 161 =head1 NAME
 162
 163 App::MusicExpo - script which generates a HTML table of music tags
 164
 165 =head1 SYNOPSIS
 166
 167   use App::MusicExpo;
 168   App::MusicExpo->run;
 169
 170 =head1 DESCRIPTION
 171
 172 App::MusicExpo creates a HTML table from a list of songs.
 173
 174 The default template looks like:
 175
 176     | Title   | Artist  | Album           | Genre   | Track | Year | Type |
 177     |---------+---------+-----------------+---------+-------+------+------|
 178     | Cellule | Silence | L'autre endroit | Electro | 01/09 | 2005 | FLAC |
 179
 180 where the type is a download link. If you have multiple files with the same
 181 basename (such as C<cellule.flac> and C<cellule.ogg>), they will be treated
 182 as two versions of the same file, so a row will be created with two download
 183 links, one for each format.
 184
 185 =head1 OPTIONS
 186
 187 =over
 188
 189 =item B<--template> I<template>
 190
 191 Path to the HTML::Template::Compiled template used for generating the music table. If '' (empty), uses the default format. Is empty by default.
 192
 193 =item B<--prefix> I<prefix>
 194
 195 Prefix for download links. Defaults to '/music/'.
 196
 197 =item B<--cache> I<filename>
 198
 199 Path to the cache file. Created if it does not exist. If '' (empty), disables caching. Is empty by default.
