Elegant compiler generator available for download

A couple of weeks ago I was looking for a tool to draw a railroad
syntax diagram and I stumbled on the Diagrams program in the Elegant
tool suite. It converts BNF to railroad diagrams.

I googled around for other Elegant information and it seems that after
the initial public release, not much has been going on. There is a
sourceforge site for the Front component, but I couldn't find anything
else.

Diagrams worked well for me but I was intrigued by Elegant. I had a
few hiccups in building Elegant so I decided to archive the changes
and put them up for download.


I'm calling this version 7.2.1 because it has only very minor changes
from the last public release by Philips, 7.2.


For now, the suite is available only as a source download using
subversive, here's the README file:


RELEASE INSTALLATION

The "elegant" at the end of the line above is the directory name that will
