meillo@0:  Everyone is permitted to copy and distribute verbatim copies
meillo@0:  of this license document, but changing it is not allowed.
meillo@0: 
meillo@0: 			    Preamble
meillo@0: 
meillo@0:   The licenses for most software are designed to take away your
meillo@0: freedom to share and change it.  By contrast, the GNU General Public
meillo@0: License is intended to guarantee your freedom to share and change free
meillo@0: software--to make sure the software is free for all its users.  This
meillo@0: General Public License applies to most of the Free Software
meillo@0: Foundation's software and to any other program whose authors commit to
meillo@0: using it.  (Some other Free Software Foundation software is covered by
meillo@0: the GNU Library General Public License instead.)  You can apply it to
meillo@0: your programs, too.
meillo@0: 
meillo@0:   When we speak of free software, we are referring to freedom, not
meillo@0: price.  Our General Public Licenses are designed to make sure that you
meillo@0: have the freedom to distribute copies of free software (and charge for
meillo@0: this service if you wish), that you receive source code or can get it
meillo@0: if you want it, that you can change the software or use pieces of it
meillo@0: in new free programs; and that you know you can do these things.
meillo@0: 
meillo@0:   To protect your rights, we need to make restrictions that forbid
meillo@0: anyone to deny you these rights or to ask you to surrender the rights.
meillo@0: These restrictions translate to certain responsibilities for you if you
meillo@0: distribute copies of the software, or if you modify it.
meillo@0: 
meillo@0:   For example, if you distribute copies of such a program, whether
meillo@0: gratis or for a fee, you must give the recipients all the rights that
meillo@0: you have.  You must make sure that they, too, receive or can get the
meillo@0: source code.  And you must show them these terms so they know their
meillo@0: rights.
meillo@0: 
meillo@0:   We protect your rights with two steps: (1) copyright the software, and
meillo@0: (2) offer you this license which gives you legal permission to copy,
meillo@0: distribute and/or modify the software.
meillo@0: 
meillo@0:   Also, for each author's protection and ours, we want to make certain
meillo@0: that everyone understands that there is no warranty for this free
meillo@0: software.  If the software is modified by someone else and passed on, we
meillo@0: want its recipients to know that what they have is not the original, so
meillo@0: that any problems introduced by others will not reflect on the original
meillo@0: authors' reputations.
meillo@0: 
meillo@0:   Finally, any free program is threatened constantly by software
meillo@0: patents.  We wish to avoid the danger that redistributors of a free
meillo@0: program will individually obtain patent licenses, in effect making the
meillo@0: program proprietary.  To prevent this, we have made it clear that any
meillo@0: patent must be licensed for everyone's free use or not licensed at all.
meillo@0: 
meillo@0:   The precise terms and conditions for copying, distribution and
meillo@0: modification follow.
meillo@0: 
meillo@0: 		    GNU GENERAL PUBLIC LICENSE
meillo@0:    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
meillo@0: 
meillo@0:   0. This License applies to any program or other work which contains
meillo@0: a notice placed by the copyright holder saying it may be distributed
meillo@0: under the terms of this General Public License.  The "Program", below,
meillo@0: refers to any such program or work, and a "work based on the Program"
meillo@0: means either the Program or any derivative work under copyright law:
meillo@0: that is to say, a work containing the Program or a portion of it,
meillo@0: either verbatim or with modifications and/or translated into another
meillo@0: language.  (Hereinafter, translation is included without limitation in
meillo@0: the term "modification".)  Each licensee is addressed as "you".
meillo@0: 
meillo@0: Activities other than copying, distribution and modification are not
meillo@0: covered by this License; they are outside its scope.  The act of
meillo@0: running the Program is not restricted, and the output from the Program
meillo@0: is covered only if its contents constitute a work based on the
meillo@0: Program (independent of having been made by running the Program).
meillo@0: Whether that is true depends on what the Program does.
meillo@0: 
meillo@0:   1. You may copy and distribute verbatim copies of the Program's
meillo@0: source code as you receive it, in any medium, provided that you
meillo@0: conspicuously and appropriately publish on each copy an appropriate
meillo@0: copyright notice and disclaimer of warranty; keep intact all the
meillo@0: notices that refer to this License and to the absence of any warranty;
meillo@0: and give any other recipients of the Program a copy of this License
meillo@0: along with the Program.
