-// LordHavoc:
-// Highly optimized port of SV_ClientThink from engine code to QuakeC.
-// No behavior changes! This code is much shorter and probably faster than
-// the engine code :)
-
-// note that darkplaces engine will call this function if it finds it,
-// so modify for your own mods and enjoy...
-
-// note also, this code uses some builtin functions from dpextensions.qc
-// (included with darkplaces engine releases)
-
-// P.S. if you find something weird in this code, it's just mimicing weird
-// stuff in the original quake engine code (which was so unreadable it was
-// hard to even identify what it was doing)
