277c2aad20Sopenharmony_ci
287c2aad20Sopenharmony_ciPreamble
297c2aad20Sopenharmony_ci
307c2aad20Sopenharmony_ciThe licenses for most software are designed to take away your freedom to
317c2aad20Sopenharmony_cishare and change it. By contrast, the GNU General Public Licenses are
327c2aad20Sopenharmony_ciintended to guarantee your freedom to share and change free software--to
337c2aad20Sopenharmony_cimake sure the software is free for all its users.
347c2aad20Sopenharmony_ci
357c2aad20Sopenharmony_ciThis license, the Lesser General Public License, applies to some specially
367c2aad20Sopenharmony_cidesignated software packages--typically libraries--of the Free Software
377c2aad20Sopenharmony_ciFoundation and other authors who decide to use it. You can use it too, but
387c2aad20Sopenharmony_ciwe suggest you first think carefully about whether this license or the
397c2aad20Sopenharmony_ciordinary General Public License is the better strategy to use in any
407c2aad20Sopenharmony_ciparticular case, based on the explanations below.
417c2aad20Sopenharmony_ci
427c2aad20Sopenharmony_ciWhen we speak of free software, we are referring to freedom of use, not
437c2aad20Sopenharmony_ciprice. Our General Public Licenses are designed to make sure that you have
447c2aad20Sopenharmony_cithe freedom to distribute copies of free software (and charge for this
457c2aad20Sopenharmony_ciservice if you wish); that you receive source code or can get it if you
467c2aad20Sopenharmony_ciwant it; that you can change the software and use pieces of it in new free
477c2aad20Sopenharmony_ciprograms; and that you are informed that you can do these things.
487c2aad20Sopenharmony_ci
497c2aad20Sopenharmony_ciTo protect your rights, we need to make restrictions that forbid
507c2aad20Sopenharmony_cidistributors to deny you these rights or to ask you to surrender these
517c2aad20Sopenharmony_cirights. These restrictions translate to certain responsibilities for you if
527c2aad20Sopenharmony_ciyou distribute copies of the library or if you modify it.
537c2aad20Sopenharmony_ci
547c2aad20Sopenharmony_ciFor example, if you distribute copies of the library, whether gratis or for
557c2aad20Sopenharmony_cia fee, you must give the recipients all the rights that we gave you. You
567c2aad20Sopenharmony_cimust make sure that they, too, receive or can get the source code. If you
577c2aad20Sopenharmony_cilink other code with the library, you must provide complete object files to
587c2aad20Sopenharmony_cithe recipients, so that they can relink them with the library after making
597c2aad20Sopenharmony_cichanges to the library and recompiling it. And you must show them these
607c2aad20Sopenharmony_citerms so they know their rights.
617c2aad20Sopenharmony_ci
627c2aad20Sopenharmony_ciWe protect your rights with a two-step method: (1) we copyright the
637c2aad20Sopenharmony_cilibrary, and (2) we offer you this license, which gives you legal
647c2aad20Sopenharmony_cipermission to copy, distribute and/or modify the library.
657c2aad20Sopenharmony_ci
667c2aad20Sopenharmony_ciTo protect each distributor, we want to make it very clear that there is no
677c2aad20Sopenharmony_ciwarranty for the free library. Also, if the library is modified by someone
687c2aad20Sopenharmony_cielse and passed on, the recipients should know that what they have is not
697c2aad20Sopenharmony_cithe original version, so that the original author's reputation will not be
707c2aad20Sopenharmony_ciaffected by problems that might be introduced by others.
717c2aad20Sopenharmony_ci
727c2aad20Sopenharmony_ciFinally, software patents pose a constant threat to the existence of any
737c2aad20Sopenharmony_cifree program. We wish to make sure that a company cannot effectively
747c2aad20Sopenharmony_cirestrict the users of a free program by obtaining a restrictive license
757c2aad20Sopenharmony_cifrom a patent holder. Therefore, we insist that any patent license obtained
767c2aad20Sopenharmony_cifor a version of the library must be consistent with the full freedom of
777c2aad20Sopenharmony_ciuse specified in this license.
787c2aad20Sopenharmony_ci
797c2aad20Sopenharmony_ciMost GNU software, including some libraries, is covered by the ordinary GNU
807c2aad20Sopenharmony_ciGeneral Public License. This license, the GNU Lesser General Public
817c2aad20Sopenharmony_ciLicense, applies to certain designated libraries, and is quite different
827c2aad20Sopenharmony_cifrom the ordinary General Public License. We use this license for certain
837c2aad20Sopenharmony_cilibraries in order to permit linking those libraries into non-free
847c2aad20Sopenharmony_ciprograms.
