//                        Version 3, 29 June 2007
// 
//  Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
//  Everyone is permitted to copy and distribute verbatim copies
//  of this license document, but changing it is not allowed.
// 
//                             Preamble
// 
//   The GNU General Public License is a free, copyleft license for
// software and other kinds of works.
// 
//   The licenses for most software and other practical works are designed
// to take away your freedom to share and change the works.  By contrast,
// the GNU General Public License is intended to guarantee your freedom to
// share and change all versions of a program--to make sure it remains free
// software for all its users.  We, the Free Software Foundation, use the
// GNU General Public License for most of our software; it applies also to
// any other work released this way by its authors.  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
// them 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 prevent others from denying you
// these rights or asking you to surrender the rights.  Therefore, you have
// certain responsibilities if you distribute copies of the software, or if
// you modify it: responsibilities to respect the freedom of others.
// 
//   For example, if you distribute copies of such a program, whether
// gratis or for a fee, you must pass on to the recipients the same
// freedoms that you received.  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.
// 
//   Developers that use the GNU GPL protect your rights with two steps:
// (1) assert copyright on the software, and (2) offer you this License
// giving you legal permission to copy, distribute and/or modify it.
// 
//   For the developers' and authors' protection, the GPL clearly explains
// that there is no warranty for this free software.  For both users' and
// authors' sake, the GPL requires that modified versions be marked as
// changed, so that their problems will not be attributed erroneously to
// authors of previous versions.
// 
//   Some devices are designed to deny users access to install or run
// modified versions of the software inside them, although the manufacturer
// can do so.  This is fundamentally incompatible with the aim of
// protecting users' freedom to change the software.  The systematic
// pattern of such abuse occurs in the area of products for individuals to
// use, which is precisely where it is most unacceptable.  Therefore, we
// have designed this version of the GPL to prohibit the practice for those
// products.  If such problems arise substantially in other domains, we
// stand ready to extend this provision to those domains in future versions
// of the GPL, as needed to protect the freedom of users.
// 
//   Finally, every program is threatened constantly by software patents.
// States should not allow patents to restrict development and use of
// software on general-purpose computers, but in those that do, we wish to
// avoid the special danger that patents applied to a free program could
// make it effectively proprietary.  To prevent this, the GPL assures that
// patents cannot be used to render the program non-free.
// 
//   The precise terms and conditions for copying, distribution and
// modification follow.
// 
//                        TERMS AND CONDITIONS
// 
//   0. Definitions.
// 
//   "This License" refers to version 3 of the GNU General Public License.
// 
//   "Copyright" also means copyright-like laws that apply to other kinds of
// works, such as semiconductor masks.
// 
//   "The Program" refers to any copyrightable work licensed under this
// License.  Each licensee is addressed as "you".  "Licensees" and
// "recipients" may be individuals or organizations.
// 
//   To "modify" a work means to copy from or adapt all or part of the work
// in a fashion requiring copyright permission, other than the making of an
// exact copy.  The resulting work is called a "modified version" of the
// earlier work or a work "based on" the earlier work.
// 
//   A "covered work" means either the unmodified Program or a work based
// on the Program.
// 
//   To "propagate" a work means to do anything with it that, without
// permission, would make you directly or secondarily liable for
// infringement under applicable copyright law, except executing it on a
// computer or modifying a private copy.  Propagation includes copying,
// distribution (with or without modification), making available to the
// public, and in some countries other activities as well.
// 
//   To "convey" a work means any kind of propagation that enables other
// parties to make or receive copies.  Mere interaction with a user through
// a computer network, with no transfer of a copy, is not conveying.
// 
//   An interactive user interface displays "Appropriate Legal Notices"
// to the extent that it includes a convenient and prominently visible
// feature that (1) displays an appropriate copyright notice, and (2)
// tells the user that there is no warranty for the work (except to the
// extent that warranties are provided), that licensees may convey the
// work under this License, and how to view a copy of this License.  If
// the interface presents a list of user commands or options, such as a
// menu, a prominent item in the list meets this criterion.
// 
//   1. Source Code.
// 
//   The "source code" for a work means the preferred form of the work
// for making modifications to it.  "Object code" means any non-source
// form of a work.
// 
//   A "Standard Interface" means an interface that either is an official
// standard defined by a recognized standards body, or, in the case of
// interfaces specified for a particular programming language, one that
// is widely used among developers working in that language.
// 
//   The "System Libraries" of an executable work include anything, other
// than the work as a whole, that (a) is included in the normal form of
// packaging a Major Component, but which is not part of that Major
// Component, and (b) serves only to enable use of the work with that
// Major Component, or to implement a Standard Interface for which an
// implementation is available to the public in source code form.  A
// "Major Component", in this context, means a major essential component
// (kernel, window system, and so on) of the specific operating system
// (if any) on which the executable work runs, or a compiler used to
// produce the work, or an object code interpreter used to run it.
// 
//   The "Corresponding Source" for a work in object code form means all
// the source code needed to generate, install, and (for an executable
// work) run the object code and to modify the work, including scripts to
// control those activities.  However, it does not include the work's
// System Libraries, or general-purpose tools or generally available free
// programs which are used unmodified in performing those activities but
// which are not part of the work.  For example, Corresponding Source
// includes interface definition files associated with source files for
// the work, and the source code for shared libraries and dynamically
// linked subprograms that the work is specifically designed to require,
// such as by intimate data communication or control flow between those
// subprograms and other parts of the work.
// 
//   The Corresponding Source need not include anything that users
// can regenerate automatically from other parts of the Corresponding
// Source.
// 
//   The Corresponding Source for a work in source code form is that
// same work.
// 
//   2. Basic Permissions.
// 
//   All rights granted under this License are granted for the term of
// copyright on the Program, and are irrevocable provided the stated
// conditions are met.  This License explicitly affirms your unlimited
// permission to run the unmodified Program.  The output from running a
// covered work is covered by this License only if the output, given its
// content, constitutes a covered work.  This License acknowledges your
// rights of fair use or other equivalent, as provided by copyright law.
// 
//   You may make, run and propagate covered works that you do not
// convey, without conditions so long as your license otherwise remains
// in force.  You may convey covered works to others for the sole purpose
// of having them make modifications exclusively for you, or provide you
// with facilities for running those works, provided that you comply with
// the terms of this License in conveying all material for which you do
// not control copyright.  Those thus making or running the covered works
// for you must do so exclusively on your behalf, under your direction
// and control, on terms that prohibit them from making any copies of
// your copyrighted material outside their relationship with you.
