copy against a remote non-file non-checkout out copy - it'll basically 
never work.

aside from the review script, nothing wrong with pushing from your home 
checkout straight to the main git repo on doppio.

those working with the review script should just do a checkout of 
moonbase in their home folder on doppio.
