[Zope] "No module named rotor"

[Dennis Allison]

Rotor was removed form python for a variety of reasons (see the mailing 
list archives) but one of them was that it's a terrible way to do any sort 
of encryption.  There are numberous python extensions that do encryption
and decryption which could be incorporated into your product.  
Alternatively, you can add rotor as a python script into your product--
and interesting programming project <smile.

Or you can add back in the rotormodule as a Python Extension.

The rotormodule can be picked up for the Module directory of the 
Python 1.5 directory.