// 
//   Conveying under any other circumstances is permitted solely under
// the conditions stated below.  Sublicensing is not allowed; section 10
// makes it unnecessary.
// 
//   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
// 
//   No covered work shall be deemed part of an effective technological
// measure under any applicable law fulfilling obligations under article
// 11 of the WIPO copyright treaty adopted on 20 December 1996, or
// similar laws prohibiting or restricting circumvention of such
// measures.
// 
//   When you convey a covered work, you waive any legal power to forbid
// circumvention of technological measures to the extent such circumvention
// is effected by exercising rights under this License with respect to
// the covered work, and you disclaim any intention to limit operation or
// modification of the work as a means of enforcing, against the work's
// users, your or third parties' legal rights to forbid circumvention of
// technological measures.
// 
//   4. Conveying Verbatim Copies.
// 
//   You may convey 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;
// keep intact all notices stating that this License and any
// non-permissive terms added in accord with section 7 apply to the code;
// keep intact all notices of the absence of any warranty; and give all
// recipients a copy of this License along with the Program.
// 
//   You may charge any price or no price for each copy that you convey,
// and you may offer support or warranty protection for a fee.
// 
//   5. Conveying Modified Source Versions.
// 
//   You may convey a work based on the Program, or the modifications to
// produce it from the Program, in the form of source code under the
// terms of section 4, provided that you also meet all of these conditions:
// 
//     a) The work must carry prominent notices stating that you modified
//     it, and giving a relevant date.
// 
//     b) The work must carry prominent notices stating that it is
//     released under this License and any conditions added under section
//     7.  This requirement modifies the requirement in section 4 to
//     "keep intact all notices".
// 
//     c) You must license the entire work, as a whole, under this
//     License to anyone who comes into possession of a copy.  This
//     License will therefore apply, along with any applicable section 7
//     additional terms, to the whole of the work, and all its parts,
//     regardless of how they are packaged.  This License gives no
//     permission to license the work in any other way, but it does not
//     invalidate such permission if you have separately received it.
// 
//     d) If the work has interactive user interfaces, each must display
//     Appropriate Legal Notices; however, if the Program has interactive
//     interfaces that do not display Appropriate Legal Notices, your
//     work need not make them do so.
// 
//   A compilation of a covered work with other separate and independent
// works, which are not by their nature extensions of the covered work,
// and which are not combined with it such as to form a larger program,
// in or on a volume of a storage or distribution medium, is called an
// "aggregate" if the compilation and its resulting copyright are not
// used to limit the access or legal rights of the compilation's users
// beyond what the individual works permit.  Inclusion of a covered work
// in an aggregate does not cause this License to apply to the other
// parts of the aggregate.
// 
//   6. Conveying Non-Source Forms.
// 
//   You may convey a covered work in object code form under the terms
// of sections 4 and 5, provided that you also convey the
// machine-readable Corresponding Source under the terms of this License,
// in one of these ways:
// 
//     a) Convey the object code in, or embodied in, a physical product
//     (including a physical distribution medium), accompanied by the
//     Corresponding Source fixed on a durable physical medium
//     customarily used for software interchange.
// 
//     b) Convey the object code in, or embodied in, a physical product
//     (including a physical distribution medium), accompanied by a
//     written offer, valid for at least three years and valid for as
//     long as you offer spare parts or customer support for that product
//     model, to give anyone who possesses the object code either (1) a
//     copy of the Corresponding Source for all the software in the
//     product that is covered by this License, on a durable physical
//     medium customarily used for software interchange, for a price no
//     more than your reasonable cost of physically performing this
//     conveying of source, or (2) access to copy the
//     Corresponding Source from a network server at no charge.
// 
//     c) Convey individual copies of the object code with a copy of the
//     written offer to provide the Corresponding Source.  This
//     alternative is allowed only occasionally and noncommercially, and
//     only if you received the object code with such an offer, in accord
//     with subsection 6b.
// 
//     d) Convey the object code by offering access from a designated
//     place (gratis or for a charge), and offer equivalent access to the
//     Corresponding Source in the same way through the same place at no
//     further charge.  You need not require recipients to copy the
//     Corresponding Source along with the object code.  If the place to
//     copy the object code is a network server, the Corresponding Source
//     may be on a different server (operated by you or a third party)
//     that supports equivalent copying facilities, provided you maintain
//     clear directions next to the object code saying where to find the
//     Corresponding Source.  Regardless of what server hosts the
//     Corresponding Source, you remain obligated to ensure that it is
//     available for as long as needed to satisfy these requirements.
// 
//     e) Convey the object code using peer-to-peer transmission, provided
//     you inform other peers where the object code and Corresponding
//     Source of the work are being offered to the general public at no
//     charge under subsection 6d.
// 
//   A separable portion of the object code, whose source code is excluded
// from the Corresponding Source as a System Library, need not be
// included in conveying the object code work.
// 
//   A "User Product" is either (1) a "consumer product", which means any
// tangible personal property which is normally used for personal, family,
// or household purposes, or (2) anything designed or sold for incorporation
// into a dwelling.  In determining whether a product is a consumer product,
// doubtful cases shall be resolved in favor of coverage.  For a particular
// product received by a particular user, "normally used" refers to a
// typical or common use of that class of product, regardless of the status
// of the particular user or of the way in which the particular user
// actually uses, or expects or is expected to use, the product.  A product
// is a consumer product regardless of whether the product has substantial
// commercial, industrial or non-consumer uses, unless such uses represent
// the only significant mode of use of the product.
// 
//   "Installation Information" for a User Product means any methods,
// procedures, authorization keys, or other information required to install
// and execute modified versions of a covered work in that User Product from
// a modified version of its Corresponding Source.  The information must
// suffice to ensure that the continued functioning of the modified object
// code is in no case prevented or interfered with solely because
// modification has been made.
// 
//   If you convey an object code work under this section in, or with, or
// specifically for use in, a User Product, and the conveying occurs as
// part of a transaction in which the right of possession and use of the
// User Product is transferred to the recipient in perpetuity or for a
// fixed term (regardless of how the transaction is characterized), the
// Corresponding Source conveyed under this section must be accompanied
// by the Installation Information.  But this requirement does not apply
// if neither you nor any third party retains the ability to install
// modified object code on the User Product (for example, the work has
// been installed in ROM).
// 
//   The requirement to provide Installation Information does not include a
// requirement to continue to provide support service, warranty, or updates
// for a work that has been modified or installed by the recipient, or for
// the User Product in which it has been modified or installed.  Access to a
// network may be denied when the modification itself materially and
// adversely affects the operation of the network or violates the rules and
// protocols for communication across the network.
