-   the Free Software Foundation, either version 3 of the License, or
-   (at your option) any later version.
+                            Preamble
 
-   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.
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
 
-   You should have received a copy of the GNU General Public License
-   along with this program.  If not, see <http://www.gnu.org/licenses/>.
+  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.
 
-   As a special exception, you may create a larger work that contains
-   part or all of the Bison parser skeleton and distribute that work
-   under terms of your choice, so long as that work isn't itself a
-   parser generator using the skeleton or a modified version thereof
-   as a parser skeleton.  Alternatively, if you modify or redistribute
-   the parser skeleton itself, you may (at your option) remove this
-   special exception, which will cause the skeleton and the resulting
-   Bison output files to be licensed under the GNU General Public
-   License without this special exception.
+  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.
 
-   This special exception was added by the Free Software Foundation in
-   version 2.2 of Bison.
+  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.
+
+Bison Exception
+
+As a special exception, you may create a larger work that contains part or all
+of the Bison parser skeleton and distribute that work under terms of your
+choice, so long as that work isn't itself a parser generator using the skeleton
+or a modified version thereof as a parser skeleton.  Alternatively, if you
+modify or redistribute the parser skeleton itself, you may (at your option)
+remove this special exception, which will cause the skeleton and the resulting
+Bison output files to be licensed under the GNU General Public License without
+this special exception.
+
+This special exception was added by the Free Software Foundation in version
+2.2 of Bison.
+
+                     END OF TERMS AND CONDITIONS

+of the attribution notices contained within such NOTICE file, excluding those
+notices that do not pertain to any part of the Derivative Works, in at least
+one of the following places: within a NOTICE text file distributed as part
+of the Derivative Works; within the Source form or documentation, if provided
+along with the Derivative Works; or, within a display generated by the Derivative
+Works, if and wherever such third-party notices normally appear. The contents

+as modifying the License.
+
+You may add Your own copyright statement to Your modifications and may provide
+additional or different license terms and conditions for use, reproduction,
+or distribution of Your modifications, or for any such Derivative Works as
+a whole, provided Your use, reproduction, and distribution of the Work otherwise
+complies with the conditions stated in this License.

+
+7. Disclaimer of Warranty. Unless required by applicable law or agreed to
+in writing, Licensor provides the Work (and each Contributor provides its
+Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
+KIND, either express or implied, including, without limitation, any warranties
+or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR
+A PARTICULAR PURPOSE. You are solely responsible for determining the appropriateness
+of using or redistributing the Work and assume any risks associated with Your
+exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory, whether
+in tort (including negligence), contract, or otherwise, unless required by
+applicable law (such as deliberate and grossly negligent acts) or agreed to
+in writing, shall any Contributor be liable to You for damages, including
+any direct, indirect, special, incidental, or consequential damages of any
+character arising as a result of this License or out of the use or inability
+to use the Work (including but not limited to damages for loss of goodwill,
+work stoppage, computer failure or malfunction, or any and all other commercial
+damages or losses), even if such Contributor has been advised of the possibility
+of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing the Work
+or Derivative Works thereof, You may choose to offer, and charge a fee for,
+acceptance of support, warranty, indemnity, or other liability obligations
+and/or rights consistent with this License. However, in accepting such obligations,
+You may act only on Your own behalf and on Your sole responsibility, not on
+behalf of any other Contributor, and only if You agree to indemnify, defend,
+and hold each Contributor harmless for any liability incurred by, or claims
+asserted against, such Contributor by reason of your accepting any such warranty

+Using Creative Commons Public Licenses
+
+Creative Commons public licenses provide a standard set of terms and conditions
+that creators and other rights holders may use to share original works of
+authorship and other material subject to copyright and certain other rights
+specified in the public license below. The following considerations are for
+informational purposes only, are not exhaustive, and do not form part of our
+licenses.
+
+Considerations for licensors: Our public licenses are intended for use by
+those authorized to give the public permission to use material in ways otherwise
+restricted by copyright and certain other rights. Our licenses are irrevocable.
+Licensors should read and understand the terms and conditions of the license
+they choose before applying it. Licensors should also secure all rights necessary
+before applying our licenses so that the public can reuse the material as
+expected. Licensors should clearly mark any material not subject to the license.
+This includes other CC-licensed material, or material used under an exception
+or limitation to copyright. More considerations for licensors : wiki.creativecommons.org/Considerations_for_licensors

