Update of /cvs-repository/Zope3/src/zope/fssync/tests
In directory cvs.zope.org:/tmp/cvs-serv14786/tests

Added Files:
	test_passwd.py 
Log Message:
New password manager for zsync to allow checkouts to not contain everything
required to authenticate to the server.  This implements a persistent cache
for these tokens stored in ~/.zsyncpass (similar to ~/.cvspass).
