    18 * The VolumeActionCommand class is used to send commands which apply

    19 * to a particular volume.

    20 *

    21 * The following commands would fit into this category:

    22 *

    23 *   volume mount <volname>

    24 *   volume unmount <volname> [force]

    25 *   volume format <volname>

    26 *   volume share <volname> <method>

    27 *   volume unshare <volname> <method>

    28 *   volume shared <volname> <method>

    29 *

    30 * A typical response looks like:

    31 *

    32 *   # vdc volume unshare sdcard ums

    33 *   605 Volume sdcard /mnt/sdcard state changed from 7 (Shared-Unmounted) to 1 (Idle-Unmounted)

    34 *   200 volume operation succeeded

    35 *

    36 *   Note that the 600 series of responses are considered unsolicited and

    37 *   are dealt with directly by the VolumeManager. This command will only

    38 *   see the terminating response code (200 in the example above).

    39 *