+Considerations for the public: By using one of our public licenses, a licensor
+grants the public permission to use the licensed material under specified
+terms and conditions. If the licensor's permission is not necessary for any
+reason–for example, because of any applicable exception or limitation to copyright–then
+that use is not regulated by the license. Our licenses grant only permissions
+under copyright and certain other rights that a licensor has authority to
+grant. Use of the licensed material may still be restricted for other reasons,
+including because others have copyright or other rights in the material. A
+licensor may make special requests, such as asking that all changes be marked
+or described. Although not required by our licenses, you are encouraged to
+respect those requests where reasonable. More considerations for the public

+
+By exercising the Licensed Rights (defined below), You accept and agree to
+be bound by the terms and conditions of this Creative Commons Attribution
+4.0 International Public License ("Public License"). To the extent this Public
+License may be interpreted as a contract, You are granted the Licensed Rights
+in consideration of Your acceptance of these terms and conditions, and the
+Licensor grants You such rights in consideration of benefits the Licensor
+receives from making the Licensed Material available under these terms and
+conditions.
+
+Section 1 – Definitions.
+
+a. Adapted Material means material subject to Copyright and Similar Rights
+that is derived from or based upon the Licensed Material and in which the
+Licensed Material is translated, altered, arranged, transformed, or otherwise
+modified in a manner requiring permission under the Copyright and Similar
+Rights held by the Licensor. For purposes of this Public License, where the
+Licensed Material is a musical work, performance, or sound recording, Adapted
+Material is always produced where the Licensed Material is synched in timed
+relation with a moving image.
+
+b. Adapter's License means the license You apply to Your Copyright and Similar
+Rights in Your contributions to Adapted Material in accordance with the terms
+and conditions of this Public License.
+
+c. Copyright and Similar Rights means copyright and/or similar rights closely
+related to copyright including, without limitation, performance, broadcast,
+sound recording, and Sui Generis Database Rights, without regard to how the
+rights are labeled or categorized. For purposes of this Public License, the
+rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.
+
+d. Effective Technological Measures means those measures that, in the absence
+of proper authority, may not be circumvented under laws fulfilling obligations
+under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996,
+and/or similar international agreements.
+
+e. Exceptions and Limitations means fair use, fair dealing, and/or any other
+exception or limitation to Copyright and Similar Rights that applies to Your
+use of the Licensed Material.
+
+f. Licensed Material means the artistic or literary work, database, or other
+material to which the Licensor applied this Public License.
+
+g. Licensed Rights means the rights granted to You subject to the terms and
+conditions of this Public License, which are limited to all Copyright and
+Similar Rights that apply to Your use of the Licensed Material and that the
+Licensor has authority to license.
+
+h. Licensor means the individual(s) or entity(ies) granting rights under this
+Public License.
+
+i. Share means to provide material to the public by any means or process that
+requires permission under the Licensed Rights, such as reproduction, public
+display, public performance, distribution, dissemination, communication, or
+importation, and to make material available to the public including in ways
+that members of the public may access the material from a place and at a time
+individually chosen by them.
+
+j. Sui Generis Database Rights means rights other than copyright resulting
+from Directive 96/9/EC of the European Parliament and of the Council of 11
+March 1996 on the legal protection of databases, as amended and/or succeeded,
+as well as other essentially equivalent rights anywhere in the world.
+
+k. You means the individual or entity exercising the Licensed Rights under
+this Public License. Your has a corresponding meaning.
+
+Section 2 – Scope.
+
+   a. License grant.
+
+1. Subject to the terms and conditions of this Public License, the Licensor
+hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive,
+irrevocable license to exercise the Licensed Rights in the Licensed Material
+to:
+
+         A. reproduce and Share the Licensed Material, in whole or in part; and
+
+         B. produce, reproduce, and Share Adapted Material.
+
+2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions
+and Limitations apply to Your use, this Public License does not apply, and
+You do not need to comply with its terms and conditions.
+
+      3. Term. The term of this Public License is specified in Section 6(a).
+
+4. Media and formats; technical modifications allowed. The Licensor authorizes
+You to exercise the Licensed Rights in all media and formats whether now known
+or hereafter created, and to make technical modifications necessary to do
+so. The Licensor waives and/or agrees not to assert any right or authority
+to forbid You from making technical modifications necessary to exercise the
+Licensed Rights, including technical modifications necessary to circumvent
+Effective Technological Measures. For purposes of this Public License, simply
+making modifications authorized by this Section 2(a)(4) never produces Adapted
+Material.
+
+      5. Downstream recipients.
+
+A. Offer from the Licensor – Licensed Material. Every recipient of the Licensed
+Material automatically receives an offer from the Licensor to exercise the
+Licensed Rights under the terms and conditions of this Public License.
+
+B. No downstream restrictions. You may not offer or impose any additional
+or different terms or conditions on, or apply any Effective Technological
+Measures to, the Licensed Material if doing so restricts exercise of the Licensed
+Rights by any recipient of the Licensed Material.
+
+6. No endorsement. Nothing in this Public License constitutes or may be construed
+as permission to assert or imply that You are, or that Your use of the Licensed
+Material is, connected with, or sponsored, endorsed, or granted official status
+by, the Licensor or others designated to receive attribution as provided in
+Section 3(a)(1)(A)(i).
+
+   b. Other rights.
+
+1. Moral rights, such as the right of integrity, are not licensed under this
+Public License, nor are publicity, privacy, and/or other similar personality
+rights; however, to the extent possible, the Licensor waives and/or agrees
