I have just started putting together a How-To related to this.  If
anyone has insight into product debugging or has something to contribute
please set it my way.  The existing Debugging how-to describes some
things but it took a little imagination to jump from Monkey-See to
Monkey-Debug.

Please... correct me if I am wrong!

Test.py that comes with the ZPublisher package was a generic bobo test
script in that publishes resources within modules.  We may wish to
publish the a resource /spam/eggs within Zope, so you pass "Zope" as the
module and /spam/eggs as PATH_INFO:

python Test.py Zope "/spam/eggs" -u "superuser:123"

or from the interpreter:
>>> import ZPublisher
>>> ZPublisher.Zope("/spam/eggs", u="superuser:123")

If you have an empty ZODB then you can add items from the interpreter
(untested and probably unfounded ;)

>>> import Zope
>>> root = Zope.app()
>>> root._setOb('PollSample', Poll("Question", ["Answer1", "Answer2"]))
>>> print root.PollSample
>>> root.getTransaction().commit()

There is one gotcha described in
http://www.zope.org:8080/Documentation/Reference/Debugger where the
environment variable INSTANCE_HOME may need to be set to the zope
directory (/usr/local/zope in my case), I don't know if this has been
fixed.

Newbie warning.... Could someone please describe why Zope is the module
name and not the product one is developing?
