NAME:
    CreateSwarmReview.py

DESCRIPTION:
    This trigger is intended for use with Swarm installations

    It will search for any jobs associated with the changelist and find any reviews
    associated with that job.
    If found it will update the review with this changelist
    Otherwise it will create a new Swarm review with a template description
    and with configurable reviewers as requested.

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

        create_swarm_review change-commit //... "python /p4/common/bin/triggers/CreateSwarmReview.py -c 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-commit //... "python /p4/common/bin/triggers/CreateSwarmReview.py -c 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.
