Cheetah_ is a very good templating language, especially because it's
the one (correct me if i'm wrong) to apply the Object-Oriented model
to Documents. It can seem a bit weird at the beginning but when you get
used to it, you can't live without it :-)

So, i was looking for a good way to overload template parts without
pain, here is how (couldn't find the trick on Cheetah doc):

1. Assume you have a template ``Package/Page.tmpl`` like that:

   ::

      #def footer
        This is my foot !
      #end def

2. Create a ``Page_custom.tmpl`` template:

   ::

      #extends Package.Page

      #def footer
        $Page.footer($self) Where's my mind ? (dixit the Pixies)
      #end def

3. You need to put a ``self`` variable in the template's searchList
   which is the Cheetah template instance itself :-)

I don't think that trick will work if you don't compile your templates
to Python code.
