-# The environment should look like this:
-# Note: the base_url, urls and files should be handled earlier
-#       and by the time it gets to the engine they are all just names.

-# Use case 1: I want to use all the resource types from provider X
-#resource_registry:
-#  "OS::*": "Dreamhost::*"
-#  # could also use a url like this (assuming they could all be
-#  # expressed in nested stacks)
-#  "OS::*": http://dreamhost.com/bla/resources-types/*"

-# Use case 2: I want to use mostly the default resources except my
-# custom one for a particular resource in the template.

-#  resources:
-#    my_db_server:
