>     			    Preamble

>       The licenses for most software are designed to take away your
>     freedom to share and change it.  By contrast, the GNU 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.  This
>     General Public License applies to most of the Free Software
>     Foundation's software and to any other program whose authors commit to
>     using it.  (Some other Free Software Foundation software is covered by
>     the GNU Library General Public License instead.)  You can apply it to
>     your programs, too.

>       When we speak of free software, we are referring to freedom, not
>     price.  Our General Public Licenses are designed to make sure that you
>     have the freedom to distribute copies of free software (and charge for
>     this service if you wish), 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 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 show them these terms so they know 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.

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

>       The precise terms and conditions for copying, distribution and
>     modification follow.

>     		    GNU GENERAL PUBLIC LICENSE
>        TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

>       0. This License 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 derivative work under copyright law:
>     that is to say, a work containing the Program or a portion of it,
>     either verbatim or with modifications and/or translated into another
>     language.  (Hereinafter, translation is included without limitation in
>     the term "modification".)  Each licensee is addressed as "you".

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

>       1. 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 License and to the absence of any warranty;
>     and give any other recipients of the Program a copy of this License
>     along with the Program.

>     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.

>       2. You may modify your copy or copies of the Program or any portion
>     of it, thus forming a work based on the Program, and copy and
>     distribute such modifications or work under the terms of Section 1
>     above, provided that you also meet all of these conditions:

>         a) You must cause the modified files to carry prominent notices
>         stating that you changed the files and the date of any change.

>         b) You must cause any work that you distribute or publish, that in
>         whole or in part contains or is derived from the Program or any
>         part thereof, to be licensed as a whole at no charge to all third
>         parties under the terms of this License.

>         c) If the modified program normally reads commands interactively
>         when run, you must cause it, when started running for such
>         interactive use in the most ordinary 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
>         License.  (Exception: if the Program itself is interactive but
>         does not normally print such an announcement, your work based on
>         the Program is not required to print an announcement.)

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

>     Thus, it is not the intent of this section to claim rights or contest
>     your rights to work written entirely by you; rather, the intent is to
>     exercise the right to control the distribution of derivative or
>     collective works based on the Program.

>     In addition, mere aggregation of another work not based on the Program
>     with the Program (or with a work based on the Program) on a volume of
>     a storage or distribution medium does not bring the other work under
>     the scope of this License.

>       3. You may copy and distribute the Program (or a work based on it,
>     under Section 2) in object code or executable form under the terms of
>     Sections 1 and 2 above provided that you also do one of the following:

>         a) Accompany it with the complete corresponding machine-readable
>         source code, which must be distributed under the terms of Sections
>         1 and 2 above on a medium customarily used for software interchange; or,

>         b) Accompany it with a written offer, valid for at least three
>         years, to give any third party, for a charge no more than your
>         cost of physically performing source distribution, a complete
>         machine-readable copy of the corresponding source code, to be
>         distributed under the terms of Sections 1 and 2 above on a medium
>         customarily used for software interchange; or,

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

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

>     If distribution of executable or object code is made by offering
>     access to copy from a designated place, then offering equivalent
>     access to copy the source code from the same place counts as
>     distribution of the source code, even though third parties are not
>     compelled to copy the source along with the object code.

>       4. You may not copy, modify, sublicense, or distribute the Program
>     except as expressly provided under this License.  Any attempt
>     otherwise to copy, modify, sublicense or distribute the Program is
>     void, and will automatically terminate your rights under this License.
>     However, parties who have received copies, or rights, from you under
>     this License will not have their licenses terminated so long as such
>     parties remain in full compliance.

>       5. You are not required to accept this License, since you have not
>     signed it.  However, nothing else grants you permission to modify or
>     distribute the Program or its derivative works.  These actions are
>     prohibited by law if you do not accept this License.  Therefore, by
>     modifying or distributing 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 for copying, distributing or modifying
>     the Program or works based on it.

>       6. 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.
>     You are not responsible for enforcing compliance by third parties to
>     this License.

>       7. If, as a consequence of a court judgment or allegation of patent
>     infringement or for any other reason (not limited to patent issues),
>     conditions are imposed on you (whether by court order, agreement or
>     otherwise) that contradict the conditions of this License, they do not
>     excuse you from the conditions of this License.  If you cannot
>     distribute so as to satisfy simultaneously your obligations under this
>     License and any other pertinent obligations, then as a consequence you
>     may not distribute the Program at all.  For example, if a patent
>     license would not permit royalty-free redistribution of the Program by
>     all those who receive copies directly or indirectly through you, then
>     the only way you could satisfy both it and this License would be to
>     refrain entirely from distribution of the Program.

>     If any portion of this section is held invalid or unenforceable under
>     any particular circumstance, the balance of the section is intended to
>     apply and the section as a whole is intended to apply in other
>     circumstances.

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

>     This section is intended to make thoroughly clear what is believed to
>     be a consequence of the rest of this License.

>       8. If the distribution and/or use of the Program is restricted in
>     certain countries either by patents or by copyrighted interfaces, the
>     original copyright holder who places the Program under this License
>     may add an explicit geographical distribution limitation excluding
>     those countries, so that distribution is permitted only in or among
>     countries not thus excluded.  In such case, this License incorporates
>     the limitation as if written in the body of this License.

>       9. 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 this 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
>     this License, you may choose any version ever published by the Free Software
>     Foundation.

>       10. 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

>       11. 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.

>       12. 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.

>     		     END OF TERMS AND CONDITIONS
