[Fred L. D. <fd...@us...>]

Update of /cvsroot/cvs-syncmail/syncmail/tests
In directory sc8-pr-cvs1:/tmp/cvs-serv12297/tests

Added Files:
      Tag: new-config-branch
	syncmail.py test_options.py 
Log Message:
Move the tests to a subdir, and make them use a proxy module that deals
with loading code from the syncmail script.
This provides better namespace isolation between syncmail and the tests.
