15*4882a593Smuzhiyun
16*4882a593SmuzhiyunPreamble
17*4882a593Smuzhiyun
18*4882a593SmuzhiyunThe licenses for most software are designed to take away your freedom to share
19*4882a593Smuzhiyunand change it. By contrast, the GNU General Public Licenses are intended to
20*4882a593Smuzhiyunguarantee your freedom to share and change free software--to make sure the
21*4882a593Smuzhiyunsoftware is free for all its users.
22*4882a593Smuzhiyun
23*4882a593SmuzhiyunThis license, the Lesser General Public License, applies to some specially
24*4882a593Smuzhiyundesignated software packages--typically libraries--of the Free Software Foundation
25*4882a593Smuzhiyunand other authors who decide to use it. You can use it too, but we suggest
26*4882a593Smuzhiyunyou first think carefully about whether this license or the ordinary General
27*4882a593SmuzhiyunPublic License is the better strategy to use in any particular case, based
28*4882a593Smuzhiyunon the explanations below.
29*4882a593Smuzhiyun
30*4882a593SmuzhiyunWhen we speak of free software, we are referring to freedom of use, not price.
31*4882a593SmuzhiyunOur General Public Licenses are designed to make sure that you have the freedom
32*4882a593Smuzhiyunto distribute copies of free software (and charge for this service if you
33*4882a593Smuzhiyunwish); that you receive source code or can get it if you want it; that you
34*4882a593Smuzhiyuncan change the software and use pieces of it in new free programs; and that
35*4882a593Smuzhiyunyou are informed that you can do these things.
36*4882a593Smuzhiyun
37*4882a593SmuzhiyunTo protect your rights, we need to make restrictions that forbid distributors
38*4882a593Smuzhiyunto deny you these rights or to ask you to surrender these rights. These restrictions
39*4882a593Smuzhiyuntranslate to certain responsibilities for you if you distribute copies of
40*4882a593Smuzhiyunthe library or if you modify it.
41*4882a593Smuzhiyun
42*4882a593SmuzhiyunFor example, if you distribute copies of the library, whether gratis or for
43*4882a593Smuzhiyuna fee, you must give the recipients all the rights that we gave you. You must
44*4882a593Smuzhiyunmake sure that they, too, receive or can get the source code. If you link
45*4882a593Smuzhiyunother code with the library, you must provide complete object files to the
46*4882a593Smuzhiyunrecipients, so that they can relink them with the library after making changes
47*4882a593Smuzhiyunto the library and recompiling it. And you must show them these terms so they
48*4882a593Smuzhiyunknow their rights.
49*4882a593Smuzhiyun
50*4882a593SmuzhiyunWe protect your rights with a two-step method: (1) we copyright the library,
51*4882a593Smuzhiyunand (2) we offer you this license, which gives you legal permission to copy,
52*4882a593Smuzhiyundistribute and/or modify the library.
53*4882a593Smuzhiyun
54*4882a593SmuzhiyunTo protect each distributor, we want to make it very clear that there is no
55*4882a593Smuzhiyunwarranty for the free library. Also, if the library is modified by someone
56*4882a593Smuzhiyunelse and passed on, the recipients should know that what they have is not
57*4882a593Smuzhiyunthe original version, so that the original author's reputation will not be
58*4882a593Smuzhiyunaffected by problems that might be introduced by others.
59*4882a593Smuzhiyun
60*4882a593SmuzhiyunFinally, software patents pose a constant threat to the existence of any free
61*4882a593Smuzhiyunprogram. We wish to make sure that a company cannot effectively restrict the
62*4882a593Smuzhiyunusers of a free program by obtaining a restrictive license from a patent holder.
63*4882a593SmuzhiyunTherefore, we insist that any patent license obtained for a version of the
64*4882a593Smuzhiyunlibrary must be consistent with the full freedom of use specified in this
65*4882a593Smuzhiyunlicense.
66*4882a593Smuzhiyun
67*4882a593SmuzhiyunMost GNU software, including some libraries, is covered by the ordinary GNU
68*4882a593SmuzhiyunGeneral Public License. This license, the GNU Lesser General Public License,
69*4882a593Smuzhiyunapplies to certain designated libraries, and is quite different from the ordinary
70*4882a593SmuzhiyunGeneral Public License. We use this license for certain libraries in order
71*4882a593Smuzhiyunto permit linking those libraries into non-free programs.
