NAME:
    CheckSubmitHasReview.py

DESCRIPTION:
    This trigger is intended for use with Swarm installations.

    It will make sure that any changelist being submitted has an associated Swarm review.
    Note it is possible to configure a list of users who are allowed to bypass the trigger,
    e.g. a jenkins user who submits after building. See Workflow.yaml

    To install, add a line to your Perforce triggers table like the following:

        create_swarm_review change-submit //... "python /p4/common/bin/triggers/CheckSubmitHasReview.py -c /p4/common/config/Workflow.yaml -p %serverport% -u perforce %change% "

    or (if server is standard SDP and has appropriate environment defaults for P4PORT and P4USER):

        create_swarm_review change-submit //... "python /p4/common/bin/triggers/CheckSubmitHasReview.py -c /p4/common/config/Workflow.yaml %change% "

    Note that -c/--config specifies a yaml file - see Workflow.yaml for example.

    You may need to provide the full path to python executable, or edit the path to the trigger.

    Also, don't forget to make the file executable.
