You can get more informations on Symfony's wiki. Curious people might find a demo of the plugin on my "what?" page, and sample code usage in my links module. Thanks to my Clever Age's colleagues Tristan Rivoallan for suggestions about possible improvements, and Nicolas Perriault for the promotion of the stuff !
ps: Oh, and for those who have a RoR culture, this plugin is not a port of Rails acts_as_taggable plugin, even if I have taken certain of its concepts as a starting point.
