Unfortunately my tx.technion.ac.il/~cben/python site has been down for a couple of weeks. Meanwhile I've moved my python hacks (most notably series.py and dsets.py) to: http://cben-hacks.sourceforge.net/python/ (An http redirect is also in place.) -- Beni Cherniavsky <cben@users.sf.net> Note: I can only read email on week-ends...
