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. + +BSD PROTECTION LICENSE +TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION, AND MODIFICATION +---------------------------------------------------------------- + +0. Definitions. + a) "Program", below, refers to any program or work distributed under + the terms of this license. + b) A "work based on the Program", below, refers to either the Program + or any derivative work under copyright law. + c) "Modification", below, refers to the act of creating derivative works. + d) "You", below, refers to each licensee. + +1. Scope. + This license governs the copying, distribution, and modification of the + Program. Other activities are outside the scope of this license; The + act of running the Program is not restricted, and the output from the + Program is covered only if its contents constitute a work based on the + Program. + +2. Verbatim copies. + You may copy and distribute verbatim copies of the Program as you + receive it, in any medium, provided that you conspicuously and + appropriately publish on each copy an appropriate copyright notice; keep + intact all the notices that refer to this License and to the absence of + any warranty; and give any other recipients of the Program a copy of this + License along with the Program. + +3. Modification and redistribution under closed license. + You may modify your copy or copies of the Program, and distribute + the resulting derivative works, provided that you meet the + following conditions: + a) The copyright notice and disclaimer on the Program must be reproduced + and included in the source code, documentation, and/or other materials + provided in a manner in which such notices are normally distributed. + b) The derivative work must be clearly identified as such, in order that + it may not be confused with the original work. + c) The license under which the derivative work is distributed must + expressly prohibit the distribution of further derivative works. + +4. Modification and redistribution under open license. + You may modify your copy or copies of the Program, and distribute + the resulting derivative works, provided that you meet the + following conditions: + a) The copyright notice and disclaimer on the Program must be reproduced + and included in the source code, documentation, and/or other materials + provided in a manner in which such notices are normally distributed. + b) You must clearly indicate the nature and date of any changes made + to the Program. The full details need not necessarily be included in + the individual modified files, provided that each modified file is + clearly marked as such and instructions are included on where the + full details of the modifications may be found. + c) You must cause any work that you distribute or publish, that in whole + or in part contains or is derived from the Program or any part + thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + +5. Implied acceptance. + You may not copy or distribute the Program or any derivative works except + as expressly provided under this license. Consequently, any such action + will be taken as implied acceptance of the terms of this license. + +6.
