    ''' Used to pull a remote copy of ansible on each managed node,
        each set to run via cron and update playbook source via a source repository.
        This inverts the default *push* architecture of ansible into a *pull* architecture,
        which has near-limitless scaling potential.

None of the CLI tools are designed to run concurrently with themselves,
        you should use an external scheduler and/or locking to ensure there are no clashing operations.

The setup playbook can be tuned to change the cron frequency, logging locations, and parameters to ansible-pull.
        This is useful both for extreme scale-out as well as periodic remediation.
        Usage of the 'fetch' module to retrieve logs from ansible-pull runs would be an
        excellent way to gather and analyze remote logs from ansible-pull.
