This is version 1.11 of Net::Traceroute. Users upgrading from before version 1.04, please note that there has been an interface change. Your program may not work. Please see "CLONING SUPPORT BEFORE 1.04" in the pod documentation. New with this version includes support for parsing traceroute text (as opposed to having to run traceroute itself), some ipv6 bug fixes, and a completely reworked test suite. Net::Traceroute is available from CPAN and my home page. My CPAN area is authors/id/H/HA/HAG, and my home page is currently http://www.linnaean.org/~hag/ . I hope you find the module useful.

"\n"; } }
