-- Retrieves metadata about one or more pipelines. The information
-- retrieved includes the name of the pipeline, the pipeline identifier,
-- its current state, and the user account that owns the pipeline. Using
-- account credentials, you can retrieve metadata about pipelines that you
-- or your IAM users have created. If you are using an IAM user account,
-- you can retrieve metadata about only those pipelines for which you have
-- read permissions.
--
-- To retrieve the full pipeline definition instead of metadata about the
-- pipeline, call GetPipelineDefinition.
