3687
3688                             Preamble
3689
3690   The licenses for most software are designed to take away your
3691 freedom to share and change it.  By contrast, the GNU General Public
3692 License is intended to guarantee your freedom to share and change free
3693 software--to make sure the software is free for all its users.  This
3694 General Public License applies to most of the Free Software
3695 Foundation's software and to any other program whose authors commit to
3696 using it.  (Some other Free Software Foundation software is covered by
3697 the GNU Library General Public License instead.)  You can apply it to
3698 your programs, too.
3699
3700   When we speak of free software, we are referring to freedom, not
3701 price.  Our General Public Licenses are designed to make sure that you
3702 have the freedom to distribute copies of free software (and charge for
3703 this service if you wish), that you receive source code or can get it
3704 if you want it, that you can change the software or use pieces of it
3705 in new free programs; and that you know you can do these things.
3706
3707   To protect your rights, we need to make restrictions that forbid
3708 anyone to deny you these rights or to ask you to surrender the rights.
3709 These restrictions translate to certain responsibilities for you if you
3710 distribute copies of the software, or if you modify it.
3711
3712   For example, if you distribute copies of such a program, whether
3713 gratis or for a fee, you must give the recipients all the rights that
3714 you have.  You must make sure that they, too, receive or can get the
3715 source code.  And you must show them these terms so they know their
3716 rights.
3717
3718   We protect your rights with two steps: (1) copyright the software, and
3719 (2) offer you this license which gives you legal permission to copy,
3720 distribute and/or modify the software.
3721
3722   Also, for each author's protection and ours, we want to make certain
3723 that everyone understands that there is no warranty for this free
3724 software.  If the software is modified by someone else and passed on, we
3725 want its recipients to know that what they have is not the original, so
3726 that any problems introduced by others will not reflect on the original
3727 authors' reputations.
3728
3729   Finally, any free program is threatened constantly by software
3730 patents.  We wish to avoid the danger that redistributors of a free
3731 program will individually obtain patent licenses, in effect making the
3732 program proprietary.  To prevent this, we have made it clear that any
3733 patent must be licensed for everyone's free use or not licensed at all.
3734
3735   The precise terms and conditions for copying, distribution and
3736 modification follow.
3737
3738
3739                     GNU GENERAL PUBLIC LICENSE
3740    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
3741
3742   0. This License applies to any program or other work which contains
3743 a notice placed by the copyright holder saying it may be distributed
3744 under the terms of this General Public License.  The "Program", below,
3745 refers to any such program or work, and a "work based on the Program"
3746 means either the Program or any derivative work under copyright law:
3747 that is to say, a work containing the Program or a portion of it,
3748 either verbatim or with modifications and/or translated into another
3749 language.  (Hereinafter, translation is included without limitation in
3750 the term "modification".)  Each licensee is addressed as "you".
3751
3752 Activities other than copying, distribution and modification are not
3753 covered by this License; they are outside its scope.  The act of
3754 running the Program is not restricted, and the output from the Program
3755 is covered only if its contents constitute a work based on the
3756 Program (independent of having been made by running the Program).
3757 Whether that is true depends on what the Program does.
3758
3759   1. You may copy and distribute verbatim copies of the Program's
3760 source code as you receive it, in any medium, provided that you
3761 conspicuously and appropriately publish on each copy an appropriate
3762 copyright notice and disclaimer of warranty; keep intact all the
3763 notices that refer to this License and to the absence of any warranty;
3764 and give any other recipients of the Program a copy of this License
3765 along with the Program.
3766
3767 You may charge a fee for the physical act of transferring a copy, and
3768 you may at your option offer warranty protection in exchange for a fee.
3769
3770   2. You may modify your copy or copies of the Program or any portion
3771 of it, thus forming a work based on the Program, and copy and
3772 distribute such modifications or work under the terms of Section 1
3773 above, provided that you also meet all of these conditions:
3774
3775     a) You must cause the modified files to carry prominent notices
3776     stating that you changed the files and the date of any change.