857c2aad20Sopenharmony_ci
867c2aad20Sopenharmony_ciWhen a program is linked with a library, whether statically or using a
877c2aad20Sopenharmony_cishared library, the combination of the two is legally speaking a combined
887c2aad20Sopenharmony_ciwork, a derivative of the original library. The ordinary General Public
897c2aad20Sopenharmony_ciLicense therefore permits such linking only if the entire combination fits
907c2aad20Sopenharmony_ciits criteria of freedom. The Lesser General Public License permits more lax
917c2aad20Sopenharmony_cicriteria for linking other code with the library.
927c2aad20Sopenharmony_ci
937c2aad20Sopenharmony_ciWe call this license the "Lesser" General Public License because it does
947c2aad20Sopenharmony_ciLess to protect the user's freedom than the ordinary General Public
957c2aad20Sopenharmony_ciLicense. It also provides other free software developers Less of an
967c2aad20Sopenharmony_ciadvantage over competing non-free programs. These disadvantages are the
977c2aad20Sopenharmony_cireason we use the ordinary General Public License for many
987c2aad20Sopenharmony_cilibraries. However, the Lesser license provides advantages in certain
997c2aad20Sopenharmony_cispecial circumstances.
1007c2aad20Sopenharmony_ci
1017c2aad20Sopenharmony_ciFor example, on rare occasions, there may be a special need to encourage
1027c2aad20Sopenharmony_cithe widest possible use of a certain library, so that it becomes a de-facto
1037c2aad20Sopenharmony_cistandard. To achieve this, non-free programs must be allowed to use the
1047c2aad20Sopenharmony_cilibrary. A more frequent case is that a free library does the same job as
1057c2aad20Sopenharmony_ciwidely used non-free libraries. In this case, there is little to gain by
1067c2aad20Sopenharmony_cilimiting the free library to free software only, so we use the Lesser
1077c2aad20Sopenharmony_ciGeneral Public License.
1087c2aad20Sopenharmony_ci
1097c2aad20Sopenharmony_ciIn other cases, permission to use a particular library in non-free programs
1107c2aad20Sopenharmony_cienables a greater number of people to use a large body of free
1117c2aad20Sopenharmony_cisoftware. For example, permission to use the GNU C Library in non-free
1127c2aad20Sopenharmony_ciprograms enables many more people to use the whole GNU operating system, as
1137c2aad20Sopenharmony_ciwell as its variant, the GNU/Linux operating system.
1147c2aad20Sopenharmony_ci
1157c2aad20Sopenharmony_ciAlthough the Lesser General Public License is Less protective of the users'
1167c2aad20Sopenharmony_cifreedom, it does ensure that the user of a program that is linked with the
1177c2aad20Sopenharmony_ciLibrary has the freedom and the wherewithal to run that program using a
1187c2aad20Sopenharmony_cimodified version of the Library.
1197c2aad20Sopenharmony_ci
1207c2aad20Sopenharmony_ciThe precise terms and conditions for copying, distribution and modification
1217c2aad20Sopenharmony_cifollow. Pay close attention to the difference between a "work based on the
1227c2aad20Sopenharmony_cilibrary" and a "work that uses the library". The former contains code
1237c2aad20Sopenharmony_ciderived from the library, whereas the latter must be combined with the
1247c2aad20Sopenharmony_cilibrary in order to run.
1257c2aad20Sopenharmony_ci
1267c2aad20Sopenharmony_ciTERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
1277c2aad20Sopenharmony_ci
1287c2aad20Sopenharmony_ci0. This License Agreement applies to any software library or other program
1297c2aad20Sopenharmony_ci   which contains a notice placed by the copyright holder or other
1307c2aad20Sopenharmony_ci   authorized party saying it may be distributed under the terms of this
1317c2aad20Sopenharmony_ci   Lesser General Public License (also called "this License"). Each
1327c2aad20Sopenharmony_ci   licensee is addressed as "you".
1337c2aad20Sopenharmony_ci
1347c2aad20Sopenharmony_ci   A "library" means a collection of software functions and/or data
1357c2aad20Sopenharmony_ci   prepared so as to be conveniently linked with application programs
1367c2aad20Sopenharmony_ci   (which use some of those functions and data) to form executables.
