+\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.
