59 | CPAN is the world-wide archive of perl resources. It consists of about | |
60 | 100 sites that all replicate the same contents all around the globe. | |
61 | Many countries have at least one CPAN site already. The resources | |
62 | found on CPAN are easily accessible with the CPAN.pm module. If you | |
63 | want to use CPAN.pm, you have to configure it properly. | |
64 | ||
65 | If you do not want to enter a dialog now, you can answer 'no' to this | |
66 | question and I\'ll try to autoconfigure. (Note: you can revisit this | |
67 | dialog anytime later by typing 'o conf init' at the cpan prompt.) | |
