Packages that could be generic and eventually might, in changed form,
end up in the Zope 3 core or Zope 3 ECM, but that we (at Infrae) built
in isolation for now, as we're in a hurry to use them.

It includes:

hurry.query - higher level query system built on top of the Zope 3
              catalog. Some inspiration came from Dieter Maurer's
              AdvancedQuery. See src/hurry/query/query.txt for
              documentation.

hurry.workflow - a simple but quite nifty workflow system. See
             src/hurry/workflow/workflow.txt for documentation.

hurry.file - advanced file widget which tries its best to behave like
             other widgets. See the doctest in
             src/hurry/file/browser/file.txt for some documentation.
