What is CPAN?
CPAN is an acronym standing for Comprehensive
Perl Archive Network, an archive of over ,
modules of so ware written in Perl, as well as
documentation for it.[ ] It has a presence on the
World Wide Web at www.cpan.org and is mirrored
worldwide on more than locations [ ]. CPAN can
denote either the archive network itself, or the Perl
program that acts as an interface to the network and
as an automated so ware installer (somewhat like a
package manager). Most so ware on CPAN is free
so ware.[ ]

CPAN is big
, Uploads
, Distributions
, Modules
, Uploaders

It all began a long time ago
TPC , during OSCON
In
Monterey, CA

I got annoyed
search.cpan.org was closed source (and still is)
I am not always connected to the internet
Latency

Kobesearch
I played with searching, but didn’t get very far
Randy Kobes wrote Search::CPAN::Lite
(kobesearch.cpan.org)
Needs to extract les and generates a database

Time passes
Didn’t do anything for a while
Needing to extract les and generate a database was
too much work

Needed distraction from writing a book
www.tickmyboxes.com

Insight in the shower
Do not need to extract CPAN
Indexes are good enough
Can extract on the y

Actually
Not CPAN, but MINICPAN
CPAN::Mini & minicpan
CPAN::Mini::Webserver

And
Assume we have a (MINI)CPAN mirror
