+o2em is an emulator for the Magnavox Odyssey II and VideoPac+ systems.
+
+This requires allegro.
+
+The Odyssey2 BIOS ROM image is required for emulation. To include it in
+the package, get either the odyssey2.zip used with MESS, or else the ROM
+image itself, called either o2rom.bin or o2bios.rom, and place it in the
+build directory before running the SlackBuild. The ROM will be installed
+in /usr/share/o2em/bios/o2rom.bin; if you build the package without the
+ROM, just place a copy of the ROM there after installing the package.

+.SH FILES
+.TP
+\fB/usr/bin/o2em\fR
+Shell script wrapper. Sets up ~/.o2em if needed, runs the actual
+binary. This is required because o2em was ported from DOS, and
+expects to be run in its own directory; with the wrapper, it
+behaves like a proper UNIX program (run anywhere, writes only
+to ~/.o2em).
+.TP
+\fB/usr/libexec/o2em.bin\fR
+The actual o2em binary. Normally, you don't want to run this
+directly (let the wrapper run it for you).
+.TP
+\fB/usr/share/o2em/bios\fR
+BIOS ROM images. At minimum, \fBo2rom.bin\fR must exist. To use the
+\fB\-c52\fR,
+\fB\-jopac\fR, or
+\fB\-g7400\fR
+options, the appropriate BIOS image must be located here (see below).
+The emulator checks the CRC of the ROM images,
+and will refuse to start with an image it doesn't recognize. The correct
+files are:
+.PP
+c52.bin (md5sum f1071cdb0b6b10dde94d3bc8a6146387)
+.br
+g7400.bin (md5sum c500ff71236068e0dc0d0603d265ae76)
+.br
+jopac.bin (md5sum 279008e4a0db2dc5f1c048853b033828)
+.br
+o2rom.bin (md5sum 562d5ebf9e030a40d6fabfc2f33139fd)
+.PP
+These are the same files used by MESS, except o2rom.bin is called
+o2bios.rom by MESS.
+.TP
+\fB/usr/share/o2em/voice\fR
+Voice samples, used to emulate the Odyssey2's speech synthesis chip.
+.TP
+\fB~/.o2em/\fR
+Working directory for o2em. Will be created by shell script wrapper
+the first time it's run. All save\-state and screenshot files will be
+written here. The BIOS image, cartridge images, and voice samples will
+be symlinked into this directory by the wrapper script.
+.TP
+\fB~/.o2em/o2em_def.cfg\fR
+Config file (optional). See o2em.txt for details.
+.TP
+\fB/usr/doc/o2em\-\fR\fI$VERSION\fR\fB/o2em.txt\fR
+Full documentation for o2em.
+.SH AUTHORS
+o2em was originally created by Daniel Boris, and has been developed by
+Andre de la Rocha since version 0.80 and Arlindo M. de Oliveira since version 1.16.
+.PP
+This manual page was written by B. Watson for the SlackBuilds.org project (but
+may be used by anyone for any reason).
+.PP
+Wrapper script also by B. Watson.
