print_usage() {
cat >&2 <<USAGE
Usage: $0 vmname command arguments
Executes a command in another VM using the qubes.VMShell RPC service.  The
arguments are joined with spaces and passed to "bash -c".

Standard input and output are connected to the command.  Unlike qvm-run in Dom0,
this tool does not propagate standard error or exit codes, nor does it offer
protection against the remote VM messing with your terminal if standard output
is your terminal.

You can use \$dispvm or --dispvm instead of vmname to start a new DisposableVM.