1377c2aad20Sopenharmony_ci
1387c2aad20Sopenharmony_ci   The "Library", below, refers to any such software library or work which
1397c2aad20Sopenharmony_ci   has been distributed under these terms. A "work based on the Library"
1407c2aad20Sopenharmony_ci   means either the Library or any derivative work under copyright law:
1417c2aad20Sopenharmony_ci   that is to say, a work containing the Library or a portion of it, either
1427c2aad20Sopenharmony_ci   verbatim or with modifications and/or translated straightforwardly into
1437c2aad20Sopenharmony_ci   another language. (Hereinafter, translation is included without
1447c2aad20Sopenharmony_ci   limitation in the term "modification".)
1457c2aad20Sopenharmony_ci
1467c2aad20Sopenharmony_ci   "Source code" for a work means the preferred form of the work for making
1477c2aad20Sopenharmony_ci   modifications to it. For a library, complete source code means all the
1487c2aad20Sopenharmony_ci   source code for all modules it contains, plus any associated interface
1497c2aad20Sopenharmony_ci   definition files, plus the scripts used to control compilation and
1507c2aad20Sopenharmony_ci   installation of the library.
1517c2aad20Sopenharmony_ci
1527c2aad20Sopenharmony_ci    Activities other than copying, distribution and modification are not
1537c2aad20Sopenharmony_ci    covered by this License; they are outside its scope. The act of running
1547c2aad20Sopenharmony_ci    a program using the Library is not restricted, and output from such a
1557c2aad20Sopenharmony_ci    program is covered only if its contents constitute a work based on the
1567c2aad20Sopenharmony_ci    Library (independent of the use of the Library in a tool for writing
1577c2aad20Sopenharmony_ci    it). Whether that is true depends on what the Library does and what the
1587c2aad20Sopenharmony_ci    program that uses the Library does.
1597c2aad20Sopenharmony_ci
1607c2aad20Sopenharmony_ci1. You may copy and distribute verbatim copies of the Library's complete
1617c2aad20Sopenharmony_ci   source code as you receive it, in any medium, provided that you
1627c2aad20Sopenharmony_ci   conspicuously and appropriately publish on each copy an appropriate
1637c2aad20Sopenharmony_ci   copyright notice and disclaimer of warranty; keep intact all the notices
1647c2aad20Sopenharmony_ci   that refer to this License and to the absence of any warranty; and
1657c2aad20Sopenharmony_ci   distribute a copy of this License along with the Library.
1667c2aad20Sopenharmony_ci
1677c2aad20Sopenharmony_ci   You may charge a fee for the physical act of transferring a copy, and
1687c2aad20Sopenharmony_ci   you may at your option offer warranty protection in exchange for a fee.
1697c2aad20Sopenharmony_ci
1707c2aad20Sopenharmony_ci2. You may modify your copy or copies of the Library or any portion of it,
1717c2aad20Sopenharmony_ci   thus forming a work based on the Library, and copy and distribute such
1727c2aad20Sopenharmony_ci   modifications or work under the terms of Section 1 above, provided that
1737c2aad20Sopenharmony_ci   you also meet all of these conditions:
1747c2aad20Sopenharmony_ci
1757c2aad20Sopenharmony_ci   a) The modified work must itself be a software library.
1767c2aad20Sopenharmony_ci
1777c2aad20Sopenharmony_ci   b) You must cause the files modified to carry prominent notices stating
1787c2aad20Sopenharmony_ci      that you changed the files and the date of any change.
1797c2aad20Sopenharmony_ci
1807c2aad20Sopenharmony_ci   c) You must cause the whole of the work to be licensed at no charge to
1817c2aad20Sopenharmony_ci      all third parties under the terms of this License.
1827c2aad20Sopenharmony_ci
1837c2aad20Sopenharmony_ci   d) If a facility in the modified Library refers to a function or a table
1847c2aad20Sopenharmony_ci      of data to be supplied by an application program that uses the
1857c2aad20Sopenharmony_ci      facility, other than as an argument passed when the facility is
1867c2aad20Sopenharmony_ci      invoked, then you must make a good faith effort to ensure that, in
1877c2aad20Sopenharmony_ci      the event an application does not supply such function or table, the
1887c2aad20Sopenharmony_ci      facility still operates, and performs whatever part of its purpose
1897c2aad20Sopenharmony_ci      remains meaningful.
1907c2aad20Sopenharmony_ci
1917c2aad20Sopenharmony_ci   (For example, a function in a library to compute square roots has a
1927c2aad20Sopenharmony_ci    purpose that is entirely well-defined independent of the
1937c2aad20Sopenharmony_ci    application. Therefore, Subsection 2d requires that any
1947c2aad20Sopenharmony_ci    application-supplied function or table used by this function must be
1957c2aad20Sopenharmony_ci    optional: if the application does not supply it, the square root
1967c2aad20Sopenharmony_ci    function must still compute square roots.)
