first example

in the example on the RRDs::create stuff, the book reads:

use RRDs;
my $database = "router.rrd";

RRDs::create ($database, "-start", time, "-step", "120",

"DS:bandin:COUNTER:240:0:10000000",

"DS:bandout:COUNTER:240:0:10000000",

"DS:temp_in:GAUGE:240:0:100",

"RRA:AVERAGE:0.5:30:24");



my $ERR=RRDs::error;

die "Can't create $database: $ERR\n" if $ERR;

Unfortunately this code snippet stops with an error

Can't create router.rrd: step size should be no less than one second

.. the example should use "--start"/"--step" instead of "-start"/"-step" in order to work.