meillo@0: 
meillo@0: You may charge a fee for the physical act of transferring a copy, and
meillo@0: you may at your option offer warranty protection in exchange for a fee.
meillo@0: 
meillo@0:   2. You may modify your copy or copies of the Program or any portion
meillo@0: of it, thus forming a work based on the Program, and copy and
meillo@0: distribute such modifications or work under the terms of Section 1
meillo@0: above, provided that you also meet all of these conditions:
meillo@0: 
meillo@0:     a) You must cause the modified files to carry prominent notices
meillo@0:     stating that you changed the files and the date of any change.
meillo@0: 
meillo@0:     b) You must cause any work that you distribute or publish, that in
meillo@0:     whole or in part contains or is derived from the Program or any
meillo@0:     part thereof, to be licensed as a whole at no charge to all third
meillo@0:     parties under the terms of this License.
meillo@0: 
meillo@0:     c) If the modified program normally reads commands interactively
meillo@0:     when run, you must cause it, when started running for such
meillo@0:     interactive use in the most ordinary way, to print or display an
meillo@0:     announcement including an appropriate copyright notice and a
meillo@0:     notice that there is no warranty (or else, saying that you provide
meillo@0:     a warranty) and that users may redistribute the program under
meillo@0:     these conditions, and telling the user how to view a copy of this
meillo@0:     License.  (Exception: if the Program itself is interactive but
meillo@0:     does not normally print such an announcement, your work based on
meillo@0:     the Program is not required to print an announcement.)
meillo@0: 
meillo@0: These requirements apply to the modified work as a whole.  If
meillo@0: identifiable sections of that work are not derived from the Program,
meillo@0: and can be reasonably considered independent and separate works in
meillo@0: themselves, then this License, and its terms, do not apply to those
meillo@0: sections when you distribute them as separate works.  But when you
meillo@0: distribute the same sections as part of a whole which is a work based
meillo@0: on the Program, the distribution of the whole must be on the terms of
meillo@0: this License, whose permissions for other licensees extend to the
meillo@0: entire whole, and thus to each and every part regardless of who wrote it.
meillo@0: 
meillo@0: Thus, it is not the intent of this section to claim rights or contest
meillo@0: your rights to work written entirely by you; rather, the intent is to
meillo@0: exercise the right to control the distribution of derivative or
meillo@0: collective works based on the Program.
meillo@0: 
meillo@0: In addition, mere aggregation of another work not based on the Program
meillo@0: with the Program (or with a work based on the Program) on a volume of
meillo@0: a storage or distribution medium does not bring the other work under
meillo@0: the scope of this License.
meillo@0: 
meillo@0:   3. You may copy and distribute the Program (or a work based on it,
meillo@0: under Section 2) in object code or executable form under the terms of
meillo@0: Sections 1 and 2 above provided that you also do one of the following:
meillo@0: 
meillo@0:     a) Accompany it with the complete corresponding machine-readable
meillo@0:     source code, which must be distributed under the terms of Sections
meillo@0:     1 and 2 above on a medium customarily used for software interchange; or,
meillo@0: 
meillo@0:     b) Accompany it with a written offer, valid for at least three
meillo@0:     years, to give any third party, for a charge no more than your
meillo@0:     cost of physically performing source distribution, a complete
meillo@0:     machine-readable copy of the corresponding source code, to be
meillo@0:     distributed under the terms of Sections 1 and 2 above on a medium
meillo@0:     customarily used for software interchange; or,
meillo@0: 
meillo@0:     c) Accompany it with the information you received as to the offer
meillo@0:     to distribute corresponding source code.  (This alternative is
meillo@0:     allowed only for noncommercial distribution and only if you
meillo@0:     received the program in object code or executable form with such
meillo@0:     an offer, in accord with Subsection b above.)
meillo@0: 
meillo@0: The source code for a work means the preferred form of the work for
meillo@0: making modifications to it.  For an executable work, complete source
meillo@0: code means all the source code for all modules it contains, plus any
meillo@0: associated interface definition files, plus the scripts used to
meillo@0: control compilation and installation of the executable.  However, as a
meillo@0: special exception, the source code distributed need not include
meillo@0: anything that is normally distributed (in either source or binary
meillo@0: form) with the major components (compiler, kernel, and so on) of the
meillo@0: operating system on which the executable runs, unless that component
meillo@0: itself accompanies the executable.
