=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.
