traceroute(1) functionality in perl

 Net::Traceroute implements a parser for various traceroute implementations.
 At present, it can parse most LBL traceroute derivatives used on typical
 unixes, and the traceroute of cisco IOS. Traceroutes known not to be
 supported include that of Microsoft Windows and HP-UX.
 .
 This module has two basic modes of operation, one, where it will run
 traceroute for you, and the other where you provide text from previously
 runing traceroute to parse.
