[Zope3-checkins] CVS: Packages/ZConfig - loader.py:1.1.2.25 schema.py:1.1.2.33 url.py:1.1.2.4

[Fred L. Drake, Jr.]

Update of /cvs-repository/Packages/ZConfig
In directory cvs.zope.org:/tmp/cvs-serv20916

Modified Files:
      Tag: zconfig-schema-devel-branch
	loader.py schema.py url.py 
Log Message:
More consistency in URL handling.  Make sure file: URLs *always* get the
"//" hostpart separator, even with Python 2.1, since urllib2.urlopen()
chokes if that is missing.
