[Zope] Formatting numbers with commas in Python Script or ZPT

[Dennis Allison]

You can't use re in normal Zope.  You can modify Zope to allow it--follow
the instructions in the PythonScript product.

As for the formatting, I think you have to do it by hand, convert to an
integer, convert the integer to a string, then insert commas and decimals
as needed.
