The CDDB module implements a Perl class for communicating with an audio compact disc database through the CDDBP protocol. It allows querying the database and submitting new entries to it via e-mail (the Mail::Internet and Mail::Header modules are required for submitting, but their absence won't affect other functions). Unlike its analogs, CDDB.pm doesn't try to read a disc in your CD-ROM by itself, but relies on the main program supplying disc data. Therefore, it is particularly useful for developing software that deals with alternative media, such as MPEG audio files. WWW: http://search.cpan.org/dist/CDDB/
