3XCOMM
4XCOMM This is just a sample implementation of a slightly less primitive
5XCOMM interface than xinit.  It looks for user .xinitrc and .xserverrc
6XCOMM files, then system xinitrc and xserverrc files, else lets xinit choose
7XCOMM its default.  The system xinitrc should probably do things like check
8XCOMM for .Xresources files and merge them in, start up a window manager,
9XCOMM and pop a clock and several xterms.
10XCOMM
11XCOMM Site administrators are STRONGLY urged to write nicer versions.

19XCOMM Check for /usr/bin/X11 and BINDIR in the path, if not add them.
20XCOMM This allows startx to be placed in a place like /usr/bin or /usr/local/bin
21XCOMM and people may use X without changing their PATH.
22XCOMM Note that we put our own bin directory at the front of the path, and
23XCOMM the standard system path at the back, since if you are using the Xorg
24XCOMM server there's a pretty good chance you want to bias the Xorg clients
25XCOMM over the old system's clients.
26
27XCOMM First our compiled path

30case $PATH in
31    *:$bindir | *:$bindir:* | $bindir:*) ;;
32    *) PATH=$bindir:$PATH ;;
33esac
34
35XCOMM Now the "old" compiled path
36oldbindir=/usr/X11R6/bin

38if [ -d "$oldbindir" ] ; then
39    case $PATH in

41        *) PATH=$PATH:$oldbindir ;;
42    esac
43fi
44
45XCOMM Bourne shell does not automatically export modified environment variables
46XCOMM so export the new PATH just in case the user changes the shell
