Oh, is this still the preferred way in Linux? The + syntax was
deprecated by SPDX [1] in favour of the -only and -or-later variants.
(Also see above in the Linux-syscall-note.)

Or is this the part to make spdxcheck happy?

> +Everyone is permitted to copy and distribute verbatim copies of this
> +license document, but changing it is not allowed.

> +
> +Preamble
> +
> +The licenses for most software are designed to take away your freedom to
> +share and change it. By contrast, the GNU General Public Licenses are
> +intended to guarantee your freedom to share and change free software--to
> +make sure the software is free for all its users.
> +
> +This license, the Lesser General Public License, applies to some specially
> +designated software packages--typically libraries--of the Free Software
> +Foundation and other authors who decide to use it. You can use it too, but
> +we suggest you first think carefully about whether this license or the
> +ordinary General Public License is the better strategy to use in any
> +particular case, based on the explanations below.
> +
> +When we speak of free software, we are referring to freedom of use, 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 this
> +service if you wish); that you receive source code or can get it if you
> +want it; that you can change the software and use pieces of it in new free
> +programs; and that you are informed that you can do these things.
> +
> +To protect your rights, we need to make restrictions that forbid
> +distributors to deny you these rights or to ask you to surrender these
> +rights. These restrictions translate to certain responsibilities for you if
> +you distribute copies of the library or if you modify it.
> +
> +For example, if you distribute copies of the library, whether gratis or for
> +a fee, you must give the recipients all the rights that we gave you. You
> +must make sure that they, too, receive or can get the source code. If you
> +link other code with the library, you must provide complete object files to
> +the recipients, so that they can relink them with the library after making
> +changes to the library and recompiling it. And you must show them these
> +terms so they know their rights.
> +
> +We protect your rights with a two-step method: (1) we copyright the
> +library, and (2) we offer you this license, which gives you legal
> +permission to copy, distribute and/or modify the library.
> +
> +To protect each distributor, we want to make it very clear that there is no
> +warranty for the free library. Also, if the library is modified by someone
> +else and passed on, the recipients should know that what they have is not
> +the original version, so that the original author's reputation will not be
> +affected by problems that might be introduced by others.
> +
> +Finally, software patents pose a constant threat to the existence of any
> +free program. We wish to make sure that a company cannot effectively
> +restrict the users of a free program by obtaining a restrictive license
> +from a patent holder. Therefore, we insist that any patent license obtained
> +for a version of the library must be consistent with the full freedom of
> +use specified in this license.
> +
> +Most GNU software, including some libraries, is covered by the ordinary GNU
> +General Public License. This license, the GNU Lesser General Public
> +License, applies to certain designated libraries, and is quite different
> +from the ordinary General Public License. We use this license for certain
> +libraries in order to permit linking those libraries into non-free
> +programs.
> +
> +When a program is linked with a library, whether statically or using a
> +shared library, the combination of the two is legally speaking a combined
> +work, a derivative of the original library. The ordinary General Public
> +License therefore permits such linking only if the entire combination fits
> +its criteria of freedom. The Lesser General Public License permits more lax
> +criteria for linking other code with the library.
> +
> +We call this license the "Lesser" General Public License because it does
> +Less to protect the user's freedom than the ordinary General Public
> +License. It also provides other free software developers Less of an
> +advantage over competing non-free programs. These disadvantages are the
> +reason we use the ordinary General Public License for many
> +libraries. However, the Lesser license provides advantages in certain
> +special circumstances.
> +
> +For example, on rare occasions, there may be a special need to encourage
> +the widest possible use of a certain library, so that it becomes a de-facto
> +standard. To achieve this, non-free programs must be allowed to use the
> +library. A more frequent case is that a free library does the same job as
> +widely used non-free libraries. In this case, there is little to gain by
> +limiting the free library to free software only, so we use the Lesser

> +The precise terms and conditions for copying, distribution and modification
> +follow. Pay close attention to the difference between a "work based on the

> +
> +   A "library" means a collection of software functions and/or data

> +   (which use some of those functions and data) to form executables.
