[Zope] How do I get a list of all methods in a ZClass from DTML ?

Hi ! Is there a way to get a list of all methods in a ZClass from DTML ? By this I don't mean the constructor methods, but the methods in Products/MyProduct/MyZClass/propertysheets/methods I have tried to walk to the methods with dtml-with calls, but it does not work. Unfortunately, ZCatalog also does not find the methods of ZClasses, so I wonder if the methods are actually hidden on purpose ? BTW: I want to document a Product, and for this I need the list of methods, and once I have that, also the content of the methods. TIA, Maik Röder
