  487. //   .
  488. //                   Preamble
  489. //   .
  490. //     The licenses for most software are designed to take away your
  491. //   freedom to share and change it.  By contrast, the GNU General Public
  492. //   Licenses are intended to guarantee your freedom to share and change
  493. //   free software--to make sure the software is free for all its users.
  494. //   .
  495. //     This license, the Lesser General Public License, applies to some
  496. //   specially designated software packages--typically libraries--of the
  497. //   Free Software Foundation and other authors who decide to use it.  You
  498. //   can use it too, but we suggest you first think carefully about whether
  499. //   this license or the ordinary General Public License is the better
  500. //   strategy to use in any particular case, based on the explanations below.
  501. //   .
  502. //     When we speak of free software, we are referring to freedom of use,
  503. //   not price.  Our General Public Licenses are designed to make sure that
  504. //   you have the freedom to distribute copies of free software (and charge
  505. //   for this service if you wish); that you receive source code or can get
  506. //   it if you want it; that you can change the software and use pieces of
  507. //   it in new free programs; and that you are informed that you can do
  508. //   these things.
  509. //   .
  510. //     To protect your rights, we need to make restrictions that forbid
  511. //   distributors to deny you these rights or to ask you to surrender these
  512. //   rights.  These restrictions translate to certain responsibilities for
  513. //   you if you distribute copies of the library or if you modify it.
  514. //   .
  515. //     For example, if you distribute copies of the library, whether gratis
  516. //   or for a fee, you must give the recipients all the rights that we gave
  517. //   you.  You must make sure that they, too, receive or can get the source
  518. //   code.  If you link other code with the library, you must provide
  519. //   complete object files to the recipients, so that they can relink them
  520. //   with the library after making changes to the library and recompiling
  521. //   it.  And you must show them these terms so they know their rights.
  522. //   .
  523. //     We protect your rights with a two-step method: (1) we copyright the
  524. //   library, and (2) we offer you this license, which gives you legal
  525. //   permission to copy, distribute and/or modify the library.
  526. //   .
  527. //     To protect each distributor, we want to make it very clear that
  528. //   there is no warranty for the free library.  Also, if the library is
  529. //   modified by someone else and passed on, the recipients should know
  530. //   that what they have is not the original version, so that the original
  531. //   author's reputation will not be affected by problems that might be
  532. //   introduced by others.
  533. //   .
  534. //     Finally, software patents pose a constant threat to the existence of
  535. //   any free program.  We wish to make sure that a company cannot
  536. //   effectively restrict the users of a free program by obtaining a
  537. //   restrictive license from a patent holder.  Therefore, we insist that
  538. //   any patent license obtained for a version of the library must be
  539. //   consistent with the full freedom of use specified in this license.
  540. //   .
  541. //     Most GNU software, including some libraries, is covered by the
  542. //   ordinary GNU General Public License.  This license, the GNU Lesser
  543. //   General Public License, applies to certain designated libraries, and
  544. //   is quite different from the ordinary General Public License.  We use
  545. //   this license for certain libraries in order to permit linking those
  546. //   libraries into non-free programs.
  547. //   .
  548. //     When a program is linked with a library, whether statically or using
  549. //   a shared library, the combination of the two is legally speaking a
  550. //   combined work, a derivative of the original library.  The ordinary
  551. //   General Public License therefore permits such linking only if the
  552. //   entire combination fits its criteria of freedom.  The Lesser General
  553. //   Public License permits more lax criteria for linking other code with
  554. //   the library.
  555. //   .
  556. //     We call this license the "Lesser" General Public License because it
  557. //   does Less to protect the user's freedom than the ordinary General
  558. //   Public License.  It also provides other free software developers Less
  559. //   of an advantage over competing non-free programs.  These disadvantages
  560. //   are the reason we use the ordinary General Public License for many
  561. //   libraries.  However, the Lesser license provides advantages in certain
  562. //   special circumstances.
  563. //   .
  564. //     For example, on rare occasions, there may be a special need to
  565. //   encourage the widest possible use of a certain library, so that it becomes
  566. //   a de-facto standard.  To achieve this, non-free programs must be
  567. //   allowed to use the library.  A more frequent case is that a free
  568. //   library does the same job as widely used non-free libraries.  In this
  569. //   case, there is little to gain by limiting the free library to free
  570. //   software only, so we use the Lesser General Public License.
  571. //   .
