The first part (up to the second use line) is a stand alone script
and this output shows that it ran.

The second part of the synopsis:
use Convert::ASN1 qw(:io);
$peer = asn_recv($sock,$buffer,0);
$nbytes = asn_read($fh, $buffer);
$nbytes = asn_send($sock, $buffer, $peer);
$nbytes = asn_send($sock, $buffer);
$nbytes = asn_write($fh, $buffer);
$buffer = asn_get($fh);
$yes = asn_ready($fh)
is not a standalone script. These are just examples of functions
exported when the :io export group is requested.