> +
> +   The "Library", below, refers to any such software library or work which

> +   verbatim or with modifications and/or translated straightforwardly into
> +   another language. (Hereinafter, translation is included without

> +    Activities other than copying, distribution and modification are not
> +    covered by this License; they are outside its scope. The act of running
> +    a program using the Library is not restricted, and output from such a
> +    program is covered only if its contents constitute a work based on the
> +    Library (independent of the use of the Library in a tool for writing
> +    it). Whether that is true depends on what the Library does and what the
> +    program that uses the Library does.
> +
> +1. You may copy and distribute verbatim copies of the Library's complete
> +   source code as you receive it, in any medium, provided that you
> +   conspicuously and appropriately publish on each copy an appropriate
> +   copyright notice and disclaimer of warranty; keep intact all the notices
> +   that refer to this License and to the absence of any warranty; and
> +   distribute a copy of this License along with the Library.
> +
> +   You may charge a fee for the physical act of transferring a copy, and
> +   you may at your option offer warranty protection in exchange for a fee.
> +
> +2. You may modify your copy or copies of the Library or any portion of it,
> +   thus forming a work based on the Library, and copy and distribute such
> +   modifications or work under the terms of Section 1 above, provided that
> +   you also meet all of these conditions:
> +
> +   a) The modified work must itself be a software library.
> +
> +   b) You must cause the files modified to carry prominent notices stating
> +      that you changed the files and the date of any change.
> +
> +   c) You must cause the whole of the work to be licensed at no charge to
> +      all third parties under the terms of this License.
> +
> +   d) If a facility in the modified Library refers to a function or a table
> +      of data to be supplied by an application program that uses the
> +      facility, other than as an argument passed when the facility is
> +      invoked, then you must make a good faith effort to ensure that, in
> +      the event an application does not supply such function or table, the
> +      facility still operates, and performs whatever part of its purpose
> +      remains meaningful.
> +
> +   (For example, a function in a library to compute square roots has a
> +    purpose that is entirely well-defined independent of the
> +    application. Therefore, Subsection 2d requires that any
> +    application-supplied function or table used by this function must be
> +    optional: if the application does not supply it, the square root
> +    function must still compute square roots.)
> +
> +   These requirements apply to the modified work as a whole. If
> +   identifiable sections of that work are not derived from the Library, and
> +   can be reasonably considered independent and separate works in
> +   themselves, then this License, and its terms, do not apply to those
> +   sections when you distribute them as separate works. But when you
> +   distribute the same sections as part of a whole which is a work based on
> +   the Library, the distribution of the whole must be on the terms of this
> +   License, whose permissions for other licensees extend to the entire
> +   whole, and thus to each and every part regardless of who wrote it.
> +
> +   Thus, it is not the intent of this section to claim rights or contest
> +   your rights to work written entirely by you; rather, the intent is to
> +   exercise the right to control the distribution of derivative or
> +   collective works based on the Library.
> +
> +   In addition, mere aggregation of another work not based on the Library
> +   with the Library (or with a work based on the Library) on a volume of a
> +   storage or distribution medium does not bring the other work under the
> +   scope of this License.
> +
> +3. You may opt to apply the terms of the ordinary GNU General Public
> +   License instead of this License to a given copy of the Library. To do
> +   this, you must alter all the notices that refer to this License, so that
> +   they refer to the ordinary GNU General Public License, version 2,
> +   instead of to this License. (If a newer version than version 2 of the
> +   ordinary GNU General Public License has appeared, then you can specify
> +   that version instead if you wish.) Do not make any other change in these
> +   notices.
> +
> +   Once this change is made in a given copy, it is irreversible for that
> +   copy, so the ordinary GNU General Public License applies to all
> +   subsequent copies and derivative works made from that copy.
> +
> +   This option is useful when you wish to copy part of the code of the
> +   Library into a program that is not a library.
> +
> +4. You may copy and distribute the Library (or a portion or derivative of
> +   it, under Section 2) in object code or executable form under the terms
> +   of Sections 1 and 2 above provided that you accompany it with the
> +   complete corresponding machine-readable source code, which must be
> +   distributed under the terms of Sections 1 and 2 above on a medium
> +   customarily used for software interchange.
> +
> +   If distribution of object code is made by offering access to copy from a
> +   designated place, then offering equivalent access to copy the source
> +   code from the same place satisfies the requirement to distribute the
> +   source code, even though third parties are not compelled to copy the
> +   source along with the object code.
