# 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, start up a window manager,
# and pop a clock and several xterms.
