[Zope3-checkins] CVS: Zope3/lib/python/Zope/App/OFS/Content/Folder/Views/VFS - FolderView.py:1.2

[Stephan Richter]

Update of /cvs-repository/Zope3/lib/python/Zope/App/OFS/Content/Folder/Views/VFS
In directory cvs.zope.org:/tmp/cvs-serv26132/Zope/App/OFS/Content/Folder/Views/VFS

Modified Files:
	FolderView.py 
Log Message:
Implemented VFS views for the Local Service Manager. You can now traverse
into it up to Packages. 

Since Jim did not tell me what he wanted to do in a Package, I did not 
add much there, so that all Services are shown as directories now. The 
only binding I implemented was for the ZPTTemplate, which works fine so
that you can add ZPTs via VFS now. I could imagine doing the same for 
Module, but other than that Package is rather boring from a VFS point of
view.

Of course we could do some "magic" and display a text (file content) 
representation of the various services, but I do not know how useful this 
would be.
