How about accepting a list of values from stdin as breakpoints? Something like:

$ echo 0 20 40 50 100 | d.vect.thematic -themecalc=breaks ...

That would, with some extra work, allow things like

$ db.select sql='select mycolumn from thetable' | my_classifier |
d.vect.thematic -themecalc=breaks ...

Would that be useful?

Daniel.
