-<h2 class="heading"> Preamble </h2>
-
-<p>The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
-</p>
-<p>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&mdash;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.
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-<p>The precise terms and conditions for copying, distribution and
-modification follow.
-</p>
-<a name="SEC71"></a>
-<h2 class="heading"> TERMS AND CONDITIONS </h2>
-
-<ol>
-<li> Definitions.
-
-<p>&ldquo;This License&rdquo; refers to version 3 of the GNU General Public License.
-</p>
-<p>&ldquo;Copyright&rdquo; also means copyright-like laws that apply to other kinds
-of works, such as semiconductor masks.
-</p>
-<p>&ldquo;The Program&rdquo; refers to any copyrightable work licensed under this
-License. Each licensee is addressed as &ldquo;you&rdquo;. &ldquo;Licensees&rdquo; and
-&ldquo;recipients&rdquo; may be individuals or organizations.
-</p>
-<p>To &ldquo;modify&rdquo; 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 &ldquo;modified version&rdquo; of
-the earlier work or a work &ldquo;based on&rdquo; the earlier work.
-</p>
-<p>A &ldquo;covered work&rdquo; means either the unmodified Program or a work based
-on the Program.
-</p>
-<p>To &ldquo;propagate&rdquo; 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.
-</p>
-<p>To &ldquo;convey&rdquo; 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.
-</p>
-<p>An interactive user interface displays &ldquo;Appropriate Legal Notices&rdquo; 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.
-</p>
-</li><li> Source Code.
-
-<p>The &ldquo;source code&rdquo; for a work means the preferred form of the work for
-making modifications to it. &ldquo;Object code&rdquo; means any non-source form
-of a work.
-</p>
-<p>A &ldquo;Standard Interface&rdquo; 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.
-</p>
-<p>The &ldquo;System Libraries&rdquo; 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
-&ldquo;Major Component&rdquo;, 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.
-</p>
-<p>The &ldquo;Corresponding Source&rdquo; 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.
-</p>
-<p>The Corresponding Source need not include anything that users can
-regenerate automatically from other parts of the Corresponding Source.
-</p>
-<p>The Corresponding Source for a work in source code form is that same
-work.
-</p>
-</li><li> Basic Permissions.
-
-<p>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.
-</p>
-<p>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.
-</p>
-<p>Conveying under any other circumstances is permitted solely under the
-conditions stated below. Sublicensing is not allowed; section 10
-makes it unnecessary.
-</p>
-</li><li> Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-<p>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.
-</p>
-<p>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.
-</p>
-</li><li> Conveying Verbatim Copies.
-
-<p>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.
-</p>
-<p>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.
-</p>
-</li><li> Conveying Modified Source Versions.
-
-<p>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:
-</p>
-<ol>
-<li>
-The work must carry prominent notices stating that you modified it,
-and giving a relevant date.
-
-</li><li>
-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 &ldquo;keep intact all
-notices&rdquo;.
-
-</li><li>
-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.
-
-</li><li>
-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.
-</li></ol>
-
-<p>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
-&ldquo;aggregate&rdquo; 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.
-</p>
-</li><li> Conveying Non-Source Forms.
-
-<p>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:
-</p>
-<ol>
-<li>
-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.
-
-</li><li>
-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.
-
-</li><li>
-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.
-
-</li><li>
-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.
-
-</li><li>
-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.
-
-</li></ol>
-
-<p>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.
-</p>
-<p>A &ldquo;User Product&rdquo; is either (1) a &ldquo;consumer product&rdquo;, 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,
-&ldquo;normally used&rdquo; 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.
-</p>
-<p>&ldquo;Installation Information&rdquo; 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.
-</p>
-<p>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).
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-</li><li> Additional Terms.
-
-<p>&ldquo;Additional permissions&rdquo; 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.
-</p>
-<p>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.
-</p>
-<p>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:
-</p>
-<ol>
-<li>
-Disclaiming warranty or limiting liability differently from the terms
-of sections 15 and 16 of this License; or
-
-</li><li>
-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
-
-</li><li>
-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
-
-</li><li>
-Limiting the use for publicity purposes of names of licensors or
-authors of the material; or
-
-</li><li>
-Declining to grant rights under trademark law for use of some trade
-names, trademarks, or service marks; or
-
-</li><li>
-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.
-</li></ol>
-
-<p>All other non-permissive additional terms are considered &ldquo;further
-restrictions&rdquo; 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.
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-</li><li> Termination.
-
-<p>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).
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-</li><li> Acceptance Not Required for Having Copies.
-
-<p>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.
-</p>
-</li><li> Automatic Licensing of Downstream Recipients.
-
-<p>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.
-</p>
-<p>An &ldquo;entity transaction&rdquo; 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.
-</p>
-<p>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.
-</p>
-</li><li> Patents.
-
-<p>A &ldquo;contributor&rdquo; 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 &ldquo;contributor version&rdquo;.
-</p>
-<p>A contributor's &ldquo;essential patent claims&rdquo; 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, &ldquo;control&rdquo; includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-</p>
-<p>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.
-</p>
-<p>In the following three paragraphs, a &ldquo;patent license&rdquo; 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 &ldquo;grant&rdquo; such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-</p>
-<p>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. &ldquo;Knowingly relying&rdquo; 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.
-</p>
-<p>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.
-</p>
-<p>A patent license is &ldquo;discriminatory&rdquo; 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.
-</p>
-<p>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.
-</p>
-</li><li> No Surrender of Others' Freedom.
-
-<p>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.
-</p>
-</li><li> Use with the GNU Affero General Public License.
-
-<p>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.
-</p>
-</li><li> Revised Versions of this License.
-
-<p>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.
-</p>
-<p>Each version is given a distinguishing version number. If the Program
-specifies that a certain numbered version of the GNU General Public
-License &ldquo;or any later version&rdquo; 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.
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-</li><li> Disclaimer of Warranty.
-
-<p>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 &ldquo;AS IS&rdquo; 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.
-</p>
-</li><li> Limitation of Liability.
-
-<p>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.
-</p>
-</li><li> Interpretation of Sections 15 and 16.
-
-<p>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.

