+GCC RUNTIME LIBRARY EXCEPTION
+
+Version 3.1, 31 March 2009
+
+Copyright (C) 2009 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.
+
+This GCC Runtime Library Exception ("Exception") is an additional
+permission under section 7 of the GNU General Public License, version
+3 ("GPLv3"). It applies to a given file (the "Runtime Library") that
+bears a notice placed by the copyright holder of the file stating that
+the file is governed by GPLv3 along with this Exception.
+
+When you use GCC to compile a program, GCC may combine portions of
+certain GCC header files and runtime libraries with the compiled
+program. The purpose of this Exception is to allow compilation of
+non-GPL (including proprietary) programs to use, in this way, the
+header files and runtime libraries covered by this Exception.
+
+0. Definitions.
+
+A file is an "Independent Module" if it either requires the Runtime
+Library for execution after a Compilation Process, or makes use of an
+interface provided by the Runtime Library, but is not otherwise based
+on the Runtime Library.
+
+"GCC" means a version of the GNU Compiler Collection, with or without
+modifications, governed by version 3 (or a specified later version) of
+the GNU General Public License (GPL) with the option of using any
+subsequent versions published by the FSF.
+
+"GPL-compatible Software" is software whose conditions of propagation,
+modification and use would permit combination with GCC in accord with
+the license of GCC.
+
+"Target Code" refers to output from any compiler for a real or virtual
+target processor architecture, in executable form or suitable for
+input to an assembler, loader, linker and/or execution
+phase. Notwithstanding that, Target Code does not include data in any
+format that is used as a compiler intermediate representation, or used
+for producing a compiler intermediate representation.
+
+The "Compilation Process" transforms code entirely represented in
+non-intermediate languages designed for human-written code, and/or in
+Java Virtual Machine byte code, into Target Code. Thus, for example,
+use of source code generators and preprocessors need not be considered
+part of the Compilation Process, since the Compilation Process can be
+understood as starting with the output of the generators or
+preprocessors.
+
+A Compilation Process is "Eligible" if it is done using GCC, alone or
+with other GPL-compatible software, or if it is done without using any
+work based on GCC. For example, using non-GPL-compatible Software to
+optimize any GCC intermediate representations would not qualify as an
+Eligible Compilation Process.
+
+1. Grant of Additional Permission.
+
+You have permission to propagate a work of Target Code formed by
+combining the Runtime Library with Independent Modules, even if such
+propagation would otherwise violate the terms of GPLv3, provided that
+all Target Code was generated by Eligible Compilation Processes. You
+may then convey such a combination under terms of your choice,
+consistent with the licensing of the Independent Modules.
+
+2. No Weakening of GCC Copyleft.
+
+The availability of this Exception does not imply any general
+presumption that third-party software is unaffected by the copyleft
+requirements of the license of GCC.
+
+----
+
+                    GNU GENERAL PUBLIC LICENSE
+                       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
+
+            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
+state 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 3 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, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program 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, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+        Version 3.1, 31 March 2009
+        
+        Copyright (C) 2009 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.
+        
+        This GCC Runtime Library Exception ("Exception") is an additional
+        permission under section 7 of the GNU General Public License, version
+        3 ("GPLv3"). It applies to a given file (the "Runtime Library") that
+        bears a notice placed by the copyright holder of the file stating that
+        the file is governed by GPLv3 along with this Exception.
+        
+        When you use GCC to compile a program, GCC may combine portions of
+        certain GCC header files and runtime libraries with the compiled
+        program. The purpose of this Exception is to allow compilation of
+        non-GPL (including proprietary) programs to use, in this way, the
+        header files and runtime libraries covered by this Exception.
+        
+        0. Definitions.
+        
+        A file is an "Independent Module" if it either requires the Runtime
+        Library for execution after a Compilation Process, or makes use of an
+        interface provided by the Runtime Library, but is not otherwise based
+        on the Runtime Library.
+        
+        "GCC" means a version of the GNU Compiler Collection, with or without
+        modifications, governed by version 3 (or a specified later version) of
+        the GNU General Public License (GPL) with the option of using any
+        subsequent versions published by the FSF.
+        
+        "GPL-compatible Software" is software whose conditions of propagation,
+        modification and use would permit combination with GCC in accord with
+        the license of GCC.
+        
+        "Target Code" refers to output from any compiler for a real or virtual
+        target processor architecture, in executable form or suitable for
+        input to an assembler, loader, linker and/or execution
+        phase. Notwithstanding that, Target Code does not include data in any
+        format that is used as a compiler intermediate representation, or used
+        for producing a compiler intermediate representation.
+        
+        The "Compilation Process" transforms code entirely represented in
+        non-intermediate languages designed for human-written code, and/or in
+        Java Virtual Machine byte code, into Target Code. Thus, for example,
+        use of source code generators and preprocessors need not be considered
+        part of the Compilation Process, since the Compilation Process can be
+        understood as starting with the output of the generators or
+        preprocessors.
+        
+        A Compilation Process is "Eligible" if it is done using GCC, alone or
+        with other GPL-compatible software, or if it is done without using any
+        work based on GCC. For example, using non-GPL-compatible Software to
+        optimize any GCC intermediate representations would not qualify as an
+        Eligible Compilation Process.
+        
+        1. Grant of Additional Permission.
+        
+        You have permission to propagate a work of Target Code formed by
+        combining the Runtime Library with Independent Modules, even if such
+        propagation would otherwise violate the terms of GPLv3, provided that
+        all Target Code was generated by Eligible Compilation Processes. You
+        may then convey such a combination under terms of your choice,
+        consistent with the licensing of the Independent Modules.
+        
+        2. No Weakening of GCC Copyleft.
+        
+        The availability of this Exception does not imply any general
+        presumption that third-party software is unaffected by the copyleft
+        requirements of the license of GCC.

