        GNU LESSER 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.
        
        
          This version of the GNU Lesser General Public License incorporates
        the terms and conditions of version 3 of the GNU General Public
        License, supplemented by the additional permissions listed below.
        
          0. Additional Definitions.
        
          As used herein, "this License" refers to version 3 of the GNU Lesser
        General Public License, and the "GNU GPL" refers to version 3 of the GNU
        General Public License.
        
          "The Library" refers to a covered work governed by this License,
        other than an Application or a Combined Work as defined below.
        
          An "Application" is any work that makes use of an interface provided
        by the Library, but which is not otherwise based on the Library.
        Defining a subclass of a class defined by the Library is deemed a mode
        of using an interface provided by the Library.
        
          A "Combined Work" is a work produced by combining or linking an
        Application with the Library.  The particular version of the Library
        with which the Combined Work was made is also called the "Linked
        Version".
        
          The "Minimal Corresponding Source" for a Combined Work means the
        Corresponding Source for the Combined Work, excluding any source code
        for portions of the Combined Work that, considered in isolation, are
        based on the Application, and not on the Linked Version.
        
          The "Corresponding Application Code" for a Combined Work means the
        object code and/or source code for the Application, including any data
        and utility programs needed for reproducing the Combined Work from the
        Application, but excluding the System Libraries of the Combined Work.
        
          1. Exception to Section 3 of the GNU GPL.
        
          You may convey a covered work under sections 3 and 4 of this License
        without being bound by section 3 of the GNU GPL.
        
          2. Conveying Modified Versions.
        
          If you modify a copy of the Library, and, in your modifications, a
        facility refers to a function or data to be supplied by an Application
        that uses the facility (other than as an argument passed when the
        facility is invoked), then you may convey a copy of the modified
        version:
        
           a) under this License, provided that you make a good faith effort to
           ensure that, in the event an Application does not supply the
           function or data, the facility still operates, and performs
           whatever part of its purpose remains meaningful, or
        
           b) under the GNU GPL, with none of the additional permissions of
           this License applicable to that copy.
        
          3. Object Code Incorporating Material from Library Header Files.
        
          The object code form of an Application may incorporate material from
        a header file that is part of the Library.  You may convey such object
        code under terms of your choice, provided that, if the incorporated
        material is not limited to numerical parameters, data structure
        layouts and accessors, or small macros, inline functions and templates
        (ten or fewer lines in length), you do both of the following:
        
           a) Give prominent notice with each copy of the object code that the
           Library is used in it and that the Library and its use are
           covered by this License.
        
           b) Accompany the object code with a copy of the GNU GPL and this license
           document.
        
          4. Combined Works.
        
          You may convey a Combined Work under terms of your choice that,
        taken together, effectively do not restrict modification of the
        portions of the Library contained in the Combined Work and reverse
        engineering for debugging such modifications, if you also do each of
        the following:
        
           a) Give prominent notice with each copy of the Combined Work that
           the Library is used in it and that the Library and its use are
           covered by this License.
        
           b) Accompany the Combined Work with a copy of the GNU GPL and this license
           document.
        
           c) For a Combined Work that displays copyright notices during
           execution, include the copyright notice for the Library among
           these notices, as well as a reference directing the user to the
           copies of the GNU GPL and this license document.
        
           d) Do one of the following:
        
               0) Convey the Minimal Corresponding Source under the terms of this
               License, and the Corresponding Application Code in a form
               suitable for, and under terms that permit, the user to
               recombine or relink the Application with a modified version of
               the Linked Version to produce a modified Combined Work, in the
               manner specified by section 6 of the GNU GPL for conveying
               Corresponding Source.
        
               1) Use a suitable shared library mechanism for linking with the
               Library.  A suitable mechanism is one that (a) uses at run time
               a copy of the Library already present on the user's computer
               system, and (b) will operate properly with a modified version
               of the Library that is interface-compatible with the Linked
               Version.
        
           e) Provide Installation Information, but only if you would otherwise
           be required to provide such information under section 6 of the
           GNU GPL, and only to the extent that such information is
           necessary to install and execute a modified version of the
           Combined Work produced by recombining or relinking the
           Application with a modified version of the Linked Version. (If
           you use option 4d0, the Installation Information must accompany
           the Minimal Corresponding Source and Corresponding Application
           Code. If you use option 4d1, you must provide the Installation
           Information in the manner specified by section 6 of the GNU GPL
           for conveying Corresponding Source.)
        
