[Zope] V iewlet in rotterdam?

[Derek Richardson]

Zope 3.3

I want to add a viewlet to the rotterdam skin. I don't want to create my 
own skin. is there an accepted way of doing this? I'm surprised that the 
left sidebar in rotterdam doesn't appear to have  a viewlet manager. I 
have been unable to find any declarations in zcml (grepped for 
viewletManager through the entire zope source, didn't see anything 
relevant).

It looks like rotterdam makes do with macros, instead of using viewlets. 
Is there a reason for this? Seems like the left sidebar is perfect for a 
manager, with a viewlet for navigation and another for the add menu.

I am writing a syndication (web feeds: Atom, RSS, etc) package for zope 
and want to plug my viewlet for accessing feed links directly into 
rotterdam. Perhaps this isn't the way to do it, but it seems to me that 
a package like mine that provides general functionality shouldn't define 
its own skin, but should be usable in other skins. Am I wrong?

Thanks,

Derek
