The Software Freedom Law Centre (SFLC), a provider of legal services to protect and advance free and open source software, has published a guide on the effective compliance with the GPL and related licences. The guide provides a basic legal overview of GPL compliance and recommends procedures that companies can implement to avoid violations. It educates the users and community of commercial distributors, redistributors, and resellers on how to avoid violations and to respond adequately and appropriately when a violation occurs. SFLC's Bradley M. Kuhn, who has conducted GPL enforcement since 1998 and co-authored the guide, added, "Cooperative and non-confrontational enforcement has always been and remains the norm and preference of everyone in the community. Through this guide, we further advance that goal by providing even more information to help those who commercialise FOSS to comply easily from the start." The guide, entitled A Practical Guide to GPL Compliance, is available at.
