Copyleft manual

Erick Iriarte from Alfa-Redi has forwarded a link to the Spanish book called "Manual del Copyleft". I have oly browsed its contents, but it looks quite impressive. It can be downloaded directly and it's released under a CC BY-SA licence (Reconocimiento-CompartirIgual 2.5 España).

Excellent online resource, particularly because there has been a marked absence of good reading material on open licences in the Spanish language.
