Update of /cvs-repository/Zope3/src/zope/app/browser/skins/debug
In directory cvs.zope.org:/tmp/cvs-serv9444/debug

Added Files:
	__init__.py configure.zcml error_debug.pt exceptions.py 
Log Message:


  - Add a 'debug' skin layer, with a "traceback display" view registered
    against IException.
    
  - Define a 'Debug' skin, which adds this layer to the two layers of
    the 'Rotterdam' skin.
    
  Usage:
  
    If you have a request which blows an exception out beyond the publisher,
    you can repeat the request, prefixing the path with '++Debug++', to see
    the traceback in the output (rather than having to switch context to the
    error logging service).  Particularly useful during application
    development.