  572. //     In other cases, permission to use a particular library in non-free
  573. //   programs enables a greater number of people to use a large body of
  574. //   free software.  For example, permission to use the GNU C Library in
  575. //   non-free programs enables many more people to use the whole GNU
  576. //   operating system, as well as its variant, the GNU/Linux operating
  577. //   system.
  578. //   .
  579. //     Although the Lesser General Public License is Less protective of the
  580. //   users' freedom, it does ensure that the user of a program that is
  581. //   linked with the Library has the freedom and the wherewithal to run
  582. //   that program using a modified version of the Library.
  583. //   .
  584. //     The precise terms and conditions for copying, distribution and
  585. //   modification follow.  Pay close attention to the difference between a
  586. //   "work based on the library" and a "work that uses the library".  The
  587. //   former contains code derived from the library, whereas the latter must
  588. //   be combined with the library in order to run.
  589. //   .
  590. //             GNU LESSER GENERAL PUBLIC LICENSE
  591. //      TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
  592. //   .
  593. //     0. This License Agreement applies to any software library or other
  594. //   program which contains a notice placed by the copyright holder or
  595. //   other authorized party saying it may be distributed under the terms of
  596. //   this Lesser General Public License (also called "this License").
  597. //   Each licensee is addressed as "you".
  598. //   .
  599. //     A "library" means a collection of software functions and/or data
  600. //   prepared so as to be conveniently linked with application programs
  601. //   (which use some of those functions and data) to form executables.
  602. //   .
  603. //     The "Library", below, refers to any such software library or work
  604. //   which has been distributed under these terms.  A "work based on the
  605. //   Library" means either the Library or any derivative work under
  606. //   copyright law: that is to say, a work containing the Library or a
  607. //   portion of it, either verbatim or with modifications and/or translated
  608. //   straightforwardly into another language.  (Hereinafter, translation is
  609. //   included without limitation in the term "modification".)
  610. //   .
  611. //     "Source code" for a work means the preferred form of the work for
  612. //   making modifications to it.  For a library, complete source code means
  613. //   all the source code for all modules it contains, plus any associated
  614. //   interface definition files, plus the scripts used to control compilation
  615. //   and installation of the library.
  616. //   .
  617. //     Activities other than copying, distribution and modification are not
  618. //   covered by this License; they are outside its scope.  The act of
  619. //   running a program using the Library is not restricted, and output from
  620. //   such a program is covered only if its contents constitute a work based
  621. //   on the Library (independent of the use of the Library in a tool for
  622. //   writing it).  Whether that is true depends on what the Library does
  623. //   and what the program that uses the Library does.
  624. //     
  625. //     1. You may copy and distribute verbatim copies of the Library's
  626. //   complete source code as you receive it, in any medium, provided that
  627. //   you conspicuously and appropriately publish on each copy an
  628. //   appropriate copyright notice and disclaimer of warranty; keep intact
  629. //   all the notices that refer to this License and to the absence of any
  630. //   warranty; and distribute a copy of this License along with the
  631. //   Library.
  632. //   .
  633. //     You may charge a fee for the physical act of transferring a copy,
  634. //   and you may at your option offer warranty protection in exchange for a
  635. //   fee.
  636. //   .
  637. //     2. You may modify your copy or copies of the Library or any portion
  638. //   of it, thus forming a work based on the Library, and copy and
  639. //   distribute such modifications or work under the terms of Section 1
  640. //   above, provided that you also meet all of these conditions:
  641. //   .
  642. //       a) The modified work must itself be a software library.
  643. //   .
  644. //       b) You must cause the files modified to carry prominent notices
  645. //       stating that you changed the files and the date of any change.
  646. //   .
  647. //       c) You must cause the whole of the work to be licensed at no
  648. //       charge to all third parties under the terms of this License.
  649. //   .
  650. //       d) If a facility in the modified Library refers to a function or a
  651. //       table of data to be supplied by an application program that uses
  652. //       the facility, other than as an argument passed when the facility
  653. //       is invoked, then you must make a good faith effort to ensure that,
  654. //       in the event an application does not supply such function or
  655. //       table, the facility still operates, and performs whatever part of
  656. //       its purpose remains meaningful.
  657. //   .
  658. //       (For example, a function in a library to compute square roots has
  659. //       a purpose that is entirely well-defined independent of the
  660. //       application.  Therefore, Subsection 2d requires that any
  661. //       application-supplied function or table used by this function must
  662. //       be optional: if the application does not supply it, the square
  663. //       root function must still compute square roots.)
  664. //   .
