| BISON GENERAL PUBLIC LICENSE |
| (Clarified 11 Feb 1988) |
| |
| Copyright (C) 1988 Richard M. Stallman |
| Everyone is permitted to copy and distribute verbatim copies |
| of this license, but changing it is not allowed. You can also |
| use this wording to make the terms for other programs. |
| |
| The license agreements of most software companies keep you at the |
| mercy of those companies. By contrast, our general public license is |
| intended to give everyone the right to share BISON. To make sure that |
| you get the rights we want you to have, we need to make restrictions |
| that forbid anyone to deny you these rights or to ask you to surrender |
| the rights. Hence this license agreement. |
| |
| Specifically, we want to make sure that you have the right to give |
| away copies of BISON, that you receive source code or else can get it |
| if you want it, that you can change BISON or use pieces of it in new |
| free programs, and that you know you can do these things. |
| |
| To make sure that everyone has such rights, we have to forbid you to |
| deprive anyone else of these rights. For example, if you distribute |
| copies of BISON, you must give the recipients all the rights that you |
| have. You must make sure that they, too, receive or can get the |
| source code. And you must tell them their rights. |
| |
| Also, for our own protection, we must make certain that everyone |
| finds out that there is no warranty for BISON. If BISON is modified by |
| someone else and passed on, we want its recipients to know that what |
| they have is not what we distributed, so that any problems introduced |
| by others will not reflect on our reputation. |
| |
| Therefore we (Richard Stallman and the Free Software Fundation, |
| Inc.) make the following terms which say what you must do to be |
| allowed to distribute or change BISON. |
| |
| |
| COPYING POLICIES |
| |
| 1. You may copy and distribute verbatim copies of BISON source code as |
| you receive it, in any medium, provided that you conspicuously and |
| appropriately publish on each copy a valid copyright notice "Copyright |
| (C) 1986 Free Software Foundation, Inc." (or with whatever year is |
| appropriate); keep intact the notices on all files that refer |
| to this License Agreement and to the absence of any warranty; and give |
| any other recipients of the BISON program a copy of this License |
| Agreement along with the program. |
| |
| 2. You may modify your copy or copies of BISON or any portion of it, |
| and copy and distribute such modifications under the terms of |
| Paragraph 1 above, provided that you also do the following: |
| |
| a) cause the modified files to carry prominent notices stating |
| that you changed the files and the date of any change; and |
| |
| b) cause the whole of any work that you distribute or publish, |
| that in whole or in part contains or is a derivative of BISON or |
| any part thereof, to be licensed at no charge to all third |
| parties on terms identical to those contained in this License |
| Agreement (except that you may choose to grant more extensive |
| warranty protection to some or all third parties, at your |
| option) |
| |
| c) You may charge a distribution fee for the physical act of |
| transferring a copy, and you may at your option offer warranty |
| protection in exchange for a fee. |
| |
| Mere aggregation of another unrelated program with this program (or its |
| derivative) on a volume of a storage or distribution medium does not bring |
| the other program under the scope of these terms. |
| |
| 3. You may copy and distribute BISON (or a portion or derivative of it, |
| under Paragraph 2) in object code or executable form under the terms of |
| Paragraphs 1 and 2 above provided that you also do one of the following: |
| |
| a) accompany it with the complete corresponding machine-readable |
| source code, which must be distributed under the terms of |
| Paragraphs 1 and 2 above; or, |
| |
| b) accompany it with a written offer, valid for at least three |
| years, to give any third party free (except for a nominal |
| shipping charge) a complete machine-readable copy of the |
| corresponding source code, to be distributed under the terms of |
| Paragraphs 1 and 2 above; or, |
| |
| c) accompany it with the information you received as to where the |
| corresponding source code may be obtained. (This alternative is |
| allowed only for noncommercial distribution and only if you |
| received the program in object code or executable form alone.) |
| |
| For an executable file, complete source code means all the source code for |
| all modules it contains; but, as a special exception, it need not include |
| source code for modules which are standard libraries that accompany the |
| operating system on which the executable file runs. |
| |
| 4. You may not copy, sublicense, distribute or transfer BISON |
| except as expressly provided under this License Agreement. Any attempt |
| otherwise to copy, sublicense, distribute or transfer BISON is void and |
| your rights to use the program under this License agreement shall be |
| automatically terminated. However, parties who have received computer |
| software programs from you with this License Agreement will not have |
| their licenses terminated so long as such parties remain in full compliance. |
| |
| 5. If you wish to incorporate parts of GNU CC into other free programs |
| whose distribution conditions are different, write to the Free Software |
| Foundation at 675 Mass Ave, Cambridge, MA 02139. We have not yet worked |
| out a simple rule that can be stated here, but we will often permit this. |
| We will be guided by the two goals of preserving the free status of all |
| derivatives of our free software and of promoting the sharing and reuse of |
| software. |
| |
| Your comments and suggestions about our licensing policies and our |
| software are welcome! Please contact the Free Software Foundation, Inc., |
| 675 Mass Ave, Cambridge, MA 02139, or call (617) 876-3296. |
| |
| In other words, go ahead and share BISON, but don't try to stop |
| anyone else from sharing it farther. Help stamp out software hoarding! |
| |
| NO WARRANTY |
| |
| BECAUSE BISON IS LICENSED FREE OF CHARGE, WE PROVIDE ABSOLUTELY NO |
| WARRANTY, TO THE EXTENT PERMITTED BY APPLICABLE STATE LAW. EXCEPT |
| WHEN OTHERWISE STATED IN WRITING, FREE SOFTWARE FOUNDATION, INC, |
| RICHARD M. STALLMAN AND/OR OTHER PARTIES PROVIDE BISON "AS IS" WITHOUT |
| WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT |
| LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR |
| A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND |
| PERFORMANCE OF BISON IS WITH YOU. SHOULD BISON PROVE DEFECTIVE, YOU |
| ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. |
| |
| IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL RICHARD M. |
| STALLMAN, THE FREE SOFTWARE FOUNDATION, INC., AND/OR ANY OTHER PARTY |
| WHO MAY MODIFY AND REDISTRIBUTE BISON AS PERMITTED ABOVE, BE LIABLE TO |
| YOU FOR DAMAGES, INCLUDING ANY LOST PROFITS, LOST MONIES, OR OTHER |
| SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR |
| INABILITY TO USE (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA |
| BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY THIRD PARTIES OR A |
| FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS) BISON, EVEN |
| IF YOU HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR |
| ANY CLAIM BY ANY OTHER PARTY. |
