+ 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 Lesser 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

+ 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

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

+
+ 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

+ License. (Exception: if the Program itself is interactive but

+ 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.

-The Artistic License
-
-Preamble
-
-The intent of this document is to state the conditions under which a Package
-may be copied, such that the Copyright Holder maintains some semblance of
-artistic control over the development of the package, while giving the users of the
-package the right to use and distribute the Package in a more-or-less customary
-fashion, plus the right to make reasonable modifications.
-
-Definitions:
-
-- "Package" refers to the collection of files distributed by the Copyright
- Holder, and derivatives of that collection of files created through textual
- modification.
-- "Standard Version" refers to such a Package if it has not been modified,
- or has been modified in accordance with the wishes of the Copyright
- Holder.
-- "Copyright Holder" is whoever is named in the copyright or copyrights for
- the package.
-- "You" is you, if you're thinking about copying or distributing this Package.
-- "Reasonable copying fee" is whatever you can justify on the basis of
- media cost, duplication charges, time of people involved, and so on. (You
- will not be required to justify it to the Copyright Holder, but only to the
- computing community at large as a market that must bear the fee.)
-- "Freely Available" means that no fee is charged for the item itself, though
- there may be fees involved in handling the item. It also means that
- recipients of the item may redistribute it under the same conditions they
- received it.
-
-1. You may make and give away verbatim copies of the source form of the
-Standard Version of this Package without restriction, provided that you duplicate
-all of the original copyright notices and associated disclaimers.
-
-2. You may apply bug fixes, portability fixes and other modifications derived from
-the Public Domain or from the Copyright Holder. A Package modified in such a
-way shall still be considered the Standard Version.
-
-3. You may otherwise modify your copy of this Package in any way, provided
-that you insert a prominent notice in each changed file stating how and when
-you changed that file, and provided that you do at least ONE of the following:
-
- a) place your modifications in the Public Domain or otherwise
- make them Freely Available, such as by posting said modifications
- to Usenet or an equivalent medium, or placing the modifications on
- a major archive site such as ftp.uu.net, or by allowing the
- Copyright Holder to include your modifications in the Standard
- Version of the Package.
-
- b) use the modified Package only within your corporation or
- organization.
-
- c) rename any non-standard executables so the names do not
- conflict with standard executables, which must also be provided,
- and provide a separate manual page for each non-standard
- executable that clearly documents how it differs from the Standard
- Version.
-
- d) make other distribution arrangements with the Copyright Holder.
-
-4. You may distribute the programs of this Package in object code or executable
-form, provided that you do at least ONE of the following:
-
- a) distribute a Standard Version of the executables and library
- files, together with instructions (in the manual page or equivalent)
- on where to get the Standard Version.
-
- b) accompany the distribution with the machine-readable source of
- the Package with your modifications.
-
- c) accompany any non-standard executables with their
- corresponding Standard Version executables, giving the
- non-standard executables non-standard names, and clearly
- documenting the differences in manual pages (or equivalent),
- together with instructions on where to get the Standard Version.
-
- d) make other distribution arrangements with the Copyright Holder.
-
-5. You may charge a reasonable copying fee for any distribution of this Package.
-You may charge any fee you choose for support of this Package. You may not
-charge a fee for this Package itself. However, you may distribute this Package in
-aggregate with other (possibly commercial) programs as part of a larger
-(possibly commercial) software distribution provided that you do not advertise
-this Package as a product of your own.
-
-6. The scripts and library files supplied as input to or produced as output from
-the programs of this Package do not automatically fall under the copyright of this
-Package, but belong to whomever generated them, and may be sold
-commercially, and may be aggregated with this Package.
-
-7. C or perl subroutines supplied by you and linked into this Package shall not
-be considered part of this Package.
-
-8. The name of the Copyright Holder may not be used to endorse or promote
-products derived from this software without specific prior written permission.
-
-9. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
-IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
-WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.
-
-The End
-
-
+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

+ 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

+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.

+
+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

+
+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

+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License along
+ with this program; if not, write to the Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program

+This General Public License does not permit incorporating your program into

+consider it more useful to permit linking proprietary applications with the

+Public License instead of this License.