          5. Combined Libraries.
        
          You may place library facilities that are a work based on the
        Library side by side in a single library together with other library
        facilities that are not Applications and are not covered by this
        License, and convey such a combined library under terms of your
        choice, if you do both of the following:
        
           a) Accompany the combined library with a copy of the same work based
           on the Library, uncombined with any other library facilities,
           conveyed under the terms of this License.
        
           b) Give prominent notice with the combined library that part of it
           is a work based on the Library, and explaining where to find the
           accompanying uncombined form of the same work.
        
          6. Revised Versions of the GNU Lesser General Public License.
        
          The Free Software Foundation may publish revised and/or new versions
        of the GNU Lesser 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
        Library as you received it specifies that a certain numbered version
        of the GNU Lesser General Public License "or any later version"
        applies to it, you have the option of following the terms and
        conditions either of that published version or of any later version
        published by the Free Software Foundation. If the Library as you
        received it does not specify a version number of the GNU Lesser
        General Public License, you may choose any version of the GNU Lesser
        General Public License ever published by the Free Software Foundation.
        
          If the Library as you received it specifies that a proxy can decide
        whether future versions of the GNU Lesser General Public License shall
        apply, that proxy's public statement of acceptance of any version is
        permanent authorization for you to choose that version for the
        Library.

         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 1.3, 3 November 2008

         Everyone is permitted to copy and distribute verbatim copies
         of this license document, but changing it is not allowed.
        
        0. PREAMBLE
        
        The purpose of this License is to make a manual, textbook, or other
        functional and useful document "free" in the sense of freedom: to
        assure everyone the effective freedom to copy and redistribute it,
        with or without modifying it, either commercially or noncommercially.
        Secondarily, this License preserves for the author and publisher a way
        to get credit for their work, while not being considered responsible
        for modifications made by others.
        
        This License is a kind of "copyleft", which means that derivative
        works of the document must themselves be free in the same sense.  It
        complements the GNU General Public License, which is a copyleft
        license designed for free software.
        
        We have designed this License in order to use it for manuals for free
        software, because free software needs free documentation: a free
        program should come with manuals providing the same freedoms that the
        software does.  But this License is not limited to software manuals;
        it can be used for any textual work, regardless of subject matter or
        whether it is published as a printed book.  We recommend this License
        principally for works whose purpose is instruction or reference.
        
        
        1. APPLICABILITY AND DEFINITIONS
        
        This License applies to any manual or other work, in any medium, that
        contains a notice placed by the copyright holder saying it can be
        distributed under the terms of this License.  Such a notice grants a
        world-wide, royalty-free license, unlimited in duration, to use that
        work under the conditions stated herein.  The "Document", below,
        refers to any such manual or work.  Any member of the public is a
        licensee, and is addressed as "you".  You accept the license if you
        copy, modify or distribute the work in a way requiring permission
        under copyright law.
        
        A "Modified Version" of the Document means any work containing the
        Document or a portion of it, either copied verbatim, or with
        modifications and/or translated into another language.
        
        A "Secondary Section" is a named appendix or a front-matter section of
        the Document that deals exclusively with the relationship of the
        publishers or authors of the Document to the Document's overall
        subject (or to related matters) and contains nothing that could fall
        directly within that overall subject.  (Thus, if the Document is in
        part a textbook of mathematics, a Secondary Section may not explain
        any mathematics.)  The relationship could be a matter of historical
        connection with the subject or with related matters, or of legal,
        commercial, philosophical, ethical or political position regarding
        them.
        
        The "Invariant Sections" are certain Secondary Sections whose titles
        are designated, as being those of Invariant Sections, in the notice
        that says that the Document is released under this License.  If a
        section does not fit the above definition of Secondary then it is not
        allowed to be designated as Invariant.  The Document may contain zero
        Invariant Sections.  If the Document does not identify any Invariant
        Sections then there are none.
        
        The "Cover Texts" are certain short passages of text that are listed,
        as Front-Cover Texts or Back-Cover Texts, in the notice that says that
        the Document is released under this License.  A Front-Cover Text may
        be at most 5 words, and a Back-Cover Text may be at most 25 words.
        
        A "Transparent" copy of the Document means a machine-readable copy,
        represented in a format whose specification is available to the
        general public, that is suitable for revising the document
        straightforwardly with generic text editors or (for images composed of
        pixels) generic paint programs or (for drawings) some widely available
        drawing editor, and that is suitable for input to text formatters or
        for automatic translation to a variety of formats suitable for input
        to text formatters.  A copy made in an otherwise Transparent file
        format whose markup, or absence of markup, has been arranged to thwart
        or discourage subsequent modification by readers is not Transparent.
        An image format is not Transparent if used for any substantial amount
        of text.  A copy that is not "Transparent" is called "Opaque".
        