+                               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
+        
+                    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
+        state 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 3 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, see <http://www.gnu.org/licenses/>.
+        
+        Also add information on how to contact you by electronic and paper mail.
+        
+          If the program does terminal interaction, make it output a short
+        notice like this when it starts in an interactive mode:
+        
+            <program>  Copyright (C) <year>  <name of author>
+            This program 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, your program's commands
+        might be different; for a GUI interface, you would use an "about box".
+        
+          You should also get your employer (if you work as a programmer) or school,
+        if any, to sign a "copyright disclaimer" for the program, if necessary.
+        For more information on this, and how to apply and follow the GNU GPL, see
+        <http://www.gnu.org/licenses/>.
+        
+          The GNU General Public License does not permit incorporating your program
+        into proprietary programs.  If your program is a subroutine library, you
+        may consider it more useful to permit linking proprietary applications with

+"""
+.. note:
+    If you are looking for overrides for NumPy-specific methods, see the
+    documentation for :obj:`unumpy`. This page explains how to write
+    back-ends and multimethods.
+
+``uarray`` is built around a back-end protocol, and overridable multimethods.
+It is necessary to define multimethods for back-ends to be able to override them.
+See the documentation of :obj:`generate_multimethod` on how to write multimethods.
+
+
+
+Let's start with the simplest:
+
+``__ua_domain__`` defines the back-end *domain*. The domain consists of period-
+separated string consisting of the modules you extend plus the submodule. For
+example, if a submodule ``module2.submodule`` extends ``module1``
+(i.e., it exposes dispatchables marked as types available in ``module1``),
+then the domain string should be ``"module1.module2.submodule"``.
+
+
+For the purpose of this demonstration, we'll be creating an object and setting
+its attributes directly. However, note that you can use a module or your own type
+as a backend as well.
+
+>>> class Backend: pass
+>>> be = Backend()
+>>> be.__ua_domain__ = "ua_examples"
+
+It might be useful at this point to sidetrack to the documentation of
+:obj:`generate_multimethod` to find out how to generate a multimethod
+overridable by :obj:`uarray`. Needless to say, writing a backend and
+creating multimethods are mostly orthogonal activities, and knowing
+one doesn't necessarily require knowledge of the other, although it
+is certainly helpful. We expect core API designers/specifiers to write the
+multimethods, and implementors to override them. But, as is often the case,
+similar people write both.
+
+Without further ado, here's an example multimethod:
+
+>>> import uarray as ua
+>>> from uarray import Dispatchable
+>>> def override_me(a, b):
+...   return Dispatchable(a, int),
+>>> def override_replacer(args, kwargs, dispatchables):
+...     return (dispatchables[0], args[1]), {}
+>>> overridden_me = ua.generate_multimethod(
+...     override_me, override_replacer, "ua_examples"
+... )
+
+Next comes the part about overriding the multimethod. This requires
+the ``__ua_function__`` protocol, and the ``__ua_convert__``
+protocol. The ``__ua_function__`` protocol has the signature
+``(method, args, kwargs)`` where ``method`` is the passed
+multimethod, ``args``/``kwargs`` specify the arguments and ``dispatchables``
+is the list of converted dispatchables passed in.
+
+>>> def __ua_function__(method, args, kwargs):
+...     return method.__name__, args, kwargs
+>>> be.__ua_function__ = __ua_function__
+
+The other protocol of interest is the ``__ua_convert__`` protocol. It has the
+signature ``(dispatchables, coerce)``. When ``coerce`` is ``False``, conversion
+between the formats should ideally be an ``O(1)`` operation, but it means that
+no memory copying should be involved, only views of the existing data.
+
+>>> def __ua_convert__(dispatchables, coerce):
+...     for d in dispatchables:
+...         if d.type is int:
+...             if coerce and d.coercible:
+...                 yield str(d.value)
+...             else:
+...                 yield d.value
+>>> be.__ua_convert__ = __ua_convert__
+
+Now that we have defined the backend, the next thing to do is to call the multimethod.
+
+>>> with ua.set_backend(be):
+...      overridden_me(1, "2")
+('override_me', (1, '2'), {})
+
+Note that the marked type has no effect on the actual type of the passed object.
+We can also coerce the type of the input.
+
+>>> with ua.set_backend(be, coerce=True):
+...     overridden_me(1, "2")
+...     overridden_me(1.0, "2")
+('override_me', ('1', '2'), {})
+('override_me', ('1.0', '2'), {})
+
+Another feature is that if you remove ``__ua_convert__``, the arguments are not
+converted at all and it's up to the backend to handle that.
+
+>>> del be.__ua_convert__
+>>> with ua.set_backend(be):
+...     overridden_me(1, "2")
+('override_me', (1, '2'), {})
+
+You also have the option to return ``NotImplemented``, in which case processing moves on
+to the next back-end, which in this case, doesn't exist. The same applies to
+``__ua_convert__``.
+
+>>> be.__ua_function__ = lambda *a, **kw: NotImplemented
+>>> with ua.set_backend(be):
+...     overridden_me(1, "2")
+Traceback (most recent call last):
+    ...
+uarray.BackendNotImplementedError: ...
+
+The last possibility is if we don't have ``__ua_convert__``, in which case the job is
+left up to ``__ua_function__``, but putting things back into arrays after conversion
+will not be possible.

+
+    ``res`` is an object of ``TypeB`` because ``BackendB`` is set in the

+    This won't call ``BackendBC`` because it doesn't support ``TypeA``.
