The BSD Documentation License (BDL) is a content license similar to the FreeBSD Documentation License allowing flexible modification and redistribution of content. The BDL was created to contain terms more generic to other projects as well as to reintroduce the 3rd clause of the BSD license that prohibits the use of documentation for endorsement purposes.