// 
//   Corresponding Source conveyed, and Installation Information provided,
// in accord with this section must be in a format that is publicly
// documented (and with an implementation available to the public in
// source code form), and must require no special password or key for
// unpacking, reading or copying.
// 
//   7. Additional Terms.
// 
//   "Additional permissions" are terms that supplement the terms of this
// License by making exceptions from one or more of its conditions.
// Additional permissions that are applicable to the entire Program shall
// be treated as though they were included in this License, to the extent
// that they are valid under applicable law.  If additional permissions
// apply only to part of the Program, that part may be used separately
// under those permissions, but the entire Program remains governed by
// this License without regard to the additional permissions.
// 
//   When you convey a copy of a covered work, you may at your option
// remove any additional permissions from that copy, or from any part of
// it.  (Additional permissions may be written to require their own
// removal in certain cases when you modify the work.)  You may place
// additional permissions on material, added by you to a covered work,
// for which you have or can give appropriate copyright permission.
// 
//   Notwithstanding any other provision of this License, for material you
// add to a covered work, you may (if authorized by the copyright holders of
// that material) supplement the terms of this License with terms:
// 
//     a) Disclaiming warranty or limiting liability differently from the
//     terms of sections 15 and 16 of this License; or
// 
//     b) Requiring preservation of specified reasonable legal notices or
//     author attributions in that material or in the Appropriate Legal
//     Notices displayed by works containing it; or
// 
//     c) Prohibiting misrepresentation of the origin of that material, or
//     requiring that modified versions of such material be marked in
//     reasonable ways as different from the original version; or
// 
//     d) Limiting the use for publicity purposes of names of licensors or
//     authors of the material; or
// 
//     e) Declining to grant rights under trademark law for use of some
//     trade names, trademarks, or service marks; or
// 
//     f) Requiring indemnification of licensors and authors of that
//     material by anyone who conveys the material (or modified versions of
//     it) with contractual assumptions of liability to the recipient, for
//     any liability that these contractual assumptions directly impose on
//     those licensors and authors.
// 
//   All other non-permissive additional terms are considered "further
// restrictions" within the meaning of section 10.  If the Program as you
// received it, or any part of it, contains a notice stating that it is
// governed by this License along with a term that is a further
// restriction, you may remove that term.  If a license document contains
// a further restriction but permits relicensing or conveying under this
// License, you may add to a covered work material governed by the terms
// of that license document, provided that the further restriction does
// not survive such relicensing or conveying.
// 
//   If you add terms to a covered work in accord with this section, you
// must place, in the relevant source files, a statement of the
// additional terms that apply to those files, or a notice indicating
// where to find the applicable terms.
// 
//   Additional terms, permissive or non-permissive, may be stated in the
// form of a separately written license, or stated as exceptions;
// the above requirements apply either way.
// 
//   8. Termination.
// 
//   You may not propagate or modify a covered work except as expressly
// provided under this License.  Any attempt otherwise to propagate or
// modify it is void, and will automatically terminate your rights under
// this License (including any patent licenses granted under the third
// paragraph of section 11).
// 
//   However, if you cease all violation of this License, then your
// license from a particular copyright holder is reinstated (a)
// provisionally, unless and until the copyright holder explicitly and
// finally terminates your license, and (b) permanently, if the copyright
// holder fails to notify you of the violation by some reasonable means
// prior to 60 days after the cessation.
// 
//   Moreover, your license from a particular copyright holder is
// reinstated permanently if the copyright holder notifies you of the
// violation by some reasonable means, this is the first time you have
// received notice of violation of this License (for any work) from that
// copyright holder, and you cure the violation prior to 30 days after
// your receipt of the notice.
// 
//   Termination of your rights under this section does not terminate the
// licenses of parties who have received copies or rights from you under
// this License.  If your rights have been terminated and not permanently
// reinstated, you do not qualify to receive new licenses for the same
// material under section 10.
// 
//   9. Acceptance Not Required for Having Copies.
// 
//   You are not required to accept this License in order to receive or
// run a copy of the Program.  Ancillary propagation of a covered work
// occurring solely as a consequence of using peer-to-peer transmission
// to receive a copy likewise does not require acceptance.  However,
// nothing other than this License grants you permission to propagate or
// modify any covered work.  These actions infringe copyright if you do
// not accept this License.  Therefore, by modifying or propagating a
// covered work, you indicate your acceptance of this License to do so.
// 
//   10. Automatic Licensing of Downstream Recipients.
// 
//   Each time you convey a covered work, the recipient automatically
// receives a license from the original licensors, to run, modify and
// propagate that work, subject to this License.  You are not responsible
// for enforcing compliance by third parties with this License.
// 
//   An "entity transaction" is a transaction transferring control of an
// organization, or substantially all assets of one, or subdividing an
// organization, or merging organizations.  If propagation of a covered
// work results from an entity transaction, each party to that
// transaction who receives a copy of the work also receives whatever
// licenses to the work the party's predecessor in interest had or could
// give under the previous paragraph, plus a right to possession of the
// Corresponding Source of the work from the predecessor in interest, if
// the predecessor has it or can get it with reasonable efforts.
// 
//   You may not impose any further restrictions on the exercise of the
// rights granted or affirmed under this License.  For example, you may
// not impose a license fee, royalty, or other charge for exercise of
// rights granted under this License, and you may not initiate litigation
// (including a cross-claim or counterclaim in a lawsuit) alleging that
// any patent claim is infringed by making, using, selling, offering for
// sale, or importing the Program or any portion of it.
// 
//   11. Patents.
// 
//   A "contributor" is a copyright holder who authorizes use under this
// License of the Program or a work on which the Program is based.  The
// work thus licensed is called the contributor's "contributor version".
// 
//   A contributor's "essential patent claims" are all patent claims
// owned or controlled by the contributor, whether already acquired or
// hereafter acquired, that would be infringed by some manner, permitted
// by this License, of making, using, or selling its contributor version,
// but do not include claims that would be infringed only as a
// consequence of further modification of the contributor version.  For
// purposes of this definition, "control" includes the right to grant
// patent sublicenses in a manner consistent with the requirements of
// this License.
// 
//   Each contributor grants you a non-exclusive, worldwide, royalty-free
// patent license under the contributor's essential patent claims, to
// make, use, sell, offer for sale, import and otherwise run, modify and
// propagate the contents of its contributor version.
