For some pointers look at this thread where I posted a similar question: http://groups.google.com/group/comp.lang.python/browse_frm/thread/1a1d2ed9d05d11d0/56684b795fc527cc#56684b795fc527cc I am surprised that libraries to do that are not more common. I guess everybody rolls his own. -- http://mail.python.org/mailman/listinfo/python-list
