Version 2, June 1991

Packit 01d647
Packit 01d647

Copyright (C) 1989, 1991 Free Software Foundation, Inc.

Packit 01d647
51 Franklin Street, 5th Floor, Boston, MA 02110-1301 USA.
Packit 01d647
Everyone is permitted to copy and distribute verbatim copies
Packit 01d647
of this license document, but changing it is not allowed.

Packit 01d647
Packit 01d647

Preamble

Packit 01d647
Packit 01d647

The licenses for most software are designed to take away your

Packit 01d647
freedom to share and change it.  By contrast, the GNU General Public
Packit 01d647
License is intended to guarantee your freedom to share and change free
Packit 01d647
software--to make sure the software is free for all its users.  This
Packit 01d647
General Public License applies to most of the Free Software
Packit 01d647
Foundation's software and to any other program whose authors commit to
Packit 01d647
using it.  (Some other Free Software Foundation software is covered by
Packit 01d647
the GNU Library General Public License instead.)  You can apply it to
Packit 01d647
your programs, too.

Packit 01d647
Packit 01d647

When we speak of free software, we are referring to freedom, not

Packit 01d647
price.  Our General Public Licenses are designed to make sure that you
Packit 01d647
have the freedom to distribute copies of free software (and charge for
Packit 01d647
this service if you wish), that you receive source code or can get it
Packit 01d647
if you want it, that you can change the software or use pieces of it
Packit 01d647
in new free programs; and that you know you can do these things.

Packit 01d647
Packit 01d647

To protect your rights, we need to make restrictions that forbid

Packit 01d647
anyone to deny you these rights or to ask you to surrender the rights.
Packit 01d647
These restrictions translate to certain responsibilities for you if you
Packit 01d647
distribute copies of the software, or if you modify it.

Packit 01d647
Packit 01d647

For example, if you distribute copies of such a program, whether

Packit 01d647
gratis or for a fee, you must give the recipients all the rights that
Packit 01d647
you have.  You must make sure that they, too, receive or can get the
Packit 01d647
source code.  And you must show them these terms so they know their
Packit 01d647
rights.

Packit 01d647
Packit 01d647

We protect your rights with two steps: (1) copyright the software, and

Packit 01d647
(2) offer you this license which gives you legal permission to copy,
Packit 01d647
distribute and/or modify the software.

Packit 01d647
Packit 01d647

Also, for each author's protection and ours, we want to make certain

Packit 01d647
that everyone understands that there is no warranty for this free
Packit 01d647
software.  If the software is modified by someone else and passed on, we
Packit 01d647
want its recipients to know that what they have is not the original, so
Packit 01d647
that any problems introduced by others will not reflect on the original
Packit 01d647
authors' reputations.

Packit 01d647
Packit 01d647

Finally, any free program is threatened constantly by software

Packit 01d647
patents.  We wish to avoid the danger that redistributors of a free
Packit 01d647
program will individually obtain patent licenses, in effect making the
Packit 01d647
program proprietary.  To prevent this, we have made it clear that any
Packit 01d647
patent must be licensed for everyone's free use or not licensed at all.

Packit 01d647
Packit 01d647

The precise terms and conditions for copying, distribution and

Packit 01d647
modification follow.

Packit 01d647
Packit 01d647

GNU General Public License

Packit 01d647
Terms And Conditions For Copying, Distribution And Modification
Packit 01d647
Packit 01d647

0. This License applies to any program or other work which contains

Packit 01d647
a notice placed by the copyright holder saying it may be distributed
Packit 01d647
under the terms of this General Public License.  The "Program", below,
Packit 01d647
refers to any such program or work, and a "work based on the Program"
Packit 01d647
means either the Program or any derivative work under copyright law:
Packit 01d647
that is to say, a work containing the Program or a portion of it,
Packit 01d647
either verbatim or with modifications and/or translated into another
Packit 01d647
language.  (Hereinafter, translation is included without limitation in
Packit 01d647
the term "modification".)  Each licensee is addressed as "you".

Packit 01d647
Packit 01d647

Activities other than copying, distribution and modification are not

Packit 01d647
covered by this License; they are outside its scope.  The act of
Packit 01d647
running the Program is not restricted, and the output from the Program
Packit 01d647
is covered only if its contents constitute a work based on the
Packit 01d647
Program (independent of having been made by running the Program).
Packit 01d647
Whether that is true depends on what the Program does.

Packit 01d647
Packit 01d647

1. You may copy and distribute verbatim copies of the Program's

Packit 01d647
source code as you receive it, in any medium, provided that you
Packit 01d647
conspicuously and appropriately publish on each copy an appropriate
Packit 01d647
copyright notice and disclaimer of warranty; keep intact all the
Packit 01d647
notices that refer to this License and to the absence of any warranty;
Packit 01d647
and give any other recipients of the Program a copy of this License
Packit 01d647
along with the Program.