        Examples of suitable formats for Transparent copies include plain
        ASCII without markup, Texinfo input format, LaTeX input format, SGML
        or XML using a publicly available DTD, and standard-conforming simple
        HTML, PostScript or PDF designed for human modification.  Examples of
        transparent image formats include PNG, XCF and JPG.  Opaque formats
        include proprietary formats that can be read and edited only by
        proprietary word processors, SGML or XML for which the DTD and/or
        processing tools are not generally available, and the
        machine-generated HTML, PostScript or PDF produced by some word
        processors for output purposes only.
        
        The "Title Page" means, for a printed book, the title page itself,
        plus such following pages as are needed to hold, legibly, the material
        this License requires to appear in the title page.  For works in
        formats which do not have any title page as such, "Title Page" means
        the text near the most prominent appearance of the work's title,
        preceding the beginning of the body of the text.
        
        The "publisher" means any person or entity that distributes copies of
        the Document to the public.
        
        A section "Entitled XYZ" means a named subunit of the Document whose
        title either is precisely XYZ or contains XYZ in parentheses following
        text that translates XYZ in another language.  (Here XYZ stands for a
        specific section name mentioned below, such as "Acknowledgements",
        "Dedications", "Endorsements", or "History".)  To "Preserve the Title"
        of such a section when you modify the Document means that it remains a
        section "Entitled XYZ" according to this definition.
        
        The Document may include Warranty Disclaimers next to the notice which
        states that this License applies to the Document.  These Warranty
        Disclaimers are considered to be included by reference in this
        License, but only as regards disclaiming warranties: any other
        implication that these Warranty Disclaimers may have is void and has
        no effect on the meaning of this License.
        
        2. VERBATIM COPYING
        
        You may copy and distribute the Document in any medium, either
        commercially or noncommercially, provided that this License, the
        copyright notices, and the license notice saying this License applies
        to the Document are reproduced in all copies, and that you add no
        other conditions whatsoever to those of this License.  You may not use
        technical measures to obstruct or control the reading or further
        copying of the copies you make or distribute.  However, you may accept
        compensation in exchange for copies.  If you distribute a large enough
        number of copies you must also follow the conditions in section 3.
        
        You may also lend copies, under the same conditions stated above, and
        you may publicly display copies.
        
        
        3. COPYING IN QUANTITY
        
        If you publish printed copies (or copies in media that commonly have
        printed covers) of the Document, numbering more than 100, and the
        Document's license notice requires Cover Texts, you must enclose the
        copies in covers that carry, clearly and legibly, all these Cover
        Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
        the back cover.  Both covers must also clearly and legibly identify
        you as the publisher of these copies.  The front cover must present
        the full title with all words of the title equally prominent and
        visible.  You may add other material on the covers in addition.
        Copying with changes limited to the covers, as long as they preserve
        the title of the Document and satisfy these conditions, can be treated
        as verbatim copying in other respects.
        
        If the required texts for either cover are too voluminous to fit
        legibly, you should put the first ones listed (as many as fit
        reasonably) on the actual cover, and continue the rest onto adjacent
        pages.
        
        If you publish or distribute Opaque copies of the Document numbering
        more than 100, you must either include a machine-readable Transparent
        copy along with each Opaque copy, or state in or with each Opaque copy
        a computer-network location from which the general network-using
        public has access to download using public-standard network protocols
        a complete Transparent copy of the Document, free of added material.
        If you use the latter option, you must take reasonably prudent steps,
        when you begin distribution of Opaque copies in quantity, to ensure
        that this Transparent copy will remain thus accessible at the stated
        location until at least one year after the last time you distribute an
        Opaque copy (directly or through your agents or retailers) of that
        edition to the public.
        
        It is requested, but not required, that you contact the authors of the
        Document well before redistributing any large number of copies, to
        give them a chance to provide you with an updated version of the
        Document.
        
        
        4. MODIFICATIONS
        
        You may copy and distribute a Modified Version of the Document under
        the conditions of sections 2 and 3 above, provided that you release
        the Modified Version under precisely this License, with the Modified
        Version filling the role of the Document, thus licensing distribution
        and modification of the Modified Version to whoever possesses a copy
        of it.  In addition, you must do these things in the Modified Version:
        
