28*4882a593SmuzhiyunPreamble
29*4882a593Smuzhiyun
30*4882a593SmuzhiyunThe licenses for most software are designed to take away your freedom to
31*4882a593Smuzhiyunshare and change it. By contrast, the GNU General Public Licenses are
32*4882a593Smuzhiyunintended to guarantee your freedom to share and change free software--to
33*4882a593Smuzhiyunmake sure the software is free for all its users.
34*4882a593Smuzhiyun
35*4882a593SmuzhiyunThis license, the Lesser General Public License, applies to some specially
36*4882a593Smuzhiyundesignated software packages--typically libraries--of the Free Software
37*4882a593SmuzhiyunFoundation and other authors who decide to use it. You can use it too, but
38*4882a593Smuzhiyunwe suggest you first think carefully about whether this license or the
39*4882a593Smuzhiyunordinary General Public License is the better strategy to use in any
40*4882a593Smuzhiyunparticular case, based on the explanations below.
41*4882a593Smuzhiyun
42*4882a593SmuzhiyunWhen we speak of free software, we are referring to freedom of use, not
43*4882a593Smuzhiyunprice. Our General Public Licenses are designed to make sure that you have
44*4882a593Smuzhiyunthe freedom to distribute copies of free software (and charge for this
45*4882a593Smuzhiyunservice if you wish); that you receive source code or can get it if you
46*4882a593Smuzhiyunwant it; that you can change the software and use pieces of it in new free
47*4882a593Smuzhiyunprograms; and that you are informed that you can do these things.
48*4882a593Smuzhiyun
49*4882a593SmuzhiyunTo protect your rights, we need to make restrictions that forbid
50*4882a593Smuzhiyundistributors to deny you these rights or to ask you to surrender these
51*4882a593Smuzhiyunrights. These restrictions translate to certain responsibilities for you if
52*4882a593Smuzhiyunyou distribute copies of the library or if you modify it.
53*4882a593Smuzhiyun
54*4882a593SmuzhiyunFor example, if you distribute copies of the library, whether gratis or for
55*4882a593Smuzhiyuna fee, you must give the recipients all the rights that we gave you. You
56*4882a593Smuzhiyunmust make sure that they, too, receive or can get the source code. If you
57*4882a593Smuzhiyunlink other code with the library, you must provide complete object files to
58*4882a593Smuzhiyunthe recipients, so that they can relink them with the library after making
59*4882a593Smuzhiyunchanges to the library and recompiling it. And you must show them these
60*4882a593Smuzhiyunterms so they know their rights.
61*4882a593Smuzhiyun
62*4882a593SmuzhiyunWe protect your rights with a two-step method: (1) we copyright the
63*4882a593Smuzhiyunlibrary, and (2) we offer you this license, which gives you legal
64*4882a593Smuzhiyunpermission to copy, distribute and/or modify the library.
65*4882a593Smuzhiyun
66*4882a593SmuzhiyunTo protect each distributor, we want to make it very clear that there is no
67*4882a593Smuzhiyunwarranty for the free library. Also, if the library is modified by someone
68*4882a593Smuzhiyunelse and passed on, the recipients should know that what they have is not
69*4882a593Smuzhiyunthe original version, so that the original author's reputation will not be
70*4882a593Smuzhiyunaffected by problems that might be introduced by others.
71*4882a593Smuzhiyun
72*4882a593SmuzhiyunFinally, software patents pose a constant threat to the existence of any
73*4882a593Smuzhiyunfree program. We wish to make sure that a company cannot effectively
74*4882a593Smuzhiyunrestrict the users of a free program by obtaining a restrictive license
75*4882a593Smuzhiyunfrom a patent holder. Therefore, we insist that any patent license obtained
76*4882a593Smuzhiyunfor a version of the library must be consistent with the full freedom of
77*4882a593Smuzhiyunuse specified in this license.
78*4882a593Smuzhiyun
79*4882a593SmuzhiyunMost GNU software, including some libraries, is covered by the ordinary GNU
80*4882a593SmuzhiyunGeneral Public License. This license, the GNU Lesser General Public
81*4882a593SmuzhiyunLicense, applies to certain designated libraries, and is quite different
82*4882a593Smuzhiyunfrom the ordinary General Public License. We use this license for certain
83*4882a593Smuzhiyunlibraries in order to permit linking those libraries into non-free
84*4882a593Smuzhiyunprograms.