72*4882a593Smuzhiyun
73*4882a593SmuzhiyunWhen a program is linked with a library, whether statically or using a shared
74*4882a593Smuzhiyunlibrary, the combination of the two is legally speaking a combined work, a
75*4882a593Smuzhiyunderivative of the original library. The ordinary General Public License therefore
76*4882a593Smuzhiyunpermits such linking only if the entire combination fits its criteria of freedom.
77*4882a593SmuzhiyunThe Lesser General Public License permits more lax criteria for linking other
78*4882a593Smuzhiyuncode with the library.
79*4882a593Smuzhiyun
80*4882a593SmuzhiyunWe call this license the "Lesser" General Public License because it does Less
81*4882a593Smuzhiyunto protect the user's freedom than the ordinary General Public License. It
82*4882a593Smuzhiyunalso provides other free software developers Less of an advantage over competing
83*4882a593Smuzhiyunnon-free programs. These disadvantages are the reason we use the ordinary
84*4882a593SmuzhiyunGeneral Public License for many libraries. However, the Lesser license provides
85*4882a593Smuzhiyunadvantages in certain special circumstances.
86*4882a593Smuzhiyun
87*4882a593SmuzhiyunFor example, on rare occasions, there may be a special need to encourage the
88*4882a593Smuzhiyunwidest possible use of a certain library, so that it becomes a de-facto standard.
89*4882a593SmuzhiyunTo achieve this, non-free programs must be allowed to use the library. A more
90*4882a593Smuzhiyunfrequent case is that a free library does the same job as widely used non-free
91*4882a593Smuzhiyunlibraries. In this case, there is little to gain by limiting the free library
92*4882a593Smuzhiyunto free software only, so we use the Lesser General Public License.
93*4882a593Smuzhiyun
94*4882a593SmuzhiyunIn other cases, permission to use a particular library in non-free programs
95*4882a593Smuzhiyunenables a greater number of people to use a large body of free software. For
96*4882a593Smuzhiyunexample, permission to use the GNU C Library in non-free programs enables
97*4882a593Smuzhiyunmany more people to use the whole GNU operating system, as well as its variant,
98*4882a593Smuzhiyunthe GNU/Linux operating system.
99*4882a593Smuzhiyun
100*4882a593SmuzhiyunAlthough the Lesser General Public License is Less protective of the users'
101*4882a593Smuzhiyunfreedom, it does ensure that the user of a program that is linked with the
102*4882a593SmuzhiyunLibrary has the freedom and the wherewithal to run that program using a modified
103*4882a593Smuzhiyunversion of the Library.
104*4882a593Smuzhiyun
105*4882a593SmuzhiyunThe precise terms and conditions for copying, distribution and modification
106*4882a593Smuzhiyunfollow. Pay close attention to the difference between a "work based on the
107*4882a593Smuzhiyunlibrary" and a "work that uses the library". The former contains code derived
108*4882a593Smuzhiyunfrom the library, whereas the latter must be combined with the library in
109*4882a593Smuzhiyunorder to run.
110*4882a593Smuzhiyun
111*4882a593SmuzhiyunTERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
112*4882a593Smuzhiyun
113*4882a593Smuzhiyun0. This License Agreement applies to any software library or other program
114*4882a593Smuzhiyunwhich contains a notice placed by the copyright holder or other authorized
115*4882a593Smuzhiyunparty saying it may be distributed under the terms of this Lesser General
116*4882a593SmuzhiyunPublic License (also called "this License"). Each licensee is addressed as
117*4882a593Smuzhiyun"you".
118*4882a593Smuzhiyun
119*4882a593SmuzhiyunA "library" means a collection of software functions and/or data prepared
120*4882a593Smuzhiyunso as to be conveniently linked with application programs (which use some
121*4882a593Smuzhiyunof those functions and data) to form executables.
122*4882a593Smuzhiyun
123*4882a593SmuzhiyunThe "Library", below, refers to any such software library or work which has
124*4882a593Smuzhiyunbeen distributed under these terms. A "work based on the Library" means either
125*4882a593Smuzhiyunthe Library or any derivative work under copyright law: that is to say, a
126*4882a593Smuzhiyunwork containing the Library or a portion of it, either verbatim or with modifications
127*4882a593Smuzhiyunand/or translated straightforwardly into another language. (Hereinafter, translation
128*4882a593Smuzhiyunis included without limitation in the term "modification".)
