44 this file was copied out of the common directory in order to not break
45 compatibility with the q3map 1.x tree. it was moved out in order to support
46 the raven bsp format (RBSP) used in soldier of fortune 2 and jedi knight 2.
48 since each game has its own set of particular features, the data structures
49 below no longer directly correspond to the binary format of a particular game.
51 the translation will be done at bsp load/save time to keep any sort of
52 special-case code messiness out of the rest of the program.