  665. //   These requirements apply to the modified work as a whole.  If
  666. //   identifiable sections of that work are not derived from the Library,
  667. //   and can be reasonably considered independent and separate works in
  668. //   themselves, then this License, and its terms, do not apply to those
  669. //   sections when you distribute them as separate works.  But when you
  670. //   distribute the same sections as part of a whole which is a work based
  671. //   on the Library, the distribution of the whole must be on the terms of
  672. //   this License, whose permissions for other licensees extend to the
  673. //   entire whole, and thus to each and every part regardless of who wrote
  674. //   it.
  675. //   .
  676. //   Thus, it is not the intent of this section to claim rights or contest
  677. //   your rights to work written entirely by you; rather, the intent is to
  678. //   exercise the right to control the distribution of derivative or
  679. //   collective works based on the Library.
  680. //   .
  681. //   In addition, mere aggregation of another work not based on the Library
  682. //   with the Library (or with a work based on the Library) on a volume of
  683. //   a storage or distribution medium does not bring the other work under
  684. //   the scope of this License.
  685. //   .
  686. //     3. You may opt to apply the terms of the ordinary GNU General Public
  687. //   License instead of this License to a given copy of the Library.  To do
  688. //   this, you must alter all the notices that refer to this License, so
  689. //   that they refer to the ordinary GNU General Public License, version 2,
  690. //   instead of to this License.  (If a newer version than version 2 of the
  691. //   ordinary GNU General Public License has appeared, then you can specify
  692. //   that version instead if you wish.)  Do not make any other change in
  693. //   these notices.
  694. //   .
  695. //     Once this change is made in a given copy, it is irreversible for
  696. //   that copy, so the ordinary GNU General Public License applies to all
  697. //   subsequent copies and derivative works made from that copy.
  698. //   .
  699. //     This option is useful when you wish to copy part of the code of
  700. //   the Library into a program that is not a library.
  701. //   .
  702. //     4. You may copy and distribute the Library (or a portion or
  703. //   derivative of it, under Section 2) in object code or executable form
  704. //   under the terms of Sections 1 and 2 above provided that you accompany
  705. //   it with the complete corresponding machine-readable source code, which
  706. //   must be distributed under the terms of Sections 1 and 2 above on a
  707. //   medium customarily used for software interchange.
  708. //   .
  709. //     If distribution of object code is made by offering access to copy
  710. //   from a designated place, then offering equivalent access to copy the
  711. //   source code from the same place satisfies the requirement to
  712. //   distribute the source code, even though third parties are not
  713. //   compelled to copy the source along with the object code.
  714. //   .
  715. //     5. A program that contains no derivative of any portion of the
  716. //   Library, but is designed to work with the Library by being compiled or
  717. //   linked with it, is called a "work that uses the Library".  Such a
  718. //   work, in isolation, is not a derivative work of the Library, and
  719. //   therefore falls outside the scope of this License.
  720. //   .
  721. //     However, linking a "work that uses the Library" with the Library
  722. //   creates an executable that is a derivative of the Library (because it
  723. //   contains portions of the Library), rather than a "work that uses the
  724. //   library".  The executable is therefore covered by this License.
  725. //   Section 6 states terms for distribution of such executables.
  726. //   .
  727. //     When a "work that uses the Library" uses material from a header file
  728. //   that is part of the Library, the object code for the work may be a
  729. //   derivative work of the Library even though the source code is not.
  730. //   Whether this is true is especially significant if the work can be
  731. //   linked without the Library, or if the work is itself a library.  The
  732. //   threshold for this to be true is not precisely defined by law.
  733. //   .
  734. //     If such an object file uses only numerical parameters, data
  735. //   structure layouts and accessors, and small macros and small inline
  736. //   functions (ten lines or less in length), then the use of the object
  737. //   file is unrestricted, regardless of whether it is legally a derivative
  738. //   work.  (Executables containing this object code plus portions of the
  739. //   Library will still fall under Section 6.)
  740. //   .
  741. //     Otherwise, if the work is a derivative of the Library, you may
  742. //   distribute the object code for the work under the terms of Section 6.
  743. //   Any executables containing that work also fall under Section 6,
  744. //   whether or not they are linked directly with the Library itself.
  745. //   .
  746. //     6. As an exception to the Sections above, you may also combine or
  747. //   link a "work that uses the Library" with the Library to produce a
  748. //   work containing portions of the Library, and distribute that work
  749. //   under terms of your choice, provided that the terms permit
  750. //   modification of the work for the customer's own use and reverse
  751. //   engineering for debugging such modifications.
  752. //   .