129*4882a593Smuzhiyun
130*4882a593Smuzhiyun"Source code" for a work means the preferred form of the work for making modifications
131*4882a593Smuzhiyunto it. For a library, complete source code means all the source code for all
132*4882a593Smuzhiyunmodules it contains, plus any associated interface definition files, plus
133*4882a593Smuzhiyunthe scripts used to control compilation and installation of the library.
134*4882a593Smuzhiyun
135*4882a593SmuzhiyunActivities other than copying, distribution and modification are not covered
136*4882a593Smuzhiyunby this License; they are outside its scope. The act of running a program
137*4882a593Smuzhiyunusing the Library is not restricted, and output from such a program is covered
138*4882a593Smuzhiyunonly if its contents constitute a work based on the Library (independent of
139*4882a593Smuzhiyunthe use of the Library in a tool for writing it). Whether that is true depends
140*4882a593Smuzhiyunon what the Library does and what the program that uses the Library does.
141*4882a593Smuzhiyun
142*4882a593Smuzhiyun1. You may copy and distribute verbatim copies of the Library's complete source
143*4882a593Smuzhiyuncode as you receive it, in any medium, provided that you conspicuously and
144*4882a593Smuzhiyunappropriately publish on each copy an appropriate copyright notice and disclaimer
145*4882a593Smuzhiyunof warranty; keep intact all the notices that refer to this License and to
146*4882a593Smuzhiyunthe absence of any warranty; and distribute a copy of this License along with
147*4882a593Smuzhiyunthe Library.
148*4882a593Smuzhiyun
149*4882a593SmuzhiyunYou may charge a fee for the physical act of transferring a copy, and you
150*4882a593Smuzhiyunmay at your option offer warranty protection in exchange for a fee.
151*4882a593Smuzhiyun
152*4882a593Smuzhiyun2. You may modify your copy or copies of the Library or any portion of it,
153*4882a593Smuzhiyunthus forming a work based on the Library, and copy and distribute such modifications
154*4882a593Smuzhiyunor work under the terms of Section 1 above, provided that you also meet all
155*4882a593Smuzhiyunof these conditions:
156*4882a593Smuzhiyun
157*4882a593Smuzhiyun      a) The modified work must itself be a software library.
158*4882a593Smuzhiyun
159*4882a593Smuzhiyunb) You must cause the files modified to carry prominent notices stating that
160*4882a593Smuzhiyunyou changed the files and the date of any change.
161*4882a593Smuzhiyun
162*4882a593Smuzhiyunc) You must cause the whole of the work to be licensed at no charge to all
163*4882a593Smuzhiyunthird parties under the terms of this License.
164*4882a593Smuzhiyun
165*4882a593Smuzhiyund) If a facility in the modified Library refers to a function or a table of
166*4882a593Smuzhiyundata to be supplied by an application program that uses the facility, other
167*4882a593Smuzhiyunthan as an argument passed when the facility is invoked, then you must make
168*4882a593Smuzhiyuna good faith effort to ensure that, in the event an application does not supply
169*4882a593Smuzhiyunsuch function or table, the facility still operates, and performs whatever
170*4882a593Smuzhiyunpart of its purpose remains meaningful.
171*4882a593Smuzhiyun
172*4882a593Smuzhiyun(For example, a function in a library to compute square roots has a purpose
173*4882a593Smuzhiyunthat is entirely well-defined independent of the application. Therefore, Subsection
174*4882a593Smuzhiyun2d requires that any application-supplied function or table used by this function
175*4882a593Smuzhiyunmust be optional: if the application does not supply it, the square root function
176*4882a593Smuzhiyunmust still compute square roots.)
177*4882a593Smuzhiyun
178*4882a593SmuzhiyunThese requirements apply to the modified work as a whole. If identifiable
179*4882a593Smuzhiyunsections of that work are not derived from the Library, and can be reasonably
180*4882a593Smuzhiyunconsidered independent and separate works in themselves, then this License,
181*4882a593Smuzhiyunand its terms, do not apply to those sections when you distribute them as
182*4882a593Smuzhiyunseparate works. But when you distribute the same sections as part of a whole
183*4882a593Smuzhiyunwhich is a work based on the Library, the distribution of the whole must be
184*4882a593Smuzhiyunon the terms of this License, whose permissions for other licensees extend
185*4882a593Smuzhiyunto the entire whole, and thus to each and every part regardless of who wrote
186*4882a593Smuzhiyunit.
