[z3-five] Question about skins usage

It took me some time to find out how to define skins as interfaces etc. but
finally I did this and it works :)

My hook is defined as:

def __before_publishing_traverse__(self, object, REQUEST):
        """ Pre-traversal hook.       
        """
        if not XYZSkin.providedBy(REQUEST):
            applySkin(REQUEST, XYZSkin)

One more question is whether I can/should use LocalSites here?


For the others who want to do something like me or simply
write a skin with Five I'll write few things that should
save you some time, I hope...

Look at:

/lib/python/zope/app/rotterdam   # skin which (at last in Zope 2.9.4)
                                                  # is defined in new 
way (with interfaces)
                                                  # and can be used as 
template

/lib/python/zope/app/publisher/browser/metadirectives.py
                                                  # interfaces with good 
docs
                                                  # about their use

and

http://www.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/SimplifySkinning

which is a proposal so it differs a bit in some places than eg. 
rotterdam implementation.