// 
//   In the following three paragraphs, a "patent license" is any express
// agreement or commitment, however denominated, not to enforce a patent
// (such as an express permission to practice a patent or covenant not to
// sue for patent infringement).  To "grant" such a patent license to a
// party means to make such an agreement or commitment not to enforce a
// patent against the party.
// 
//   If you convey a covered work, knowingly relying on a patent license,
// and the Corresponding Source of the work is not available for anyone
// to copy, free of charge and under the terms of this License, through a
// publicly available network server or other readily accessible means,
// then you must either (1) cause the Corresponding Source to be so
// available, or (2) arrange to deprive yourself of the benefit of the
// patent license for this particular work, or (3) arrange, in a manner
// consistent with the requirements of this License, to extend the patent
// license to downstream recipients.  "Knowingly relying" means you have
// actual knowledge that, but for the patent license, your conveying the
// covered work in a country, or your recipient's use of the covered work
// in a country, would infringe one or more identifiable patents in that
// country that you have reason to believe are valid.
// 
//   If, pursuant to or in connection with a single transaction or
// arrangement, you convey, or propagate by procuring conveyance of, a
// covered work, and grant a patent license to some of the parties
// receiving the covered work authorizing them to use, propagate, modify
// or convey a specific copy of the covered work, then the patent license
// you grant is automatically extended to all recipients of the covered
// work and works based on it.
// 
//   A patent license is "discriminatory" if it does not include within
// the scope of its coverage, prohibits the exercise of, or is
// conditioned on the non-exercise of one or more of the rights that are
// specifically granted under this License.  You may not convey a covered
// work if you are a party to an arrangement with a third party that is
// in the business of distributing software, under which you make payment
// to the third party based on the extent of your activity of conveying
// the work, and under which the third party grants, to any of the
// parties who would receive the covered work from you, a discriminatory
// patent license (a) in connection with copies of the covered work
// conveyed by you (or copies made from those copies), or (b) primarily
// for and in connection with specific products or compilations that
// contain the covered work, unless you entered into that arrangement,
// or that patent license was granted, prior to 28 March 2007.
// 
//   Nothing in this License shall be construed as excluding or limiting
// any implied license or other defenses to infringement that may
// otherwise be available to you under applicable patent law.
// 
//   12. No Surrender of Others' Freedom.
// 
//   If 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 convey a
// covered work so as to satisfy simultaneously your obligations under this
// License and any other pertinent obligations, then as a consequence you may
// not convey it at all.  For example, if you agree to terms that obligate you
// to collect a royalty for further conveying from those to whom you convey
// the Program, the only way you could satisfy both those terms and this
// License would be to refrain entirely from conveying the Program.
// 
//   13. Use with the GNU Affero General Public License.
// 
//   Notwithstanding any other provision of this License, you have
// permission to link or combine any covered work with a work licensed
// under version 3 of the GNU Affero General Public License into a single
// combined work, and to convey the resulting work.  The terms of this
// License will continue to apply to the part which is the covered work,
// but the special requirements of the GNU Affero General Public License,
// section 13, concerning interaction through a network will apply to the
// combination as such.
// 
//   14. Revised Versions of this License.
// 
//   The Free Software Foundation may publish revised and/or new versions of
// the GNU 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 that a certain numbered version of the GNU General
// Public License "or any later version" applies to it, you have the
// option of following the terms and conditions either of that numbered
// version or of any later version published by the Free Software
// Foundation.  If the Program does not specify a version number of the
// GNU General Public License, you may choose any version ever published
// by the Free Software Foundation.
// 
//   If the Program specifies that a proxy can decide which future
// versions of the GNU General Public License can be used, that proxy's
// public statement of acceptance of a version permanently authorizes you
// to choose that version for the Program.
// 
//   Later license versions may give you additional or different
// permissions.  However, no additional obligations are imposed on any
// author or copyright holder as a result of your choosing to follow a
// later version.
// 
//   15. Disclaimer of Warranty.
// 
//   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.
// 
//   16. Limitation of Liability.
// 
//   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
// WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
// 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.
// 
//   17. Interpretation of Sections 15 and 16.
// 
//   If the disclaimer of warranty and limitation of liability provided
// above cannot be given local legal effect according to their terms,
// reviewing courts shall apply local law that most closely approximates
// an absolute waiver of all civil liability in connection with the
// Program, unless a warranty or assumption of liability accompanies a
// copy of the Program in return for a fee.
// 
//                      END OF TERMS AND CONDITIONS

\n \
                    GNU GENERAL PUBLIC LICENSE\n \
                       Version 3, 29 June 2007\n \
\n \
 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>\n \
 Everyone is permitted to copy and distribute verbatim copies\n \
 of this license document, but changing it is not allowed.\n \
\n \
                            Preamble\n \
\n \
  The GNU General Public License is a free, copyleft license for\n \
software and other kinds of works.\n \
\n \
  The licenses for most software and other practical works are designed\n \
to take away your freedom to share and change the works.  By contrast,\n \
the GNU General Public License is intended to guarantee your freedom to\n \
share and change all versions of a program--to make sure it remains free\n \
software for all its users.  We, the Free Software Foundation, use the\n \
GNU General Public License for most of our software; it applies also to\n \
any other work released this way by its authors.  You can apply it to\n \
your programs, too.\n \
\n \
  When we speak of free software, we are referring to freedom, not\n \
price.  Our General Public Licenses are designed to make sure that you\n \
have the freedom to distribute copies of free software (and charge for\n \
them if you wish), that you receive source code or can get it if you\n \
want it, that you can change the software or use pieces of it in new\n \
free programs, and that you know you can do these things.\n \
\n \
  To protect your rights, we need to prevent others from denying you\n \
these rights or asking you to surrender the rights.  Therefore, you have\n \
certain responsibilities if you distribute copies of the software, or if\n \
you modify it: responsibilities to respect the freedom of others.\n \
\n \
  For example, if you distribute copies of such a program, whether\n \
gratis or for a fee, you must pass on to the recipients the same\n \
freedoms that you received.  You must make sure that they, too, receive\n \
or can get the source code.  And you must show them these terms so they\n \
know their rights.\n \
\n \
