	# We want to use YAML without VCR loaded, to isolate our testing to just YAML.
	# However, the yaml files reference some VCR types, so we have to load them.
	# Alternately, you can just copy the VCR struct definitions from:
	# http://github.com/myronmarston/vcr/blob/v1.0.0/lib/vcr/structs.rb
	$LOAD_PATH.unshift('path/to/vcr/lib/dir')