> +
> +5. A program that contains no derivative of any portion of the Library, but
> +   is designed to work with the Library by being compiled or linked with
> +   it, is called a "work that uses the Library". Such a work, in isolation,
> +   is not a derivative work of the Library, and therefore falls outside the
> +   scope of this License.
> +
> +   However, linking a "work that uses the Library" with the Library creates
> +   an executable that is a derivative of the Library (because it contains
> +   portions of the Library), rather than a "work that uses the
> +   library". The executable is therefore covered by this License. Section 6
> +   states terms for distribution of such executables.
> +
> +   When a "work that uses the Library" uses material from a header file
> +   that is part of the Library, the object code for the work may be a
> +   derivative work of the Library even though the source code is
> +   not. Whether this is true is especially significant if the work can be
> +   linked without the Library, or if the work is itself a library. The
> +   threshold for this to be true is not precisely defined by law.
> +
> +   If such an object file uses only numerical parameters, data structure
> +   layouts and accessors, and small macros and small inline functions (ten
> +   lines or less in length), then the use of the object file is
> +   unrestricted, regardless of whether it is legally a derivative
> +   work. (Executables containing this object code plus portions of the
> +   Library will still fall under Section 6.)
> +
> +   Otherwise, if the work is a derivative of the Library, you may
> +   distribute the object code for the work under the terms of Section
> +   6. Any executables containing that work also fall under Section 6,
> +   whether or not they are linked directly with the Library itself.
> +
> +6. As an exception to the Sections above, you may also combine or link a
> +   "work that uses the Library" with the Library to produce a work
> +   containing portions of the Library, and distribute that work under terms
> +   of your choice, provided that the terms permit modification of the work
> +   for the customer's own use and reverse engineering for debugging such
> +   modifications.
> +
> +   You must give prominent notice with each copy of the work that the
> +   Library is used in it and that the Library and its use are covered by
> +   this License. You must supply a copy of this License. If the work during
> +   execution displays copyright notices, you must include the copyright
> +   notice for the Library among them, as well as a reference directing the
> +   user to the copy of this License. Also, you must do one of these things:
> +
> +   a) Accompany the work with the complete corresponding machine-readable
> +      source code for the Library including whatever changes were used in
> +      the work (which must be distributed under Sections 1 and 2 above);
> +      and, if the work is an executable linked with the Library, with the
> +      complete machine-readable "work that uses the Library", as object
> +      code and/or source code, so that the user can modify the Library and
> +      then relink to produce a modified executable containing the modified
> +      Library. (It is understood that the user who changes the contents of
> +      definitions files in the Library will not necessarily be able to
> +      recompile the application to use the modified definitions.)
> +
> +   b) Use a suitable shared library mechanism for linking with the
> +      Library. A suitable mechanism is one that (1) uses at run time a copy
> +      of the library already present on the user's computer system, rather
> +      than copying library functions into the executable, and (2) will
> +      operate properly with a modified version of the library, if the user
> +      installs one, as long as the modified version is interface-compatible
> +      with the version that the work was made with.
> +
> +   c) Accompany the work with a written offer, valid for at least three
> +      years, to give the same user the materials specified in Subsection
> +      6a, above, for a charge no more than the cost of performing this
> +      distribution.
> +
> +   d) If distribution of the work is made by offering access to copy from a
> +      designated place, offer equivalent access to copy the above specified
> +      materials from the same place.
> +
> +   e) Verify that the user has already received a copy of these materials
> +      or that you have already sent this user a copy.
> +
> +   For an executable, the required form of the "work that uses the Library"
> +   must include any data and utility programs needed for reproducing the
> +   executable from it. However, as a special exception, the materials to be
> +   distributed need not include anything that is normally distributed (in
> +   either source or binary form) with the major components (compiler,
> +   kernel, and so on) of the operating system on which the executable runs,
> +   unless that component itself accompanies the executable.
> +
> +   It may happen that this requirement contradicts the license restrictions
> +   of other proprietary libraries that do not normally accompany the
> +   operating system. Such a contradiction means you cannot use both them
> +   and the Library together in an executable that you distribute.
> +
> +7. 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
> +   not covered by this License, and distribute such a combined library,
> +   provided that the separate distribution of the work based on the Library
> +   and of the other library facilities is otherwise permitted, and provided
> +   that you do these two things:
> +
> +   a) Accompany the combined library with a copy of the same work based on
> +      the Library, uncombined with any other library facilities. This must
> +      be distributed under the terms of the Sections above.
