To compile just type make from openwindows and an executable called 
display should be created.  Move it to a place where it will be found,
such as /usr/local/bin. 

To use the program just type 

	xyplot file.xy | display

and a window should pop up with the plot.  If you click the left button
inside the window it gets killed.  The window can be resized and
closed.  If you downsize, then it has to be refreshed (from the menu)
to get the smaller plot.

This is still beta software.