187*4882a593Smuzhiyun
188*4882a593SmuzhiyunThus, it is not the intent of this section to claim rights or contest your
189*4882a593Smuzhiyunrights to work written entirely by you; rather, the intent is to exercise
190*4882a593Smuzhiyunthe right to control the distribution of derivative or collective works based
191*4882a593Smuzhiyunon the Library.
192*4882a593Smuzhiyun
193*4882a593SmuzhiyunIn addition, mere aggregation of another work not based on the Library with
194*4882a593Smuzhiyunthe Library (or with a work based on the Library) on a volume of a storage
195*4882a593Smuzhiyunor distribution medium does not bring the other work under the scope of this
196*4882a593SmuzhiyunLicense.
197*4882a593Smuzhiyun
198*4882a593Smuzhiyun3. You may opt to apply the terms of the ordinary GNU General Public License
199*4882a593Smuzhiyuninstead of this License to a given copy of the Library. To do this, you must
200*4882a593Smuzhiyunalter all the notices that refer to this License, so that they refer to the
201*4882a593Smuzhiyunordinary GNU General Public License, version 2, instead of to this License.
202*4882a593Smuzhiyun(If a newer version than version 2 of the ordinary GNU General Public License
203*4882a593Smuzhiyunhas appeared, then you can specify that version instead if you wish.) Do not
204*4882a593Smuzhiyunmake any other change in these notices.
205*4882a593Smuzhiyun
206*4882a593SmuzhiyunOnce this change is made in a given copy, it is irreversible for that copy,
207*4882a593Smuzhiyunso the ordinary GNU General Public License applies to all subsequent copies
208*4882a593Smuzhiyunand derivative works made from that copy.
209*4882a593Smuzhiyun
210*4882a593SmuzhiyunThis option is useful when you wish to copy part of the code of the Library
211*4882a593Smuzhiyuninto a program that is not a library.
212*4882a593Smuzhiyun
213*4882a593Smuzhiyun4. You may copy and distribute the Library (or a portion or derivative of
214*4882a593Smuzhiyunit, under Section 2) in object code or executable form under the terms of
215*4882a593SmuzhiyunSections 1 and 2 above provided that you accompany it with the complete corresponding
216*4882a593Smuzhiyunmachine-readable source code, which must be distributed under the terms of
217*4882a593SmuzhiyunSections 1 and 2 above on a medium customarily used for software interchange.
218*4882a593Smuzhiyun
219*4882a593SmuzhiyunIf distribution of object code is made by offering access to copy from a designated
220*4882a593Smuzhiyunplace, then offering equivalent access to copy the source code from the same
221*4882a593Smuzhiyunplace satisfies the requirement to distribute the source code, even though
222*4882a593Smuzhiyunthird parties are not compelled to copy the source along with the object code.
223*4882a593Smuzhiyun
224*4882a593Smuzhiyun5. A program that contains no derivative of any portion of the Library, but
225*4882a593Smuzhiyunis designed to work with the Library by being compiled or linked with it,
226*4882a593Smuzhiyunis called a "work that uses the Library". Such a work, in isolation, is not
227*4882a593Smuzhiyuna derivative work of the Library, and therefore falls outside the scope of
228*4882a593Smuzhiyunthis License.
229*4882a593Smuzhiyun
230*4882a593SmuzhiyunHowever, linking a "work that uses the Library" with the Library creates an
231*4882a593Smuzhiyunexecutable that is a derivative of the Library (because it contains portions
232*4882a593Smuzhiyunof the Library), rather than a "work that uses the library". The executable
233*4882a593Smuzhiyunis therefore covered by this License. Section 6 states terms for distribution
234*4882a593Smuzhiyunof such executables.
235*4882a593Smuzhiyun
236*4882a593SmuzhiyunWhen a "work that uses the Library" uses material from a header file that
237*4882a593Smuzhiyunis part of the Library, the object code for the work may be a derivative work
238*4882a593Smuzhiyunof the Library even though the source code is not. Whether this is true is
239*4882a593Smuzhiyunespecially significant if the work can be linked without the Library, or if
240*4882a593Smuzhiyunthe work is itself a library. The threshold for this to be true is not precisely
241*4882a593Smuzhiyundefined by law.
