=head1 NAME



Audio::Cuefile::Libcue



=head1 VERSION



Version 2.3.0



=head1 SYNOPSIS



Perl interface to the C cuesheet reading library



=head1 USAGE



  use Audio::Cuefile::Libcue;



  my $cuesheet = cue_from_string($string);

  print Dumper($cuesheet);



=head1 DESCRIPTION



This is a Perl interface to C, a cuesheet parsing library written in C.

C itself was forked from the C project and further enhanced.

The library can read cuesheets in many common formats.



The C interface is made available to Perl, but users should not need those.

Instead, use the one-shot parsing functions to read a cuesheet into a Perl data

structure.



=head2 Perl Interface



  my $cue = cue_from_string($string);



  # or if you have an open filehandle,

  $cue = cue_from_file($filehandle);



These two functions read a cuefile from a string or open filehandle, parse it

using the C functions, and return a hash structure.  The filehandle can be closed

after this call.



An example of the Perl usage is in F.  Note that the C and C, despite being numeric, are stored as string hash keys.  Use a numeric sort (C=E $b }>) when iterating through the keys.



=head2 C Interface



If preferred, the C functions from F are mapped into Perl functions, with the exception of C as it is automatically called when needed.  



  # Open a cuesheet

  my $cd = cue_parse_string($cue);



  print "Tracks in CD: " . cd_get_ntrack($cd) . "\n";



  $track_1 = cd_get_track( $cd, 1 );

  print "Track 1 filename: " . track_get_filename($track_1) . "\n";

  # etc



Refer to C for a list of available functions, or F for further examples.