+not to assert any such rights held by the Licensor to the limited extent necessary
+to allow You to exercise the Licensed Rights, but not otherwise.
+
+2. Patent and trademark rights are not licensed under this Public License.
+
+3. To the extent possible, the Licensor waives any right to collect royalties
+from You for the exercise of the Licensed Rights, whether directly or through
+a collecting society under any voluntary or waivable statutory or compulsory
+licensing scheme. In all other cases the Licensor expressly reserves any right
+to collect such royalties.
+
+Section 3 – License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the following
+conditions.
+
+   a. Attribution.
+
+1. If You Share the Licensed Material (including in modified form), You must:
+
+A. retain the following if it is supplied by the Licensor with the Licensed
+Material:
+
+i. identification of the creator(s) of the Licensed Material and any others
+designated to receive attribution, in any reasonable manner requested by the
+Licensor (including by pseudonym if designated);
+
+            ii. a copyright notice;
+
+            iii. a notice that refers to this Public License;
+
+            iv. a notice that refers to the disclaimer of warranties;
+
+v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable;
+
+B. indicate if You modified the Licensed Material and retain an indication
+of any previous modifications; and
+
+C. indicate the Licensed Material is licensed under this Public License, and
+include the text of, or the URI or hyperlink to, this Public License.
+
+2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner
+based on the medium, means, and context in which You Share the Licensed Material.
+For example, it may be reasonable to satisfy the conditions by providing a
+URI or hyperlink to a resource that includes the required information.
+
+3. If requested by the Licensor, You must remove any of the information required
+by Section 3(a)(1)(A) to the extent reasonably practicable.
+
+4. If You Share Adapted Material You produce, the Adapter's License You apply
+must not prevent recipients of the Adapted Material from complying with this
+Public License.
+
+Section 4 – Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that apply to
+Your use of the Licensed Material:
+
+a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract,
+reuse, reproduce, and Share all or a substantial portion of the contents of
+the database;
+
+b. if You include all or a substantial portion of the database contents in
+a database in which You have Sui Generis Database Rights, then the database
+in which You have Sui Generis Database Rights (but not its individual contents)
+is Adapted Material; and
+
+c. You must comply with the conditions in Section 3(a) if You Share all or
+a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not replace
+Your obligations under this Public License where the Licensed Rights include
+other Copyright and Similar Rights.
+
+Section 5 – Disclaimer of Warranties and Limitation of Liability.
+
+a. Unless otherwise separately undertaken by the Licensor, to the extent possible,
+the Licensor offers the Licensed Material as-is and as-available, and makes
+no representations or warranties of any kind concerning the Licensed Material,
+whether express, implied, statutory, or other. This includes, without limitation,
+warranties of title, merchantability, fitness for a particular purpose, non-infringement,
+absence of latent or other defects, accuracy, or the presence or absence of
+errors, whether or not known or discoverable. Where disclaimers of warranties
+are not allowed in full or in part, this disclaimer may not apply to You.
+
+b. To the extent possible, in no event will the Licensor be liable to You
+on any legal theory (including, without limitation, negligence) or otherwise
+for any direct, special, indirect, incidental, consequential, punitive, exemplary,
+or other losses, costs, expenses, or damages arising out of this Public License
+or use of the Licensed Material, even if the Licensor has been advised of
+the possibility of such losses, costs, expenses, or damages. Where a limitation
+of liability is not allowed in full or in part, this limitation may not apply
+to You.
+
+c. The disclaimer of warranties and limitation of liability provided above
+shall be interpreted in a manner that, to the extent possible, most closely
+approximates an absolute disclaimer and waiver of all liability.
+
+Section 6 – Term and Termination.
+
+a. This Public License applies for the term of the Copyright and Similar Rights
+licensed here. However, if You fail to comply with this Public License, then
+Your rights under this Public License terminate automatically.
+
+b. Where Your right to use the Licensed Material has terminated under Section
+6(a), it reinstates:
+
+1. automatically as of the date the violation is cured, provided it is cured
+within 30 days of Your discovery of the violation; or
+
+      2. upon express reinstatement by the Licensor.
+
+c. For the avoidance of doubt, this Section 6(b) does not affect any right
+the Licensor may have to seek remedies for Your violations of this Public
+License.
+
+d. For the avoidance of doubt, the Licensor may also offer the Licensed Material
+under separate terms or conditions or stop distributing the Licensed Material
+at any time; however, doing so will not terminate this Public License.
+
+   e. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.
+
+Section 7 – Other Terms and Conditions.
+
+a. The Licensor shall not be bound by any additional or different terms or
+conditions communicated by You unless expressly agreed.
+
+b. Any arrangements, understandings, or agreements regarding the Licensed
+Material not stated herein are separate from and independent of the terms
+and conditions of this Public License.
+
+Section 8 – Interpretation.
+
+a. For the avoidance of doubt, this Public License does not, and shall not
+be interpreted to, reduce, limit, restrict, or impose conditions on any use
+of the Licensed Material that could lawfully be made without permission under
+this Public License.
+
+b. To the extent possible, if any provision of this Public License is deemed
+unenforceable, it shall be automatically reformed to the minimum extent necessary
+to make it enforceable. If the provision cannot be reformed, it shall be severed
+from this Public License without affecting the enforceability of the remaining
+terms and conditions.
+
+c. No term or condition of this Public License will be waived and no failure
+to comply consented to unless expressly agreed to by the Licensor.
+
+d. Nothing in this Public License constitutes or may be interpreted as a limitation
+upon, or waiver of, any privileges and immunities that apply to the Licensor
+or You, including from the legal processes of any jurisdiction or authority.