85*4882a593Smuzhiyun
86*4882a593SmuzhiyunWhen a program is linked with a library, whether statically or using a
87*4882a593Smuzhiyunshared library, the combination of the two is legally speaking a combined
88*4882a593Smuzhiyunwork, a derivative of the original library. The ordinary General Public
89*4882a593SmuzhiyunLicense therefore permits such linking only if the entire combination fits
90*4882a593Smuzhiyunits criteria of freedom. The Lesser General Public License permits more lax
91*4882a593Smuzhiyuncriteria for linking other code with the library.
92*4882a593Smuzhiyun
93*4882a593SmuzhiyunWe call this license the "Lesser" General Public License because it does
94*4882a593SmuzhiyunLess to protect the user's freedom than the ordinary General Public
95*4882a593SmuzhiyunLicense. It also provides other free software developers Less of an
96*4882a593Smuzhiyunadvantage over competing non-free programs. These disadvantages are the
97*4882a593Smuzhiyunreason we use the ordinary General Public License for many
98*4882a593Smuzhiyunlibraries. However, the Lesser license provides advantages in certain
99*4882a593Smuzhiyunspecial circumstances.
100*4882a593Smuzhiyun
101*4882a593SmuzhiyunFor example, on rare occasions, there may be a special need to encourage
102*4882a593Smuzhiyunthe widest possible use of a certain library, so that it becomes a de-facto
103*4882a593Smuzhiyunstandard. To achieve this, non-free programs must be allowed to use the
104*4882a593Smuzhiyunlibrary. A more frequent case is that a free library does the same job as
105*4882a593Smuzhiyunwidely used non-free libraries. In this case, there is little to gain by
106*4882a593Smuzhiyunlimiting the free library to free software only, so we use the Lesser
107*4882a593SmuzhiyunGeneral Public License.
108*4882a593Smuzhiyun
109*4882a593SmuzhiyunIn other cases, permission to use a particular library in non-free programs
110*4882a593Smuzhiyunenables a greater number of people to use a large body of free
111*4882a593Smuzhiyunsoftware. For example, permission to use the GNU C Library in non-free
112*4882a593Smuzhiyunprograms enables many more people to use the whole GNU operating system, as
113*4882a593Smuzhiyunwell as its variant, the GNU/Linux operating system.
114*4882a593Smuzhiyun
115*4882a593SmuzhiyunAlthough the Lesser General Public License is Less protective of the users'
116*4882a593Smuzhiyunfreedom, it does ensure that the user of a program that is linked with the
117*4882a593SmuzhiyunLibrary has the freedom and the wherewithal to run that program using a
118*4882a593Smuzhiyunmodified version of the Library.
119*4882a593Smuzhiyun
120*4882a593SmuzhiyunThe precise terms and conditions for copying, distribution and modification
121*4882a593Smuzhiyunfollow. Pay close attention to the difference between a "work based on the
122*4882a593Smuzhiyunlibrary" and a "work that uses the library". The former contains code
123*4882a593Smuzhiyunderived from the library, whereas the latter must be combined with the
124*4882a593Smuzhiyunlibrary in order to run.
125*4882a593Smuzhiyun
126*4882a593SmuzhiyunTERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
127*4882a593Smuzhiyun
128*4882a593Smuzhiyun0. This License Agreement applies to any software library or other program
129*4882a593Smuzhiyun   which contains a notice placed by the copyright holder or other
130*4882a593Smuzhiyun   authorized party saying it may be distributed under the terms of this
131*4882a593Smuzhiyun   Lesser General Public License (also called "this License"). Each
132*4882a593Smuzhiyun   licensee is addressed as "you".
133*4882a593Smuzhiyun
134*4882a593Smuzhiyun   A "library" means a collection of software functions and/or data
135*4882a593Smuzhiyun   prepared so as to be conveniently linked with application programs
136*4882a593Smuzhiyun   (which use some of those functions and data) to form executables.