  Developers that use the GNU GPL protect your rights with two steps:\n \
(1) assert copyright on the software, and (2) offer you this License\n \
giving you legal permission to copy, distribute and/or modify it.\n \
\n \
  For the developers' and authors' protection, the GPL clearly explains\n \
that there is no warranty for this free software.  For both users' and\n \
authors' sake, the GPL requires that modified versions be marked as\n \
changed, so that their problems will not be attributed erroneously to\n \
authors of previous versions.\n \
\n \
  Some devices are designed to deny users access to install or run\n \
modified versions of the software inside them, although the manufacturer\n \
can do so.  This is fundamentally incompatible with the aim of\n \
protecting users' freedom to change the software.  The systematic\n \
pattern of such abuse occurs in the area of products for individuals to\n \
use, which is precisely where it is most unacceptable.  Therefore, we\n \
have designed this version of the GPL to prohibit the practice for those\n \
products.  If such problems arise substantially in other domains, we\n \
stand ready to extend this provision to those domains in future versions\n \
of the GPL, as needed to protect the freedom of users.\n \
\n \
  Finally, every program is threatened constantly by software patents.\n \
States should not allow patents to restrict development and use of\n \
software on general-purpose computers, but in those that do, we wish to\n \
avoid the special danger that patents applied to a free program could\n \
make it effectively proprietary.  To prevent this, the GPL assures that\n \
patents cannot be used to render the program non-free.\n \
\n \
  The precise terms and conditions for copying, distribution and\n \
modification follow.\n \
\n \
                       TERMS AND CONDITIONS\n \
\n \
  0. Definitions.\n \
\n \
  \"This License\" refers to version 3 of the GNU General Public License.\n \
\n \
  \"Copyright\" also means copyright-like laws that apply to other kinds of\n \
works, such as semiconductor masks.\n \
\n \
  \"The Program\" refers to any copyrightable work licensed under this\n \
License.  Each licensee is addressed as \"you\".  \"Licensees\" and\n \
\"recipients\" may be individuals or organizations.\n \
\n \
  To \"modify\" a work means to copy from or adapt all or part of the work\n \
in a fashion requiring copyright permission, other than the making of an\n \
exact copy.  The resulting work is called a \"modified version\" of the\n \
earlier work or a work \"based on\" the earlier work.\n \
\n \
  A \"covered work\" means either the unmodified Program or a work based\n \
on the Program.\n \
\n \
  To \"propagate\" a work means to do anything with it that, without\n \
permission, would make you directly or secondarily liable for\n \
infringement under applicable copyright law, except executing it on a\n \
computer or modifying a private copy.  Propagation includes copying,\n \
distribution (with or without modification), making available to the\n \
public, and in some countries other activities as well.\n \
\n \
  To \"convey\" a work means any kind of propagation that enables other\n \
parties to make or receive copies.  Mere interaction with a user through\n \
a computer network, with no transfer of a copy, is not conveying.\n \
\n \
  An interactive user interface displays \"Appropriate Legal Notices\"\n \
to the extent that it includes a convenient and prominently visible\n \
feature that (1) displays an appropriate copyright notice, and (2)\n \
tells the user that there is no warranty for the work (except to the\n \
extent that warranties are provided), that licensees may convey the\n \
work under this License, and how to view a copy of this License.  If\n \
the interface presents a list of user commands or options, such as a\n \
menu, a prominent item in the list meets this criterion.\n \
\n \
  1. Source Code.\n \
\n \
  The \"source code\" for a work means the preferred form of the work\n \
for making modifications to it.  \"Object code\" means any non-source\n \
form of a work.\n \
\n \
  A \"Standard Interface\" means an interface that either is an official\n \
standard defined by a recognized standards body, or, in the case of\n \
interfaces specified for a particular programming language, one that\n \
is widely used among developers working in that language.\n \
\n \
  The \"System Libraries\" of an executable work include anything, other\n \
than the work as a whole, that (a) is included in the normal form of\n \
packaging a Major Component, but which is not part of that Major\n \
Component, and (b) serves only to enable use of the work with that\n \
Major Component, or to implement a Standard Interface for which an\n \
implementation is available to the public in source code form.  A\n \
\"Major Component\", in this context, means a major essential component\n \
(kernel, window system, and so on) of the specific operating system\n \
(if any) on which the executable work runs, or a compiler used to\n \
produce the work, or an object code interpreter used to run it.\n \
\n \
  The \"Corresponding Source\" for a work in object code form means all\n \
the source code needed to generate, install, and (for an executable\n \
work) run the object code and to modify the work, including scripts to\n \
control those activities.  However, it does not include the work's\n \
System Libraries, or general-purpose tools or generally available free\n \
programs which are used unmodified in performing those activities but\n \
which are not part of the work.  For example, Corresponding Source\n \
includes interface definition files associated with source files for\n \
the work, and the source code for shared libraries and dynamically\n \
linked subprograms that the work is specifically designed to require,\n \
such as by intimate data communication or control flow between those\n \
subprograms and other parts of the work.\n \
\n \
  The Corresponding Source need not include anything that users\n \
can regenerate automatically from other parts of the Corresponding\n \
Source.\n \
\n \
  The Corresponding Source for a work in source code form is that\n \
same work.\n \
\n \
  2. Basic Permissions.\n \
\n \
  All rights granted under this License are granted for the term of\n \
copyright on the Program, and are irrevocable provided the stated\n \
conditions are met.  This License explicitly affirms your unlimited\n \
permission to run the unmodified Program.  The output from running a\n \
covered work is covered by this License only if the output, given its\n \
content, constitutes a covered work.  This License acknowledges your\n \
rights of fair use or other equivalent, as provided by copyright law.\n \
\n \
  You may make, run and propagate covered works that you do not\n \
convey, without conditions so long as your license otherwise remains\n \
in force.  You may convey covered works to others for the sole purpose\n \
of having them make modifications exclusively for you, or provide you\n \
with facilities for running those works, provided that you comply with\n \
the terms of this License in conveying all material for which you do\n \
not control copyright.  Those thus making or running the covered works\n \
for you must do so exclusively on your behalf, under your direction\n \
and control, on terms that prohibit them from making any copies of\n \
your copyrighted material outside their relationship with you.\n \
\n \
  Conveying under any other circumstances is permitted solely under\n \
the conditions stated below.  Sublicensing is not allowed; section 10\n \
makes it unnecessary.\n \
\n \
  3. Protecting Users' Legal Rights From Anti-Circumvention Law.\n \
\n \
  No covered work shall be deemed part of an effective technological\n \
measure under any applicable law fulfilling obligations under article\n \
11 of the WIPO copyright treaty adopted on 20 December 1996, or\n \
similar laws prohibiting or restricting circumvention of such\n \
measures.\n \
\n \
  When you convey a covered work, you waive any legal power to forbid\n \
