If what you need is some tool "to do topological overlay", perhaps the best
way is to use either GRASS (v.overlay & family) or QGis fTools plugin (very
very similar to the good old "swiss army knife" XTools for ArcView GIS[1]).
If you need to work interactively, IMHO QGis (and its GRASS plugin) is the
best tool. Should you prefer an easily programmable tools, maybe GRASS along
with some bash scripting will do.
Of course, these are my 2 Eurocents...
[1] Rats! I mentioned ESRI software... My apologies ot the list, but who needs
ESRI anymore? :)
