This is the sample directory for the network widget.  It contains the
following files:

    xnet1.c	- a chess board for an N queens demo
    xnet2.c	- a good start for simple node and link displays
    xnet3.c	- xnet2 + a line drawing routine + zooming
    xnet3a.c	- contains code for using an image background (needs tif)
    xnet4.c	- xnet2 and simple splines - the builtin ones are better
    xnet5.c	- xnet4 + elliptical symbols - the builtin ones are better
    xnet6.c	- sentence parse tree with a point Callback routine
    xnet7.c	- an incremental branching tree example
    xnet7a.c	- an incremental semi-latice example
    xnet8.c	- a birds eye filter
    xnet9.c	- X resource example - run "xrdb -merge xnet9.xrdb.merge" 1st
    xnet10.c	- arbitrarily shaped pixmaps
    xnet11.c	- builtin shapes, splines, and arrows
    xnet12.c	- dynamic sizing example for John Heck
    xnet13.c	- xnet8 with printing of the network in compressed PostScript

The later examples are better.
