In looking through the environment file loading code, I keep seeing a 
check for base_url in the resource registry. It looks like a way to have 
the registry entries only be the filenames (I suppose relative filenames 
work as well) instead of having to enter the full path every time. The 
base_url would be used as the root URL for those filenames when loading 
them.

Thing is, I can't find any reference to that in the docs. I did a search 
for resource_registry, but the only thing I can find is [1] which 
doesn't talk about base_url.

Is this something that's still supported or was it "turned off" (so to 
speak) by removing the docs about it so users didn't know to use it? Is 
the syntax to just sit it side by side with the resource definitions, 
similar to:

resource_registry:
   "base_url": /home/jdob/my_templates
   "OS::Nova::Server": my_nova.yaml

Or am I just totally missing where in the docs it's talked about (which 
is also terribly possible)?

Thanks :)
