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

XCOMM Site administrators are STRONGLY urged to write nicer versions.

XCOMM Check for /usr/bin/X11 and BINDIR in the path, if not add them.
XCOMM This allows startx to be placed in a place like /usr/bin or /usr/local/bin
XCOMM and people may use X without changing their PATH.
XCOMM Note that we put our own bin directory at the front of the path, and
XCOMM the standard SCO path at the back, since if you are using the Xorg
XCOMM server theres a pretty good chance you want to bias the Xorg clients
XCOMM over the old SCO X11R5 clients.

XCOMM First our compiled path

bindir=BINDIR
scobindir=/usr/bin/X11

case $PATH in
  *:$bindir | *:$bindir:* | $bindir:*) ;;
  *) PATH=$bindir:$PATH ;;
esac

XCOMM Now the "SCO" compiled path

case $PATH in
  *:$scobindir | *:$scobindir:* | $scobindir:*) ;;
  *) PATH=$PATH:$scobindir ;;
esac

XCOMM Bourne shell doesn't automatically export modified environment variables
XCOMM so export the new PATH just in case the user changes the shell
export PATH

XCOMM Set up the XMERGE env var so that dos merge is happy under X
