Boring Product is an example Product coded in Python, using a Zope 2 style __init__.py.
This product is deliberately as Boring as "Hello, World" so that budding Zope programmers out there banging their heads against DTML's limitations can get into coding products in Python in a manner quite unlikely to get them into any trouble.
That might seem like an inditement of budding Zope programmers, but if the Zope 1 example and the complete lack of documentation for the Zope 2 method confused me, I presume it'll confuse other people. :)
For documentation, please see How To Create a Boring Product in Python and Zen's copy of Amos' tutoral to the old Product API.
