# Versioners set env['api.version'] when a version is defined on an API and
# on the requests. The current methods for determining version are:
#
#   :header - version from HTTP Accept header.
#   :accept_version_header - version from HTTP Accept-Version header
#   :path   - version from uri. e.g. /v1/resource
#   :param  - version from uri query string, e.g. /v1/resource?apiver=v1
# See individual classes for details.