242*4882a593Smuzhiyun
243*4882a593SmuzhiyunIf such an object file uses only numerical parameters, data structure layouts
244*4882a593Smuzhiyunand accessors, and small macros and small inline functions (ten lines or less
245*4882a593Smuzhiyunin length), then the use of the object file is unrestricted, regardless of
246*4882a593Smuzhiyunwhether it is legally a derivative work. (Executables containing this object
247*4882a593Smuzhiyuncode plus portions of the Library will still fall under Section 6.)
248*4882a593Smuzhiyun
249*4882a593SmuzhiyunOtherwise, if the work is a derivative of the Library, you may distribute
250*4882a593Smuzhiyunthe object code for the work under the terms of Section 6. Any executables
251*4882a593Smuzhiyuncontaining that work also fall under Section 6, whether or not they are linked
252*4882a593Smuzhiyundirectly with the Library itself.
253*4882a593Smuzhiyun
254*4882a593Smuzhiyun6. As an exception to the Sections above, you may also combine or link a "work
255*4882a593Smuzhiyunthat uses the Library" with the Library to produce a work containing portions
256*4882a593Smuzhiyunof the Library, and distribute that work under terms of your choice, provided
257*4882a593Smuzhiyunthat the terms permit modification of the work for the customer's own use
258*4882a593Smuzhiyunand reverse engineering for debugging such modifications.
259*4882a593Smuzhiyun
260*4882a593SmuzhiyunYou must give prominent notice with each copy of the work that the Library
261*4882a593Smuzhiyunis used in it and that the Library and its use are covered by this License.
262*4882a593SmuzhiyunYou must supply a copy of this License. If the work during execution displays
263*4882a593Smuzhiyuncopyright notices, you must include the copyright notice for the Library among
264*4882a593Smuzhiyunthem, as well as a reference directing the user to the copy of this License.
265*4882a593SmuzhiyunAlso, you must do one of these things:
266*4882a593Smuzhiyun
267*4882a593Smuzhiyuna) Accompany the work with the complete corresponding machine-readable source
268*4882a593Smuzhiyuncode for the Library including whatever changes were used in the work (which
269*4882a593Smuzhiyunmust be distributed under Sections 1 and 2 above); and, if the work is an
270*4882a593Smuzhiyunexecutable linked with the Library, with the complete machine-readable "work
271*4882a593Smuzhiyunthat uses the Library", as object code and/or source code, so that the user
272*4882a593Smuzhiyuncan modify the Library and then relink to produce a modified executable containing
273*4882a593Smuzhiyunthe modified Library. (It is understood that the user who changes the contents
274*4882a593Smuzhiyunof definitions files in the Library will not necessarily be able to recompile
275*4882a593Smuzhiyunthe application to use the modified definitions.)
276*4882a593Smuzhiyun
277*4882a593Smuzhiyunb) Use a suitable shared library mechanism for linking with the Library. A
278*4882a593Smuzhiyunsuitable mechanism is one that (1) uses at run time a copy of the library
279*4882a593Smuzhiyunalready present on the user's computer system, rather than copying library
280*4882a593Smuzhiyunfunctions into the executable, and (2) will operate properly with a modified
281*4882a593Smuzhiyunversion of the library, if the user installs one, as long as the modified
282*4882a593Smuzhiyunversion is interface-compatible with the version that the work was made with.
283*4882a593Smuzhiyun
284*4882a593Smuzhiyunc) Accompany the work with a written offer, valid for at least three years,
285*4882a593Smuzhiyunto give the same user the materials specified in Subsection 6a, above, for
286*4882a593Smuzhiyuna charge no more than the cost of performing this distribution.
287*4882a593Smuzhiyun
288*4882a593Smuzhiyund) If distribution of the work is made by offering access to copy from a designated
289*4882a593Smuzhiyunplace, offer equivalent access to copy the above specified materials from
290*4882a593Smuzhiyunthe same place.
291*4882a593Smuzhiyun
292*4882a593Smuzhiyune) Verify that the user has already received a copy of these materials or
293*4882a593Smuzhiyunthat you have already sent this user a copy.
