Henry - what did you try for your parameters to plot?  and did you try:  plot -T png  which should create a more modern png file.

Does anyone have anything put together that can easily do the "leroy"

and produce the graphical map it contains?

I got as far as compiling leroy on 4.1C BSD and feeding the attached files through it.  It ran without errors and produced a file to be fed to plot(1G).  That file is attached; I can't figure out how to do anything useful with it.  I ran it through the xterm Tek 4014 mode and just got garbage.  I'm not really familiar with plot at all, so maybe someone else can easily produce readable output from this file.
