[Product-Developers] Grabbing app root in Product initialization ...

[Gilles Lenfant]

Thanks for this,

I'll try this for the next releases of my control panels (aws.zope2zcmldoc and aws.monkeypatcherpanel). They actually need a manual installation since I didn't find the way to add automatically a control panel at zope startup.

Cheers