-<h2 class="heading"> How to Apply These Terms to Your New Programs </h2>
-
-<p>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.
-</p>
-<p>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 &ldquo;copyright&rdquo; line and a pointer to where the full notice is found.
-</p>
-<table><tr><td>&nbsp;</td><td><pre class="smallexample"><var>one line to give the program's name and a brief idea of what it does.</var>

-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 <a href="http://www.gnu.org/licenses/">http://www.gnu.org/licenses/</a>.
-</pre></td></tr></table>
-
-<p>Also add information on how to contact you by electronic and paper mail.
-</p>
-<p>If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-</p>
-<table><tr><td>&nbsp;</td><td><pre class="smallexample"><var>program</var> Copyright (C) <var>year</var> <var>name of author</var>

-This is free software, and you are welcome to redistribute it
-under certain conditions; type &lsquo;<samp>show c</samp>&rsquo; for details.
-</pre></td></tr></table>
-
-<p>The hypothetical commands &lsquo;<samp>show w</samp>&rsquo; and &lsquo;<samp>show c</samp>&rsquo; 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 &ldquo;about box&rdquo;.
-</p>
-<p>You should also get your employer (if you work as a programmer) or school,
-if any, to sign a &ldquo;copyright disclaimer&rdquo; for the program, if necessary.

-</p>
-<p>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

-
-<p>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.
-</p>
-<ol>
-<li> Additional Definitions.
-
-<p>As used herein, &ldquo;this License&rdquo; refers to version 3 of the GNU Lesser
-General Public License, and the &ldquo;GNU GPL&rdquo; refers to version 3 of the GNU
-General Public License.
-</p>
-<p>&ldquo;The Library&rdquo; refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-</p>
-<p>An &ldquo;Application&rdquo; 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.
-</p>
-<p>A &ldquo;Combined Work&rdquo; 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 &ldquo;Linked
-Version&rdquo;.
-</p>
-<p>The &ldquo;Minimal Corresponding Source&rdquo; 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.
-</p>
-<p>The &ldquo;Corresponding Application Code&rdquo; 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.
-</p>
-</li><li> Exception to Section 3 of the GNU GPL.
-
-<p>You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-</p>
-</li><li> Conveying Modified Versions.
-
-<p>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:
-</p>
-<ol>
-<li>
-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
-
-</li><li>
-under the GNU GPL, with none of the additional permissions of
-this License applicable to that copy.
-</li></ol>
-
-</li><li> Object Code Incorporating Material from Library Header Files.
-
-<p>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:
-</p>
-<ol>
-<li>
-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.
-</li><li>
-Accompany the object code with a copy of the GNU GPL and this license
-document.
-</li></ol>
-
-</li><li> Combined Works.
-
-<p>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:
-</p>
-<ol>
-<li>
-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.
-</li><li>
-Accompany the Combined Work with a copy of the GNU GPL and this license
-document.
-</li><li>
-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.
-</li><li>
-Do one of the following:
-
-<ol>
-<li>
-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.
-</li><li>
-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.
-</li></ol>
-
-</li><li>
-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.)
-</li></ol>
-
-</li><li> Combined Libraries.
-
-<p>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:
-</p>
-<ol>
-<li>
-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.
-</li><li>
-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.
-</li></ol>
-
-</li><li> Revised Versions of the GNU Lesser General Public License.
-
-<p>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.
-</p>
-<p>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 &ldquo;or any later version&rdquo;
-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.
-</p>
-<p>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.