circumvention of technological measures to the extent such circumvention\n \
is effected by exercising rights under this License with respect to\n \
the covered work, and you disclaim any intention to limit operation or\n \
modification of the work as a means of enforcing, against the work's\n \
users, your or third parties' legal rights to forbid circumvention of\n \
technological measures.\n \
\n \
  4. Conveying Verbatim Copies.\n \
\n \
  You may convey verbatim copies of the Program's source code as you\n \
receive it, in any medium, provided that you conspicuously and\n \
appropriately publish on each copy an appropriate copyright notice;\n \
keep intact all notices stating that this License and any\n \
non-permissive terms added in accord with section 7 apply to the code;\n \
keep intact all notices of the absence of any warranty; and give all\n \
recipients a copy of this License along with the Program.\n \
\n \
  You may charge any price or no price for each copy that you convey,\n \
and you may offer support or warranty protection for a fee.\n \
\n \
  5. Conveying Modified Source Versions.\n \
\n \
  You may convey a work based on the Program, or the modifications to\n \
produce it from the Program, in the form of source code under the\n \
terms of section 4, provided that you also meet all of these conditions:\n \
\n \
    a) The work must carry prominent notices stating that you modified\n \
    it, and giving a relevant date.\n \
\n \
    b) The work must carry prominent notices stating that it is\n \
    released under this License and any conditions added under section\n \
    7.  This requirement modifies the requirement in section 4 to\n \
    \"keep intact all notices\".\n \
\n \
    c) You must license the entire work, as a whole, under this\n \
    License to anyone who comes into possession of a copy.  This\n \
    License will therefore apply, along with any applicable section 7\n \
    additional terms, to the whole of the work, and all its parts,\n \
    regardless of how they are packaged.  This License gives no\n \
    permission to license the work in any other way, but it does not\n \
    invalidate such permission if you have separately received it.\n \
\n \
    d) If the work has interactive user interfaces, each must display\n \
    Appropriate Legal Notices; however, if the Program has interactive\n \
    interfaces that do not display Appropriate Legal Notices, your\n \
    work need not make them do so.\n \
\n \
  A compilation of a covered work with other separate and independent\n \
works, which are not by their nature extensions of the covered work,\n \
and which are not combined with it such as to form a larger program,\n \
in or on a volume of a storage or distribution medium, is called an\n \
\"aggregate\" if the compilation and its resulting copyright are not\n \
used to limit the access or legal rights of the compilation's users\n \
beyond what the individual works permit.  Inclusion of a covered work\n \
in an aggregate does not cause this License to apply to the other\n \
parts of the aggregate.\n \
\n \
  6. Conveying Non-Source Forms.\n \
\n \
  You may convey a covered work in object code form under the terms\n \
of sections 4 and 5, provided that you also convey the\n \
machine-readable Corresponding Source under the terms of this License,\n \
in one of these ways:\n \
\n \
    a) Convey the object code in, or embodied in, a physical product\n \
    (including a physical distribution medium), accompanied by the\n \
    Corresponding Source fixed on a durable physical medium\n \
    customarily used for software interchange.\n \
\n \
    b) Convey the object code in, or embodied in, a physical product\n \
    (including a physical distribution medium), accompanied by a\n \
    written offer, valid for at least three years and valid for as\n \
    long as you offer spare parts or customer support for that product\n \
    model, to give anyone who possesses the object code either (1) a\n \
    copy of the Corresponding Source for all the software in the\n \
    product that is covered by this License, on a durable physical\n \
    medium customarily used for software interchange, for a price no\n \
    more than your reasonable cost of physically performing this\n \
    conveying of source, or (2) access to copy the\n \
    Corresponding Source from a network server at no charge.\n \
\n \
    c) Convey individual copies of the object code with a copy of the\n \
    written offer to provide the Corresponding Source.  This\n \
    alternative is allowed only occasionally and noncommercially, and\n \
    only if you received the object code with such an offer, in accord\n \
    with subsection 6b.\n \
\n \
    d) Convey the object code by offering access from a designated\n \
    place (gratis or for a charge), and offer equivalent access to the\n \
    Corresponding Source in the same way through the same place at no\n \
    further charge.  You need not require recipients to copy the\n \
    Corresponding Source along with the object code.  If the place to\n \
    copy the object code is a network server, the Corresponding Source\n \
    may be on a different server (operated by you or a third party)\n \
    that supports equivalent copying facilities, provided you maintain\n \
    clear directions next to the object code saying where to find the\n \
    Corresponding Source.  Regardless of what server hosts the\n \
    Corresponding Source, you remain obligated to ensure that it is\n \
    available for as long as needed to satisfy these requirements.\n \
\n \
    e) Convey the object code using peer-to-peer transmission, provided\n \
    you inform other peers where the object code and Corresponding\n \
    Source of the work are being offered to the general public at no\n \
    charge under subsection 6d.\n \
\n \
  A separable portion of the object code, whose source code is excluded\n \
from the Corresponding Source as a System Library, need not be\n \
included in conveying the object code work.\n \
\n \
  A \"User Product\" is either (1) a \"consumer product\", which means any\n \
tangible personal property which is normally used for personal, family,\n \
or household purposes, or (2) anything designed or sold for incorporation\n \
into a dwelling.  In determining whether a product is a consumer product,\n \
doubtful cases shall be resolved in favor of coverage.  For a particular\n \
product received by a particular user, \"normally used\" refers to a\n \
typical or common use of that class of product, regardless of the status\n \
of the particular user or of the way in which the particular user\n \
actually uses, or expects or is expected to use, the product.  A product\n \
is a consumer product regardless of whether the product has substantial\n \
commercial, industrial or non-consumer uses, unless such uses represent\n \
the only significant mode of use of the product.\n \
\n \
  \"Installation Information\" for a User Product means any methods,\n \
procedures, authorization keys, or other information required to install\n \
and execute modified versions of a covered work in that User Product from\n \
a modified version of its Corresponding Source.  The information must\n \
suffice to ensure that the continued functioning of the modified object\n \
code is in no case prevented or interfered with solely because\n \
modification has been made.\n \
\n \
  If you convey an object code work under this section in, or with, or\n \
specifically for use in, a User Product, and the conveying occurs as\n \
part of a transaction in which the right of possession and use of the\n \
User Product is transferred to the recipient in perpetuity or for a\n \
fixed term (regardless of how the transaction is characterized), the\n \
Corresponding Source conveyed under this section must be accompanied\n \
by the Installation Information.  But this requirement does not apply\n \
if neither you nor any third party retains the ability to install\n \
modified object code on the User Product (for example, the work has\n \
been installed in ROM).\n \
\n \
  The requirement to provide Installation Information does not include a\n \
