Chris@350:                           675 Mass Ave, Cambridge, MA 02139, USA
Chris@350:  Everyone is permitted to copy and distribute verbatim copies
Chris@350:  of this license document, but changing it is not allowed.
Chris@350: 
Chris@350: 			    Preamble
Chris@350: 
Chris@350:   The licenses for most software are designed to take away your
Chris@350: freedom to share and change it.  By contrast, the GNU General Public
Chris@350: License is intended to guarantee your freedom to share and change free
Chris@350: software--to make sure the software is free for all its users.  This
Chris@350: General Public License applies to most of the Free Software
Chris@350: Foundation's software and to any other program whose authors commit to
Chris@350: using it.  (Some other Free Software Foundation software is covered by
Chris@350: the GNU Library General Public License instead.)  You can apply it to
Chris@350: your programs, too.
Chris@350: 
Chris@350:   When we speak of free software, we are referring to freedom, not
Chris@350: price.  Our General Public Licenses are designed to make sure that you
Chris@350: have the freedom to distribute copies of free software (and charge for
Chris@350: this service if you wish), that you receive source code or can get it
Chris@350: if you want it, that you can change the software or use pieces of it
Chris@350: in new free programs; and that you know you can do these things.
Chris@350: 
Chris@350:   To protect your rights, we need to make restrictions that forbid
Chris@350: anyone to deny you these rights or to ask you to surrender the rights.
Chris@350: These restrictions translate to certain responsibilities for you if you
Chris@350: distribute copies of the software, or if you modify it.
Chris@350: 
Chris@350:   For example, if you distribute copies of such a program, whether
Chris@350: gratis or for a fee, you must give the recipients all the rights that
Chris@350: you have.  You must make sure that they, too, receive or can get the
Chris@350: source code.  And you must show them these terms so they know their
Chris@350: rights.
Chris@350: 
Chris@350:   We protect your rights with two steps: (1) copyright the software, and
Chris@350: (2) offer you this license which gives you legal permission to copy,
Chris@350: distribute and/or modify the software.
Chris@350: 
Chris@350:   Also, for each author's protection and ours, we want to make certain
Chris@350: that everyone understands that there is no warranty for this free
Chris@350: software.  If the software is modified by someone else and passed on, we
Chris@350: want its recipients to know that what they have is not the original, so
Chris@350: that any problems introduced by others will not reflect on the original
Chris@350: authors' reputations.
Chris@350: 
Chris@350:   Finally, any free program is threatened constantly by software
Chris@350: patents.  We wish to avoid the danger that redistributors of a free
Chris@350: program will individually obtain patent licenses, in effect making the
Chris@350: program proprietary.  To prevent this, we have made it clear that any
Chris@350: patent must be licensed for everyone's free use or not licensed at all.
Chris@350: 
Chris@350:   The precise terms and conditions for copying, distribution and
Chris@350: modification follow.
Chris@350: 
Chris@350: 		    GNU GENERAL PUBLIC LICENSE
Chris@350:    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
Chris@350: 
Chris@350:   0. This License applies to any program or other work which contains
Chris@350: a notice placed by the copyright holder saying it may be distributed
Chris@350: under the terms of this General Public License.  The "Program", below,
Chris@350: refers to any such program or work, and a "work based on the Program"
Chris@350: means either the Program or any derivative work under copyright law:
Chris@350: that is to say, a work containing the Program or a portion of it,
Chris@350: either verbatim or with modifications and/or translated into another
Chris@350: language.  (Hereinafter, translation is included without limitation in
Chris@350: the term "modification".)  Each licensee is addressed as "you".
Chris@350: 
Chris@350: Activities other than copying, distribution and modification are not
Chris@350: covered by this License; they are outside its scope.  The act of
Chris@350: running the Program is not restricted, and the output from the Program
Chris@350: is covered only if its contents constitute a work based on the
Chris@350: Program (independent of having been made by running the Program).
Chris@350: Whether that is true depends on what the Program does.
Chris@350: 
Chris@350:   1. You may copy and distribute verbatim copies of the Program's
Chris@350: source code as you receive it, in any medium, provided that you
Chris@350: conspicuously and appropriately publish on each copy an appropriate
Chris@350: copyright notice and disclaimer of warranty; keep intact all the
Chris@350: notices that refer to this License and to the absence of any warranty;
Chris@350: and give any other recipients of the Program a copy of this License
Chris@350: along with the Program.
Chris@350: 
Chris@350: You may charge a fee for the physical act of transferring a copy, and
Chris@350: you may at your option offer warranty protection in exchange for a fee.
Chris@350: 
Chris@350:   2. You may modify your copy or copies of the Program or any portion
Chris@350: of it, thus forming a work based on the Program, and copy and
Chris@350: distribute such modifications or work under the terms of Section 1
Chris@350: above, provided that you also meet all of these conditions:
Chris@350: 
Chris@350:     a) You must cause the modified files to carry prominent notices
Chris@350:     stating that you changed the files and the date of any change.
