Do not point directly to the download able sources, because the change
the version quickly and do not hold old versions online.


Hi,

I have looked at this graph visualization package (noes and edges)
and it can produce PIC output, which is quite use able with groff.

Sorry it is not a preprocessor, but a very nice tool for drawing ER-,
UML- ... -Diagrams.
