[Zope-Checkins] CVS: Zope3/lib/python/Zope/App/ZopePublication/Browser - BrowserPublication.py:1.1.2.1 BrowserPublicationTraverse.py:1.1.2.1 BrowserTraversers.py:1.1.2.1 __init__.py:1.1.2.1 browser.zcml:1.1.2.1

[Stephan Richter]

Update of /cvs-repository/Zope3/lib/python/Zope/App/ZopePublication/Browser
In directory cvs.zope.org:/tmp/cvs-serv12070/Browser

Added Files:
      Tag: srichter-OFS_Formulator-branch
	BrowserPublication.py BrowserPublicationTraverse.py 
	BrowserTraversers.py __init__.py browser.zcml 
Log Message:
This package got a major revamp, so here is what I have done:

- reorganized the package in a way that it becomes multiple-protocol 
  firendly, like the Publisher.

- Separated generic code from Browser code

- Removed Traversers.py and PublicationTraverse.py for the above reason

- Refactor Browser{Publication|PublicationTraverse|Traversers}

- Same as above with XML-RPC


ToDo:

- Write tests.

- Update interfaces
