Usage: %s command <params>
initialise [dev] [[ext_size]] - init. a physcial partition to store vd's
create [size] [[expiry]] - allocate a vd of specified size (and expiry)
enlarge [vdid] [extra_size] - enlarge a specified vd by some amount
delete [vdid] - delete a vd
import [filename] [[expiry]] - create a vd and populate w/ image from file
export [vdid] [filename] - copy vd's contents to a file
setexpiry [vdid] [[expiry]] - update the expiry time for a vd
list - list all the unexpired virtual disks
undelete [vdid] [[expiry]] - attempts to recover an expired vd
freespace - print out the amount of space in free pool
notes:
vdid - the virtual disk's identity string
size - measured in MB
expiry - is the expiry time of the virtual disk in seconds from now
(0 = don't expire)
device - physical partition to 'format' to hold vd's. e.g. hda4