137*4882a593Smuzhiyun
138*4882a593Smuzhiyun   The "Library", below, refers to any such software library or work which
139*4882a593Smuzhiyun   has been distributed under these terms. A "work based on the Library"
140*4882a593Smuzhiyun   means either the Library or any derivative work under copyright law:
141*4882a593Smuzhiyun   that is to say, a work containing the Library or a portion of it, either
142*4882a593Smuzhiyun   verbatim or with modifications and/or translated straightforwardly into
143*4882a593Smuzhiyun   another language. (Hereinafter, translation is included without
144*4882a593Smuzhiyun   limitation in the term "modification".)
145*4882a593Smuzhiyun
146*4882a593Smuzhiyun   "Source code" for a work means the preferred form of the work for making
147*4882a593Smuzhiyun   modifications to it. For a library, complete source code means all the
148*4882a593Smuzhiyun   source code for all modules it contains, plus any associated interface
149*4882a593Smuzhiyun   definition files, plus the scripts used to control compilation and
150*4882a593Smuzhiyun   installation of the library.
151*4882a593Smuzhiyun
152*4882a593Smuzhiyun    Activities other than copying, distribution and modification are not
153*4882a593Smuzhiyun    covered by this License; they are outside its scope. The act of running
154*4882a593Smuzhiyun    a program using the Library is not restricted, and output from such a
155*4882a593Smuzhiyun    program is covered only if its contents constitute a work based on the
156*4882a593Smuzhiyun    Library (independent of the use of the Library in a tool for writing
157*4882a593Smuzhiyun    it). Whether that is true depends on what the Library does and what the
158*4882a593Smuzhiyun    program that uses the Library does.
159*4882a593Smuzhiyun
160*4882a593Smuzhiyun1. You may copy and distribute verbatim copies of the Library's complete
161*4882a593Smuzhiyun   source code as you receive it, in any medium, provided that you
162*4882a593Smuzhiyun   conspicuously and appropriately publish on each copy an appropriate
163*4882a593Smuzhiyun   copyright notice and disclaimer of warranty; keep intact all the notices
164*4882a593Smuzhiyun   that refer to this License and to the absence of any warranty; and
165*4882a593Smuzhiyun   distribute a copy of this License along with the Library.
166*4882a593Smuzhiyun
167*4882a593Smuzhiyun   You may charge a fee for the physical act of transferring a copy, and
168*4882a593Smuzhiyun   you may at your option offer warranty protection in exchange for a fee.
169*4882a593Smuzhiyun
170*4882a593Smuzhiyun2. You may modify your copy or copies of the Library or any portion of it,
171*4882a593Smuzhiyun   thus forming a work based on the Library, and copy and distribute such
172*4882a593Smuzhiyun   modifications or work under the terms of Section 1 above, provided that
173*4882a593Smuzhiyun   you also meet all of these conditions:
174*4882a593Smuzhiyun
175*4882a593Smuzhiyun   a) The modified work must itself be a software library.
176*4882a593Smuzhiyun
177*4882a593Smuzhiyun   b) You must cause the files modified to carry prominent notices stating
178*4882a593Smuzhiyun      that you changed the files and the date of any change.
179*4882a593Smuzhiyun
180*4882a593Smuzhiyun   c) You must cause the whole of the work to be licensed at no charge to
181*4882a593Smuzhiyun      all third parties under the terms of this License.
182*4882a593Smuzhiyun
183*4882a593Smuzhiyun   d) If a facility in the modified Library refers to a function or a table
184*4882a593Smuzhiyun      of data to be supplied by an application program that uses the
185*4882a593Smuzhiyun      facility, other than as an argument passed when the facility is
186*4882a593Smuzhiyun      invoked, then you must make a good faith effort to ensure that, in
187*4882a593Smuzhiyun      the event an application does not supply such function or table, the
188*4882a593Smuzhiyun      facility still operates, and performs whatever part of its purpose
189*4882a593Smuzhiyun      remains meaningful.