> +
> +   b) Give prominent notice with the combined library of the fact that part
> +      of it is a work based on the Library, and explaining where to find
> +      the accompanying uncombined form of the same work.
> +
> +8. You may not copy, modify, sublicense, link with, or distribute the
> +   Library except as expressly provided under this License. Any attempt
> +   otherwise to copy, modify, sublicense, link with, or distribute the
> +   Library is void, and will automatically terminate your rights under this
> +   License. However, parties who have received copies, or rights, from you
> +   under this License will not have their licenses terminated so long as
> +   such parties remain in full compliance.
> +
> +9. You are not required to accept this License, since you have not signed
> +   it. However, nothing else grants you permission to modify or distribute
> +   the Library or its derivative works. These actions are prohibited by law
> +   if you do not accept this License. Therefore, by modifying or
> +   distributing the Library (or any work based on the Library), you
> +   indicate your acceptance of this License to do so, and all its terms and
> +   conditions for copying, distributing or modifying the Library or works
> +   based on it.
> +
> +10. Each time you redistribute the Library (or any work based on the
> +    Library), the recipient automatically receives a license from the
> +    original licensor to copy, distribute, link with or modify the Library
> +    subject to these terms and conditions. You may not impose any further
> +    restrictions on the recipients' exercise of the rights granted
> +    herein. You are not responsible for enforcing compliance by third
> +    parties with this License.
> +
> +11. If, as a consequence of a court judgment or allegation of patent
> +    infringement or for any other reason (not limited to patent issues),
> +    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
> +    distribute so as to satisfy simultaneously your obligations under this
> +    License and any other pertinent obligations, then as a consequence you
> +    may not distribute the Library at all. For example, if a patent license
> +    would not permit royalty-free redistribution of the Library by all
> +    those who receive copies directly or indirectly through you, then the
> +    only way you could satisfy both it and this License would be to refrain
> +    entirely from distribution of the Library.
> +
> +    If any portion of this section is held invalid or unenforceable under
> +    any particular circumstance, the balance of the section is intended to
> +    apply, and the section as a whole is intended to apply in other
> +    circumstances.
> +
> +    It is not the purpose of this section to induce you to infringe any
> +    patents or other property right claims or to contest validity of any
> +    such claims; this section has the sole purpose of protecting the
> +    integrity of the free software distribution system which is implemented
> +    by public license practices. Many people have made generous
> +    contributions to the wide range of software distributed through that
> +    system in reliance on consistent application of that system; it is up
> +    to the author/donor to decide if he or she is willing to distribute
> +    software through any other system and a licensee cannot impose that
> +    choice.
> +
> +    This section is intended to make thoroughly clear what is believed to
> +    be a consequence of the rest of this License.
> +
> +12. If the distribution and/or use of the Library is restricted in certain
> +    countries either by patents or by copyrighted interfaces, the original
> +    copyright holder who places the Library under this License may add an
> +    explicit geographical distribution limitation excluding those
> +    countries, so that distribution is permitted only in or among countries
> +    not thus excluded. In such case, this License incorporates the
> +    limitation as if written in the body of this License.
> +
> +13. The Free Software Foundation may publish revised and/or new versions of
> +    the 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
> +    specifies a version number of this License which applies to it and "any
> +    later version", you have the option of following the terms and
> +    conditions either of that version or of any later version published by
> +    the Free Software Foundation. If the Library does not specify a license
> +    version number, you may choose any version ever published by the Free
> +    Software Foundation.
> +
> +14. If you wish to incorporate parts of the Library into other free
> +    programs whose distribution conditions are incompatible with these,
> +    write to the author to ask for permission. For software which is
> +    copyrighted by the Free Software Foundation, write to the Free Software
> +    Foundation; we sometimes make exceptions for this. Our decision will be
> +    guided by the two goals of preserving the free status of all
> +    derivatives of our free software and of promoting the sharing and reuse
> +    of software generally.
> +
> +NO WARRANTY
> +
> +15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
> +    FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
> +    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
> +    PROVIDE THE LIBRARY "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 LIBRARY IS WITH
> +    YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
> +    NECESSARY SERVICING, REPAIR OR CORRECTION.
