4XCOMM
5XCOMM This is just a sample implementation of a slightly less primitive
6XCOMM interface than xinit.  It looks for user .xinitrc and .xserverrc
7XCOMM files, then system xinitrc and xserverrc files, else lets xinit choose
8XCOMM its default.  The system xinitrc should probably do things like check
9XCOMM for .Xresources files and merge them in, startup up a window manager,
10XCOMM and pop a clock and serveral xterms.
11XCOMM
12XCOMM Site administrators are STRONGLY urged to write nicer versions.

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

33    *:$bindir | *:$bindir:* | $bindir:*) ;;
34    *) PATH=$bindir:$PATH ;;

52XCOMM so export the new PATH just in case the user changes the shell