190*4882a593Smuzhiyun
191*4882a593Smuzhiyun   (For example, a function in a library to compute square roots has a
192*4882a593Smuzhiyun    purpose that is entirely well-defined independent of the
193*4882a593Smuzhiyun    application. Therefore, Subsection 2d requires that any
194*4882a593Smuzhiyun    application-supplied function or table used by this function must be
195*4882a593Smuzhiyun    optional: if the application does not supply it, the square root
196*4882a593Smuzhiyun    function must still compute square roots.)
197*4882a593Smuzhiyun
198*4882a593Smuzhiyun   These requirements apply to the modified work as a whole. If
199*4882a593Smuzhiyun   identifiable sections of that work are not derived from the Library, and
200*4882a593Smuzhiyun   can be reasonably considered independent and separate works in
201*4882a593Smuzhiyun   themselves, then this License, and its terms, do not apply to those
202*4882a593Smuzhiyun   sections when you distribute them as separate works. But when you
203*4882a593Smuzhiyun   distribute the same sections as part of a whole which is a work based on
204*4882a593Smuzhiyun   the Library, the distribution of the whole must be on the terms of this
205*4882a593Smuzhiyun   License, whose permissions for other licensees extend to the entire
206*4882a593Smuzhiyun   whole, and thus to each and every part regardless of who wrote it.
207*4882a593Smuzhiyun
208*4882a593Smuzhiyun   Thus, it is not the intent of this section to claim rights or contest
209*4882a593Smuzhiyun   your rights to work written entirely by you; rather, the intent is to
210*4882a593Smuzhiyun   exercise the right to control the distribution of derivative or
211*4882a593Smuzhiyun   collective works based on the Library.
212*4882a593Smuzhiyun
213*4882a593Smuzhiyun   In addition, mere aggregation of another work not based on the Library
214*4882a593Smuzhiyun   with the Library (or with a work based on the Library) on a volume of a
215*4882a593Smuzhiyun   storage or distribution medium does not bring the other work under the
216*4882a593Smuzhiyun   scope of this License.
217*4882a593Smuzhiyun
218*4882a593Smuzhiyun3. You may opt to apply the terms of the ordinary GNU General Public
219*4882a593Smuzhiyun   License instead of this License to a given copy of the Library. To do
220*4882a593Smuzhiyun   this, you must alter all the notices that refer to this License, so that
221*4882a593Smuzhiyun   they refer to the ordinary GNU General Public License, version 2,
222*4882a593Smuzhiyun   instead of to this License. (If a newer version than version 2 of the
223*4882a593Smuzhiyun   ordinary GNU General Public License has appeared, then you can specify
224*4882a593Smuzhiyun   that version instead if you wish.) Do not make any other change in these
225*4882a593Smuzhiyun   notices.
226*4882a593Smuzhiyun
227*4882a593Smuzhiyun   Once this change is made in a given copy, it is irreversible for that
228*4882a593Smuzhiyun   copy, so the ordinary GNU General Public License applies to all
229*4882a593Smuzhiyun   subsequent copies and derivative works made from that copy.
230*4882a593Smuzhiyun
231*4882a593Smuzhiyun   This option is useful when you wish to copy part of the code of the
232*4882a593Smuzhiyun   Library into a program that is not a library.
233*4882a593Smuzhiyun
234*4882a593Smuzhiyun4. You may copy and distribute the Library (or a portion or derivative of
235*4882a593Smuzhiyun   it, under Section 2) in object code or executable form under the terms
236*4882a593Smuzhiyun   of Sections 1 and 2 above provided that you accompany it with the
237*4882a593Smuzhiyun   complete corresponding machine-readable source code, which must be
238*4882a593Smuzhiyun   distributed under the terms of Sections 1 and 2 above on a medium
239*4882a593Smuzhiyun   customarily used for software interchange.
240*4882a593Smuzhiyun
241*4882a593Smuzhiyun   If distribution of object code is made by offering access to copy from a
242*4882a593Smuzhiyun   designated place, then offering equivalent access to copy the source
243*4882a593Smuzhiyun   code from the same place satisfies the requirement to distribute the
244*4882a593Smuzhiyun   source code, even though third parties are not compelled to copy the
245*4882a593Smuzhiyun   source along with the object code.
