In directory cvs.zope.org:/tmp/cvs-serv21650/lib/python/Zope/Publisher/VFS

Added Files:
      Tag: Zope3-Server-Branch
	IVFSDirectoryPublisher.py IVFSFilePublisher.py

	VFSRequest.py VFSResponse.py __init__.py metaConfigure.py 
	vfs-meta.py vfs-meta.zcml 
Log Message:
Worked some more on FTP, especially in regards with the Publisher.

- Finally we can get rid of the medusa base. I think I have extracted all
  of the interesting code.

- Started on a PublisherFileSystem. A few methods might work, but most of 
  the FS methods are not hooked up yet.

- Started writing VFS Publisher hooks.

- Added the FTPServer to the startup registry. It comes up, but do not 
  expect it to work, since no views have been written for VFS yet.
