| -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.
 |
