[Barry Warsaw]

Update of /cvs-repository/Zope3/lib/python/Zope/TAL
In directory cvs.zope.org:/tmp/cvs-serv28155/lib/python/Zope/TAL

Added Files:
	talgettext.py 
Log Message:
Really simple translations extractor for .pt files.  Needs a lot of
work, but at least it gets you going; po-mode doesn't provide a way to
add new entries. :(
