CDDB protocol (cddbp) servers provide compact disc information for programs
that need it. This allows such programs to display disc and track titles
automatically, and it provides extended information like liner notes and
lyrics.

This module provides a high-level Perl interface to cddbp servers. With it,
a Perl program can identify and possibly gather details about a CD based on
its "table of contents" (the disc's track times and offsets).

Disc details have been useful for generating CD catalogs, naming mp3 files,
printing CD liners, or even just playing discs in an automated jukebox.

Despite the module's name, it connects to FreeDB servers by default. This
began at version 1.04, when cddb.com changed its licensing model to support
end-user applications, not third-party libraries. Connections to cddb.com
may still work, and patches are welcome to maintain that functionality, but
it's no longer officially supported.
