# This exists because I have a text log-in and start my X-Server
# manually.  I have the following alias set:
#   alias s='if [ ! ${DISPLAY} ]; then \
#            (map --sleep 15 &);       \
#            startx 2> ${HOME}/.Xsession-errors; exec true; fi'
# which means this script sits around until X has started before
# running.