 If your target is Vulkan GLSL, `--vulkan-semantics` will emit separate image samplers as you'd expect.
 The command line client calls `Compiler::build_combined_image_samplers` automatically, but if you're calling the library, you'll need to do this yourself.

+#### Descriptor sets (Vulkan GLSL) for backends which do not support them (pre HLSL 5.1 / GLSL)
 
 Descriptor sets are unique to Vulkan, so make sure that descriptor set + binding is remapped to a flat binding scheme (set always 0), so that other APIs can make sense of the bindings.
-This can be done with `Compiler::set_decoration(id, spv::DecorationDescriptorSet)`.
+This can be done with `Compiler::set_decoration(id, spv::DecorationDescriptorSet)`. For other backends like MSL and HLSL, descriptor sets
+can be used, with some minor caveats, see below.
+
+##### MSL 2.0+
+
+Metal supports indirect argument buffers (--msl-argument-buffers). In this case, descriptor sets become argument buffers,
+and bindings are mapped to [[id(N)]] within the argument buffer. One quirk is that arrays of resources consume multiple ids,
+where Vulkan does not. This can be worked around either from shader authoring stage
+or remapping bindings as needed to avoid the overlap.
+There is also a rich API to declare remapping schemes which is intended to work like
+the pipeline layout in Vulkan. See `CompilerMSL::add_msl_resource_binding`. Remapping combined image samplers for example
+must be split into two bindings in MSL, so it's possible to declare an id for the texture and sampler binding separately.
+
+##### HLSL - SM 5.1+
+
+In SM 5.1+, descriptor set bindings are interpreted as register spaces directly. In HLSL however, arrays of resources consume
+multiple binding slots where Vulkan does not, so there might be overlap if the SPIR-V was not authored with this in mind.
+This can be worked around either from shader authoring stage (don't assign overlapping bindings)
+or remap bindings in SPIRV-Cross as needed to avoid the overlap.
