This is a silly wrapper around the remctl command.
Commands are:
  $0                    - lists all VMs you can access
  $0 <vm>               - lists status of the VM named <vm>
  $0 <vm> start         - boots up the VM (alias: create)
  $0 <vm> stop          - sends a shutdown request (alias: shutdown)
  $0 <vm> force-stop    - immediately powers down the VM (alias: destroy)
  $0 <vm> force-restart - runs force-stop and then start (alias: reboot)