Packit 01d647
Packit 01d647

You may charge a fee for the physical act of transferring a copy, and

Packit 01d647
you may at your option offer warranty protection in exchange for a fee.

Packit 01d647
Packit 01d647

2. You may modify your copy or copies of the Program or any portion

Packit 01d647
of it, thus forming a work based on the Program, and copy and
Packit 01d647
distribute such modifications or work under the terms of Section 1
Packit 01d647
above, provided that you also meet all of these conditions:

Packit 01d647
Packit 01d647
    Packit 01d647
  1. Packit 01d647

    You must cause the modified files to carry prominent notices

    Packit 01d647
    stating that you changed the files and the date of any change.

    Packit 01d647
    Packit 01d647
    Packit 01d647
  2. Packit 01d647

    You must cause any work that you distribute or publish, that in

    Packit 01d647
    whole or in part contains or is derived from the Program or any
    Packit 01d647
    part thereof, to be licensed as a whole at no charge to all third
    Packit 01d647
    parties under the terms of this License.

    Packit 01d647
    Packit 01d647
    Packit 01d647
  3. Packit 01d647

    If the modified program normally reads commands interactively

    Packit 01d647
    when run, you must cause it, when started running for such
    Packit 01d647
    interactive use in the most ordinary way, to print or display an
    Packit 01d647
    announcement including an appropriate copyright notice and a
    Packit 01d647
    notice that there is no warranty (or else, saying that you provide
    Packit 01d647
    a warranty) and that users may redistribute the program under
    Packit 01d647
    these conditions, and telling the user how to view a copy of this
    Packit 01d647
    License.  (Exception: if the Program itself is interactive but
    Packit 01d647
    does not normally print such an announcement, your work based on
    Packit 01d647
    the Program is not required to print an announcement.)

    Packit 01d647
    Packit 01d647
    Packit 01d647
    Packit 01d647

    These requirements apply to the modified work as a whole. If

    Packit 01d647
    identifiable sections of that work are not derived from the Program,
    Packit 01d647
    and can be reasonably considered independent and separate works in
    Packit 01d647
    themselves, then this License, and its terms, do not apply to those
    Packit 01d647
    sections when you distribute them as separate works.  But when you
    Packit 01d647
    distribute the same sections as part of a whole which is a work based
    Packit 01d647
    on the Program, the distribution of the whole must be on the terms of
    Packit 01d647
    this License, whose permissions for other licensees extend to the
    Packit 01d647
    entire whole, and thus to each and every part regardless of who wrote it.

    Packit 01d647
    Packit 01d647

    Thus, it is not the intent of this section to claim rights or contest

    Packit 01d647
    your rights to work written entirely by you; rather, the intent is to
    Packit 01d647
    exercise the right to control the distribution of derivative or
    Packit 01d647
    collective works based on the Program.

    Packit 01d647
    Packit 01d647

    In addition, mere aggregation of another work not based on the Program

    Packit 01d647
    with the Program (or with a work based on the Program) on a volume of
    Packit 01d647
    a storage or distribution medium does not bring the other work under
    Packit 01d647
    the scope of this License.

    Packit 01d647
    Packit 01d647

    3. You may copy and distribute the Program (or a work based on it,

    Packit 01d647
    under Section 2) in object code or executable form under the terms of
    Packit 01d647
    Sections 1 and 2 above provided that you also do one of the following:

    Packit 01d647
    Packit 01d647
      Packit 01d647
    1. Packit 01d647

      Accompany it with the complete corresponding machine-readable

      Packit 01d647
      source code, which must be distributed under the terms of Sections
      Packit 01d647
      1 and 2 above on a medium customarily used for software interchange; or,

      Packit 01d647
      Packit 01d647
      Packit 01d647
    2. Packit 01d647

      Accompany it with a written offer, valid for at least three

      Packit 01d647
      years, to give any third party, for a charge no more than your
      Packit 01d647
      cost of physically performing source distribution, a complete
      Packit 01d647
      machine-readable copy of the corresponding source code, to be
      Packit 01d647
      distributed under the terms of Sections 1 and 2 above on a medium
      Packit 01d647
      customarily used for software interchange; or,

      Packit 01d647
      Packit 01d647
      Packit 01d647
    3. Packit 01d647

      Accompany it with the information you received as to the offer

      Packit 01d647
      to distribute corresponding source code.  (This alternative is
      Packit 01d647
      allowed only for noncommercial distribution and only if you
      Packit 01d647
      received the program in object code or executable form with such
      Packit 01d647
      an offer, in accord with Subsection b above.)

