  return-pipe:

      Enable this option to return a shell (bash) command in the `pipe` output that can be

      The output command must be `eval`ed to return the results. It can also be passed to 
      other actions that support a `pipe` input.

      The `changed-files` output will not be populated if this option is enabled.

    default: false

outputs:
  changed-files:
    description: >
      The list of all changed files, or an empty string.

      This output is only available if the `return-pipe` option is not enabled.
