[Plone-UI] Skinning Navigation Portlet in Plone 3 - how do you override sub macros?

[A Bowtell]

I'm not sure that this is actually the template you need. Most of the new
portlet files are now in an egg:

plone/app/portlets/portlets

The file you need there is called navigation_recurse.

I asked a similar question a few months ago