  753. //     You must give prominent notice with each copy of the work that the
  754. //   Library is used in it and that the Library and its use are covered by
  755. //   this License.  You must supply a copy of this License.  If the work
  756. //   during execution displays copyright notices, you must include the
  757. //   copyright notice for the Library among them, as well as a reference
  758. //   directing the user to the copy of this License.  Also, you must do one
  759. //   of these things:
  760. //   .
  761. //       a) Accompany the work with the complete corresponding
  762. //       machine-readable source code for the Library including whatever
  763. //       changes were used in the work (which must be distributed under
  764. //       Sections 1 and 2 above); and, if the work is an executable linked
  765. //       with the Library, with the complete machine-readable "work that
  766. //       uses the Library", as object code and/or source code, so that the
  767. //       user can modify the Library and then relink to produce a modified
  768. //       executable containing the modified Library.  (It is understood
  769. //       that the user who changes the contents of definitions files in the
  770. //       Library will not necessarily be able to recompile the application
  771. //       to use the modified definitions.)
  772. //   .
  773. //       b) Use a suitable shared library mechanism for linking with the
  774. //       Library.  A suitable mechanism is one that (1) uses at run time a
  775. //       copy of the library already present on the user's computer system,
  776. //       rather than copying library functions into the executable, and (2)
  777. //       will operate properly with a modified version of the library, if
  778. //       the user installs one, as long as the modified version is
  779. //       interface-compatible with the version that the work was made with.
  780. //   .
  781. //       c) Accompany the work with a written offer, valid for at
  782. //       least three years, to give the same user the materials
  783. //       specified in Subsection 6a, above, for a charge no more
  784. //       than the cost of performing this distribution.
  785. //   .
  786. //       d) If distribution of the work is made by offering access to copy
  787. //       from a designated place, offer equivalent access to copy the above
  788. //       specified materials from the same place.
  789. //   .
  790. //       e) Verify that the user has already received a copy of these
  791. //       materials or that you have already sent this user a copy.
  792. //   .
  793. //     For an executable, the required form of the "work that uses the
  794. //   Library" must include any data and utility programs needed for
  795. //   reproducing the executable from it.  However, as a special exception,
  796. //   the materials to be distributed need not include anything that is
  797. //   normally distributed (in either source or binary form) with the major
  798. //   components (compiler, kernel, and so on) of the operating system on
  799. //   which the executable runs, unless that component itself accompanies
  800. //   the executable.
  801. //   .
  802. //     It may happen that this requirement contradicts the license
  803. //   restrictions of other proprietary libraries that do not normally
  804. //   accompany the operating system.  Such a contradiction means you cannot
  805. //   use both them and the Library together in an executable that you
  806. //   distribute.
  807. //   .
  808. //     7. You may place library facilities that are a work based on the
  809. //   Library side-by-side in a single library together with other library
  810. //   facilities not covered by this License, and distribute such a combined
  811. //   library, provided that the separate distribution of the work based on
  812. //   the Library and of the other library facilities is otherwise
  813. //   permitted, and provided that you do these two things:
  814. //   .
  815. //       a) Accompany the combined library with a copy of the same work
  816. //       based on the Library, uncombined with any other library
  817. //       facilities.  This must be distributed under the terms of the
  818. //       Sections above.
  819. //   .
  820. //       b) Give prominent notice with the combined library of the fact
  821. //       that part of it is a work based on the Library, and explaining
  822. //       where to find the accompanying uncombined form of the same work.
  823. //   .
  824. //     8. You may not copy, modify, sublicense, link with, or distribute
  825. //   the Library except as expressly provided under this License.  Any
  826. //   attempt otherwise to copy, modify, sublicense, link with, or
  827. //   distribute the Library is void, and will automatically terminate your
  828. //   rights under this License.  However, parties who have received copies,
  829. //   or rights, from you under this License will not have their licenses
  830. //   terminated so long as such parties remain in full compliance.
  831. //   .
  832. //     9. You are not required to accept this License, since you have not
  833. //   signed it.  However, nothing else grants you permission to modify or
  834. //   distribute the Library or its derivative works.  These actions are
  835. //   prohibited by law if you do not accept this License.  Therefore, by
  836. //   modifying or distributing the Library (or any work based on the
  837. //   Library), you indicate your acceptance of this License to do so, and
  838. //   all its terms and conditions for copying, distributing or modifying
  839. //   the Library or works based on it.
  840. //   .
