Net::PcapWriter
perl library for easy creation of pcap files from script instead of capturing
data. Useful for testing IDS etc.
| my $w = Net::PcapWriter->new('test.pcap');
| my $conn = $w->tcp_conn('1.2.3.4',1234,'5.6.7.8',80) or die;
| $conn->write(0,"GET / HTTP/1.0 200 Ok\r\n\r\n");
| $conn->write(1,"HTTP/1.0 12345 ab\r\nContent-length: 0\r\n\r\n");
