[Zope-Checkins] CVS: Zope3/lib/python/Zope/ContextWrapper - IWrapper.py:1.3

[Steve Alexander]

Update of /cvs-repository/Zope3/lib/python/Zope/ContextWrapper
In directory cvs.zope.org:/tmp/cvs-serv22871/lib/python/Zope/ContextWrapper

Modified Files:
	IWrapper.py 
Log Message:
Added a set of convenience functions that you can import from
Zope.App.Traversing.

Fixed a few typos in the ContextWrapper docstrings, and also added
an isWrapper method to Zope/Proxy/IContextWrapper, mainly so that
I can raise nice errors if the convenience functions are passed
an unwrapped object, rather than returning objs or Nones or []s and 
having programs fail at tenuously related other places.
