[Zope] the "manage_" methods

Hello I am trying to realize how the manage_ DTML methods works. The only documentation that I found was a quick reference that just say that the methods exist with simple descriptions as: manage_addDTMLMethod(id, [title, file, REQUEST, submit]) But there is no details about how this works, what´s required. Is there any documentation about them? I am trying to do a webpage that can change the content of properties of a folder. Regards.
