197
198App::MusicExpo - script which generates a HTML table of music tags
199
200=head1 SYNOPSIS
201
202 use App::MusicExpo;
203 App::MusicExpo->run;
204
205=head1 DESCRIPTION
206
207App::MusicExpo creates a HTML table from a list of songs.
208
209The default template looks like:
210
211 | Title | Artist | Album | Genre | Track | Year | Type |
212 |---------+---------+-----------------+---------+-------+------+------|
213 | Cellule | Silence | L'autre endroit | Electro | 01/09 | 2005 | FLAC |
214
d5aa2e89
MG
215where the type is a download link. If you have multiple files with the same
216basename (such as C<cellule.flac> and C<cellule.ogg>), they will be treated
217as two versions of the same file, so a row will be created with two download
218links, one for each format.