> +
> +16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
> +    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
> +    REDISTRIBUTE THE LIBRARY 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 LIBRARY
> +    (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR

> +How to Apply These Terms to Your New Libraries
> +
> +If you develop a new library, and you want it to be of the greatest

> -Preamble
> -
> -The licenses for most software are designed to take away your freedom to share
> -and change it. By contrast, the GNU General Public Licenses are intended to
> -guarantee your freedom to share and change free software--to make sure the
> -software is free for all its users.
> -
> -This license, the Lesser General Public License, applies to some specially
> -designated software packages--typically libraries--of the Free Software Foundation
> -and other authors who decide to use it. You can use it too, but we suggest
> -you first think carefully about whether this license or the ordinary General
> -Public License is the better strategy to use in any particular case, based
> -on the explanations below.
> -
> -When we speak of free software, we are referring to freedom of use, 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 this service if you
> -wish); that you receive source code or can get it if you want it; that you
> -can change the software and use pieces of it in new free programs; and that
> -you are informed that you can do these things.
> -
> -To protect your rights, we need to make restrictions that forbid distributors
> -to deny you these rights or to ask you to surrender these rights. These restrictions
> -translate to certain responsibilities for you if you distribute copies of
> -the library or if you modify it.
> -
> -For example, if you distribute copies of the library, whether gratis or for
> -a fee, you must give the recipients all the rights that we gave you. You must
> -make sure that they, too, receive or can get the source code. If you link
> -other code with the library, you must provide complete object files to the
> -recipients, so that they can relink them with the library after making changes
> -to the library and recompiling it. And you must show them these terms so they
> -know their rights.
> -
> -We protect your rights with a two-step method: (1) we copyright the library,
> -and (2) we offer you this license, which gives you legal permission to copy,
> -distribute and/or modify the library.
> -
> -To protect each distributor, we want to make it very clear that there is no
> -warranty for the free library. Also, if the library is modified by someone
> -else and passed on, the recipients should know that what they have is not
> -the original version, so that the original author's reputation will not be
> -affected by problems that might be introduced by others.
> -
> -Finally, software patents pose a constant threat to the existence of any free
> -program. We wish to make sure that a company cannot effectively restrict the
> -users of a free program by obtaining a restrictive license from a patent holder.
> -Therefore, we insist that any patent license obtained for a version of the
> -library must be consistent with the full freedom of use specified in this
> -license.
> -
> -Most GNU software, including some libraries, is covered by the ordinary GNU
> -General Public License. This license, the GNU Lesser General Public License,
> -applies to certain designated libraries, and is quite different from the ordinary
> -General Public License. We use this license for certain libraries in order
> -to permit linking those libraries into non-free programs.
> -
> -When a program is linked with a library, whether statically or using a shared
> -library, the combination of the two is legally speaking a combined work, a
> -derivative of the original library. The ordinary General Public License therefore
> -permits such linking only if the entire combination fits its criteria of freedom.
> -The Lesser General Public License permits more lax criteria for linking other
> -code with the library.
> -
> -We call this license the "Lesser" General Public License because it does Less
> -to protect the user's freedom than the ordinary General Public License. It
> -also provides other free software developers Less of an advantage over competing
> -non-free programs. These disadvantages are the reason we use the ordinary
> -General Public License for many libraries. However, the Lesser license provides
> -advantages in certain special circumstances.
> -
> -For example, on rare occasions, there may be a special need to encourage the
> -widest possible use of a certain library, so that it becomes a de-facto standard.
> -To achieve this, non-free programs must be allowed to use the library. A more
> -frequent case is that a free library does the same job as widely used non-free
> -libraries. In this case, there is little to gain by limiting the free library
> -to free software only, so we use the Lesser General Public License.
> -
> -In other cases, permission to use a particular library in non-free programs
> -enables a greater number of people to use a large body of free software. For
> -example, permission to use the GNU C Library in non-free programs enables
> -many more people to use the whole GNU operating system, as well as its variant,
> -the GNU/Linux operating system.
> -
> -Although the Lesser General Public License is Less protective of the users'
> -freedom, it does ensure that the user of a program that is linked with the
> -Library has the freedom and the wherewithal to run that program using a modified
> -version of the Library.