3777
3778     b) You must cause any work that you distribute or publish, that in
3779     whole or in part contains or is derived from the Program or any
3780     part thereof, to be licensed as a whole at no charge to all third
3781     parties under the terms of this License.
3782
3783     c) If the modified program normally reads commands interactively
3784     when run, you must cause it, when started running for such
3785     interactive use in the most ordinary way, to print or display an
3786     announcement including an appropriate copyright notice and a
3787     notice that there is no warranty (or else, saying that you provide
3788     a warranty) and that users may redistribute the program under
3789     these conditions, and telling the user how to view a copy of this
3790     License.  (Exception: if the Program itself is interactive but
3791     does not normally print such an announcement, your work based on
3792     the Program is not required to print an announcement.)
3793
3794
3795 These requirements apply to the modified work as a whole.  If
3796 identifiable sections of that work are not derived from the Program,
3797 and can be reasonably considered independent and separate works in
3798 themselves, then this License, and its terms, do not apply to those
3799 sections when you distribute them as separate works.  But when you
3800 distribute the same sections as part of a whole which is a work based
3801 on the Program, the distribution of the whole must be on the terms of
3802 this License, whose permissions for other licensees extend to the
3803 entire whole, and thus to each and every part regardless of who wrote it.
3804
3805 Thus, it is not the intent of this section to claim rights or contest
3806 your rights to work written entirely by you; rather, the intent is to
3807 exercise the right to control the distribution of derivative or
3808 collective works based on the Program.
3809
3810 In addition, mere aggregation of another work not based on the Program
3811 with the Program (or with a work based on the Program) on a volume of
3812 a storage or distribution medium does not bring the other work under
3813 the scope of this License.
3814
3815   3. You may copy and distribute the Program (or a work based on it,
3816 under Section 2) in object code or executable form under the terms of
3817 Sections 1 and 2 above provided that you also do one of the following:
3818
3819     a) Accompany it with the complete corresponding machine-readable
3820     source code, which must be distributed under the terms of Sections
3821     1 and 2 above on a medium customarily used for software interchange; or,
3822
3823     b) Accompany it with a written offer, valid for at least three
3824     years, to give any third party, for a charge no more than your
3825     cost of physically performing source distribution, a complete
3826     machine-readable copy of the corresponding source code, to be
3827     distributed under the terms of Sections 1 and 2 above on a medium
3828     customarily used for software interchange; or,
3829
3830     c) Accompany it with the information you received as to the offer
3831     to distribute corresponding source code.  (This alternative is
3832     allowed only for noncommercial distribution and only if you
3833     received the program in object code or executable form with such
3834     an offer, in accord with Subsection b above.)
3835
3836 The source code for a work means the preferred form of the work for
3837 making modifications to it.  For an executable work, complete source
3838 code means all the source code for all modules it contains, plus any
3839 associated interface definition files, plus the scripts used to
3840 control compilation and installation of the executable.  However, as a
3841 special exception, the source code distributed need not include
3842 anything that is normally distributed (in either source or binary
3843 form) with the major components (compiler, kernel, and so on) of the
3844 operating system on which the executable runs, unless that component
3845 itself accompanies the executable.
3846
3847 If distribution of executable or object code is made by offering
3848 access to copy from a designated place, then offering equivalent
3849 access to copy the source code from the same place counts as
3850 distribution of the source code, even though third parties are not
3851 compelled to copy the source along with the object code.
3852
3853
3854   4. You may not copy, modify, sublicense, or distribute the Program
3855 except as expressly provided under this License.  Any attempt
3856 otherwise to copy, modify, sublicense or distribute the Program is
3857 void, and will automatically terminate your rights under this License.
3858 However, parties who have received copies, or rights, from you under
3859 this License will not have their licenses terminated so long as such
3860 parties remain in full compliance.
