-- Creates a

-- from the current code and configuration of a function. Use versions to
-- create a snapshot of your function code and configuration that doesn\'t
-- change.
--
-- Lambda doesn\'t publish a version if the function\'s configuration and
-- code haven\'t changed since the last version. Use UpdateFunctionCode or
-- UpdateFunctionConfiguration to update the function before publishing a
-- version.
--
-- Clients can invoke versions directly or with an alias. To create an
-- alias, use CreateAlias.
