|

|
|

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

file. Nothing special.

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.)

This may be a site-wide directory or a personal directory.

a few sites onto the array (just in case the first on the array won\'t

First, pick a nearby continent and country (you can pick several of

each, separated by spaces, or none if you just want to keep your

existing selections). Then, you will be presented with a list of URLs

of CPAN mirrors in the countries you selected, along with previously
|
||
|
|
selected URLs. Select some of those URLs, or just keep the old list.
|

Finally, you will be prompted for any extra URLs -- file:, ftp:, or
|
||
|
|
http: -- that host a CPAN mirror.
