[Zope] - How do I publish this object?

[skip@calendar.com (Skip Montanaro)]

I believe this was asked yesterday, but I don't recall seeing an answer
posted yet, so I'll ask again, in case it wasn't noticed by those with
enough Zope Zen.

While I was in the shower last night (what is it about the shower with this
group?) it dawned on me that what I don't get about Zope is how to publish
an object in much the same way I would have done using Bobo.

As an example, appended is a small module, cal.py, which uses the Unix cal
command to generate an ASCII calendar.  How would I make that available
through Zope?  Seeing how that is done would be a big step forward for me.

Thx,
