|

|
|
|
||
|
|
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.)

The following questions are intended to help you with the

important index files and maybe keep a temporary mirror of CPAN files.

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