#!@XSESSION_SHELL@
#
# 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:
# $XConsortium: Xsession /main/10 1995/12/18 18:21:28 gildea $
command="$@"
# this will go into the .xsession-errors along with all other echo's
