+# * Copies default moo2rc from /opt/moo2/
+# * Generates dosboxrc, tweaks sound values and enables full
+# screen
+# * Creates symlink to /opt/moo2/cd, which will contain a copy
+# of the CD if you installed with USE=nocd, or will yet
+# another symlink to your CD-ROM drive where you had the
+# Orion2 CD when you ran the ebuild).
+# * Performs psudo-install into ${HOME}/.moo2/MPS/ORION2
+# * If you specified USE=lordbrazen, it will also run the
+# unofficial patch which is pretty slow.
