"""\
This file is an installation script for CMFForum (ZPT skins). It's meant
to be used as an External Method. To use, add an external method to the
root of the CMF Site that you want ZPT skins registered in with the
configuration:
id: install_forum
title: Install Forum Product *optional*
module name: CMFForum.Install
function name: install
Then go to the management screen for the newly added external method
and click the 'Test' tab. The install function will execute and give
information about the steps it took to register and install the
ZPT skins into the CMF Site instance.