      Packit 01d647
      Packit 01d647
      Packit 01d647
      Packit 01d647

      The source code for a work means the preferred form of the work for

      Packit 01d647
      making modifications to it.  For an executable work, complete source
      Packit 01d647
      code means all the source code for all modules it contains, plus any
      Packit 01d647
      associated interface definition files, plus the scripts used to
      Packit 01d647
      control compilation and installation of the executable.  However, as a
      Packit 01d647
      special exception, the source code distributed need not include
      Packit 01d647
      anything that is normally distributed (in either source or binary
      Packit 01d647
      form) with the major components (compiler, kernel, and so on) of the
      Packit 01d647
      operating system on which the executable runs, unless that component
      Packit 01d647
      itself accompanies the executable.

      Packit 01d647
      Packit 01d647

      If distribution of executable or object code is made by offering

      Packit 01d647
      access to copy from a designated place, then offering equivalent
      Packit 01d647
      access to copy the source code from the same place counts as
      Packit 01d647
      distribution of the source code, even though third parties are not
      Packit 01d647
      compelled to copy the source along with the object code.

      Packit 01d647
      Packit 01d647

      4. You may not copy, modify, sublicense, or distribute the Program

      Packit 01d647
      except as expressly provided under this License.  Any attempt
      Packit 01d647
      otherwise to copy, modify, sublicense or distribute the Program is
      Packit 01d647
      void, and will automatically terminate your rights under this License.
      Packit 01d647
      However, parties who have received copies, or rights, from you under
      Packit 01d647
      this License will not have their licenses terminated so long as such
      Packit 01d647
      parties remain in full compliance.

      Packit 01d647
      Packit 01d647

      5. You are not required to accept this License, since you have not

      Packit 01d647
      signed it.  However, nothing else grants you permission to modify or
      Packit 01d647
      distribute the Program or its derivative works.  These actions are
      Packit 01d647
      prohibited by law if you do not accept this License.  Therefore, by
      Packit 01d647
      modifying or distributing the Program (or any work based on the
      Packit 01d647
      Program), you indicate your acceptance of this License to do so, and
      Packit 01d647
      all its terms and conditions for copying, distributing or modifying
      Packit 01d647
      the Program or works based on it.

      Packit 01d647
      Packit 01d647

      6. Each time you redistribute the Program (or any work based on the

      Packit 01d647
      Program), the recipient automatically receives a license from the
      Packit 01d647
      original licensor to copy, distribute or modify the Program subject to
      Packit 01d647
      these terms and conditions.  You may not impose any further
      Packit 01d647
      restrictions on the recipients' exercise of the rights granted herein.
      Packit 01d647
      You are not responsible for enforcing compliance by third parties to
      Packit 01d647
      this License.

      Packit 01d647
      Packit 01d647

      7. If, as a consequence of a court judgment or allegation of patent

      Packit 01d647
      infringement or for any other reason (not limited to patent issues),
      Packit 01d647
      conditions are imposed on you (whether by court order, agreement or
      Packit 01d647
      otherwise) that contradict the conditions of this License, they do not
      Packit 01d647
      excuse you from the conditions of this License.  If you cannot
      Packit 01d647
      distribute so as to satisfy simultaneously your obligations under this
      Packit 01d647
      License and any other pertinent obligations, then as a consequence you
      Packit 01d647
      may not distribute the Program at all.  For example, if a patent
      Packit 01d647
      license would not permit royalty-free redistribution of the Program by
      Packit 01d647
      all those who receive copies directly or indirectly through you, then
      Packit 01d647
      the only way you could satisfy both it and this License would be to
      Packit 01d647
      refrain entirely from distribution of the Program.

      Packit 01d647
      Packit 01d647

      If any portion of this section is held invalid or unenforceable under

      Packit 01d647
      any particular circumstance, the balance of the section is intended to
      Packit 01d647
      apply and the section as a whole is intended to apply in other
      Packit 01d647
      circumstances.

      Packit 01d647
      Packit 01d647

      It is not the purpose of this section to induce you to infringe any

      Packit 01d647
      patents or other property right claims or to contest validity of any
      Packit 01d647
      such claims; this section has the sole purpose of protecting the
      Packit 01d647
      integrity of the free software distribution system, which is
      Packit 01d647
      implemented by public license practices.  Many people have made
      Packit 01d647
      generous contributions to the wide range of software distributed
      Packit 01d647
      through that system in reliance on consistent application of that
      Packit 01d647
      system; it is up to the author/donor to decide if he or she is willing
      Packit 01d647
      to distribute software through any other system and a licensee cannot
      Packit 01d647
      impose that choice.