3861
3862   5. You are not required to accept this License, since you have not
3863 signed it.  However, nothing else grants you permission to modify or
3864 distribute the Program or its derivative works.  These actions are
3865 prohibited by law if you do not accept this License.  Therefore, by
3866 modifying or distributing the Program (or any work based on the
3867 Program), you indicate your acceptance of this License to do so, and
3868 all its terms and conditions for copying, distributing or modifying
3869 the Program or works based on it.
3870
3871   6. Each time you redistribute the Program (or any work based on the
3872 Program), the recipient automatically receives a license from the
3873 original licensor to copy, distribute or modify the Program subject to
3874 these terms and conditions.  You may not impose any further
3875 restrictions on the recipients' exercise of the rights granted herein.
3876 You are not responsible for enforcing compliance by third parties to
3877 this License.
3878
3879   7. If, as a consequence of a court judgment or allegation of patent
3880 infringement or for any other reason (not limited to patent issues),
3881 conditions are imposed on you (whether by court order, agreement or
3882 otherwise) that contradict the conditions of this License, they do not
3883 excuse you from the conditions of this License.  If you cannot
3884 distribute so as to satisfy simultaneously your obligations under this
3885 License and any other pertinent obligations, then as a consequence you
3886 may not distribute the Program at all.  For example, if a patent
3887 license would not permit royalty-free redistribution of the Program by
3888 all those who receive copies directly or indirectly through you, then
3889 the only way you could satisfy both it and this License would be to
3890 refrain entirely from distribution of the Program.
3891
3892 If any portion of this section is held invalid or unenforceable under
3893 any particular circumstance, the balance of the section is intended to
3894 apply and the section as a whole is intended to apply in other
3895 circumstances.
3896
3897 It is not the purpose of this section to induce you to infringe any
3898 patents or other property right claims or to contest validity of any
3899 such claims; this section has the sole purpose of protecting the
3900 integrity of the free software distribution system, which is
3901 implemented by public license practices.  Many people have made
3902 generous contributions to the wide range of software distributed
3903 through that system in reliance on consistent application of that
3904 system; it is up to the author/donor to decide if he or she is willing
3905 to distribute software through any other system and a licensee cannot
3906 impose that choice.
3907
3908 This section is intended to make thoroughly clear what is believed to
3909 be a consequence of the rest of this License.
3910
3911
3912   8. If the distribution and/or use of the Program is restricted in
3913 certain countries either by patents or by copyrighted interfaces, the
3914 original copyright holder who places the Program under this License
3915 may add an explicit geographical distribution limitation excluding
3916 those countries, so that distribution is permitted only in or among
3917 countries not thus excluded.  In such case, this License incorporates
3918 the limitation as if written in the body of this License.
3919
3920   9. The Free Software Foundation may publish revised and/or new versions
3921 of the General Public License from time to time.  Such new versions will
3922 be similar in spirit to the present version, but may differ in detail to
3923 address new problems or concerns.
3924
3925 Each version is given a distinguishing version number.  If the Program
3926 specifies a version number of this License which applies to it and "any
3927 later version", you have the option of following the terms and conditions
3928 either of that version or of any later version published by the Free
3929 Software Foundation.  If the Program does not specify a version number of
3930 this License, you may choose any version ever published by the Free Software
3931 Foundation.
3932
3933   10. If you wish to incorporate parts of the Program into other free
3934 programs whose distribution conditions are different, write to the author
3935 to ask for permission.  For software which is copyrighted by the Free
3936 Software Foundation, write to the Free Software Foundation; we sometimes
3937 make exceptions for this.  Our decision will be guided by the two goals
3938 of preserving the free status of all derivatives of our free software and
3939 of promoting the sharing and reuse of software generally.
3940
3941                             NO WARRANTY
3942
3943   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
3944 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
3945 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
3946 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
3947 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
3948 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
3949 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
3950 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
3951 REPAIR OR CORRECTION.
3952
3953   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
3954 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
3955 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
3956 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
3957 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
3958 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
3959 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
3960 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
3961 POSSIBILITY OF SUCH DAMAGES.
