I don't know about the "trivial" adjective, but I assert that's the goal, and would give me (and I suspect many others) a dramatic improvement in productivity and usability. The old "get an electic circular saw after years of only using a hand saw" analogy. > My eagle-using colleagues envy me for the hierarchical schematics that I > can draw in gschem. I do this in xcircuit, but at some point I may move to gschem. My biggest motivation, believe it or not, will be the better BOM support. - Larry _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
