-- | Contains information about an exported environment variable.
--
-- Exported environment variables are used in conjunction with CodePipeline
-- to export environment variables from the current build stage to
-- subsequent stages in the pipeline. For more information, see
-- <https://docs.aws.amazon.com/codepipeline/latest/userguide/actions-variables.html Working with variables>
-- in the /CodePipeline User Guide/.
--
-- During a build, the value of a variable is available starting with the
-- @install@ phase. It can be updated between the start of the @install@
-- phase and the end of the @post_build@ phase. After the @post_build@
-- phase ends, the value of exported variables cannot change.