246*4882a593Smuzhiyun
247*4882a593Smuzhiyun5. A program that contains no derivative of any portion of the Library, but
248*4882a593Smuzhiyun   is designed to work with the Library by being compiled or linked with
249*4882a593Smuzhiyun   it, is called a "work that uses the Library". Such a work, in isolation,
250*4882a593Smuzhiyun   is not a derivative work of the Library, and therefore falls outside the
251*4882a593Smuzhiyun   scope of this License.
252*4882a593Smuzhiyun
253*4882a593Smuzhiyun   However, linking a "work that uses the Library" with the Library creates
254*4882a593Smuzhiyun   an executable that is a derivative of the Library (because it contains
255*4882a593Smuzhiyun   portions of the Library), rather than a "work that uses the
256*4882a593Smuzhiyun   library". The executable is therefore covered by this License. Section 6
257*4882a593Smuzhiyun   states terms for distribution of such executables.
258*4882a593Smuzhiyun
259*4882a593Smuzhiyun   When a "work that uses the Library" uses material from a header file
260*4882a593Smuzhiyun   that is part of the Library, the object code for the work may be a
261*4882a593Smuzhiyun   derivative work of the Library even though the source code is
262*4882a593Smuzhiyun   not. Whether this is true is especially significant if the work can be
263*4882a593Smuzhiyun   linked without the Library, or if the work is itself a library. The
264*4882a593Smuzhiyun   threshold for this to be true is not precisely defined by law.
265*4882a593Smuzhiyun
266*4882a593Smuzhiyun   If such an object file uses only numerical parameters, data structure
267*4882a593Smuzhiyun   layouts and accessors, and small macros and small inline functions (ten
268*4882a593Smuzhiyun   lines or less in length), then the use of the object file is
269*4882a593Smuzhiyun   unrestricted, regardless of whether it is legally a derivative
270*4882a593Smuzhiyun   work. (Executables containing this object code plus portions of the
271*4882a593Smuzhiyun   Library will still fall under Section 6.)
272*4882a593Smuzhiyun
273*4882a593Smuzhiyun   Otherwise, if the work is a derivative of the Library, you may
274*4882a593Smuzhiyun   distribute the object code for the work under the terms of Section
275*4882a593Smuzhiyun   6. Any executables containing that work also fall under Section 6,
276*4882a593Smuzhiyun   whether or not they are linked directly with the Library itself.
277*4882a593Smuzhiyun
278*4882a593Smuzhiyun6. As an exception to the Sections above, you may also combine or link a
279*4882a593Smuzhiyun   "work that uses the Library" with the Library to produce a work
280*4882a593Smuzhiyun   containing portions of the Library, and distribute that work under terms
281*4882a593Smuzhiyun   of your choice, provided that the terms permit modification of the work
282*4882a593Smuzhiyun   for the customer's own use and reverse engineering for debugging such
283*4882a593Smuzhiyun   modifications.
284*4882a593Smuzhiyun
285*4882a593Smuzhiyun   You must give prominent notice with each copy of the work that the
286*4882a593Smuzhiyun   Library is used in it and that the Library and its use are covered by
287*4882a593Smuzhiyun   this License. You must supply a copy of this License. If the work during
288*4882a593Smuzhiyun   execution displays copyright notices, you must include the copyright
289*4882a593Smuzhiyun   notice for the Library among them, as well as a reference directing the
290*4882a593Smuzhiyun   user to the copy of this License. Also, you must do one of these things:
291*4882a593Smuzhiyun
292*4882a593Smuzhiyun   a) Accompany the work with the complete corresponding machine-readable
293*4882a593Smuzhiyun      source code for the Library including whatever changes were used in
294*4882a593Smuzhiyun      the work (which must be distributed under Sections 1 and 2 above);
295*4882a593Smuzhiyun      and, if the work is an executable linked with the Library, with the
296*4882a593Smuzhiyun      complete machine-readable "work that uses the Library", as object
297*4882a593Smuzhiyun      code and/or source code, so that the user can modify the Library and
298*4882a593Smuzhiyun      then relink to produce a modified executable containing the modified
299*4882a593Smuzhiyun      Library. (It is understood that the user who changes the contents of
300*4882a593Smuzhiyun      definitions files in the Library will not necessarily be able to
301*4882a593Smuzhiyun      recompile the application to use the modified definitions.)