294*4882a593Smuzhiyun
295*4882a593SmuzhiyunFor an executable, the required form of the "work that uses the Library" must
296*4882a593Smuzhiyuninclude any data and utility programs needed for reproducing the executable
297*4882a593Smuzhiyunfrom it. However, as a special exception, the materials to be distributed
298*4882a593Smuzhiyunneed not include anything that is normally distributed (in either source or
299*4882a593Smuzhiyunbinary form) with the major components (compiler, kernel, and so on) of the
300*4882a593Smuzhiyunoperating system on which the executable runs, unless that component itself
301*4882a593Smuzhiyunaccompanies the executable.
302*4882a593Smuzhiyun
303*4882a593SmuzhiyunIt may happen that this requirement contradicts the license restrictions of
304*4882a593Smuzhiyunother proprietary libraries that do not normally accompany the operating system.
305*4882a593SmuzhiyunSuch a contradiction means you cannot use both them and the Library together
306*4882a593Smuzhiyunin an executable that you distribute.
307*4882a593Smuzhiyun
308*4882a593Smuzhiyun7. You may place library facilities that are a work based on the Library side-by-side
309*4882a593Smuzhiyunin a single library together with other library facilities not covered by
310*4882a593Smuzhiyunthis License, and distribute such a combined library, provided that the separate
311*4882a593Smuzhiyundistribution of the work based on the Library and of the other library facilities
312*4882a593Smuzhiyunis otherwise permitted, and provided that you do these two things:
313*4882a593Smuzhiyun
314*4882a593Smuzhiyuna) Accompany the combined library with a copy of the same work based on the
315*4882a593SmuzhiyunLibrary, uncombined with any other library facilities. This must be distributed
316*4882a593Smuzhiyununder the terms of the Sections above.
317*4882a593Smuzhiyun
318*4882a593Smuzhiyunb) Give prominent notice with the combined library of the fact that part of
319*4882a593Smuzhiyunit is a work based on the Library, and explaining where to find the accompanying
320*4882a593Smuzhiyununcombined form of the same work.
321*4882a593Smuzhiyun
322*4882a593Smuzhiyun8. You may not copy, modify, sublicense, link with, or distribute the Library
323*4882a593Smuzhiyunexcept as expressly provided under this License. Any attempt otherwise to
324*4882a593Smuzhiyuncopy, modify, sublicense, link with, or distribute the Library is void, and
325*4882a593Smuzhiyunwill automatically terminate your rights under this License. However, parties
326*4882a593Smuzhiyunwho have received copies, or rights, from you under this License will not
327*4882a593Smuzhiyunhave their licenses terminated so long as such parties remain in full compliance.
328*4882a593Smuzhiyun
329*4882a593Smuzhiyun9. You are not required to accept this License, since you have not signed
330*4882a593Smuzhiyunit. However, nothing else grants you permission to modify or distribute the
331*4882a593SmuzhiyunLibrary or its derivative works. These actions are prohibited by law if you
332*4882a593Smuzhiyundo not accept this License. Therefore, by modifying or distributing the Library
333*4882a593Smuzhiyun(or any work based on the Library), you indicate your acceptance of this License
334*4882a593Smuzhiyunto do so, and all its terms and conditions for copying, distributing or modifying
335*4882a593Smuzhiyunthe Library or works based on it.
336*4882a593Smuzhiyun
337*4882a593Smuzhiyun10. Each time you redistribute the Library (or any work based on the Library),
338*4882a593Smuzhiyunthe recipient automatically receives a license from the original licensor
339*4882a593Smuzhiyunto copy, distribute, link with or modify the Library subject to these terms
340*4882a593Smuzhiyunand conditions. You may not impose any further restrictions on the recipients'
341*4882a593Smuzhiyunexercise of the rights granted herein. You are not responsible for enforcing
342*4882a593Smuzhiyuncompliance by third parties with this License.