1977c2aad20Sopenharmony_ci
1987c2aad20Sopenharmony_ci   These requirements apply to the modified work as a whole. If
1997c2aad20Sopenharmony_ci   identifiable sections of that work are not derived from the Library, and
2007c2aad20Sopenharmony_ci   can be reasonably considered independent and separate works in
2017c2aad20Sopenharmony_ci   themselves, then this License, and its terms, do not apply to those
2027c2aad20Sopenharmony_ci   sections when you distribute them as separate works. But when you
2037c2aad20Sopenharmony_ci   distribute the same sections as part of a whole which is a work based on
2047c2aad20Sopenharmony_ci   the Library, the distribution of the whole must be on the terms of this
2057c2aad20Sopenharmony_ci   License, whose permissions for other licensees extend to the entire
2067c2aad20Sopenharmony_ci   whole, and thus to each and every part regardless of who wrote it.
2077c2aad20Sopenharmony_ci
2087c2aad20Sopenharmony_ci   Thus, it is not the intent of this section to claim rights or contest
2097c2aad20Sopenharmony_ci   your rights to work written entirely by you; rather, the intent is to
2107c2aad20Sopenharmony_ci   exercise the right to control the distribution of derivative or
2117c2aad20Sopenharmony_ci   collective works based on the Library.
2127c2aad20Sopenharmony_ci
2137c2aad20Sopenharmony_ci   In addition, mere aggregation of another work not based on the Library
2147c2aad20Sopenharmony_ci   with the Library (or with a work based on the Library) on a volume of a
2157c2aad20Sopenharmony_ci   storage or distribution medium does not bring the other work under the
2167c2aad20Sopenharmony_ci   scope of this License.
2177c2aad20Sopenharmony_ci
2187c2aad20Sopenharmony_ci3. You may opt to apply the terms of the ordinary GNU General Public
2197c2aad20Sopenharmony_ci   License instead of this License to a given copy of the Library. To do
2207c2aad20Sopenharmony_ci   this, you must alter all the notices that refer to this License, so that
2217c2aad20Sopenharmony_ci   they refer to the ordinary GNU General Public License, version 2,
2227c2aad20Sopenharmony_ci   instead of to this License. (If a newer version than version 2 of the
2237c2aad20Sopenharmony_ci   ordinary GNU General Public License has appeared, then you can specify
2247c2aad20Sopenharmony_ci   that version instead if you wish.) Do not make any other change in these
2257c2aad20Sopenharmony_ci   notices.
2267c2aad20Sopenharmony_ci
2277c2aad20Sopenharmony_ci   Once this change is made in a given copy, it is irreversible for that
2287c2aad20Sopenharmony_ci   copy, so the ordinary GNU General Public License applies to all
2297c2aad20Sopenharmony_ci   subsequent copies and derivative works made from that copy.
2307c2aad20Sopenharmony_ci
2317c2aad20Sopenharmony_ci   This option is useful when you wish to copy part of the code of the
2327c2aad20Sopenharmony_ci   Library into a program that is not a library.
2337c2aad20Sopenharmony_ci
2347c2aad20Sopenharmony_ci4. You may copy and distribute the Library (or a portion or derivative of
2357c2aad20Sopenharmony_ci   it, under Section 2) in object code or executable form under the terms
2367c2aad20Sopenharmony_ci   of Sections 1 and 2 above provided that you accompany it with the
2377c2aad20Sopenharmony_ci   complete corresponding machine-readable source code, which must be
2387c2aad20Sopenharmony_ci   distributed under the terms of Sections 1 and 2 above on a medium
2397c2aad20Sopenharmony_ci   customarily used for software interchange.
2407c2aad20Sopenharmony_ci
2417c2aad20Sopenharmony_ci   If distribution of object code is made by offering access to copy from a
2427c2aad20Sopenharmony_ci   designated place, then offering equivalent access to copy the source
2437c2aad20Sopenharmony_ci   code from the same place satisfies the requirement to distribute the
2447c2aad20Sopenharmony_ci   source code, even though third parties are not compelled to copy the
2457c2aad20Sopenharmony_ci   source along with the object code.
2467c2aad20Sopenharmony_ci
2477c2aad20Sopenharmony_ci5. A program that contains no derivative of any portion of the Library, but
2487c2aad20Sopenharmony_ci   is designed to work with the Library by being compiled or linked with
2497c2aad20Sopenharmony_ci   it, is called a "work that uses the Library". Such a work, in isolation,
2507c2aad20Sopenharmony_ci   is not a derivative work of the Library, and therefore falls outside the
2517c2aad20Sopenharmony_ci   scope of this License.
