#
# This is just a sample implementation of a slightly less primitive
# interface than xinit.  It looks for user .xinitrc and .xserverrc
# files, then system xinitrc and xserverrc files, else lets xinit choose
# its default.  The system xinitrc should probably do things like check
# for .Xresources files and merge them in, startup up a window manager,
# and pop a clock and serveral xterms.
#
# Site administrators are STRONGLY urged to write nicer versions.
