-BSD Protection License
-February 2002

-Preamble
---------
-
-The Berkeley Software Distribution ("BSD") license has proven very effective
-over the years at allowing for a wide spread of work throughout both
-commercial and non-commercial products.  For programmers whose primary
-intention is to improve the general quality of available software, it is
-arguable that there is no better license than the BSD license, as it
-permits improvements to be used wherever they will help, without idealogical
-or metallic constraint.
-
-This is of particular value to those who produce reference implementations
-of proposed standards: The case of TCP/IP clearly illustrates that freely
-and universally available implementations leads the rapid acceptance of
-standards -- often even being used instead of a de jure standard (eg, OSI
-network models).
-
-With the rapid proliferation of software licensed under the GNU General
-Public License, however, the continued success of this role is called into
-question.  Given that the inclusion of a few lines of "GPL-tainted" work
-into a larger body of work will result in restricted distribution -- and
-given that further work will likely build upon the "tainted" portions,
-making them difficult to remove at a future date -- there are inevitable
-circumstances where authors would, in order to protect their goal of
-providing for the widespread usage of their work, wish to guard against
-such "GPL-taint".
-
-In addition, one can imagine that companies which operate by producing and
-selling (possibly closed-source) code would wish to protect themselves
-against the rise of a GPL-licensed competitor.  While under existing
-licenses this would mean not releasing their code under any form of open
-license, if a license existed under which they could incorporate any
-improvements back into their own (commercial) products then they might be
-far more willing to provide for non-closed distribution.
-
-For the above reasons, we put forth this "BSD Protection License": A
-license designed to retain the freedom granted by the BSD license to use
-licensed works in a wide variety of settings, both non-commercial and
-commercial, while protecting the work from having future contributors
-restrict that freedom.
-
-The precise terms and conditions for copying, distribution, and
-modification follow.
