[Zope3-checkins] CVS: Zope3/src/zope/app/pagetemplate/tests - test_directives.py:1.1

[Matt Hamilton]

Update of /cvs-repository/Zope3/src/zope/app/pagetemplate/tests
In directory cvs.zope.org:/tmp/cvs-serv2345/src/zope/app/pagetemplate/tests

Added Files:
	test_directives.py 
Log Message:
Extended TALES namespace functionality to Zope3.  You can now use 
TALES expressions such as foo/zope:title within ZPT.

Currently only a single function 'title' has been created within
talesapi.py, now we need to work out which functionality we want to 
expose ;-)  Probably look through the ZQR and places like that.