2527c2aad20Sopenharmony_ci
2537c2aad20Sopenharmony_ci   However, linking a "work that uses the Library" with the Library creates
2547c2aad20Sopenharmony_ci   an executable that is a derivative of the Library (because it contains
2557c2aad20Sopenharmony_ci   portions of the Library), rather than a "work that uses the
2567c2aad20Sopenharmony_ci   library". The executable is therefore covered by this License. Section 6
2577c2aad20Sopenharmony_ci   states terms for distribution of such executables.
2587c2aad20Sopenharmony_ci
2597c2aad20Sopenharmony_ci   When a "work that uses the Library" uses material from a header file
2607c2aad20Sopenharmony_ci   that is part of the Library, the object code for the work may be a
2617c2aad20Sopenharmony_ci   derivative work of the Library even though the source code is
2627c2aad20Sopenharmony_ci   not. Whether this is true is especially significant if the work can be
2637c2aad20Sopenharmony_ci   linked without the Library, or if the work is itself a library. The
2647c2aad20Sopenharmony_ci   threshold for this to be true is not precisely defined by law.
2657c2aad20Sopenharmony_ci
2667c2aad20Sopenharmony_ci   If such an object file uses only numerical parameters, data structure
2677c2aad20Sopenharmony_ci   layouts and accessors, and small macros and small inline functions (ten
2687c2aad20Sopenharmony_ci   lines or less in length), then the use of the object file is
2697c2aad20Sopenharmony_ci   unrestricted, regardless of whether it is legally a derivative
2707c2aad20Sopenharmony_ci   work. (Executables containing this object code plus portions of the
2717c2aad20Sopenharmony_ci   Library will still fall under Section 6.)
2727c2aad20Sopenharmony_ci
2737c2aad20Sopenharmony_ci   Otherwise, if the work is a derivative of the Library, you may
2747c2aad20Sopenharmony_ci   distribute the object code for the work under the terms of Section
2757c2aad20Sopenharmony_ci   6. Any executables containing that work also fall under Section 6,
2767c2aad20Sopenharmony_ci   whether or not they are linked directly with the Library itself.
2777c2aad20Sopenharmony_ci
2787c2aad20Sopenharmony_ci6. As an exception to the Sections above, you may also combine or link a
2797c2aad20Sopenharmony_ci   "work that uses the Library" with the Library to produce a work
2807c2aad20Sopenharmony_ci   containing portions of the Library, and distribute that work under terms
2817c2aad20Sopenharmony_ci   of your choice, provided that the terms permit modification of the work
2827c2aad20Sopenharmony_ci   for the customer's own use and reverse engineering for debugging such
2837c2aad20Sopenharmony_ci   modifications.
2847c2aad20Sopenharmony_ci
2857c2aad20Sopenharmony_ci   You must give prominent notice with each copy of the work that the
2867c2aad20Sopenharmony_ci   Library is used in it and that the Library and its use are covered by
2877c2aad20Sopenharmony_ci   this License. You must supply a copy of this License. If the work during
2887c2aad20Sopenharmony_ci   execution displays copyright notices, you must include the copyright
2897c2aad20Sopenharmony_ci   notice for the Library among them, as well as a reference directing the
2907c2aad20Sopenharmony_ci   user to the copy of this License. Also, you must do one of these things:
2917c2aad20Sopenharmony_ci
2927c2aad20Sopenharmony_ci   a) Accompany the work with the complete corresponding machine-readable
2937c2aad20Sopenharmony_ci      source code for the Library including whatever changes were used in
2947c2aad20Sopenharmony_ci      the work (which must be distributed under Sections 1 and 2 above);
2957c2aad20Sopenharmony_ci      and, if the work is an executable linked with the Library, with the
2967c2aad20Sopenharmony_ci      complete machine-readable "work that uses the Library", as object
2977c2aad20Sopenharmony_ci      code and/or source code, so that the user can modify the Library and
2987c2aad20Sopenharmony_ci      then relink to produce a modified executable containing the modified
2997c2aad20Sopenharmony_ci      Library. (It is understood that the user who changes the contents of
3007c2aad20Sopenharmony_ci      definitions files in the Library will not necessarily be able to
3017c2aad20Sopenharmony_ci      recompile the application to use the modified definitions.)
