Beerware is a tongue-in-cheek software license with permissive terms, which grants the right to do anything with the source code, assuming the license notice is preserved.
Description
Should the user of the code consider the software useful, they are encouraged to buy the author a beer "in return" if they ever meet. The Humanitarian-FOSS project at Trinity College recognized the "version 42" beerware license variant as an extremely permissive "copyright only" and GPL-compatible license.[2] According to the Free Software Foundation the license would be classified as an "informal" free, non-copyleft and GPL-compatible license, however more detailed licenses are recommended.
Poul-Henning Kamp states preference of his Beerware license to other licenses, such as BSD and GPL, the latter of which he has described as a "joke".[3] The full text of Kamp's license is:[4]
/* * ---------------------------------------------------------------------------- * "THE BEER-WARE LICENSE" (Revision 42): * 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 * ---------------------------------------------------------------------------- */