302*4882a593Smuzhiyun
303*4882a593Smuzhiyun   b) Use a suitable shared library mechanism for linking with the
304*4882a593Smuzhiyun      Library. A suitable mechanism is one that (1) uses at run time a copy
305*4882a593Smuzhiyun      of the library already present on the user's computer system, rather
306*4882a593Smuzhiyun      than copying library functions into the executable, and (2) will
307*4882a593Smuzhiyun      operate properly with a modified version of the library, if the user
308*4882a593Smuzhiyun      installs one, as long as the modified version is interface-compatible
309*4882a593Smuzhiyun      with the version that the work was made with.
310*4882a593Smuzhiyun
311*4882a593Smuzhiyun   c) Accompany the work with a written offer, valid for at least three
312*4882a593Smuzhiyun      years, to give the same user the materials specified in Subsection
313*4882a593Smuzhiyun      6a, above, for a charge no more than the cost of performing this
314*4882a593Smuzhiyun      distribution.
315*4882a593Smuzhiyun
316*4882a593Smuzhiyun   d) If distribution of the work is made by offering access to copy from a
317*4882a593Smuzhiyun      designated place, offer equivalent access to copy the above specified
318*4882a593Smuzhiyun      materials from the same place.
319*4882a593Smuzhiyun
320*4882a593Smuzhiyun   e) Verify that the user has already received a copy of these materials
321*4882a593Smuzhiyun      or that you have already sent this user a copy.
322*4882a593Smuzhiyun
323*4882a593Smuzhiyun   For an executable, the required form of the "work that uses the Library"
324*4882a593Smuzhiyun   must include any data and utility programs needed for reproducing the
325*4882a593Smuzhiyun   executable from it. However, as a special exception, the materials to be
326*4882a593Smuzhiyun   distributed need not include anything that is normally distributed (in
327*4882a593Smuzhiyun   either source or binary form) with the major components (compiler,
328*4882a593Smuzhiyun   kernel, and so on) of the operating system on which the executable runs,
329*4882a593Smuzhiyun   unless that component itself accompanies the executable.
330*4882a593Smuzhiyun
331*4882a593Smuzhiyun   It may happen that this requirement contradicts the license restrictions
332*4882a593Smuzhiyun   of other proprietary libraries that do not normally accompany the
333*4882a593Smuzhiyun   operating system. Such a contradiction means you cannot use both them
334*4882a593Smuzhiyun   and the Library together in an executable that you distribute.
335*4882a593Smuzhiyun
336*4882a593Smuzhiyun7. You may place library facilities that are a work based on the Library
337*4882a593Smuzhiyun   side-by-side in a single library together with other library facilities
338*4882a593Smuzhiyun   not covered by this License, and distribute such a combined library,
339*4882a593Smuzhiyun   provided that the separate distribution of the work based on the Library
340*4882a593Smuzhiyun   and of the other library facilities is otherwise permitted, and provided
341*4882a593Smuzhiyun   that you do these two things:
342*4882a593Smuzhiyun
343*4882a593Smuzhiyun   a) Accompany the combined library with a copy of the same work based on
344*4882a593Smuzhiyun      the Library, uncombined with any other library facilities. This must
345*4882a593Smuzhiyun      be distributed under the terms of the Sections above.
346*4882a593Smuzhiyun
347*4882a593Smuzhiyun   b) Give prominent notice with the combined library of the fact that part
348*4882a593Smuzhiyun      of it is a work based on the Library, and explaining where to find
349*4882a593Smuzhiyun      the accompanying uncombined form of the same work.
350*4882a593Smuzhiyun
351*4882a593Smuzhiyun8. You may not copy, modify, sublicense, link with, or distribute the
352*4882a593Smuzhiyun   Library except as expressly provided under this License. Any attempt
353*4882a593Smuzhiyun   otherwise to copy, modify, sublicense, link with, or distribute the
354*4882a593Smuzhiyun   Library is void, and will automatically terminate your rights under this
355*4882a593Smuzhiyun   License. However, parties who have received copies, or rights, from you
356*4882a593Smuzhiyun   under this License will not have their licenses terminated so long as
357*4882a593Smuzhiyun   such parties remain in full compliance.
