+*
+* The VolumeActionCommand class is used to send commands which apply
+* to a particular volume.
+*
+* The following commands would fit into this category:
+*
+* volume mount <volname>
+* volume unmount <volname> [force]
+* volume format <volname>
+* volume share <volname> <method>
+* volume unshare <volname> <method>
+* volume shared <volname> <method>
+*
+* A typical response looks like:
+*
+* # vdc volume unshare sdcard ums
+* 605 Volume sdcard /mnt/sdcard state changed from 7 (Shared-Unmounted) to 1 (Idle-Unmounted)
+* 200 volume operation succeeded
+*
+* Note that the 600 series of responses are considered unsolicited and
+* are dealt with directly by the VolumeManager. This command will only
+* see the terminating response code (200 in the example above).