> -
> -The precise terms and conditions for copying, distribution and modification
> -follow. Pay close attention to the difference between a "work based on the
> -library" and a "work that uses the library". The former contains code derived
> -from the library, whereas the latter must be combined with the library in
> -order to run.
> -
> -TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
> -
> -0. This License Agreement applies to any software library or other program
> -which contains a notice placed by the copyright holder or other authorized
> -party saying it may be distributed under the terms of this Lesser General
> -Public License (also called "this License"). Each licensee is addressed as
> -"you".
> -
> -A "library" means a collection of software functions and/or data prepared
> -so as to be conveniently linked with application programs (which use some
> -of those functions and data) to form executables.
> -
> -The "Library", below, refers to any such software library or work which has
> -been distributed under these terms. A "work based on the Library" means either
> -the Library or any derivative work under copyright law: that is to say, a
> -work containing the Library or a portion of it, either verbatim or with modifications
> -and/or translated straightforwardly into another language. (Hereinafter, translation
> -is included without limitation in the term "modification".)
> -
> -"Source code" for a work means the preferred form of the work for making modifications
> -to it. For a library, complete source code means all the source code for all
> -modules it contains, plus any associated interface definition files, plus
> -the scripts used to control compilation and installation of the library.
> -
> -Activities other than copying, distribution and modification are not covered
> -by this License; they are outside its scope. The act of running a program
> -using the Library is not restricted, and output from such a program is covered
> -only if its contents constitute a work based on the Library (independent of
> -the use of the Library in a tool for writing it). Whether that is true depends

> -      a) The modified work must itself be a software library.
> -
> -b) You must cause the files modified to carry prominent notices stating that
> -you changed the files and the date of any change.
> -
> -c) You must cause the whole of the work to be licensed at no charge to all
> -third parties under the terms of this License.
> -
> -d) If a facility in the modified Library refers to a function or a table of
> -data to be supplied by an application program that uses the facility, other
> -than as an argument passed when the facility is invoked, then you must make
> -a good faith effort to ensure that, in the event an application does not supply
> -such function or table, the facility still operates, and performs whatever
> -part of its purpose remains meaningful.
> -
> -(For example, a function in a library to compute square roots has a purpose
> -that is entirely well-defined independent of the application. Therefore, Subsection
> -2d requires that any application-supplied function or table used by this function
> -must be optional: if the application does not supply it, the square root function
> -must still compute square roots.)
> -
> -These requirements apply to the modified work as a whole. If identifiable
> -sections of that work are not derived from the Library, and can be reasonably
> -considered independent and separate works in themselves, then this License,
> -and its terms, do not apply to those sections when you distribute them as
> -separate works. But when you distribute the same sections as part of a whole
> -which is a work based on the Library, the distribution of the whole must be
> -on the terms of this License, whose permissions for other licensees extend
> -to the entire whole, and thus to each and every part regardless of who wrote
> -it.
> -
> -Thus, it is not the intent of this section to claim rights or contest your
> -rights to work written entirely by you; rather, the intent is to exercise
> -the right to control the distribution of derivative or collective works based
> -on the Library.
> -
> -In addition, mere aggregation of another work not based on the Library with
> -the Library (or with a work based on the Library) on a volume of a storage
> -or distribution medium does not bring the other work under the scope of this
> -License.
> -
> -3. You may opt to apply the terms of the ordinary GNU General Public License
> -instead of this License to a given copy of the Library. To do this, you must
> -alter all the notices that refer to this License, so that they refer to the
> -ordinary GNU General Public License, version 2, instead of to this License.
> -(If a newer version than version 2 of the ordinary GNU General Public License
> -has appeared, then you can specify that version instead if you wish.) Do not
> -make any other change in these notices.
> -
> -Once this change is made in a given copy, it is irreversible for that copy,
> -so the ordinary GNU General Public License applies to all subsequent copies
> -and derivative works made from that copy.
> -
> -This option is useful when you wish to copy part of the code of the Library

> -
> -4. You may copy and distribute the Library (or a portion or derivative of
> -it, under Section 2) in object code or executable form under the terms of
> -Sections 1 and 2 above provided that you accompany it with the complete corresponding
> -machine-readable source code, which must be distributed under the terms of
> -Sections 1 and 2 above on a medium customarily used for software interchange.