358*4882a593Smuzhiyun
359*4882a593Smuzhiyun9. You are not required to accept this License, since you have not signed
360*4882a593Smuzhiyun   it. However, nothing else grants you permission to modify or distribute
361*4882a593Smuzhiyun   the Library or its derivative works. These actions are prohibited by law
362*4882a593Smuzhiyun   if you do not accept this License. Therefore, by modifying or
363*4882a593Smuzhiyun   distributing the Library (or any work based on the Library), you
364*4882a593Smuzhiyun   indicate your acceptance of this License to do so, and all its terms and
365*4882a593Smuzhiyun   conditions for copying, distributing or modifying the Library or works
366*4882a593Smuzhiyun   based on it.
367*4882a593Smuzhiyun
368*4882a593Smuzhiyun10. Each time you redistribute the Library (or any work based on the
369*4882a593Smuzhiyun    Library), the recipient automatically receives a license from the
370*4882a593Smuzhiyun    original licensor to copy, distribute, link with or modify the Library
371*4882a593Smuzhiyun    subject to these terms and conditions. You may not impose any further
372*4882a593Smuzhiyun    restrictions on the recipients' exercise of the rights granted
373*4882a593Smuzhiyun    herein. You are not responsible for enforcing compliance by third
374*4882a593Smuzhiyun    parties with this License.
375*4882a593Smuzhiyun
376*4882a593Smuzhiyun11. If, as a consequence of a court judgment or allegation of patent
377*4882a593Smuzhiyun    infringement or for any other reason (not limited to patent issues),
378*4882a593Smuzhiyun    conditions are imposed on you (whether by court order, agreement or
379*4882a593Smuzhiyun    otherwise) that contradict the conditions of this License, they do not
380*4882a593Smuzhiyun    excuse you from the conditions of this License. If you cannot
381*4882a593Smuzhiyun    distribute so as to satisfy simultaneously your obligations under this
382*4882a593Smuzhiyun    License and any other pertinent obligations, then as a consequence you
383*4882a593Smuzhiyun    may not distribute the Library at all. For example, if a patent license
384*4882a593Smuzhiyun    would not permit royalty-free redistribution of the Library by all
385*4882a593Smuzhiyun    those who receive copies directly or indirectly through you, then the
386*4882a593Smuzhiyun    only way you could satisfy both it and this License would be to refrain
387*4882a593Smuzhiyun    entirely from distribution of the Library.
388*4882a593Smuzhiyun
389*4882a593Smuzhiyun    If any portion of this section is held invalid or unenforceable under
390*4882a593Smuzhiyun    any particular circumstance, the balance of the section is intended to
391*4882a593Smuzhiyun    apply, and the section as a whole is intended to apply in other
392*4882a593Smuzhiyun    circumstances.
393*4882a593Smuzhiyun
394*4882a593Smuzhiyun    It is not the purpose of this section to induce you to infringe any
395*4882a593Smuzhiyun    patents or other property right claims or to contest validity of any
396*4882a593Smuzhiyun    such claims; this section has the sole purpose of protecting the
397*4882a593Smuzhiyun    integrity of the free software distribution system which is implemented
398*4882a593Smuzhiyun    by public license practices. Many people have made generous
399*4882a593Smuzhiyun    contributions to the wide range of software distributed through that
400*4882a593Smuzhiyun    system in reliance on consistent application of that system; it is up
401*4882a593Smuzhiyun    to the author/donor to decide if he or she is willing to distribute
402*4882a593Smuzhiyun    software through any other system and a licensee cannot impose that
403*4882a593Smuzhiyun    choice.
404*4882a593Smuzhiyun
405*4882a593Smuzhiyun    This section is intended to make thoroughly clear what is believed to
406*4882a593Smuzhiyun    be a consequence of the rest of this License.