  841. //     10. Each time you redistribute the Library (or any work based on the
  842. //   Library), the recipient automatically receives a license from the
  843. //   original licensor to copy, distribute, link with or modify the Library
  844. //   subject to these terms and conditions.  You may not impose any further
  845. //   restrictions on the recipients' exercise of the rights granted herein.
  846. //   You are not responsible for enforcing compliance by third parties with
  847. //   this License.
  848. //   .
  849. //     11. If, as a consequence of a court judgment or allegation of patent
  850. //   infringement or for any other reason (not limited to patent issues),
  851. //   conditions are imposed on you (whether by court order, agreement or
  852. //   otherwise) that contradict the conditions of this License, they do not
  853. //   excuse you from the conditions of this License.  If you cannot
  854. //   distribute so as to satisfy simultaneously your obligations under this
  855. //   License and any other pertinent obligations, then as a consequence you
  856. //   may not distribute the Library at all.  For example, if a patent
  857. //   license would not permit royalty-free redistribution of the Library by
  858. //   all those who receive copies directly or indirectly through you, then
  859. //   the only way you could satisfy both it and this License would be to
  860. //   refrain entirely from distribution of the Library.
  861. //   .
  862. //   If any portion of this section is held invalid or unenforceable under any
  863. //   particular circumstance, the balance of the section is intended to apply,
  864. //   and the section as a whole is intended to apply in other circumstances.
  865. //   .
  866. //   It is not the purpose of this section to induce you to infringe any
  867. //   patents or other property right claims or to contest validity of any
  868. //   such claims; this section has the sole purpose of protecting the
  869. //   integrity of the free software distribution system which is
  870. //   implemented by public license practices.  Many people have made
  871. //   generous contributions to the wide range of software distributed
  872. //   through that system in reliance on consistent application of that
  873. //   system; it is up to the author/donor to decide if he or she is willing
  874. //   to distribute software through any other system and a licensee cannot
  875. //   impose that choice.
  876. //   .
  877. //   This section is intended to make thoroughly clear what is believed to
  878. //   be a consequence of the rest of this License.
  879. //   .
  880. //     12. If the distribution and/or use of the Library is restricted in
  881. //   certain countries either by patents or by copyrighted interfaces, the
  882. //   original copyright holder who places the Library under this License may add
  883. //   an explicit geographical distribution limitation excluding those countries,
  884. //   so that distribution is permitted only in or among countries not thus
  885. //   excluded.  In such case, this License incorporates the limitation as if
  886. //   written in the body of this License.
  887. //   .
  888. //     13. The Free Software Foundation may publish revised and/or new
  889. //   versions of the Lesser General Public License from time to time.
  890. //   Such new versions will be similar in spirit to the present version,
  891. //   but may differ in detail to address new problems or concerns.
  892. //   .
  893. //   Each version is given a distinguishing version number.  If the Library
  894. //   specifies a version number of this License which applies to it and
  895. //   "any later version", you have the option of following the terms and
  896. //   conditions either of that version or of any later version published by
  897. //   the Free Software Foundation.  If the Library does not specify a
  898. //   license version number, you may choose any version ever published by
  899. //   the Free Software Foundation.
  900. //   .
  901. //     14. If you wish to incorporate parts of the Library into other free
  902. //   programs whose distribution conditions are incompatible with these,
  903. //   write to the author to ask for permission.  For software which is
  904. //   copyrighted by the Free Software Foundation, write to the Free
  905. //   Software Foundation; we sometimes make exceptions for this.  Our
  906. //   decision will be guided by the two goals of preserving the free status
  907. //   of all derivatives of our free software and of promoting the sharing
  908. //   and reuse of software generally.
  909. //   .
  910. //                   NO WARRANTY
  911. //   .
  912. //     15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
  913. //   WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
  914. //   EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR

  916. //   KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
  917. //   IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
  918. //   PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
  919. //   LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
  920. //   THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  921. //   .
  922. //     16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
  923. //   WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
  924. //   AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
  925. //   FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
  926. //   CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
  927. //   LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING

  931. //   DAMAGES.

  935. //              How to Apply These Terms to Your New Libraries
  936. //   .
  937. //     If you develop a new library, and you want it to be of the greatest
  938. //   possible use to the public, we recommend making it free software that
  939. //   everyone can redistribute and change.  You can do so by permitting
  940. //   redistribution under these terms (or, alternatively, under the terms of the
  941. //   ordinary General Public License).
  942. //   .
  943. //     To apply these terms, attach the following notices to the library.  It is
  944. //   safest to attach them to the start of each source file to most effectively
