-  GNU GENERAL PUBLIC LICENSE
-
-Version 2, June 1991
-
-Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-
-51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA
-
-Everyone is permitted to copy and distribute verbatim copies
-
-of this license document, but changing it is not allowed.
-
-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.