407*4882a593Smuzhiyun
408*4882a593Smuzhiyun12. If the distribution and/or use of the Library is restricted in certain
409*4882a593Smuzhiyun    countries either by patents or by copyrighted interfaces, the original
410*4882a593Smuzhiyun    copyright holder who places the Library under this License may add an
411*4882a593Smuzhiyun    explicit geographical distribution limitation excluding those
412*4882a593Smuzhiyun    countries, so that distribution is permitted only in or among countries
413*4882a593Smuzhiyun    not thus excluded. In such case, this License incorporates the
414*4882a593Smuzhiyun    limitation as if written in the body of this License.
415*4882a593Smuzhiyun
416*4882a593Smuzhiyun13. The Free Software Foundation may publish revised and/or new versions of
417*4882a593Smuzhiyun    the Lesser General Public License from time to time. Such new versions
418*4882a593Smuzhiyun    will be similar in spirit to the present version, but may differ in
419*4882a593Smuzhiyun    detail to address new problems or concerns.
420*4882a593Smuzhiyun
421*4882a593Smuzhiyun    Each version is given a distinguishing version number. If the Library
422*4882a593Smuzhiyun    specifies a version number of this License which applies to it and "any
423*4882a593Smuzhiyun    later version", you have the option of following the terms and
424*4882a593Smuzhiyun    conditions either of that version or of any later version published by
425*4882a593Smuzhiyun    the Free Software Foundation. If the Library does not specify a license
426*4882a593Smuzhiyun    version number, you may choose any version ever published by the Free
427*4882a593Smuzhiyun    Software Foundation.
428*4882a593Smuzhiyun
429*4882a593Smuzhiyun14. If you wish to incorporate parts of the Library into other free
430*4882a593Smuzhiyun    programs whose distribution conditions are incompatible with these,
431*4882a593Smuzhiyun    write to the author to ask for permission. For software which is
432*4882a593Smuzhiyun    copyrighted by the Free Software Foundation, write to the Free Software
433*4882a593Smuzhiyun    Foundation; we sometimes make exceptions for this. Our decision will be
434*4882a593Smuzhiyun    guided by the two goals of preserving the free status of all
435*4882a593Smuzhiyun    derivatives of our free software and of promoting the sharing and reuse
436*4882a593Smuzhiyun    of software generally.
437*4882a593Smuzhiyun
438*4882a593SmuzhiyunNO WARRANTY
439*4882a593Smuzhiyun
440*4882a593Smuzhiyun15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
441*4882a593Smuzhiyun    FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
442*4882a593Smuzhiyun    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
443*4882a593Smuzhiyun    PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
444*4882a593Smuzhiyun    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
445*4882a593Smuzhiyun    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
446*4882a593Smuzhiyun    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH
447*4882a593Smuzhiyun    YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
448*4882a593Smuzhiyun    NECESSARY SERVICING, REPAIR OR CORRECTION.
449*4882a593Smuzhiyun
450*4882a593Smuzhiyun16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
451*4882a593Smuzhiyun    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
452*4882a593Smuzhiyun    REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
453*4882a593Smuzhiyun    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
454*4882a593Smuzhiyun    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
455*4882a593Smuzhiyun    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
456*4882a593Smuzhiyun    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
457*4882a593Smuzhiyun    THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
458*4882a593Smuzhiyun    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

461*4882a593Smuzhiyun
462*4882a593SmuzhiyunHow to Apply These Terms to Your New Libraries
463*4882a593Smuzhiyun
464*4882a593SmuzhiyunIf you develop a new library, and you want it to be of the greatest
465*4882a593Smuzhiyunpossible use to the public, we recommend making it free software that
466*4882a593Smuzhiyuneveryone can redistribute and change. You can do so by permitting
467*4882a593Smuzhiyunredistribution under these terms (or, alternatively, under the terms of the
468*4882a593Smuzhiyunordinary General Public License).
469*4882a593Smuzhiyun
470*4882a593SmuzhiyunTo apply these terms, attach the following notices to the library. It is
471*4882a593Smuzhiyunsafest to attach them to the start of each source file to most effectively
472*4882a593Smuzhiyunconvey the exclusion of warranty; and each file should have at least the
473*4882a593Smuzhiyun"copyright" line and a pointer to where the full notice is found.
474*4882a593Smuzhiyun
475*4882a593Smuzhiyunone line to give the library's name and an idea of what it does.