        A. Use in the Title Page (and on the covers, if any) a title distinct
           from that of the Document, and from those of previous versions
           (which should, if there were any, be listed in the History section
           of the Document).  You may use the same title as a previous version
           if the original publisher of that version gives permission.
        B. List on the Title Page, as authors, one or more persons or entities
           responsible for authorship of the modifications in the Modified
           Version, together with at least five of the principal authors of the
           Document (all of its principal authors, if it has fewer than five),
           unless they release you from this requirement.
        C. State on the Title page the name of the publisher of the
           Modified Version, as the publisher.
        D. Preserve all the copyright notices of the Document.
        E. Add an appropriate copyright notice for your modifications
           adjacent to the other copyright notices.
        F. Include, immediately after the copyright notices, a license notice
           giving the public permission to use the Modified Version under the
           terms of this License, in the form shown in the Addendum below.
        G. Preserve in that license notice the full lists of Invariant Sections
           and required Cover Texts given in the Document's license notice.
        H. Include an unaltered copy of this License.
        I. Preserve the section Entitled "History", Preserve its Title, and add
           to it an item stating at least the title, year, new authors, and
           publisher of the Modified Version as given on the Title Page.  If
           there is no section Entitled "History" in the Document, create one
           stating the title, year, authors, and publisher of the Document as
           given on its Title Page, then add an item describing the Modified
           Version as stated in the previous sentence.
        J. Preserve the network location, if any, given in the Document for
           public access to a Transparent copy of the Document, and likewise
           the network locations given in the Document for previous versions
           it was based on.  These may be placed in the "History" section.
           You may omit a network location for a work that was published at
           least four years before the Document itself, or if the original
           publisher of the version it refers to gives permission.
        K. For any section Entitled "Acknowledgements" or "Dedications",
           Preserve the Title of the section, and preserve in the section all
           the substance and tone of each of the contributor acknowledgements
           and/or dedications given therein.
        L. Preserve all the Invariant Sections of the Document,
           unaltered in their text and in their titles.  Section numbers
           or the equivalent are not considered part of the section titles.
        M. Delete any section Entitled "Endorsements".  Such a section
           may not be included in the Modified Version.
        N. Do not retitle any existing section to be Entitled "Endorsements"
           or to conflict in title with any Invariant Section.
        O. Preserve any Warranty Disclaimers.
        
        If the Modified Version includes new front-matter sections or
        appendices that qualify as Secondary Sections and contain no material
        copied from the Document, you may at your option designate some or all
        of these sections as invariant.  To do this, add their titles to the
        list of Invariant Sections in the Modified Version's license notice.
        These titles must be distinct from any other section titles.
        
        You may add a section Entitled "Endorsements", provided it contains
        nothing but endorsements of your Modified Version by various
        parties--for example, statements of peer review or that the text has
        been approved by an organization as the authoritative definition of a
        standard.
        
        You may add a passage of up to five words as a Front-Cover Text, and a
        passage of up to 25 words as a Back-Cover Text, to the end of the list
        of Cover Texts in the Modified Version.  Only one passage of
        Front-Cover Text and one of Back-Cover Text may be added by (or
        through arrangements made by) any one entity.  If the Document already
        includes a cover text for the same cover, previously added by you or
        by arrangement made by the same entity you are acting on behalf of,
        you may not add another; but you may replace the old one, on explicit
        permission from the previous publisher that added the old one.
        
        The author(s) and publisher(s) of the Document do not by this License
        give permission to use their names for publicity for or to assert or
        imply endorsement of any Modified Version.
        
        
        5. COMBINING DOCUMENTS
        
        You may combine the Document with other documents released under this
        License, under the terms defined in section 4 above for modified
        versions, provided that you include in the combination all of the
        Invariant Sections of all of the original documents, unmodified, and
        list them all as Invariant Sections of your combined work in its
        license notice, and that you preserve all their Warranty Disclaimers.
        
        The combined work need only contain one copy of this License, and
        multiple identical Invariant Sections may be replaced with a single
        copy.  If there are multiple Invariant Sections with the same name but
        different contents, make the title of each such section unique by
        adding at the end of it, in parentheses, the name of the original
        author or publisher of that section if known, or else a unique number.
        Make the same adjustment to the section titles in the list of
        Invariant Sections in the license notice of the combined work.
        
        In the combination, you must combine any sections Entitled "History"
        in the various original documents, forming one section Entitled
        "History"; likewise combine any sections Entitled "Acknowledgements",
        and any sections Entitled "Dedications".  You must delete all sections
        Entitled "Endorsements".
        
        
        6. COLLECTIONS OF DOCUMENTS
        
        You may make a collection consisting of the Document and other
        documents released under this License, and replace the individual
        copies of this License in the various documents with a single copy
        that is included in the collection, provided that you follow the rules
        of this License for verbatim copying of each of the documents in all
        other respects.
        
        You may extract a single document from such a collection, and
        distribute it individually under this License, provided you insert a
        copy of this License into the extracted document, and follow this
        License in all other respects regarding verbatim copying of that
        document.
        
