.SH DESCRIPTION
|
||
|
|
.PP
|
||
|
|
Chocolate Doom is a modern doom engine designed to behave
|
||
|
|
as similar to the original doom game as is possible.

.SH ENVIRONMENT
|
||
|
|
This section describes environment variables that control Chocolate Doom's
|
||
|
|
behavior.
|
||
|
|
.TP
|
||
|
|
\fBDOOMWADDIR\fR, \fBDOOMWADPATH\fR
|
||
|
|
These environment variables provide paths to search for Doom .WAD files when
|
||
|
|
looking for a game IWAD file or a PWAD file specified with the `-file' option.
|
||
|
|
\fBDOOMWADDIR\fR specifies a single path in which to look for WAD files,
|
||
|
|
while \fBDOOMWWADPATH\fR specifies a colon-separated list of paths to search.
|
||
|
|
.TP
|
||
|
|
\fBPCSOUND_DRIVER\fR
|
||
|
|
When running in PC speaker sound effect mode, this environment variable
|
||
|
|
specifies a PC speaker driver to use for sound effect playback. Valid
|
||
|
|
options are "Linux" for the Linux console mode driver, "BSD" for the
|
||
|
|
NetBSD/OpenBSD PC speaker driver, and "SDL" for SDL-based emulated PC speaker
|
||
|
|
playback (using the digital output).
|
||
|
|
.TP
|
||
|
|
\fBOPL_DRIVER\fR
|
||
|
|
When using OPL MIDI playback, this environment variable specifies an
|
||
|
|
OPL backend driver to use. Valid options are "SDL" for an SDL-based
|
||
|
|
software emulated OPL chip, "Linux" for the Linux hardware OPL driver,
|
||
|
|
and "OpenBSD" for the OpenBSD/NetBSD hardware OPL driver.
|
||
|
|
|
||
|
|
Generally speaking, a real hardware OPL chip sounds better than software
|
||
|
|
emulation; however, modern machines do not often include one. If
|
||
|
|
present, it may still require extra work to set up and elevated
|
||
|
|
security privileges to access.
|
||
|
|
