What is the BSD license?
The BSD license is another free software license that was developed by the University of California at Berkeley. It is very non-restrictive in its terms, basically allowing anyone to do anything with code covered by the license, but requiring a reference to the copyright holder in accompanying documentation — essentially requiring only credit where credit is due. This makes the license acceptable to commercial developers, but opens others to the possibility that their work may be incorporated into products that may be proprietary to someone else.