-PREAMBLE
-
-<p>The purpose of this License is to make a manual, textbook, or other
-functional and useful document <em>free</em> 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.
-</p>
-<p>This License is a kind of &ldquo;copyleft&rdquo;, 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.
-</p>
-<p>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.
-</p>

</li><li>
-APPLICABILITY AND DEFINITIONS
-
-<p>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 &ldquo;Document&rdquo;, below,
-refers to any such manual or work. Any member of the public is a
-licensee, and is addressed as &ldquo;you&rdquo;. You accept the license if you
-copy, modify or distribute the work in a way requiring permission
-under copyright law.
-</p>
-<p>A &ldquo;Modified Version&rdquo; 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.
-</p>
-<p>A &ldquo;Secondary Section&rdquo; 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.
-</p>
-<p>The &ldquo;Invariant Sections&rdquo; 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.
-</p>
-<p>The &ldquo;Cover Texts&rdquo; 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.
-</p>
-<p>A &ldquo;Transparent&rdquo; 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 &ldquo;Transparent&rdquo; is called &ldquo;Opaque&rdquo;.
-</p>
-<p>Examples of suitable formats for Transparent copies include plain
-<small>ASCII</small> without markup, Texinfo input format, LaTeX input
-format, <acronym>SGML</acronym> or <acronym>XML</acronym> using a publicly available
-<acronym>DTD</acronym>, and standard-conforming simple <acronym>HTML</acronym>,
-PostScript or <acronym>PDF</acronym> designed for human modification. Examples
-of transparent image formats include <acronym>PNG</acronym>, <acronym>XCF</acronym> and
-<acronym>JPG</acronym>. Opaque formats include proprietary formats that can be
-read and edited only by proprietary word processors, <acronym>SGML</acronym> or
-<acronym>XML</acronym> for which the <acronym>DTD</acronym> and/or processing tools are
-not generally available, and the machine-generated <acronym>HTML</acronym>,
-PostScript or <acronym>PDF</acronym> produced by some word processors for
-output purposes only.
-</p>
-<p>The &ldquo;Title Page&rdquo; 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, &ldquo;Title Page&rdquo; means
-the text near the most prominent appearance of the work's title,
-preceding the beginning of the body of the text.
-</p>
-<p>The &ldquo;publisher&rdquo; means any person or entity that distributes copies
-of the Document to the public.
-</p>
-<p>A section &ldquo;Entitled XYZ&rdquo; 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 &ldquo;Acknowledgements&rdquo;,
-&ldquo;Dedications&rdquo;, &ldquo;Endorsements&rdquo;, or &ldquo;History&rdquo;.) To &ldquo;Preserve the Title&rdquo;
-of such a section when you modify the Document means that it remains a
-section &ldquo;Entitled XYZ&rdquo; according to this definition.
-</p>
-<p>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.

-VERBATIM COPYING
-
-<p>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.
-</p>
-<p>You may also lend copies, under the same conditions stated above, and
-you may publicly display copies.
-</p>
-</li><li>
-COPYING IN QUANTITY
-
-<p>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.
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-<p>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.