3027c2aad20Sopenharmony_ci
3037c2aad20Sopenharmony_ci   b) Use a suitable shared library mechanism for linking with the
3047c2aad20Sopenharmony_ci      Library. A suitable mechanism is one that (1) uses at run time a copy
3057c2aad20Sopenharmony_ci      of the library already present on the user's computer system, rather
3067c2aad20Sopenharmony_ci      than copying library functions into the executable, and (2) will
3077c2aad20Sopenharmony_ci      operate properly with a modified version of the library, if the user
3087c2aad20Sopenharmony_ci      installs one, as long as the modified version is interface-compatible
3097c2aad20Sopenharmony_ci      with the version that the work was made with.
3107c2aad20Sopenharmony_ci
3117c2aad20Sopenharmony_ci   c) Accompany the work with a written offer, valid for at least three
3127c2aad20Sopenharmony_ci      years, to give the same user the materials specified in Subsection
3137c2aad20Sopenharmony_ci      6a, above, for a charge no more than the cost of performing this
3147c2aad20Sopenharmony_ci      distribution.
3157c2aad20Sopenharmony_ci
3167c2aad20Sopenharmony_ci   d) If distribution of the work is made by offering access to copy from a
3177c2aad20Sopenharmony_ci      designated place, offer equivalent access to copy the above specified
3187c2aad20Sopenharmony_ci      materials from the same place.
3197c2aad20Sopenharmony_ci
3207c2aad20Sopenharmony_ci   e) Verify that the user has already received a copy of these materials
3217c2aad20Sopenharmony_ci      or that you have already sent this user a copy.
3227c2aad20Sopenharmony_ci
3237c2aad20Sopenharmony_ci   For an executable, the required form of the "work that uses the Library"
3247c2aad20Sopenharmony_ci   must include any data and utility programs needed for reproducing the
3257c2aad20Sopenharmony_ci   executable from it. However, as a special exception, the materials to be
3267c2aad20Sopenharmony_ci   distributed need not include anything that is normally distributed (in
3277c2aad20Sopenharmony_ci   either source or binary form) with the major components (compiler,
3287c2aad20Sopenharmony_ci   kernel, and so on) of the operating system on which the executable runs,
3297c2aad20Sopenharmony_ci   unless that component itself accompanies the executable.
3307c2aad20Sopenharmony_ci
3317c2aad20Sopenharmony_ci   It may happen that this requirement contradicts the license restrictions
3327c2aad20Sopenharmony_ci   of other proprietary libraries that do not normally accompany the
3337c2aad20Sopenharmony_ci   operating system. Such a contradiction means you cannot use both them
3347c2aad20Sopenharmony_ci   and the Library together in an executable that you distribute.
3357c2aad20Sopenharmony_ci
3367c2aad20Sopenharmony_ci7. You may place library facilities that are a work based on the Library
3377c2aad20Sopenharmony_ci   side-by-side in a single library together with other library facilities
3387c2aad20Sopenharmony_ci   not covered by this License, and distribute such a combined library,
3397c2aad20Sopenharmony_ci   provided that the separate distribution of the work based on the Library
3407c2aad20Sopenharmony_ci   and of the other library facilities is otherwise permitted, and provided
3417c2aad20Sopenharmony_ci   that you do these two things:
3427c2aad20Sopenharmony_ci
3437c2aad20Sopenharmony_ci   a) Accompany the combined library with a copy of the same work based on
3447c2aad20Sopenharmony_ci      the Library, uncombined with any other library facilities. This must
3457c2aad20Sopenharmony_ci      be distributed under the terms of the Sections above.
3467c2aad20Sopenharmony_ci
3477c2aad20Sopenharmony_ci   b) Give prominent notice with the combined library of the fact that part
3487c2aad20Sopenharmony_ci      of it is a work based on the Library, and explaining where to find
3497c2aad20Sopenharmony_ci      the accompanying uncombined form of the same work.
3507c2aad20Sopenharmony_ci
3517c2aad20Sopenharmony_ci8. You may not copy, modify, sublicense, link with, or distribute the
3527c2aad20Sopenharmony_ci   Library except as expressly provided under this License. Any attempt
3537c2aad20Sopenharmony_ci   otherwise to copy, modify, sublicense, link with, or distribute the
3547c2aad20Sopenharmony_ci   Library is void, and will automatically terminate your rights under this
3557c2aad20Sopenharmony_ci   License. However, parties who have received copies, or rights, from you
3567c2aad20Sopenharmony_ci   under this License will not have their licenses terminated so long as
3577c2aad20Sopenharmony_ci   such parties remain in full compliance.