      Packit 01d647
      Packit 01d647

      This section is intended to make thoroughly clear what is believed to

      Packit 01d647
      be a consequence of the rest of this License.

      Packit 01d647
      Packit 01d647

      8. If the distribution and/or use of the Program is restricted in

      Packit 01d647
      certain countries either by patents or by copyrighted interfaces, the
      Packit 01d647
      original copyright holder who places the Program under this License
      Packit 01d647
      may add an explicit geographical distribution limitation excluding
      Packit 01d647
      those countries, so that distribution is permitted only in or among
      Packit 01d647
      countries not thus excluded.  In such case, this License incorporates
      Packit 01d647
      the limitation as if written in the body of this License.

      Packit 01d647
      Packit 01d647

      9. The Free Software Foundation may publish revised and/or new versions

      Packit 01d647
      of the General Public License from time to time.  Such new versions will
      Packit 01d647
      be similar in spirit to the present version, but may differ in detail to
      Packit 01d647
      address new problems or concerns.

      Packit 01d647
      Packit 01d647

      Each version is given a distinguishing version number. If the Program

      Packit 01d647
      specifies a version number of this License which applies to it and "any
      Packit 01d647
      later version", you have the option of following the terms and conditions
      Packit 01d647
      either of that version or of any later version published by the Free
      Packit 01d647
      Software Foundation.  If the Program does not specify a version number of
      Packit 01d647
      this License, you may choose any version ever published by the Free Software
      Packit 01d647
      Foundation.

      Packit 01d647
      Packit 01d647

      10. If you wish to incorporate parts of the Program into other free

      Packit 01d647
      programs whose distribution conditions are different, write to the author
      Packit 01d647
      to ask for permission.  For software which is copyrighted by the Free
      Packit 01d647
      Software Foundation, write to the Free Software Foundation; we sometimes
      Packit 01d647
      make exceptions for this.  Our decision will be guided by the two goals
      Packit 01d647
      of preserving the free status of all derivatives of our free software and
      Packit 01d647
      of promoting the sharing and reuse of software generally.

      Packit 01d647
      Packit 01d647

      No Warranty

      Packit 01d647
      Packit 01d647

      11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY

      How to Apply These Terms to Your New Programs

      Packit 01d647
      Packit 01d647

      If you develop a new program, and you want it to be of the greatest

      Packit 01d647
      possible use to the public, the best way to achieve this is to make it
      Packit 01d647
      free software which everyone can redistribute and change under these
      Packit 01d647
      terms.

      Packit 01d647
      Packit 01d647
      Packit 01d647

      To do so, attach the following notices to the program. It is

      Packit 01d647
      safest to attach them to the start of each source file to most
      Packit 01d647
      effectively convey the exclusion of warranty; and each file should
      Packit 01d647
      have at least the "copyright" line and a pointer to where the full
      Packit 01d647
      notice is found.

          You should have received a copy of the GNU General Public License
      Packit 01d647
          along with this program; if not, write to the Free Software

      Packit 01d647
      Packit 01d647

      Also add information on how to contact you by electronic and paper

      Packit 01d647
      mail.

      Packit 01d647
      Packit 01d647

      If the program is interactive, make it output a short notice like this

      Packit 01d647
      when it starts in an interactive mode:

      Packit 01d647
      Packit 01d647
          Gnomovision version 69, Copyright (C) 19yy name of author
      Packit 01d647
          Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
      Packit 01d647
          This is free software, and you are welcome to redistribute it
      Packit 01d647
          under certain conditions; type `show c' for details.
      Packit 01d647
      Packit 01d647

      The hypothetical commands "show w" and "show c" should show the appropriate

      Packit 01d647
      parts of the General Public License.  Of course, the commands you use may
      Packit 01d647
      be called something other than "show w" and "show c"; they could even be
      Packit 01d647
      mouse-clicks or menu items--whatever suits your program.

      Packit 01d647
      Packit 01d647

      You should also get your employer (if you work as a programmer) or your

      Packit 01d647
      school, if any, to sign a "copyright disclaimer" for the program, if
      Packit 01d647
      necessary.  Here is a sample; alter the names:

      Packit 01d647
      Packit 01d647

      This General Public License does not permit incorporating your program into

      Packit 01d647
      proprietary programs.  If your program is a subroutine library, you may
      Packit 01d647
      consider it more useful to permit linking proprietary applications with the
      Packit 01d647
      library.  If this is what you want to do, use the GNU Library General
      Packit 01d647
      Public License instead of this License.
