[Zope-Checkins] CVS: Zope3/lib/python/Zope/App/OFS/Content/File/Views/VFS - VFSFileView.py:1.1.2.1 __init__.py:1.1.2.1 vfs.zcml:1.1.2.1

[Stephan Richter]

Update of /cvs-repository/Zope3/lib/python/Zope/App/OFS/Content/File/Views/VFS
In directory cvs.zope.org:/tmp/cvs-serv23463/lib/python/Zope/App/OFS/Content/File/Views/VFS

Added Files:
      Tag: Zope3-Server-Branch
	VFSFileView.py __init__.py vfs.zcml 
Log Message:
Okay, it finally works! We have a Publisher FTP server again. All the basic
functionalitry is there, from dir listing, file transfer to security.

I punted for now on recognizing file endings, since Jim wants to write a 
proposal for that next week. Also, I did not solve the statistical file
information problem, since this takes some more research.
