# Note that this is SORT OF LIKE an X session, but not quite.  You get a
# .desktop file as the first argument.  You must here then parse the
# Exec= line out of this file and use that.
# As a special case, the Exec line can be:
#  failsafe - Run an xterm only
#  Xclients - Run the appropriate Xclients startup (see the code below)
#
# You should also handle an argument of 'failsafe'
#
# Note that 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.  We wish to be robust don't we?
#
# 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:
