[Zope] Xron not compatible with Zope 2.5.1?

[VanL]

Hello,

I installed the Xron product, and I can't seem to use it with Zope 
2.5.1.  Whenever I try to view a Xron DTML method, I get the following:


    Site Error

An error was encountered while publishing this resource.

Debugging Notice

Zope has encountered a problem publishing your object.

The object at http://mig:8080/team/vanl/test has an empty or missing 
docstring. Objects must have a docstring to be published.



Has anyone seen this before?  Is there something that has superceded 
Xron that is currently maintained?

Thanks,

VanL
