/**
* Instance-only command which makes sure that a deployment directory seems to
* be the same when viewed from this instance as when viewed from the DAS.
*
* The DAS computes a checksum for the deployment directory as it sees it and
* passes it as a parameter to this command. This command (on each instance)
* computes a checksum for the path passed to it. If the checksums agree
* then we conclude that the DAS and this instance saw the same files in the
* directory and this command reports success; otherwise this command reports
* failure.
