    Check for and perform pending project synchronization.

    Synchronization is automatic when Astakos is running.

    This command provides manual access to the synchronization.

    Details:

    Changes in project resources and memberships (such as approving

    a project or accepting a member into it) are changes in policy

    that are recorded in Astakos. These changes have to be synchronized

    with the quota system so that they come in effect.

    The quotaholder service must be running.

    Astakos is not required, but there should be no harm if it is

    running, even if under online traffic.
