Yes indeed... fwiw, this is mentioned in the 2.6 edition of the
Zope Book.  Maybe not easy to find, but it's there, in the
"advanced scripting" chapter:

"""
Add a new object to the context

  Scripts can add objects to folders, just like you do in the Zope 
  management interface. The context has to be a folderish object 
  (i.e. a folder or another object derived from ObjectManager). 
  The general pattern is:

    context.manage_addProduct['PackageName'].manage_addProductName(id)

  manage_addProduct is a mapping in which we can look up a dispatcher - 
  an object which gives us the necessary factory for creating a new 
  object in the context. For most of the built-in Zope classes, the 
  PackageName is OFSP, and the factory method is named after the product 
  class itself. Once you have the factory method, you must pass it 
  whatever arguments are needed for adding an object of this type. 
  Some examples will make this clear.
  ...
"""

I highly recommend re-reading that chapter (and the rest of the book)
every now and then - even though I co-edited the chapter I still forget 
things and have to look them up again :-)
