30 | |
31 | =head1 DESCRIPTION |
32 | |
33 | The init routine asks a few questions and writes a CPAN::Config |
34 | file. Nothing special. |

60 | CPAN is the world-wide archive of perl resources. It consists of about |
61 | 100 sites that all replicate the same contents all around the globe. |
62 | Many countries have at least one CPAN site already. The resources |
63 | found on CPAN are easily accessible with the CPAN.pm module. If you |
64 | want to use CPAN.pm, you have to configure it properly. |
65 | |
66 | If you do not want to enter a dialog now, you can answer 'no' to this |
67 | question and I\'ll try to autoconfigure. (Note: you can revisit this |
68 | dialog anytime later by typing 'o conf init' at the cpan prompt.) |

224 | the charset does not matter much, but some of the aliens out there who |
225 | upload their software to CPAN bear names that are outside the ASCII |
226 | range. If your terminal supports UTF-8, you should say no to the next |
227 | question. If it supports ISO-8859-1 (also known as LATIN1) then you |
228 | should say yes. If it supports neither, your answer does not matter |
