+# 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

+#  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