meillo@0: 
meillo@0: If distribution of executable or object code is made by offering
meillo@0: access to copy from a designated place, then offering equivalent
meillo@0: access to copy the source code from the same place counts as
meillo@0: distribution of the source code, even though third parties are not
meillo@0: compelled to copy the source along with the object code.
meillo@0: 
meillo@0:   4. You may not copy, modify, sublicense, or distribute the Program
meillo@0: except as expressly provided under this License.  Any attempt
meillo@0: otherwise to copy, modify, sublicense or distribute the Program is
meillo@0: void, and will automatically terminate your rights under this License.
meillo@0: However, parties who have received copies, or rights, from you under
meillo@0: this License will not have their licenses terminated so long as such
meillo@0: parties remain in full compliance.
meillo@0: 
meillo@0:   5. You are not required to accept this License, since you have not
meillo@0: signed it.  However, nothing else grants you permission to modify or
meillo@0: distribute the Program or its derivative works.  These actions are
meillo@0: prohibited by law if you do not accept this License.  Therefore, by
meillo@0: modifying or distributing the Program (or any work based on the
meillo@0: Program), you indicate your acceptance of this License to do so, and
meillo@0: all its terms and conditions for copying, distributing or modifying
meillo@0: the Program or works based on it.
meillo@0: 
meillo@0:   6. Each time you redistribute the Program (or any work based on the
meillo@0: Program), the recipient automatically receives a license from the
meillo@0: original licensor to copy, distribute or modify the Program subject to
meillo@0: these terms and conditions.  You may not impose any further
meillo@0: restrictions on the recipients' exercise of the rights granted herein.
meillo@0: You are not responsible for enforcing compliance by third parties to
meillo@0: this License.
meillo@0: 
meillo@0:   7. If, as a consequence of a court judgment or allegation of patent
meillo@0: infringement or for any other reason (not limited to patent issues),
meillo@0: conditions are imposed on you (whether by court order, agreement or
meillo@0: otherwise) that contradict the conditions of this License, they do not
meillo@0: excuse you from the conditions of this License.  If you cannot
meillo@0: distribute so as to satisfy simultaneously your obligations under this
meillo@0: License and any other pertinent obligations, then as a consequence you
meillo@0: may not distribute the Program at all.  For example, if a patent
meillo@0: license would not permit royalty-free redistribution of the Program by
meillo@0: all those who receive copies directly or indirectly through you, then
meillo@0: the only way you could satisfy both it and this License would be to
meillo@0: refrain entirely from distribution of the Program.
meillo@0: 
meillo@0: If any portion of this section is held invalid or unenforceable under
meillo@0: any particular circumstance, the balance of the section is intended to
meillo@0: apply and the section as a whole is intended to apply in other
meillo@0: circumstances.
meillo@0: 
meillo@0: It is not the purpose of this section to induce you to infringe any
meillo@0: patents or other property right claims or to contest validity of any
meillo@0: such claims; this section has the sole purpose of protecting the
meillo@0: integrity of the free software distribution system, which is
meillo@0: implemented by public license practices.  Many people have made
meillo@0: generous contributions to the wide range of software distributed
meillo@0: through that system in reliance on consistent application of that
meillo@0: system; it is up to the author/donor to decide if he or she is willing
meillo@0: to distribute software through any other system and a licensee cannot
meillo@0: impose that choice.
meillo@0: 
meillo@0: This section is intended to make thoroughly clear what is believed to
meillo@0: be a consequence of the rest of this License.
meillo@0: 
meillo@0:   8. If the distribution and/or use of the Program is restricted in
meillo@0: certain countries either by patents or by copyrighted interfaces, the
meillo@0: original copyright holder who places the Program under this License
meillo@0: may add an explicit geographical distribution limitation excluding
meillo@0: those countries, so that distribution is permitted only in or among
meillo@0: countries not thus excluded.  In such case, this License incorporates
meillo@0: the limitation as if written in the body of this License.
meillo@0: 
meillo@0:   9. The Free Software Foundation may publish revised and/or new versions
meillo@0: of the General Public License from time to time.  Such new versions will
meillo@0: be similar in spirit to the present version, but may differ in detail to
meillo@0: address new problems or concerns.
