Beerware is a somewhat tongue-in-cheek term for software released under a very relaxed license (beerware licensed software). It provides the end user with the right to use a particular program (or do anything else with the source code).[1]

Description[edit]

Should the user of the product meet the author and consider the software useful, they are encouraged to either buy the author a beer "in return" or drink one themselves. The Fedora project recognized the "version 42" beerware license variant as extremely permissive "Copyright only" Free and GPL compatible.[2]

Many variations on the beerware model have been created. Poul-Henning Kamp's beerware license is simple and short, in contrast to the GPL, which he has described as a "joke".[3] The full text of Kamp's license is:[4]

/*
 * ----------------------------------------------------------------------------
 * "THE BEER-WARE LICENSE" (Revision 42):
 * <phk@FreeBSD.ORG> wrote this file.  As long as you retain this notice you
 * can do whatever you want with this stuff. If we meet some day, and you think
 * this stuff is worth it, you can buy me a beer in return.   Poul-Henning Kamp
