class CodeReviewActionController(Component):
    """Support for simple code reviews.

    The action that supports the `code_review` operation will present
    an extra choice for the review decision. Depending on that decision,
    a specific state will be selected.

    Example (from the enterprise-review-workflow.ini):
    review = in_review -> * = review as
    review.operations = code_review
    review.code_review =
      approve -> in_QA,
      approve as noted -> post_review,
      request changes -> in_work
    Don't forget to add the `CodeReviewActionController` to the workflow
    option in the `[ticket]` section in TracIni.
    If there is no other workflow option, the line will look like this:
    workflow = ConfigurableTicketWorkflow,CodeReviewActionController
