You create new objects by:

    someObjectManager.manage_addProduct[ProductName].constructor(args...)

"someObjectManager" is the destination where the new objects should be
created in. Usually, it is a Folder.

"ProductName" is the name of the product that defines the class
that should be instantiated. It is 'OFSP' for many Zope builtin
classes (e.g. "Folder", "DTMLMethod"). PythonScripts and
PageTemplates live in their own product, however.

"constructor" is the constructor to create instances of your class.
It is (e.g.) "manage_addFolder" to create a folder and "manage_addFile"
to create a file. Look for "registerClass" in the products "__init__.py".
