42 // Win32 requires us to add O_BINARY, but the other OSes don't have it
50 All of Quake's data access is through a hierchal file system, but the contents
51 of the file system can be transparently merged from several sources.
53 The "base directory" is the path to the directory holding the quake.exe and
54 all game directories. The sys_* files pass this to host_init in
55 quakeparms_t->basedir. This can be overridden with the "-basedir" command
56 line parm to allow code debugging in a different directory. The base
57 directory is only used during filesystem initialization.
59 The "game directory" is the first tree on the search path and directory that
60 all generated files (savegames, screenshots, demos, config files) will be
61 saved to. This can be overridden with the "-game" command line parameter.
62 The game directory can never be changed while quake is executing. This is a
63 precaution against having a malicious server instruct clients to write files
64 over areas they shouldn't.
