-- Creates an alias for a directory and assigns the alias to the directory.
-- The alias is used to construct the access URL for the directory, such as
-- 'http:\/\/\<alias>.awsapps.com'.
--
-- After an alias has been created, it cannot be deleted or reused, so this
-- operation should only be used when absolutely necessary.
