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