QCC is the original QuakeC compiler created by John Carmack of id Software, used to generate `progs.dat' file that essentially holds game logic behind the graphic engine. It is used primarily to create modifications for Quake and QuakeWorld. Note that more feature-rich, optimizing QuakeC compilers are available in the Ports Collection.
