193
194App::MusicExpo - script which generates a HTML table of music tags
195
196=head1 SYNOPSIS
197
198 use App::MusicExpo;
199 App::MusicExpo->run;
200
201=head1 DESCRIPTION
202
203App::MusicExpo creates a HTML table from a list of songs.
204
205The default template looks like:
206
207 | Title | Artist | Album | Genre | Track | Year | Type |
208 |---------+---------+-----------------+---------+-------+------+------|
209 | Cellule | Silence | L'autre endroit | Electro | 01/09 | 2005 | FLAC |
210
d5aa2e89
MG
211where the type is a download link. If you have multiple files with the same
212basename (such as C<cellule.flac> and C<cellule.ogg>), they will be treated
213as two versions of the same file, so a row will be created with two download
214links, one for each format.
