Right.  Suppose you create a CMFSite object, 'JustNews', in the
root of your Zope.  You would then create the PythonScript,
perhaps called 'make_just_news', also in the Zope root.  Make
its body::

  types =3D context.portal_types.listContentTypes()
  types.remove( 'News Item' )
  context.portal_types.manage_delObjects( types )

You would then invoke it on your site via URL::

  http://your.site.tld/JustNews/make_just_news

Presto! Change-o!  your site can only add News Items.