> -
> -If distribution of object code is made by offering access to copy from a designated
> -place, then offering equivalent access to copy the source code from the same

> -third parties are not compelled to copy the source along with the object code.
> -
> -5. A program that contains no derivative of any portion of the Library, but
> -is designed to work with the Library by being compiled or linked with it,
> -is called a "work that uses the Library". Such a work, in isolation, is not
> -a derivative work of the Library, and therefore falls outside the scope of
> -this License.
> -
> -However, linking a "work that uses the Library" with the Library creates an
> -executable that is a derivative of the Library (because it contains portions
> -of the Library), rather than a "work that uses the library". The executable
> -is therefore covered by this License. Section 6 states terms for distribution
> -of such executables.
> -
> -When a "work that uses the Library" uses material from a header file that
> -is part of the Library, the object code for the work may be a derivative work
> -of the Library even though the source code is not. Whether this is true is
> -especially significant if the work can be linked without the Library, or if
> -the work is itself a library. The threshold for this to be true is not precisely
> -defined by law.
> -
> -If such an object file uses only numerical parameters, data structure layouts
> -and accessors, and small macros and small inline functions (ten lines or less
> -in length), then the use of the object file is unrestricted, regardless of
> -whether it is legally a derivative work. (Executables containing this object
> -code plus portions of the Library will still fall under Section 6.)
> -
> -Otherwise, if the work is a derivative of the Library, you may distribute
> -the object code for the work under the terms of Section 6. Any executables
> -containing that work also fall under Section 6, whether or not they are linked
> -directly with the Library itself.
> -
> -6. As an exception to the Sections above, you may also combine or link a "work
> -that uses the Library" with the Library to produce a work containing portions
> -of the Library, and distribute that work under terms of your choice, provided
> -that the terms permit modification of the work for the customer's own use
> -and reverse engineering for debugging such modifications.
> -
> -You must give prominent notice with each copy of the work that the Library
> -is used in it and that the Library and its use are covered by this License.
> -You must supply a copy of this License. If the work during execution displays
> -copyright notices, you must include the copyright notice for the Library among
> -them, as well as a reference directing the user to the copy of this License.
> -Also, you must do one of these things:
> -
> -a) Accompany the work with the complete corresponding machine-readable source
> -code for the Library including whatever changes were used in the work (which
> -must be distributed under Sections 1 and 2 above); and, if the work is an
> -executable linked with the Library, with the complete machine-readable "work
> -that uses the Library", as object code and/or source code, so that the user
> -can modify the Library and then relink to produce a modified executable containing
> -the modified Library. (It is understood that the user who changes the contents
> -of definitions files in the Library will not necessarily be able to recompile
> -the application to use the modified definitions.)
> -
> -b) Use a suitable shared library mechanism for linking with the Library. A
> -suitable mechanism is one that (1) uses at run time a copy of the library
> -already present on the user's computer system, rather than copying library
> -functions into the executable, and (2) will operate properly with a modified
> -version of the library, if the user installs one, as long as the modified
> -version is interface-compatible with the version that the work was made with.
> -
> -c) Accompany the work with a written offer, valid for at least three years,
> -to give the same user the materials specified in Subsection 6a, above, for
> -a charge no more than the cost of performing this distribution.
> -
> -d) If distribution of the work is made by offering access to copy from a designated
> -place, offer equivalent access to copy the above specified materials from
> -the same place.
> -
> -e) Verify that the user has already received a copy of these materials or
> -that you have already sent this user a copy.
> -
> -For an executable, the required form of the "work that uses the Library" must
> -include any data and utility programs needed for reproducing the executable
> -from it. However, as a special exception, the materials to be distributed
> -need not include anything that is normally distributed (in either source or
> -binary form) with the major components (compiler, kernel, and so on) of the
> -operating system on which the executable runs, unless that component itself
> -accompanies the executable.
> -
> -It may happen that this requirement contradicts the license restrictions of
> -other proprietary libraries that do not normally accompany the operating system.
> -Such a contradiction means you cannot use both them and the Library together
> -in an executable that you distribute.
> -
> -7. 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 not covered by
> -this License, and distribute such a combined library, provided that the separate
> -distribution of the work based on the Library and of the other library facilities
> -is otherwise permitted, and provided that you do these two things:
> -
> -a) Accompany the combined library with a copy of the same work based on the
> -Library, uncombined with any other library facilities. This must be distributed
> -under the terms of the Sections above.