requirement to continue to provide support service, warranty, or updates\n \
for a work that has been modified or installed by the recipient, or for\n \
the User Product in which it has been modified or installed.  Access to a\n \
network may be denied when the modification itself materially and\n \
adversely affects the operation of the network or violates the rules and\n \
protocols for communication across the network.\n \
\n \
  Corresponding Source conveyed, and Installation Information provided,\n \
in accord with this section must be in a format that is publicly\n \
documented (and with an implementation available to the public in\n \
source code form), and must require no special password or key for\n \
unpacking, reading or copying.\n \
\n \
  7. Additional Terms.\n \
\n \
  \"Additional permissions\" are terms that supplement the terms of this\n \
License by making exceptions from one or more of its conditions.\n \
Additional permissions that are applicable to the entire Program shall\n \
be treated as though they were included in this License, to the extent\n \
that they are valid under applicable law.  If additional permissions\n \
apply only to part of the Program, that part may be used separately\n \
under those permissions, but the entire Program remains governed by\n \
this License without regard to the additional permissions.\n \
\n \
  When you convey a copy of a covered work, you may at your option\n \
remove any additional permissions from that copy, or from any part of\n \
it.  (Additional permissions may be written to require their own\n \
removal in certain cases when you modify the work.)  You may place\n \
additional permissions on material, added by you to a covered work,\n \
for which you have or can give appropriate copyright permission.\n \
\n \
  Notwithstanding any other provision of this License, for material you\n \
add to a covered work, you may (if authorized by the copyright holders of\n \
that material) supplement the terms of this License with terms:\n \
\n \
    a) Disclaiming warranty or limiting liability differently from the\n \
    terms of sections 15 and 16 of this License; or\n \
\n \
    b) Requiring preservation of specified reasonable legal notices or\n \
    author attributions in that material or in the Appropriate Legal\n \
    Notices displayed by works containing it; or\n \
\n \
    c) Prohibiting misrepresentation of the origin of that material, or\n \
    requiring that modified versions of such material be marked in\n \
    reasonable ways as different from the original version; or\n \
\n \
    d) Limiting the use for publicity purposes of names of licensors or\n \
    authors of the material; or\n \
\n \
    e) Declining to grant rights under trademark law for use of some\n \
    trade names, trademarks, or service marks; or\n \
\n \
    f) Requiring indemnification of licensors and authors of that\n \
    material by anyone who conveys the material (or modified versions of\n \
    it) with contractual assumptions of liability to the recipient, for\n \
    any liability that these contractual assumptions directly impose on\n \
    those licensors and authors.\n \
\n \
  All other non-permissive additional terms are considered \"further\n \
restrictions\" within the meaning of section 10.  If the Program as you\n \
received it, or any part of it, contains a notice stating that it is\n \
governed by this License along with a term that is a further\n \
restriction, you may remove that term.  If a license document contains\n \
a further restriction but permits relicensing or conveying under this\n \
License, you may add to a covered work material governed by the terms\n \
of that license document, provided that the further restriction does\n \
not survive such relicensing or conveying.\n \
\n \
  If you add terms to a covered work in accord with this section, you\n \
must place, in the relevant source files, a statement of the\n \
additional terms that apply to those files, or a notice indicating\n \
where to find the applicable terms.\n \
\n \
  Additional terms, permissive or non-permissive, may be stated in the\n \
form of a separately written license, or stated as exceptions;\n \
the above requirements apply either way.\n \
\n \
  8. Termination.\n \
\n \
  You may not propagate or modify a covered work except as expressly\n \
provided under this License.  Any attempt otherwise to propagate or\n \
modify it is void, and will automatically terminate your rights under\n \
this License (including any patent licenses granted under the third\n \
paragraph of section 11).\n \
\n \
  However, if you cease all violation of this License, then your\n \
license from a particular copyright holder is reinstated (a)\n \
provisionally, unless and until the copyright holder explicitly and\n \
finally terminates your license, and (b) permanently, if the copyright\n \
holder fails to notify you of the violation by some reasonable means\n \
prior to 60 days after the cessation.\n \
\n \
  Moreover, your license from a particular copyright holder is\n \
reinstated permanently if the copyright holder notifies you of the\n \
violation by some reasonable means, this is the first time you have\n \
received notice of violation of this License (for any work) from that\n \
copyright holder, and you cure the violation prior to 30 days after\n \
your receipt of the notice.\n \
\n \
  Termination of your rights under this section does not terminate the\n \
licenses of parties who have received copies or rights from you under\n \
this License.  If your rights have been terminated and not permanently\n \
reinstated, you do not qualify to receive new licenses for the same\n \
material under section 10.\n \
\n \
  9. Acceptance Not Required for Having Copies.\n \
\n \
  You are not required to accept this License in order to receive or\n \
run a copy of the Program.  Ancillary propagation of a covered work\n \
occurring solely as a consequence of using peer-to-peer transmission\n \
to receive a copy likewise does not require acceptance.  However,\n \
nothing other than this License grants you permission to propagate or\n \
modify any covered work.  These actions infringe copyright if you do\n \
not accept this License.  Therefore, by modifying or propagating a\n \
covered work, you indicate your acceptance of this License to do so.\n \
\n \
  10. Automatic Licensing of Downstream Recipients.\n \
\n \
  Each time you convey a covered work, the recipient automatically\n \
receives a license from the original licensors, to run, modify and\n \
propagate that work, subject to this License.  You are not responsible\n \
for enforcing compliance by third parties with this License.\n \
\n \
  An \"entity transaction\" is a transaction transferring control of an\n \
organization, or substantially all assets of one, or subdividing an\n \
organization, or merging organizations.  If propagation of a covered\n \
work results from an entity transaction, each party to that\n \
transaction who receives a copy of the work also receives whatever\n \
licenses to the work the party's predecessor in interest had or could\n \
give under the previous paragraph, plus a right to possession of the\n \
Corresponding Source of the work from the predecessor in interest, if\n \
the predecessor has it or can get it with reasonable efforts.\n \
\n \
  You may not impose any further restrictions on the exercise of the\n \
rights granted or affirmed under this License.  For example, you may\n \
not impose a license fee, royalty, or other charge for exercise of\n \
rights granted under this License, and you may not initiate litigation\n \
(including a cross-claim or counterclaim in a lawsuit) alleging that\n \
any patent claim is infringed by making, using, selling, offering for\n \
sale, or importing the Program or any portion of it.\n \
\n \
  11. Patents.\n \
\n \
  A \"contributor\" is a copyright holder who authorizes use under this\n \
License of the Program or a work on which the Program is based.  The\n \
work thus licensed is called the contributor's \"contributor version\".\n \
\n \
  A contributor's \"essential patent claims\" are all patent claims\n \
