The master template in the macros tutorial Daniel pointed to, is a
template for instances of ``Master`` view, which is not your 'current'
view. Please review the 'all-purpose-macros' section.

There is no limit in setting up 'masters' of 'masters'. Given you have a
main template 'master.pt', which is bound to a view 'Master' (as done in
the tutorial)::

  class Master(grok.View):

then you can define::

  class Monkeybutter(grok.View):
      grok.context(Interface) # Same as in the `Master` class

or, for short::

  class Monkeybutter(Master):

Add a template ``monkeybutter.pt`` in `app_templates/` which references
the old master template as `context/@@master/macros/master` and
reference the new fascade macros from, for example, indext.pt like


simply replacing '@@master' by '@@monkeybutter'.

I assumed, this would be made clear in the tutorial. Maybe I should
explain it more in-depth.

BTW: In the macros-tutorial all macro references are shown as::

     This is now deprecated and you should use instead::


     (with explicit 'macros/'). I will update this shortly.

Hope that helps,
