+OpenJK is an effort by the JACoders group to maintain and improve
+the game engines on which the Jedi Academy (JA) and Jedi Outcast (JO)
+games run, while maintaining full backwards compatibility with the
+existing games.
+
+According to the official website, support for Jedi Outcast is
+rudimentary and not very well tested, so it is not built by default.
+If you want to build it, pass "BUILDJO=yes" on the command line.
+
+You will need the game data from Jedi Academy. If you don't already own
+Jedi Academy, you can buy it from online stores such as Steam, Amazon
+or GOG.  Copy the contents of the GameData/base directory to
+/opt/JediAcademy/base and/or /opt/JediOutcast/base.
+
+By default, the games only support 4:3 resolutions. For modern monitors
+you have to create /opt/JediAcademy/base/autoexec.cfg and/or
+/opt/JediOutcast/base/autoexec.cfg (change the resolution and FOV to
+your needs):
+
+set r_customWidth "1360"
+set r_customHeight "768"
+set r_mode "-1"
+vid_restart
+cg_fov "97"
+cg_fovaspectadjust 1

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
