-- Publishes a CloudFront function by copying the function code from the
-- @DEVELOPMENT@ stage to @LIVE@. This automatically updates all cache
-- behaviors that are using this function to use the newly published copy
-- in the @LIVE@ stage.
--
-- When a function is published to the @LIVE@ stage, you can attach the
-- function to a distribution\'s cache behavior, using the function\'s
-- Amazon Resource Name (ARN).
--
-- To publish a function, you must provide the function\'s name and version
-- (@ETag@ value). To get these values, you can use @ListFunctions@ and
-- @DescribeFunction@.
