# This script is run in two instances:
#   1.  It was hooked into XDM via twiddling xdm-config.
#   2.  It was hooked into legacy GDM via inserting a script in
#       /etc/X11/xinitrc.d.
#
# This script's responsibility is primarily to launch vmware-user during
# X session startup.  In the XDM case, after launching vmware-user, we
# resume executing the original, system Xsession script.  In the GDM
# case, we do nothing else.
#
# usage: xsession-xdm.sh [-gdm]
#    -gdm: Indicates caller is the GDM helper (xsession-gdm); run
#          vmware-user -only-, then exit.