3587c2aad20Sopenharmony_ci
3597c2aad20Sopenharmony_ci9. You are not required to accept this License, since you have not signed
3607c2aad20Sopenharmony_ci   it. However, nothing else grants you permission to modify or distribute
3617c2aad20Sopenharmony_ci   the Library or its derivative works. These actions are prohibited by law
3627c2aad20Sopenharmony_ci   if you do not accept this License. Therefore, by modifying or
3637c2aad20Sopenharmony_ci   distributing the Library (or any work based on the Library), you
3647c2aad20Sopenharmony_ci   indicate your acceptance of this License to do so, and all its terms and
3657c2aad20Sopenharmony_ci   conditions for copying, distributing or modifying the Library or works
3667c2aad20Sopenharmony_ci   based on it.
3677c2aad20Sopenharmony_ci
3687c2aad20Sopenharmony_ci10. Each time you redistribute the Library (or any work based on the
3697c2aad20Sopenharmony_ci    Library), the recipient automatically receives a license from the
3707c2aad20Sopenharmony_ci    original licensor to copy, distribute, link with or modify the Library
3717c2aad20Sopenharmony_ci    subject to these terms and conditions. You may not impose any further
3727c2aad20Sopenharmony_ci    restrictions on the recipients' exercise of the rights granted
3737c2aad20Sopenharmony_ci    herein. You are not responsible for enforcing compliance by third
3747c2aad20Sopenharmony_ci    parties with this License.
3757c2aad20Sopenharmony_ci
3767c2aad20Sopenharmony_ci11. If, as a consequence of a court judgment or allegation of patent
3777c2aad20Sopenharmony_ci    infringement or for any other reason (not limited to patent issues),
3787c2aad20Sopenharmony_ci    conditions are imposed on you (whether by court order, agreement or
3797c2aad20Sopenharmony_ci    otherwise) that contradict the conditions of this License, they do not
3807c2aad20Sopenharmony_ci    excuse you from the conditions of this License. If you cannot
3817c2aad20Sopenharmony_ci    distribute so as to satisfy simultaneously your obligations under this
3827c2aad20Sopenharmony_ci    License and any other pertinent obligations, then as a consequence you
3837c2aad20Sopenharmony_ci    may not distribute the Library at all. For example, if a patent license
3847c2aad20Sopenharmony_ci    would not permit royalty-free redistribution of the Library by all
3857c2aad20Sopenharmony_ci    those who receive copies directly or indirectly through you, then the
3867c2aad20Sopenharmony_ci    only way you could satisfy both it and this License would be to refrain
3877c2aad20Sopenharmony_ci    entirely from distribution of the Library.
3887c2aad20Sopenharmony_ci
3897c2aad20Sopenharmony_ci    If any portion of this section is held invalid or unenforceable under
3907c2aad20Sopenharmony_ci    any particular circumstance, the balance of the section is intended to
3917c2aad20Sopenharmony_ci    apply, and the section as a whole is intended to apply in other
3927c2aad20Sopenharmony_ci    circumstances.
3937c2aad20Sopenharmony_ci
3947c2aad20Sopenharmony_ci    It is not the purpose of this section to induce you to infringe any
3957c2aad20Sopenharmony_ci    patents or other property right claims or to contest validity of any
3967c2aad20Sopenharmony_ci    such claims; this section has the sole purpose of protecting the
3977c2aad20Sopenharmony_ci    integrity of the free software distribution system which is implemented
3987c2aad20Sopenharmony_ci    by public license practices. Many people have made generous
3997c2aad20Sopenharmony_ci    contributions to the wide range of software distributed through that
4007c2aad20Sopenharmony_ci    system in reliance on consistent application of that system; it is up
4017c2aad20Sopenharmony_ci    to the author/donor to decide if he or she is willing to distribute
4027c2aad20Sopenharmony_ci    software through any other system and a licensee cannot impose that
4037c2aad20Sopenharmony_ci    choice.
4047c2aad20Sopenharmony_ci
4057c2aad20Sopenharmony_ci    This section is intended to make thoroughly clear what is believed to
4067c2aad20Sopenharmony_ci    be a consequence of the rest of this License.
4077c2aad20Sopenharmony_ci
4087c2aad20Sopenharmony_ci12. If the distribution and/or use of the Library is restricted in certain
4097c2aad20Sopenharmony_ci    countries either by patents or by copyrighted interfaces, the original
4107c2aad20Sopenharmony_ci    copyright holder who places the Library under this License may add an
4117c2aad20Sopenharmony_ci    explicit geographical distribution limitation excluding those
4127c2aad20Sopenharmony_ci    countries, so that distribution is permitted only in or among countries
4137c2aad20Sopenharmony_ci    not thus excluded. In such case, this License incorporates the
4147c2aad20Sopenharmony_ci    limitation as if written in the body of this License.
