[Zope] Edit ZClass Properties

[Borislav]

Hi,

The problem I'm trying to solve is how to change the values of 
properties of a ZClass from a python script. Simple assignment does not 
work, e.g. myZClass['aProperty'] = value

I did a web search and found some HOWTOs mentioning a method 
'manage_editProperties'. I could not find any documentation about this 
method in 'The Zope Book' or the Zope help. Is there another place to 
look for API documentation that I am not aware of?

My main question is: what is the procedure to change properties of a 
ZClass programatically?

Thanks.