meillo@0: 
meillo@0: Each version is given a distinguishing version number.  If the Program
meillo@0: specifies a version number of this License which applies to it and "any
meillo@0: later version", you have the option of following the terms and conditions
meillo@0: either of that version or of any later version published by the Free
meillo@0: Software Foundation.  If the Program does not specify a version number of
meillo@0: this License, you may choose any version ever published by the Free Software
meillo@0: Foundation.
meillo@0: 
meillo@0:   10. If you wish to incorporate parts of the Program into other free
meillo@0: programs whose distribution conditions are different, write to the author
meillo@0: to ask for permission.  For software which is copyrighted by the Free
meillo@0: Software Foundation, write to the Free Software Foundation; we sometimes
meillo@0: make exceptions for this.  Our decision will be guided by the two goals
meillo@0: of preserving the free status of all derivatives of our free software and
meillo@0: of promoting the sharing and reuse of software generally.
meillo@0: 
meillo@0: 			    NO WARRANTY
meillo@0: 
meillo@0:   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
meillo@0: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
meillo@0: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
meillo@0: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
meillo@0: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
meillo@0: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
meillo@0: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
meillo@0: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
meillo@0: REPAIR OR CORRECTION.
meillo@0: 
meillo@0:   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
meillo@0: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
meillo@0: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
meillo@0: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
meillo@0: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
meillo@0: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
meillo@0: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
meillo@0: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
meillo@0: POSSIBILITY OF SUCH DAMAGES.
meillo@0: 
meillo@0: 		     END OF TERMS AND CONDITIONS
meillo@0: 
meillo@0: 	    How to Apply These Terms to Your New Programs
meillo@0: 
meillo@0:   If you develop a new program, and you want it to be of the greatest
meillo@0: possible use to the public, the best way to achieve this is to make it
meillo@0: free software which everyone can redistribute and change under these terms.
meillo@0: 
meillo@0:   To do so, attach the following notices to the program.  It is safest
meillo@0: to attach them to the start of each source file to most effectively
meillo@0: convey the exclusion of warranty; and each file should have at least
meillo@0: the "copyright" line and a pointer to where the full notice is found.
meillo@0: 
meillo@0:     <one line to give the program's name and a brief idea of what it does.>
meillo@0:     Copyright (C) <year>  <name of author>
meillo@0: 
meillo@0:     This program is free software; you can redistribute it and/or modify
meillo@0:     it under the terms of the GNU General Public License as published by
meillo@0:     the Free Software Foundation; either version 2 of the License, or
meillo@0:     (at your option) any later version.
meillo@0: 
meillo@0:     This program is distributed in the hope that it will be useful,
meillo@0:     but WITHOUT ANY WARRANTY; without even the implied warranty of
meillo@0:     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
meillo@0:     GNU General Public License for more details.
meillo@0: 
meillo@0:     You should have received a copy of the GNU General Public License
meillo@0:     along with this program; if not, write to the Free Software
meillo@0:     Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
meillo@0: 
meillo@0: 
meillo@0: Also add information on how to contact you by electronic and paper mail.
meillo@0: 
meillo@0: If the program is interactive, make it output a short notice like this
meillo@0: when it starts in an interactive mode:
meillo@0: 
meillo@0:     Gnomovision version 69, Copyright (C) year  name of author
meillo@0:     Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
meillo@0:     This is free software, and you are welcome to redistribute it
meillo@0:     under certain conditions; type `show c' for details.
meillo@0: 
meillo@0: The hypothetical commands `show w' and `show c' should show the appropriate
meillo@0: parts of the General Public License.  Of course, the commands you use may
meillo@0: be called something other than `show w' and `show c'; they could even be
meillo@0: mouse-clicks or menu items--whatever suits your program.
meillo@0: 
meillo@0: You should also get your employer (if you work as a programmer) or your
meillo@0: school, if any, to sign a "copyright disclaimer" for the program, if
meillo@0: necessary.  Here is a sample; alter the names:
meillo@0: 
meillo@0:   Yoyodyne, Inc., hereby disclaims all copyright interest in the program
meillo@0:   `Gnomovision' (which makes passes at compilers) written by James Hacker.

meillo@0: 
meillo@0: This General Public License does not permit incorporating your program into
meillo@0: proprietary programs.  If your program is a subroutine library, you may
meillo@0: consider it more useful to permit linking proprietary applications with the
meillo@0: library.  If this is what you want to do, use the GNU Library General
meillo@0: Public License instead of this License.
