[Zope-CVS] CVS: Products/AdaptableStorage/gateway_fs - FSConnection.py:1.5

[Shane Hathaway]

Update of /cvs-repository/Products/AdaptableStorage/gateway_fs
In directory cvs.zope.org:/tmp/cvs-serv13064/gateway_fs

Modified Files:
	FSConnection.py 
Log Message:
- Added ITPCConnection.  It doesn't really belong in the serial
package, but there's no other good place for it right now.

- FSConnection now allows a hidden filename prefix other than
".", such as "_", taking advantage of the fact that the Zope 2 security
model disallows leading underscores.

- Added some more docs.