4157c2aad20Sopenharmony_ci
4167c2aad20Sopenharmony_ci13. The Free Software Foundation may publish revised and/or new versions of
4177c2aad20Sopenharmony_ci    the Lesser General Public License from time to time. Such new versions
4187c2aad20Sopenharmony_ci    will be similar in spirit to the present version, but may differ in
4197c2aad20Sopenharmony_ci    detail to address new problems or concerns.
4207c2aad20Sopenharmony_ci
4217c2aad20Sopenharmony_ci    Each version is given a distinguishing version number. If the Library
4227c2aad20Sopenharmony_ci    specifies a version number of this License which applies to it and "any
4237c2aad20Sopenharmony_ci    later version", you have the option of following the terms and
4247c2aad20Sopenharmony_ci    conditions either of that version or of any later version published by
4257c2aad20Sopenharmony_ci    the Free Software Foundation. If the Library does not specify a license
4267c2aad20Sopenharmony_ci    version number, you may choose any version ever published by the Free
4277c2aad20Sopenharmony_ci    Software Foundation.
4287c2aad20Sopenharmony_ci
4297c2aad20Sopenharmony_ci14. If you wish to incorporate parts of the Library into other free
4307c2aad20Sopenharmony_ci    programs whose distribution conditions are incompatible with these,
4317c2aad20Sopenharmony_ci    write to the author to ask for permission. For software which is
4327c2aad20Sopenharmony_ci    copyrighted by the Free Software Foundation, write to the Free Software
4337c2aad20Sopenharmony_ci    Foundation; we sometimes make exceptions for this. Our decision will be
4347c2aad20Sopenharmony_ci    guided by the two goals of preserving the free status of all
4357c2aad20Sopenharmony_ci    derivatives of our free software and of promoting the sharing and reuse
4367c2aad20Sopenharmony_ci    of software generally.
4377c2aad20Sopenharmony_ci
4387c2aad20Sopenharmony_ciNO WARRANTY
4397c2aad20Sopenharmony_ci
4407c2aad20Sopenharmony_ci15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
4417c2aad20Sopenharmony_ci    FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
4427c2aad20Sopenharmony_ci    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
4437c2aad20Sopenharmony_ci    PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
4447c2aad20Sopenharmony_ci    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
4457c2aad20Sopenharmony_ci    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
4467c2aad20Sopenharmony_ci    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH
4477c2aad20Sopenharmony_ci    YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
4487c2aad20Sopenharmony_ci    NECESSARY SERVICING, REPAIR OR CORRECTION.
4497c2aad20Sopenharmony_ci
4507c2aad20Sopenharmony_ci16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
4517c2aad20Sopenharmony_ci    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
4527c2aad20Sopenharmony_ci    REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
4537c2aad20Sopenharmony_ci    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
4547c2aad20Sopenharmony_ci    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
4557c2aad20Sopenharmony_ci    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
4567c2aad20Sopenharmony_ci    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
4577c2aad20Sopenharmony_ci    THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
4587c2aad20Sopenharmony_ci    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

4607c2aad20Sopenharmony_ciEND OF TERMS AND CONDITIONS
4617c2aad20Sopenharmony_ci
4627c2aad20Sopenharmony_ciHow to Apply These Terms to Your New Libraries
4637c2aad20Sopenharmony_ci
4647c2aad20Sopenharmony_ciIf you develop a new library, and you want it to be of the greatest
4657c2aad20Sopenharmony_cipossible use to the public, we recommend making it free software that
4667c2aad20Sopenharmony_cieveryone can redistribute and change. You can do so by permitting
4677c2aad20Sopenharmony_ciredistribution under these terms (or, alternatively, under the terms of the
4687c2aad20Sopenharmony_ciordinary General Public License).
4697c2aad20Sopenharmony_ci
4707c2aad20Sopenharmony_ciTo apply these terms, attach the following notices to the library. It is
4717c2aad20Sopenharmony_cisafest to attach them to the start of each source file to most effectively
4727c2aad20Sopenharmony_ciconvey the exclusion of warranty; and each file should have at least the
4737c2aad20Sopenharmony_ci"copyright" line and a pointer to where the full notice is found.
4747c2aad20Sopenharmony_ci
4757c2aad20Sopenharmony_cione line to give the library's name and an idea of what it does.

4937c2aad20Sopenharmony_ciYou should also get your employer (if you work as a programmer) or your

4957c2aad20Sopenharmony_cinecessary. Here is a sample; alter the names:
