During the last documentation sprint, Ross Patterson started a
tutorial/manual explaining what's the portal_catalog tool and how can you
use it into Plone, i.e. ZCatalog Plone-specific bits.
Is anybody interested in taking ownership of this article, reviewing and
polishing it a bit before publishing? Thanks in advance.
