PyUGraph

I am continuing to migrate my old project repositories from CVS to
svn. In the process, today, I found some old code I wrote in 2001 (or
earlier) to generate input files for daVinci, an old di-graph
visualization package. It turns out that daVinci has been renamed to
uGraph, so when I released the code I updated the module name.

There are now other, possibly better, graph visualization tools
available. NetworkX looks very promising. It uses Graphviz, which
produces some really nice output. But, daVinci was the first tool I used
for doing relationship analysis. I used it to analyze calls between
functions in some nasty Perl code I was maintaining. I also used it to
analyze the module linkage dependencies in a large C toolkit library,
with the idea that we would split the big library up into several
smaller .so files for release. And there have been several one-off
projects along the way, too. Unfortunately, I seem to have lost most of
that code.