-<p>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:
+<p>Unfortunately, this API and its implementation has numerous problems:
</p>
-<ol>
+<ul>
<li>
-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.
-
-</li><li>
-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.
-
-</li><li>
-State on the Title page the name of the publisher of the
-Modified Version, as the publisher.
-
-</li><li>
-Preserve all the copyright notices of the Document.
-
-</li><li>
-Add an appropriate copyright notice for your modifications
-adjacent to the other copyright notices.
-
-</li><li>
-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.
-
-</li><li>
-Preserve in that license notice the full lists of Invariant Sections
-and required Cover Texts given in the Document's license notice.
-
-</li><li>
-Include an unaltered copy of this License.
-
-</li><li>
-Preserve the section Entitled &ldquo;History&rdquo;, 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 &ldquo;History&rdquo; 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.
-
-</li><li>
-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 &ldquo;History&rdquo; 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.
-
-</li><li>
-For any section Entitled &ldquo;Acknowledgements&rdquo; or &ldquo;Dedications&rdquo;, 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.
-
-</li><li>
-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.
-
-</li><li>
-Delete any section Entitled &ldquo;Endorsements&rdquo;. Such a section
-may not be included in the Modified Version.
-
-</li><li>
-Do not retitle any existing section to be Entitled &ldquo;Endorsements&rdquo; or
-to conflict in title with any Invariant Section.
-
-</li><li>
-Preserve any Warranty Disclaimers.
-</li></ol>
-
-<p>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.
-</p>
-<p>You may add a section Entitled &ldquo;Endorsements&rdquo;, provided it contains
-nothing but endorsements of your Modified Version by various
-parties&mdash;for example, statements of peer review or that the text has
-been approved by an organization as the authoritative definition of a
-standard.
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-</li><li>
-COMBINING DOCUMENTS
-
-<p>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.
-</p>
-<p>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.
-</p>
-<p>In the combination, you must combine any sections Entitled &ldquo;History&rdquo;
-in the various original documents, forming one section Entitled
-&ldquo;History&rdquo;; likewise combine any sections Entitled &ldquo;Acknowledgements&rdquo;,
-and any sections Entitled &ldquo;Dedications&rdquo;. You must delete all
-sections Entitled &ldquo;Endorsements.&rdquo;
-</p>
-</li><li>
-COLLECTIONS OF DOCUMENTS
-
-<p>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.
-</p>
-<p>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.
-</p>
-</li><li>
-AGGREGATION WITH INDEPENDENT WORKS
-
-<p>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 &ldquo;aggregate&rdquo; 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.
-</p>
-<p>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.
-</p>
-</li><li>
-TRANSLATION
-
-<p>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.
-</p>
-<p>If a section in the Document is Entitled &ldquo;Acknowledgements&rdquo;,
-&ldquo;Dedications&rdquo;, or &ldquo;History&rdquo;, the requirement (section 4) to Preserve
-its Title (section 1) will typically require changing the actual
-title.
-</p>
-</li><li>
-TERMINATION
-
-<p>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.
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-<p>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.
-</p>
-</li><li>
-FUTURE REVISIONS OF THIS LICENSE
-
-<p>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
-<a href="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</a>.
-</p>
-<p>Each version of the License is given a distinguishing version number.
-If the Document specifies that a particular numbered version of this
-License &ldquo;or any later version&rdquo; 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.
-</p>
-</li><li>
-RELICENSING
-
-<p>&ldquo;Massive Multiauthor Collaboration Site&rdquo; (or &ldquo;MMC Site&rdquo;) 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
-&ldquo;Massive Multiauthor Collaboration&rdquo; (or &ldquo;MMC&rdquo;) contained in the
-site means any set of copyrightable works thus published on the MMC
-site.
-</p>
-<p>&ldquo;CC-BY-SA&rdquo; 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.
-</p>
-<p>&ldquo;Incorporate&rdquo; means to publish or republish a Document, in whole or
-in part, as part of another Document.
-</p>
-<p>An MMC is &ldquo;eligible for relicensing&rdquo; 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.
-</p>
-<p>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.

-
-<p>To use this License in a document you have written, include a copy of

-license notices just after the title page:
-</p>

- with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
- Texts. A copy of the license is included in the section entitled ``GNU
- Free Documentation License''.

+On AIX and Windows platforms, <code>wchar_t</code> is a 16-bit type. This
+means that it can never accommodate an entire Unicode character. Either
+the <code>wchar_t *</code> strings are limited to characters in UCS-2 (the
+&ldquo;Basic Multilingual Plane&rdquo; of Unicode), or &mdash; if <code>wchar_t *</code>
+strings are encoded in UTF-16 &mdash; a <code>wchar_t</code> represents only half
+of a character in the worst case, making the <a href="http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/wctype.h.html"><code>&lt;wctype.h&gt;</code></a> functions
+pointless.
+
+</li><li>
+On Solaris and FreeBSD, the <code>wchar_t</code> encoding is locale dependent
+and undocumented. This means, if you want to know any property of a
+<code>wchar_t</code> character, other than the properties defined by
+<a href="http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/wctype.h.html"><code>&lt;wctype.h&gt;</code></a> &mdash; such as whether it's a dash, currency symbol,
+paragraph separator, or similar &mdash;, you have to convert it to
+<code>char *</code> encoding first, by use of the function <a href="http://pubs.opengroup.org/onlinepubs/9699919799/functions/wctomb.html"><code>wctomb</code></a>.
+
+</li><li>
+When you read a stream of wide characters, through the functions
+<a href="http://pubs.opengroup.org/onlinepubs/9699919799/functions/fgetwc.html"><code>fgetwc</code></a> and <a href="http://pubs.opengroup.org/onlinepubs/9699919799/functions/fgetws.html"><code>fgetws</code></a>, and when the input stream/file is
+not in the expected encoding, you have no way to determine the invalid
+byte sequence and do some corrective action. If you use these
+functions, your program becomes &ldquo;garbage in - more garbage out&rdquo; or
+&ldquo;garbage in - abort&rdquo;.
+</li></ul>
-<p>If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-</p>
-<p>If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License,
-to permit their use in free software.
+<p>As a consequence, it is better to use multibyte strings, as explained in
+the section <a href="libunistring_1.html#SEC6">&lsquo;<samp>char *</samp>&rsquo; strings</a>. Such multibyte strings can bypass
+limitations of the <code>wchar_t</code> type, if you use functions defined in gnulib
+and libunistring for text processing. They can also faithfully transport
+malformed characters that were present in the input, without requiring
+the program to produce garbage or abort.