> -
> -b) Give prominent notice with the combined library of the fact that part of
> -it is a work based on the Library, and explaining where to find the accompanying
> -uncombined form of the same work.
> -
> -8. You may not copy, modify, sublicense, link with, or distribute the Library
> -except as expressly provided under this License. Any attempt otherwise to
> -copy, modify, sublicense, link with, or distribute the Library is void, and
> -will automatically terminate your rights under this License. However, parties
> -who have received copies, or rights, from you under this License will not
> -have their licenses terminated so long as such parties remain in full compliance.
> -
> -9. You are not required to accept this License, since you have not signed
> -it. However, nothing else grants you permission to modify or distribute the
> -Library or its derivative works. These actions are prohibited by law if you
> -do not accept this License. Therefore, by modifying or distributing the Library
> -(or any work based on the Library), you indicate your acceptance of this License
> -to do so, and all its terms and conditions for copying, distributing or modifying
> -the Library or works based on it.
> -
> -10. Each time you redistribute the Library (or any work based on the Library),
> -the recipient automatically receives a license from the original licensor
> -to copy, distribute, link with or modify the Library subject to these terms
> -and conditions. You may not impose any further restrictions on the recipients'
> -exercise of the rights granted herein. You are not responsible for enforcing
> -compliance by third parties with this License.
> -
> -11. If, as a consequence of a court judgment or allegation of patent infringement
> -or for any other reason (not limited to patent issues), 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 distribute so as to satisfy simultaneously your
> -obligations under this License and any other pertinent obligations, then as
> -a consequence you may not distribute the Library at all. For example, if a
> -patent license would not permit royalty-free redistribution of the Library
> -by all those who receive copies directly or indirectly through you, then the
> -only way you could satisfy both it and this License would be to refrain entirely
> -from distribution of the Library.
> -
> -If any portion of this section is held invalid or unenforceable under any
> -particular circumstance, the balance of the section is intended to apply,
> -and the section as a whole is intended to apply in other circumstances.
> -
> -It is not the purpose of this section to induce you to infringe any patents
> -or other property right claims or to contest validity of any such claims;
> -this section has the sole purpose of protecting the integrity of the free
> -software distribution system which is implemented by public license practices.
> -Many people have made generous contributions to the wide range of software
> -distributed through that system in reliance on consistent application of that
> -system; it is up to the author/donor to decide if he or she is willing to
> -distribute software through any other system and a licensee cannot impose
> -that choice.
> -
> -This section is intended to make thoroughly clear what is believed to be a
> -consequence of the rest of this License.
> -
> -12. If the distribution and/or use of the Library is restricted in certain
> -countries either by patents or by copyrighted interfaces, the original copyright
> -holder who places the Library under this License may add an explicit geographical
> -distribution limitation excluding those countries, so that distribution is
> -permitted only in or among countries not thus excluded. In such case, this
> -License incorporates the limitation as if written in the body of this License.
> -
> -13. The Free Software Foundation may publish revised and/or new versions of
> -the 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 specifies
> -a version number of this License which applies to it and "any later version",
> -you have the option of following the terms and conditions either of that version
> -or of any later version published by the Free Software Foundation. If the
> -Library does not specify a license version number, you may choose any version
> -ever published by the Free Software Foundation.
> -
> -14. If you wish to incorporate parts of the Library into other free programs
> -whose distribution conditions are incompatible with these, write to the author
> -to ask for permission. For software which is copyrighted by the Free Software
> -Foundation, write to the Free Software Foundation; we sometimes make exceptions
> -for this. Our decision will be guided by the two goals of preserving the free
> -status of all derivatives of our free software and of promoting the sharing
> -and reuse of software generally.
> -
> -   NO WARRANTY
> -
> -15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
> -THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
> -STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
> -"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 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
> -THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
> -
> -16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
> -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
> -THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
> -GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE

> -How to Apply These Terms to Your New Libraries
> -
> -If you develop a new library, and you want it to be of the greatest possible
> -use to the public, we recommend making it free software that everyone can
> -redistribute and change. You can do so by permitting redistribution under
> -these terms (or, alternatively, under the terms of the ordinary General Public
> -License).
> -
> -To apply these terms, attach the following notices to the library. It is safest
