# This middleware sets various version related rack environment variables
# based on the uri path and removes the version substring from the uri
# path. If the version substring does not match any potential initialized
# versions, a 404 error is thrown.
#
# Example: For a uri path
# /v1/resource
#
# The following rack env variables are set and path is rewritten to
# '/resource':
#
# env['api.version'] => 'v1'
#
class Path < Base
