The FreeBSD Documentation License is the license that covers most of the documentation for the FreeBSD operating system.

License[edit]

The license is very similar to the 2-clause Simplified BSD License used by the rest of FreeBSD, however, it makes the meanings of "source code" and "compile" less ambiguous in the context of documentation. It also includes a mandatory disclaimer about IEEE and Open Group text in some manual pages.[1]

Manual Pages

Manual Pages

Some FreeBSD manual pages contain text from the IEEE Std 1003.1, 2004 Edition, Standard for 
Information Technology -- Portable Operating System Interface (POSIX®) specification. These manual 
pages are subject to the following terms:

    The Institute of Electrical and Electronics Engineers and The Open Group, have given us 
    permission to reprint portions of their documentation.

    In the following statement, the phrase ``this text'' refers to portions of the system 
    documentation.

    Portions of this text are reprinted and reproduced in electronic form in the FreeBSD manual 
    pages, from IEEE Std 1003.1, 2004 Edition, Standard for Information Technology -- 
    Portable Operating System Interface (POSIX), The Open Group Base Specifications Issue 
    6, Copyright (C) 2001-2004 by the Institute of Electrical and Electronics Engineers, Inc and 
    The Open Group. In the event of any discrepancy between these versions and the original 
    IEEE and The Open Group Standard, the original IEEE and The Open Group Standard is the 
    referee document. The original Standard can be obtained online at 
    http://www.opengroup.org/unix/online.html.

    This notice shall appear on any product containing this material.

Reception[edit]

The Free Software Foundation classes this as a free documentation license, stating that "This is a permissive non-copyleft free documentation license that is compatible with the GNU FDL."[2]

Derivatives[edit]

Based on the FreeBSD Documentation License, the BSD Documentation License was created to contain terms more generic to most projects as well as reintroducing the 3rd clause that restricts the use of documentation for endorsement purposes (as shown in the New BSD License).[citation needed]
