[Grok-dev] Re: Recipe for "egg-like" reuse?

I did <include package="AddApp" /> (when it should have been "addapp")  
and when it didn't work I was trying other ways, eventually ending up  
with an entry

   <grok:grok package="protoncms" />

in configure.zcml. I have reverted to your suggestion and it works  
equally well. Now I am only struggling to get the grok.Permissions to  
work again. I have defined:

   class ViewContacts(grok.Permission):

But I still get the error "Undefined permission 'protoncms.EditUser'".
