[Uml-devel] auto-layout and graphviz

[Dimitri Ognibene]

a little hint, I hope can be useful but I suppose you have more knowledge of
the field then me, did you look at Dia? there are some tools that look nice,
but i'vent still tryed them.
ps I've very little time for this task that is completely collateral but i
think it can be useful to umbrello community. So if anyone is interested in
developing a system to obtain autolayout I'll glad to get help
