[Zope-Checkins] CVS: Zope3 - stupid_build.py:1.1.2.6

[Guido van Rossum]

Update of /cvs-repository/Zope3
In directory cvs.zope.org:/tmp/cvs-serv21763

Modified Files:
      Tag: Zope-3x-branch
	stupid_build.py 
Log Message:
Before running setup.py, remove all stale .pyc and .pyo files.

Hopefully this will prevent future generations the kind of
embarrasment that befell Casey Duncan tonight: he removed various
files that were still in use, but didn't notice (probably) because the
.pyc files were still there.
