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