+#
+# This is SORT OF LIKE an X session, but not quite.  You get a command as the
+# first argument (it could be multiple words, so run it with "eval").  As a
+# special case, the command can be:
+#  default - Run the appropriate Xclients startup (see the code below)
+#  custom - Run ~/.xsession and if that's not available run 'default'
+#
+# (Note that other arguments could also follow, but only the command one is
+# right now relevant and supported)
+#
+# The output is ALREADY redirected to .xsession-errors in GDM.  This way
+# .xsession-errors actually gets more output such as if the PreSession script
+# is failing.  This also prevents DoS attacks if some app in the users session
+# can be prodded to dump lots of stuff on the stdout/stderr.  We wish to be
+# robust don't we?  In case you wish to use an existing script for other DM's,
+# you can just not redirect when GDMSESSION is set.  GDMSESSION will always
+# be set from gdm.
+#
+# Also note that this is not run as a login shell, this is just executed.
+# This is why we source the profile files below.
+#
+# based on:
