|

32 |
|

33 | The init routine asks a few questions and writes a CPAN::Config

34 | file. Nothing special.

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.

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.)
