    Everyone is permitted to copy and distribute verbatim copies
      of this license document, but changing it is not allowed.
    Preamble
    The license agreements of most software companies try to keep
      users at the mercy of those companies. By contrast, our General
      Public License is intended to guarantee your freedom to share
      and change free software--to make sure the software is free for
      all its users. The General Public License applies to the Free
      Software Foundation's software and to any other program whose
      authors commit to using it. You can use it for your programs, too.
    When we speak of free software, we are referring to freedom, not
      price. Specifically, the General Public License is designed to
      make sure that you have the freedom to give away or sell copies
      of free software, that you receive source code or can get it if
      you want it, that you can change the software or use pieces of it
      in new free programs; and that you know you can do these things.
    To protect your rights, we need to make restrictions that forbid
      anyone to deny you these rights or to ask you to surrender the
      rights. These restrictions translate to certain responsibilities for
      you if you distribute copies of the software, or if you modify it.
    For example, if you distribute copies of a such a program, whether
      gratis or for a fee, 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.
    We protect your rights with two steps: (1) copyright the
      software, and (2) offer you this license which gives you legal
      permission to copy, distribute and/or modify the software.
    Also, for each author's protection and ours, we want to make
      certain that everyone understands that there is no warranty for
      this free software. If the software is modified by someone else
      and passed on, we want its recipients to know that what they
      have is not the original, so that any problems introduced by
      others will not reflect on the original authors' reputations.
    The precise terms and conditions for copying,
      distribution and modification follow.
    GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS
      FOR COPYING, DISTRIBUTION AND MODIFICATION
    UB[947^"`
( 
        This License Agreement applies to any program or other work which
        contains a notice placed by the copyright holder saying it may
        be distributed under the terms of this General Public License.
        The "Program", below, refers to any such program or work, and
        a "work based on the Program" means either the Program or any
        work containing the Program or a portion of it, either verbatim
        or with modifications. Each licensee is addressed as "you".
      f^~(JC2\NB-U"<~p44
        You may copy and distribute verbatim copies of the Program's
        source code as you receive it, in any medium, provided that you
        conspicuously and appropriately publish on each copy an appropriate
        copyright notice and disclaimer of warranty; keep intact all the
        notices that refer to this General Public License and to the absence
        of any warranty; and give any other recipients of the Program a
        copy of this General Public License along with the Program. You
        may charge a fee for the physical act of transferring a copy.
      a9d#,gEG%5 lVcb%qL%Q
        You may modify your copy or copies of the Program 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:
        (>z0_]KFgy5JsNr-X<-
            cause the modified files to carry prominent notices stating
            that you changed the files and the date of any change; and
          L
            cause the whole of any work that you distribute or publish, that
            in whole or in part contains the Program or any part thereof,
            either with or without modifications, to be licensed at no
            charge to all third parties under the terms of this General
            Public License (except that you may choose to grant warranty
            protection to some or all third parties, at your option).
          6RtDPaBez,&
            If the modified program normally reads commands interactively
            when run, you must cause it, when started running for such
            interactive use in the simplest and most usual way, to
            print or display an announcement including an appropriate
            copyright notice and a notice that there is no warranty (or
            else, saying that you provide a warranty) and that users may
            redistribute the program under these conditions, and telling
            the user how to view a copy of this General Public License.
          !`b$o;5=P&=
            You may charge a fee for the physical act of
            transferring a copy, and you may at your option
            offer warranty protection in exchange for a fee.
        Mere aggregation of another independent work with the Program (or
          its derivative) on a volume of a storage or distribution medium
          does not bring the other work under the scope of these terms.
      3^wcE.[DP{jZD1SH5
        You may copy and distribute the Program (or a portion
        or derivative of it, under Paragraph 2) in object code
        or executable form under the terms of Paragraphs 1 and
        2 above provided that you also do one of the following:
        w8[nV.O_|%Vr,D!0!
            accompany it with the complete corresponding
            machine-readable source code, which must be distributed
            under the terms of Paragraphs 1 and 2 above; or,
          D/|5UO${K@|/f@c@ED
            accompany it with a written offer, valid for at least
            three years, to give any third party free (except for a
            nominal charge for the cost of distribution) a complete
            machine-readable copy of the corresponding source code, to be
            distributed under the terms of Paragraphs 1 and 2 above; or,
          ZQ_6[sDEG
            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.)
        Source code for a work means the preferred form of the work for
          making modifications to it. 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, or for standard header
          files or definitions files that accompany that operating system.

        You may not copy, modify, sublicense, distribute or transfer the
        Program except as expressly provided under this General Public
        License. Any attempt otherwise to copy, modify, sublicense,
        distribute or transfer the Program is void, and will automatically
        terminate your rights to use the Program under this License. However,
        parties who have received copies, or rights to use copies, from
        you under this General Public License will not have their licenses
        terminated so long as such parties remain in full compliance.
      #T[}+=	MSU8l}\U. ?5
        By copying, distributing or modifying the Program (or any
        work based on the Program) you indicate your acceptance of
        this license to do so, and all its terms and conditions.
      ZAI/k<PVH_+9Xls]
        Each time you redistribute the Program (or any work based on the
        Program), the recipient automatically receives a license from the
        original licensor to copy, distribute or modify the Program subject
        to these terms and conditions. You may not impose any further
        restrictions on the recipients' exercise of the rights granted herein.
      P}(ULsO[,En7}jfGx3	Q
        The Free Software Foundation may publish revised and/or new
        versions of the General Public License from time to time. Such
        new versions will be similar in spirit to the present version,
        but may differ in detail to address new problems or concerns.
        Each version is given a distinguishing version number. If the
          Program specifies a version number of the license which applies
          to it and "any later version", you have the option of following
          the terms and conditions either of that version or of any later
          version published by the Free Software Foundation. If the Program
          does not specify a version number of the license, you may choose
          any version ever published by the Free Software Foundation.
      
        If you wish to incorporate parts of the Program into other free
        programs whose distribution conditions are different, write to the
        author to ask for permission. For software which is copyrighted by the
        Free Software Foundation, write to the Free Software Foundation; we
        sometimes make exceptions for this. Our decision 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 generally.
      NO WARRANTY
        ][
        BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
          FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT
          WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER
          PARTIES PROVIDE THE PROGRAM "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
          THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU
          ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
      S<
        IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
        WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
        REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
        DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
        DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
        (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
        INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
        THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER
        OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
