The mirror that was fast then might not be fast now, especially if you changed hemispheres. This program goes through the F<MIRRORED.BY> file and pings a selection of mirrors on each continent to find the fastest mirrors. From the best continent, it samples several mirrors to find the URL you should add to your configuration. If you don't have a F<MIRRORED.BY> file, this program will download one for you. It looks through your existing C<urllist> configuration and then default locations. It stores it in C<~/.cpan> (or your configured location to store files). =head1 TO DO =over 4 =item * Add an option to update the CPAN configuration =item * Add an option to give JSON output =back =head1 AUTHOR brian d foy C<< <bdfoy@cpan.org> >> =head1 LICENSE This program is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
