So why not drop that as well ? Note that I'm not saying that these switches are useless - of course they do allow to strip down the Python interpreter. I believe that only very few people are interested in having these options and it's fair enough to put the burden of maintaining these branches on them. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Feb 21 2006) >>> Python/Zope Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ ::: Try mxODBC.Zope.DA for Windows,Linux,Solaris,FreeBSD for free ! :::: _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
