-product of (some) of what's revieled through the Software Development Kit.
Now I don't now much about this either (yet), but this is as much as I already understood from browsing forums & files.
Those that need acces to the files stuffed away in the GFC's most probably already knew how to get those...
