Instead of trying to parse some version string, distutils should require defining the version as tuple with well-defined entries - much like what we have in sys.version_info for Python. The developer can then still use whatever string format s/he wants. The version compare function would then work on this version tuple and probably be called cmp() (at least in Python 2.x ;-). -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Mar 27 2009) >>> Python/Zope Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ 2009-03-19: Released mxODBC.Connect 1.0.1 http://python.egenix.com/ ::: Try our new mxODBC.Connect Python Database Interface for free ! :::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.
