| michael@0 | 1 | BSD Protection License |
| michael@0 | 2 | February 2002 |
| michael@0 | 3 | |
| michael@0 | 4 | Preamble |
| michael@0 | 5 | -------- |
| michael@0 | 6 | |
| michael@0 | 7 | The Berkeley Software Distribution ("BSD") license has proven very effective |
| michael@0 | 8 | over the years at allowing for a wide spread of work throughout both |
| michael@0 | 9 | commercial and non-commercial products. For programmers whose primary |
| michael@0 | 10 | intention is to improve the general quality of available software, it is |
| michael@0 | 11 | arguable that there is no better license than the BSD license, as it |
| michael@0 | 12 | permits improvements to be used wherever they will help, without idealogical |
| michael@0 | 13 | or metallic constraint. |
| michael@0 | 14 | |
| michael@0 | 15 | This is of particular value to those who produce reference implementations |
| michael@0 | 16 | of proposed standards: The case of TCP/IP clearly illustrates that freely |
| michael@0 | 17 | and universally available implementations leads the rapid acceptance of |
| michael@0 | 18 | standards -- often even being used instead of a de jure standard (eg, OSI |
| michael@0 | 19 | network models). |
| michael@0 | 20 | |
| michael@0 | 21 | With the rapid proliferation of software licensed under the GNU General |
| michael@0 | 22 | Public License, however, the continued success of this role is called into |
| michael@0 | 23 | question. Given that the inclusion of a few lines of "GPL-tainted" work |
| michael@0 | 24 | into a larger body of work will result in restricted distribution -- and |
| michael@0 | 25 | given that further work will likely build upon the "tainted" portions, |
| michael@0 | 26 | making them difficult to remove at a future date -- there are inevitable |
| michael@0 | 27 | circumstances where authors would, in order to protect their goal of |
| michael@0 | 28 | providing for the widespread usage of their work, wish to guard against |
| michael@0 | 29 | such "GPL-taint". |
| michael@0 | 30 | |
| michael@0 | 31 | In addition, one can imagine that companies which operate by producing and |
| michael@0 | 32 | selling (possibly closed-source) code would wish to protect themselves |
| michael@0 | 33 | against the rise of a GPL-licensed competitor. While under existing |
| michael@0 | 34 | licenses this would mean not releasing their code under any form of open |
| michael@0 | 35 | license, if a license existed under which they could incorporate any |
| michael@0 | 36 | improvements back into their own (commercial) products then they might be |
| michael@0 | 37 | far more willing to provide for non-closed distribution. |
| michael@0 | 38 | |
| michael@0 | 39 | For the above reasons, we put forth this "BSD Protection License": A |
| michael@0 | 40 | license designed to retain the freedom granted by the BSD license to use |
| michael@0 | 41 | licensed works in a wide variety of settings, both non-commercial and |
| michael@0 | 42 | commercial, while protecting the work from having future contributors |
| michael@0 | 43 | restrict that freedom. |
| michael@0 | 44 | |
| michael@0 | 45 | The precise terms and conditions for copying, distribution, and |
| michael@0 | 46 | modification follow. |

| michael@0 | 49 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION, AND MODIFICATION |

| michael@0 | 51 | |
| michael@0 | 52 | 0. Definitions. |
| michael@0 | 53 | a) "Program", below, refers to any program or work distributed under |
| michael@0 | 54 | the terms of this license. |
| michael@0 | 55 | b) A "work based on the Program", below, refers to either the Program |
| michael@0 | 56 | or any derivative work under copyright law. |
| michael@0 | 57 | c) "Modification", below, refers to the act of creating derivative works. |
| michael@0 | 58 | d) "You", below, refers to each licensee. |
| michael@0 | 59 | |

| michael@0 | 63 | act of running the Program is not restricted, and the output from the |
| michael@0 | 64 | Program is covered only if its contents constitute a work based on the |
| michael@0 | 65 | Program. |
| michael@0 | 66 | |
| michael@0 | 67 | 2. Verbatim copies. |
| michael@0 | 68 | You may copy and distribute verbatim copies of the Program as you |
| michael@0 | 69 | receive it, in any medium, provided that you conspicuously and |
| michael@0 | 70 | appropriately publish on each copy an appropriate copyright notice; keep |
| michael@0 | 71 | intact all the notices that refer to this License and to the absence of |
| michael@0 | 72 | any warranty; and give any other recipients of the Program a copy of this |
| michael@0 | 73 | License along with the Program. |
| michael@0 | 74 | |
| michael@0 | 75 | 3. Modification and redistribution under closed license. |
| michael@0 | 76 | You may modify your copy or copies of the Program, and distribute |
| michael@0 | 77 | the resulting derivative works, provided that you meet the |
| michael@0 | 78 | following conditions: |
| michael@0 | 79 | a) The copyright notice and disclaimer on the Program must be reproduced |
| michael@0 | 80 | and included in the source code, documentation, and/or other materials |
| michael@0 | 81 | provided in a manner in which such notices are normally distributed. |
| michael@0 | 82 | b) The derivative work must be clearly identified as such, in order that |
| michael@0 | 83 | it may not be confused with the original work. |
| michael@0 | 84 | c) The license under which the derivative work is distributed must |
| michael@0 | 85 | expressly prohibit the distribution of further derivative works. |
| michael@0 | 86 | |
| michael@0 | 87 | 4. Modification and redistribution under open license. |
| michael@0 | 88 | You may modify your copy or copies of the Program, and distribute |

| michael@0 | 93 | provided in a manner in which such notices are normally distributed. |
| michael@0 | 94 | b) You must clearly indicate the nature and date of any changes made |
| michael@0 | 95 | to the Program. The full details need not necessarily be included in |
| michael@0 | 96 | the individual modified files, provided that each modified file is |
| michael@0 | 97 | clearly marked as such and instructions are included on where the |
| michael@0 | 98 | full details of the modifications may be found. |
| michael@0 | 99 | c) You must cause any work that you distribute or publish, that in whole |
| michael@0 | 100 | or in part contains or is derived from the Program or any part |
| michael@0 | 101 | thereof, to be licensed as a whole at no charge to all third |
| michael@0 | 102 | parties under the terms of this License. |
| michael@0 | 103 | |
| michael@0 | 104 | 5. Implied acceptance. |
| michael@0 | 105 | You may not copy or distribute the Program or any derivative works except |
| michael@0 | 106 | as expressly provided under this license. Consequently, any such action |
| michael@0 | 107 | will be taken as implied acceptance of the terms of this license. |
| michael@0 | 108 | |