        
        7. AGGREGATION WITH INDEPENDENT WORKS
        
        A compilation of the Document or its derivatives with other separate
        and independent documents or works, in or on a volume of a storage or
        distribution medium, is called an "aggregate" if the copyright
        resulting from the compilation is not used to limit the legal rights
        of the compilation's users beyond what the individual works permit.
        When the Document is included in an aggregate, this License does not
        apply to the other works in the aggregate which are not themselves
        derivative works of the Document.
        
        If the Cover Text requirement of section 3 is applicable to these
        copies of the Document, then if the Document is less than one half of
        the entire aggregate, the Document's Cover Texts may be placed on
        covers that bracket the Document within the aggregate, or the
        electronic equivalent of covers if the Document is in electronic form.
        Otherwise they must appear on printed covers that bracket the whole
        aggregate.
        
        
        8. TRANSLATION
        
        Translation is considered a kind of modification, so you may
        distribute translations of the Document under the terms of section 4.
        Replacing Invariant Sections with translations requires special
        permission from their copyright holders, but you may include
        translations of some or all Invariant Sections in addition to the
        original versions of these Invariant Sections.  You may include a
        translation of this License, and all the license notices in the
        Document, and any Warranty Disclaimers, provided that you also include
        the original English version of this License and the original versions
        of those notices and disclaimers.  In case of a disagreement between
        the translation and the original version of this License or a notice
        or disclaimer, the original version will prevail.
        
        If a section in the Document is Entitled "Acknowledgements",
        "Dedications", or "History", the requirement (section 4) to Preserve
        its Title (section 1) will typically require changing the actual
        title.
        
        
        9. TERMINATION
        
        You may not copy, modify, sublicense, or distribute the Document
        except as expressly provided under this License.  Any attempt
        otherwise to copy, modify, sublicense, or distribute it is void, and
        will automatically terminate your rights under this License.
        
        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, receipt of a copy of some or all of the same material does
        not give you any rights to use it.
        
        
        10. FUTURE REVISIONS OF THIS LICENSE
        
        The Free Software Foundation may publish new, revised versions of the
        GNU Free Documentation 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.  See
        http://www.gnu.org/copyleft/.
        
        Each version of the License is given a distinguishing version number.
        If the Document specifies that a particular numbered version of this
        License "or any later version" applies to it, you have the option of
        following the terms and conditions either of that specified version or
        of any later version that has been published (not as a draft) by the
        Free Software Foundation.  If the Document does not specify a version
        number of this License, you may choose any version ever published (not
        as a draft) by the Free Software Foundation.  If the Document
        specifies that a proxy can decide which future versions of this
        License can be used, that proxy's public statement of acceptance of a
        version permanently authorizes you to choose that version for the
        Document.
        
        11. RELICENSING
        
        "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
        World Wide Web server that publishes copyrightable works and also
        provides prominent facilities for anybody to edit those works.  A
        public wiki that anybody can edit is an example of such a server.  A
        "Massive Multiauthor Collaboration" (or "MMC") contained in the site
        means any set of copyrightable works thus published on the MMC site.
        
        "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
        license published by Creative Commons Corporation, a not-for-profit
        corporation with a principal place of business in San Francisco,
        California, as well as future copyleft versions of that license
        published by that same organization.
        
        "Incorporate" means to publish or republish a Document, in whole or in
        part, as part of another Document.
        
        An MMC is "eligible for relicensing" if it is licensed under this
        License, and if all works that were first published under this License
        somewhere other than this MMC, and subsequently incorporated in whole or
        in part into the MMC, (1) had no cover texts or invariant sections, and
        (2) were thus incorporated prior to November 1, 2008.
        
        The operator of an MMC Site may republish an MMC contained in the site
        under CC-BY-SA on the same site at any time before August 1, 2009,
        provided the MMC is eligible for relicensing.

Description
============


CAMB is a cosmology code for calculating cosmological observables, including
CMB, lensing, source count and 21cm angular power spectra, matter power spectra, transfer functions
and background evolution. The code is in Python, with numerical code implemented in fast modern Fortran.

See the `CAMB python example notebook <https://camb.readthedocs.io/en/latest/CAMBdemo.html>`_ for a
quick introduction to how to use the CAMB Python package.

To install the CAMB python package on your computer run::

    pip install camb [--user]

The --user is optional and only required if you don't have write permission to your main python installation.
You will need gfortran 6 or higher installed to compile. Binary files for Windows are also provided, so these are used instead if no
gfortran installation is found on Windows machines.

The python wrapper provides a module called "camb" documented in the Python `CAMB documentation <https://camb.readthedocs.io/en/latest/>`_.