Chris@350: 
Chris@350:     b) You must cause any work that you distribute or publish, that in
Chris@350:     whole or in part contains or is derived from the Program or any
Chris@350:     part thereof, to be licensed as a whole at no charge to all third
Chris@350:     parties under the terms of this License.
Chris@350: 
Chris@350:     c) If the modified program normally reads commands interactively
Chris@350:     when run, you must cause it, when started running for such
Chris@350:     interactive use in the most ordinary way, to print or display an
Chris@350:     announcement including an appropriate copyright notice and a
Chris@350:     notice that there is no warranty (or else, saying that you provide
Chris@350:     a warranty) and that users may redistribute the program under
Chris@350:     these conditions, and telling the user how to view a copy of this
Chris@350:     License.  (Exception: if the Program itself is interactive but
Chris@350:     does not normally print such an announcement, your work based on
Chris@350:     the Program is not required to print an announcement.)
Chris@350: 
Chris@350: These requirements apply to the modified work as a whole.  If
Chris@350: identifiable sections of that work are not derived from the Program,
Chris@350: and can be reasonably considered independent and separate works in
Chris@350: themselves, then this License, and its terms, do not apply to those
Chris@350: sections when you distribute them as separate works.  But when you
Chris@350: distribute the same sections as part of a whole which is a work based
Chris@350: on the Program, the distribution of the whole must be on the terms of
Chris@350: this License, whose permissions for other licensees extend to the
Chris@350: entire whole, and thus to each and every part regardless of who wrote it.
Chris@350: 
Chris@350: Thus, it is not the intent of this section to claim rights or contest
Chris@350: your rights to work written entirely by you; rather, the intent is to
Chris@350: exercise the right to control the distribution of derivative or
Chris@350: collective works based on the Program.
Chris@350: 
Chris@350: In addition, mere aggregation of another work not based on the Program
Chris@350: with the Program (or with a work based on the Program) on a volume of
Chris@350: a storage or distribution medium does not bring the other work under
Chris@350: the scope of this License.
Chris@350: 
Chris@350:   3. You may copy and distribute the Program (or a work based on it,
Chris@350: under Section 2) in object code or executable form under the terms of
Chris@350: Sections 1 and 2 above provided that you also do one of the following:
Chris@350: 
Chris@350:     a) Accompany it with the complete corresponding machine-readable
Chris@350:     source code, which must be distributed under the terms of Sections
Chris@350:     1 and 2 above on a medium customarily used for software interchange; or,
Chris@350: 
Chris@350:     b) Accompany it with a written offer, valid for at least three
Chris@350:     years, to give any third party, for a charge no more than your
Chris@350:     cost of physically performing source distribution, a complete
Chris@350:     machine-readable copy of the corresponding source code, to be
Chris@350:     distributed under the terms of Sections 1 and 2 above on a medium
Chris@350:     customarily used for software interchange; or,
Chris@350: 
Chris@350:     c) Accompany it with the information you received as to the offer
Chris@350:     to distribute corresponding source code.  (This alternative is
Chris@350:     allowed only for noncommercial distribution and only if you
Chris@350:     received the program in object code or executable form with such
Chris@350:     an offer, in accord with Subsection b above.)
Chris@350: 
Chris@350: The source code for a work means the preferred form of the work for
Chris@350: making modifications to it.  For an executable work, complete source
Chris@350: code means all the source code for all modules it contains, plus any
Chris@350: associated interface definition files, plus the scripts used to
Chris@350: control compilation and installation of the executable.  However, as a
Chris@350: special exception, the source code distributed need not include
Chris@350: anything that is normally distributed (in either source or binary
Chris@350: form) with the major components (compiler, kernel, and so on) of the
Chris@350: operating system on which the executable runs, unless that component
Chris@350: itself accompanies the executable.
Chris@350: 
Chris@350: If distribution of executable or object code is made by offering
Chris@350: access to copy from a designated place, then offering equivalent
Chris@350: access to copy the source code from the same place counts as
Chris@350: distribution of the source code, even though third parties are not
Chris@350: compelled to copy the source along with the object code.
Chris@350: 
Chris@350:   4. You may not copy, modify, sublicense, or distribute the Program
Chris@350: except as expressly provided under this License.  Any attempt
Chris@350: otherwise to copy, modify, sublicense or distribute the Program is
Chris@350: void, and will automatically terminate your rights under this License.
Chris@350: However, parties who have received copies, or rights, from you under
Chris@350: this License will not have their licenses terminated so long as such
Chris@350: parties remain in full compliance.
