Have you ever wanted to graph data points generated by a running program,
in real time?  The standard Unix graph(1) won't do this, and neither will
GNU graph, as of release 0.17 of the graphics package.  Instead of acting
as a filter, both wait until the input stream has been closed before
plotting the data.

I have now fixed this problem.  The file

    coral.math.arizona.edu:/pub/graph/graph-0.17-RSM.tar

contains dropin replacements for three of the files in the `graph'
subdirectory of the GNU graphics package.  If these modified versions are
used, graph will act as a filter.  Provided, that is, the user specifies
the minimum and maximum values of x and y on the command line.  That's the
most one could ask for.

This is not an official GNU release (though the code is offered to GNU).
My code seems pretty reliable (it's a straightforward rewrite of Rich
Murphey's original code, which is _very_ reliable).  But like Rich's code,
it must be considered an alpha release.

Any comments on my implementation of this new feature should be sent to _me_,
not the GNU folks!  I hope it proves useful.
