=head1 SYNOPSIS

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

The default template looks like:

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

where the title is a download link.

=head1 OPTIONS

=over

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