Chris@350: 
Chris@350:   5. You are not required to accept this License, since you have not
Chris@350: signed it.  However, nothing else grants you permission to modify or
Chris@350: distribute the Program or its derivative works.  These actions are
Chris@350: prohibited by law if you do not accept this License.  Therefore, by
Chris@350: modifying or distributing the Program (or any work based on the
Chris@350: Program), you indicate your acceptance of this License to do so, and
Chris@350: all its terms and conditions for copying, distributing or modifying
Chris@350: the Program or works based on it.
Chris@350: 
Chris@350:   6. Each time you redistribute the Program (or any work based on the
Chris@350: Program), the recipient automatically receives a license from the
Chris@350: original licensor to copy, distribute or modify the Program subject to
Chris@350: these terms and conditions.  You may not impose any further
Chris@350: restrictions on the recipients' exercise of the rights granted herein.
Chris@350: You are not responsible for enforcing compliance by third parties to
Chris@350: this License.
Chris@350: 
Chris@350:   7. If, as a consequence of a court judgment or allegation of patent
Chris@350: infringement or for any other reason (not limited to patent issues),
Chris@350: conditions are imposed on you (whether by court order, agreement or
Chris@350: otherwise) that contradict the conditions of this License, they do not
Chris@350: excuse you from the conditions of this License.  If you cannot
Chris@350: distribute so as to satisfy simultaneously your obligations under this
Chris@350: License and any other pertinent obligations, then as a consequence you
Chris@350: may not distribute the Program at all.  For example, if a patent
Chris@350: license would not permit royalty-free redistribution of the Program by
Chris@350: all those who receive copies directly or indirectly through you, then
Chris@350: the only way you could satisfy both it and this License would be to
Chris@350: refrain entirely from distribution of the Program.
Chris@350: 
Chris@350: If any portion of this section is held invalid or unenforceable under
Chris@350: any particular circumstance, the balance of the section is intended to
Chris@350: apply and the section as a whole is intended to apply in other
Chris@350: circumstances.
Chris@350: 
Chris@350: It is not the purpose of this section to induce you to infringe any
Chris@350: patents or other property right claims or to contest validity of any
Chris@350: such claims; this section has the sole purpose of protecting the
Chris@350: integrity of the free software distribution system, which is
Chris@350: implemented by public license practices.  Many people have made
Chris@350: generous contributions to the wide range of software distributed
Chris@350: through that system in reliance on consistent application of that
Chris@350: system; it is up to the author/donor to decide if he or she is willing
Chris@350: to distribute software through any other system and a licensee cannot
Chris@350: impose that choice.
Chris@350: 
Chris@350: This section is intended to make thoroughly clear what is believed to
Chris@350: be a consequence of the rest of this License.
Chris@350: 
Chris@350:   8. If the distribution and/or use of the Program is restricted in
Chris@350: certain countries either by patents or by copyrighted interfaces, the
Chris@350: original copyright holder who places the Program under this License
Chris@350: may add an explicit geographical distribution limitation excluding
Chris@350: those countries, so that distribution is permitted only in or among
Chris@350: countries not thus excluded.  In such case, this License incorporates
Chris@350: the limitation as if written in the body of this License.
Chris@350: 
Chris@350:   9. The Free Software Foundation may publish revised and/or new versions
Chris@350: of the General Public License from time to time.  Such new versions will
Chris@350: be similar in spirit to the present version, but may differ in detail to
Chris@350: address new problems or concerns.
Chris@350: 
Chris@350: Each version is given a distinguishing version number.  If the Program
Chris@350: specifies a version number of this License which applies to it and "any
Chris@350: later version", you have the option of following the terms and conditions
Chris@350: either of that version or of any later version published by the Free
Chris@350: Software Foundation.  If the Program does not specify a version number of
Chris@350: this License, you may choose any version ever published by the Free Software
Chris@350: Foundation.
Chris@350: 
Chris@350:   10. If you wish to incorporate parts of the Program into other free
Chris@350: programs whose distribution conditions are different, write to the author
Chris@350: to ask for permission.  For software which is copyrighted by the Free
Chris@350: Software Foundation, write to the Free Software Foundation; we sometimes
Chris@350: make exceptions for this.  Our decision will be guided by the two goals
Chris@350: of preserving the free status of all derivatives of our free software and
Chris@350: of promoting the sharing and reuse of software generally.
Chris@350: 
Chris@350: 			    NO WARRANTY
Chris@350: 
Chris@350:   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
Chris@350: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
Chris@350: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
Chris@350: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
Chris@350: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
Chris@350: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
Chris@350: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
Chris@350: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
Chris@350: REPAIR OR CORRECTION.
Chris@350: 
Chris@350:   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
Chris@350: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
Chris@350: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
Chris@350: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
Chris@350: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
Chris@350: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
Chris@350: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
Chris@350: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
Chris@350: POSSIBILITY OF SUCH DAMAGES.
Chris@350: 
Chris@350: 		     END OF TERMS AND CONDITIONS
