[Zope] Creating permissions..

[Joonas Rapila]

Hi everyone

I have a question about creating new "Permissions" in the security 
section of an object, is it possible and if it is, then how? i.ex:

---------------------------------------------------------------------- 
------------
| Acquire         Permissions                         Roles 
|
| permission                                          Anonymous 
Manager  Owner  |
| settings 
|
| 
|
| X               Access contents information          X            X 
X    |
| X               Change DTML Methods                  _            X 
X    |
| X               Edit Document (this is the 
|
|                new one I'd like to create)           _            X 
X    |
---------------------------------------------------------------------- 
------------

Is this possible?
