ruby-taglib is a library that wraps taglib.  It uses dl to give access to
taglib's C library.

Taglib is available at http://developer.kde.org/~wheeler/taglib.html

To detect file types, ruby-taglib optionally uses Mahoro (
http://mahoro.rubyforge.org/ ) when available.

Example of use (with exception handling omitted):
----
require 'taglib'

file = TagLib::File.new('test.mp3')
puts "Old title: #{file.title}"

file.title = "New title"
file.save
file.close
----

For a full list of data available, see taglib.rb itself.
