=head1 NAME

App::MusicExpo - script which generates a HTML table of music tags

=head1 SYNOPSIS

  use App::MusicExpo;
  App::MusicExpo->run;

=head1 DESCRIPTION

App::MusicExpo creates a HTML table from a list of songs.

The default template looks like:

    | Title   | Artist  | Album           | Genre   | Track | Year | Type |
    |---------+---------+-----------------+---------+-------+------+------|
    | Cellule | Silence | L'autre endroit | Electro | 01/09 | 2005 | FLAC |

where the type is a download link. If you have multiple files with the same
basename (such as C<cellule.flac> and C<cellule.ogg>), they will be treated
as two versions of the same file, so a row will be created with two download
links, one for each format.

=head1 OPTIONS

=over

=item B<--template> I<template>

Path to the HTML::Template::Compiled template used for generating the music table. If '' (empty), uses the default format. Is empty by default.

=item B<--prefix> I<prefix>

Prefix for download links. Defaults to '/music/'.

=item B<--cache> I<filename>

Path to the cache file. Created if it does not exist. If '' (empty), disables caching. Is empty by default.
