| 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.) |
