AnnoCPAN is a web interface for the documentation of all the modules on CPAN, where users can add annotations on the margin of specific paragraphs throughout the POD. The master AnnoCPAN site is located at http://annocpan.org/. The Perl 5 module AnnoCPAN::Perldoc provides a substitute for the 'perldoc' command that displays the annotations locally and without requiring a connection to the Internet. It works by using a local note database that can be downloaded from http://annocpan.org/annopod.db
