+# @BLURB: Standardizing the install of games.
+# @DESCRIPTION:
+# This eclass makes sure that games are consistently handled in gentoo.
+# It installs game files by default in FHS-compatible directories
+# like /usr/share/games and sets more restrictive permissions in order
+# to avoid some security bugs.
 #
-# This is the games eclass for standardizing the install of games ...
-# you better have a *good* reason why you're *not* using games.eclass
-# in a games-* ebuild
+# The installation directories as well as the user and group files are
+# installed as can be controlled by the user. See the variables like
+# GAMES_BINDIR, GAMES_USER etc. below. These are NOT supposed to be set
+# by ebuilds!
+#
+# For a general guide on writing games ebuilds, see:
+# https://wiki.gentoo.org/wiki/Project:Games/Ebuild_howto