owned or controlled by the contributor, whether already acquired or\n \
hereafter acquired, that would be infringed by some manner, permitted\n \
by this License, of making, using, or selling its contributor version,\n \
but do not include claims that would be infringed only as a\n \
consequence of further modification of the contributor version.  For\n \
purposes of this definition, \"control\" includes the right to grant\n \
patent sublicenses in a manner consistent with the requirements of\n \
this License.\n \
\n \
  Each contributor grants you a non-exclusive, worldwide, royalty-free\n \
patent license under the contributor's essential patent claims, to\n \
make, use, sell, offer for sale, import and otherwise run, modify and\n \
propagate the contents of its contributor version.\n \
\n \
  In the following three paragraphs, a \"patent license\" is any express\n \
agreement or commitment, however denominated, not to enforce a patent\n \
(such as an express permission to practice a patent or covenant not to\n \
sue for patent infringement).  To \"grant\" such a patent license to a\n \
party means to make such an agreement or commitment not to enforce a\n \
patent against the party.\n \
\n \
  If you convey a covered work, knowingly relying on a patent license,\n \
and the Corresponding Source of the work is not available for anyone\n \
to copy, free of charge and under the terms of this License, through a\n \
publicly available network server or other readily accessible means,\n \
then you must either (1) cause the Corresponding Source to be so\n \
available, or (2) arrange to deprive yourself of the benefit of the\n \
patent license for this particular work, or (3) arrange, in a manner\n \
consistent with the requirements of this License, to extend the patent\n \
license to downstream recipients.  \"Knowingly relying\" means you have\n \
actual knowledge that, but for the patent license, your conveying the\n \
covered work in a country, or your recipient's use of the covered work\n \
in a country, would infringe one or more identifiable patents in that\n \
country that you have reason to believe are valid.\n \
\n \
  If, pursuant to or in connection with a single transaction or\n \
arrangement, you convey, or propagate by procuring conveyance of, a\n \
covered work, and grant a patent license to some of the parties\n \
receiving the covered work authorizing them to use, propagate, modify\n \
or convey a specific copy of the covered work, then the patent license\n \
you grant is automatically extended to all recipients of the covered\n \
work and works based on it.\n \
\n \
  A patent license is \"discriminatory\" if it does not include within\n \
the scope of its coverage, prohibits the exercise of, or is\n \
conditioned on the non-exercise of one or more of the rights that are\n \
specifically granted under this License.  You may not convey a covered\n \
work if you are a party to an arrangement with a third party that is\n \
in the business of distributing software, under which you make payment\n \
to the third party based on the extent of your activity of conveying\n \
the work, and under which the third party grants, to any of the\n \
parties who would receive the covered work from you, a discriminatory\n \
patent license (a) in connection with copies of the covered work\n \
conveyed by you (or copies made from those copies), or (b) primarily\n \
for and in connection with specific products or compilations that\n \
contain the covered work, unless you entered into that arrangement,\n \
or that patent license was granted, prior to 28 March 2007.\n \
\n \
  Nothing in this License shall be construed as excluding or limiting\n \
any implied license or other defenses to infringement that may\n \
otherwise be available to you under applicable patent law.\n \
\n \
  12. No Surrender of Others' Freedom.\n \
\n \
  If conditions are imposed on you (whether by court order, agreement or\n \
otherwise) that contradict the conditions of this License, they do not\n \
excuse you from the conditions of this License.  If you cannot convey a\n \
covered work so as to satisfy simultaneously your obligations under this\n \
License and any other pertinent obligations, then as a consequence you may\n \
not convey it at all.  For example, if you agree to terms that obligate you\n \
to collect a royalty for further conveying from those to whom you convey\n \
the Program, the only way you could satisfy both those terms and this\n \
License would be to refrain entirely from conveying the Program.\n \
\n \
  13. Use with the GNU Affero General Public License.\n \
\n \
  Notwithstanding any other provision of this License, you have\n \
permission to link or combine any covered work with a work licensed\n \
under version 3 of the GNU Affero General Public License into a single\n \
combined work, and to convey the resulting work.  The terms of this\n \
License will continue to apply to the part which is the covered work,\n \
but the special requirements of the GNU Affero General Public License,\n \
section 13, concerning interaction through a network will apply to the\n \
combination as such.\n \
\n \
  14. Revised Versions of this License.\n \
\n \
  The Free Software Foundation may publish revised and/or new versions of\n \
the GNU General Public License from time to time.  Such new versions will\n \
be similar in spirit to the present version, but may differ in detail to\n \
address new problems or concerns.\n \
\n \
  Each version is given a distinguishing version number.  If the\n \
Program specifies that a certain numbered version of the GNU General\n \
Public License \"or any later version\" applies to it, you have the\n \
option of following the terms and conditions either of that numbered\n \
version or of any later version published by the Free Software\n \
Foundation.  If the Program does not specify a version number of the\n \
GNU General Public License, you may choose any version ever published\n \
by the Free Software Foundation.\n \
\n \
  If the Program specifies that a proxy can decide which future\n \
versions of the GNU General Public License can be used, that proxy's\n \
public statement of acceptance of a version permanently authorizes you\n \
to choose that version for the Program.\n \
\n \
  Later license versions may give you additional or different\n \
permissions.  However, no additional obligations are imposed on any\n \
author or copyright holder as a result of your choosing to follow a\n \
later version.\n \
\n \
  15. Disclaimer of Warranty.\n \
\n \
  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY\n \
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT\n \
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM \"AS IS\" WITHOUT WARRANTY\n \
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,\n \
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR\n \
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM\n \
IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF\n \
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.\n \
\n \
  16. Limitation of Liability.\n \
\n \
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\n \
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS\n \
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY\n \
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE\n \
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF\n \
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD\n \
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),\n \
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF\n \
SUCH DAMAGES.\n \
\n \
  17. Interpretation of Sections 15 and 16.\n \
\n \
  If the disclaimer of warranty and limitation of liability provided\n \
above cannot be given local legal effect according to their terms,\n \
reviewing courts shall apply local law that most closely approximates\n \
an absolute waiver of all civil liability in connection with the\n \
Program, unless a warranty or assumption of liability accompanies a\n \
copy of the Program in return for a fee.\n \
\n \
                     END OF TERMS AND CONDITIONS\n \
