/*
|
|
All of Quake's data access is through a hierarchical file system, but the contents of
|
|
the file system can be transparently merged from several sources.
|
|
|
|
The "base directory" is the path to the directory holding the quake.exe and all
|
|
game directories. The sys_* files pass this to host_init in engineparms->basedir.
|
|
This can be overridden with the "-basedir" command line parm to allow code
|
|
debugging in a different directory. The base directory is
|
|
only used during filesystem initialization.
|
|
|
|
The "game directory" is the first tree on the search path and directory
|
|
that all generated files (savegames, screenshots, demos, config files) will
|
|
be saved to. This can be overridden with the "-game" command line parameter.
|
|
The game directory can never be changed while quake is executing.
|
|
This is a precacution against having a malicious server instruct clients
|
|
to write files over areas they shouldn't.
|
|
|
|
The "cache directory" is only used during development to save network bandwidth,
|
|
especially over ISDN / T1 lines. If there is a cache directory
|
|
specified, when a file is found by the normal search path, it will be mirrored
|
|
into the cache directory, then opened there.
|
|
|
|
FIXME:
|
|
The file "parms.txt" will be read out of the game directory and appended to the
|
|
current command line arguments to allow different games to initialize startup
|
|
parms differently. This could be used to add a "-sspeed 22050" for the high
|
|
quality sound edition. Because they are added at the end, they will not override
|
|
an explicit setting on the original command line.
