[Zope-CMF] error installing CMFCalendar in CMF-1.1beta

[marc lindahl]

Hi Tres,
Thanks for the suggestion...
I think I'm missing something... I put the snippet below into a file called
hoover_metadata.py in Extensions, and then added an External Method in the
root of my portal, and got an error:

Site Error

  An error was encountered while publishing this resource.

  SyntaxError

  Sorry, a site error occurred.
