[Grok-dev] Grok emerging from the dependencies

[Souheil CHELFOUH]

Thank you Martijn for this work and I'm glad we are finally seeing the
bottom of the zope.app pit.
As for the megrok dependencies, you once talked about integrating the
megrok.layout to the grok core.
I think that would be a good think. It's, at least, as useful as
grok.View for many usages.
megrok.menu can be, in the long run, removed to use something more
powerful and more widespread.
It would be good if Grok community could try and work hand in hand in
producing higher level packages too, that are commonly used in many
website cases.
