 -=head2 Return values
 -
 -Unless otherwise noted the plugin answers with a line of the following form:
 -
 -I<Num> I<Message>
 -
 -If I<Num> is zero the message indicates success, if I<Num> is non-zero the
 -message indicates failure. I<Message> is a human-readable string that describes
 -the return value further.
 -
 -Commands that return values may use I<Num> to return the number of values that
 -follow, such as the B<GETVAL> command. These commands usually return a negative
 -value on failure and never return zero.
