[Zope3-checkins] CVS: Zope3/src/zope/app/pagetemplate - engine.py:1.18.14.1

[Stephan Richter]

Update of /cvs-repository/Zope3/src/zope/app/pagetemplate
In directory cvs.zope.org:/tmp/cvs-serv26608/pagetemplate

Modified Files:
      Tag: srichter-inlinepython-branch
	engine.py 
Log Message:
Hooked up the new TAL script support to Templated Pages. The support has to
be manually activated on a separate page (as requested by __gotcha).

Also, currently we only have support for the "text/server-python" type. 
Later we might want to add other languages too.

TO DO:

  - tests

  - documentation
