[Zope] problem with External Methods

[Chris McDonough]

You can't use a class object as a function... in this case, you're defining
the function name in the external method as "mp3info", which is a class,
which is why you're getting this error.

I don't see any functions at all in the file you posted.  An external method
wraps a Python function.  Passing instances of classes defined in an
external method is tricky as well, even if you are using a function.

It seems like you really want to be building a Product.  See the Zope
Developer's Guide at http://www.zope.org/Documentation/ZDG for information
on how to do this.
