NAME
    CDDB::File - Parse a CDDB/freedb data file

SYNOPSIS
      my $disc = CDDB::File->new("rock/f4109511");

      print $disc->id, $disc->all_ids;
      print $disc->artist, $disc->title;
      print $disc->year, $disc->genre, $disc->extd;
      print $disc->length, $disc->track_count;

      print $disc->revision, $disc->submitted_via, $disc->processed_by;

      foreach my $track ($disc->tracks) {
        print $track->number, $track->title, $track->artist;
        print $track->length, $track->extd;
      }

DESCRIPTION
    This module provides an interface for extracting data from CDDB-format data files, as used by
    freedb.

    It does not read data from your CD, or submit information to freedb.

METHODS
  new
      my $disc = CDDB::File->new("rock/f4109511");

    This will create a new object representing the data in the file name specified.

  id / all_ids
      my $discid = $disc->id;
      my @discid = $disc->all_ids;

    Due to how freedb works, one CD may have several IDs associated with it. 'id' will return the
    first of these (not necessarily related to the filename from which this was read), whilst
    'all_ids' will return all of them.

  title / artist
    The title and artist of this CD. For eponymous CDs these will be identical, even if the data
    file leaves the artist field blank.

  year
    The (4-digit) year of release.

  genre
    The genre of this CD. This is the genre as stored in the data file itself, which is not related
    to the 11 main freedb genres.

  extd
    The "extended data" for the CD. This is used for storing miscellaneous information which has no
    better storage place, and can be of any length.

  length
    The run time of the CD in seconds.

  track_count
    The number of tracks on the CD.

  revision
    Each time information regarding the CD is updated this revision number is incremented. This
    returns the revision number of this version.

  processed_by / submitted_via
    The software which submitted this information to freedb and which processed it at the other end.

  tracks
      foreach my $track ($disc->tracks) {
        print $track->number, $track->title, $track->artist;
        print $track->length, $track->extd;
      }

    Returns a list of Track objects, each of which knows its number (numering from 1), title, length
    (in seconds), offset, and may also have extended track data.

    Tracks may also contain an 'artist' field. If this is not set the artist method will return the
    artist of the CD.