343*4882a593Smuzhiyun
344*4882a593Smuzhiyun11. If, as a consequence of a court judgment or allegation of patent infringement
345*4882a593Smuzhiyunor for any other reason (not limited to patent issues), conditions are imposed
346*4882a593Smuzhiyunon you (whether by court order, agreement or otherwise) that contradict the
347*4882a593Smuzhiyunconditions of this License, they do not excuse you from the conditions of
348*4882a593Smuzhiyunthis License. If you cannot distribute so as to satisfy simultaneously your
349*4882a593Smuzhiyunobligations under this License and any other pertinent obligations, then as
350*4882a593Smuzhiyuna consequence you may not distribute the Library at all. For example, if a
351*4882a593Smuzhiyunpatent license would not permit royalty-free redistribution of the Library
352*4882a593Smuzhiyunby all those who receive copies directly or indirectly through you, then the
353*4882a593Smuzhiyunonly way you could satisfy both it and this License would be to refrain entirely
354*4882a593Smuzhiyunfrom distribution of the Library.
355*4882a593Smuzhiyun
356*4882a593SmuzhiyunIf any portion of this section is held invalid or unenforceable under any
357*4882a593Smuzhiyunparticular circumstance, the balance of the section is intended to apply,
358*4882a593Smuzhiyunand the section as a whole is intended to apply in other circumstances.
359*4882a593Smuzhiyun
360*4882a593SmuzhiyunIt is not the purpose of this section to induce you to infringe any patents
361*4882a593Smuzhiyunor other property right claims or to contest validity of any such claims;
362*4882a593Smuzhiyunthis section has the sole purpose of protecting the integrity of the free
363*4882a593Smuzhiyunsoftware distribution system which is implemented by public license practices.
364*4882a593SmuzhiyunMany people have made generous contributions to the wide range of software
365*4882a593Smuzhiyundistributed through that system in reliance on consistent application of that
366*4882a593Smuzhiyunsystem; it is up to the author/donor to decide if he or she is willing to
367*4882a593Smuzhiyundistribute software through any other system and a licensee cannot impose
368*4882a593Smuzhiyunthat choice.
369*4882a593Smuzhiyun
370*4882a593SmuzhiyunThis section is intended to make thoroughly clear what is believed to be a
371*4882a593Smuzhiyunconsequence of the rest of this License.
372*4882a593Smuzhiyun
373*4882a593Smuzhiyun12. If the distribution and/or use of the Library is restricted in certain
374*4882a593Smuzhiyuncountries either by patents or by copyrighted interfaces, the original copyright
375*4882a593Smuzhiyunholder who places the Library under this License may add an explicit geographical
376*4882a593Smuzhiyundistribution limitation excluding those countries, so that distribution is
377*4882a593Smuzhiyunpermitted only in or among countries not thus excluded. In such case, this
378*4882a593SmuzhiyunLicense incorporates the limitation as if written in the body of this License.
379*4882a593Smuzhiyun
380*4882a593Smuzhiyun13. The Free Software Foundation may publish revised and/or new versions of
381*4882a593Smuzhiyunthe Lesser General Public License from time to time. Such new versions will
382*4882a593Smuzhiyunbe similar in spirit to the present version, but may differ in detail to address
383*4882a593Smuzhiyunnew problems or concerns.
384*4882a593Smuzhiyun
385*4882a593SmuzhiyunEach version is given a distinguishing version number. If the Library specifies
386*4882a593Smuzhiyuna version number of this License which applies to it and "any later version",
387*4882a593Smuzhiyunyou have the option of following the terms and conditions either of that version
388*4882a593Smuzhiyunor of any later version published by the Free Software Foundation. If the
389*4882a593SmuzhiyunLibrary does not specify a license version number, you may choose any version
390*4882a593Smuzhiyunever published by the Free Software Foundation.
391*4882a593Smuzhiyun
392*4882a593Smuzhiyun14. If you wish to incorporate parts of the Library into other free programs
393*4882a593Smuzhiyunwhose distribution conditions are incompatible with these, write to the author
394*4882a593Smuzhiyunto ask for permission. For software which is copyrighted by the Free Software
395*4882a593SmuzhiyunFoundation, write to the Free Software Foundation; we sometimes make exceptions
396*4882a593Smuzhiyunfor this. Our decision will be guided by the two goals of preserving the free
397*4882a593Smuzhiyunstatus of all derivatives of our free software and of promoting the sharing
398*4882a593Smuzhiyunand reuse of software generally.
399*4882a593Smuzhiyun
400*4882a593Smuzhiyun   NO WARRANTY
401*4882a593Smuzhiyun
402*4882a593Smuzhiyun15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
403*4882a593SmuzhiyunTHE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
404*4882a593SmuzhiyunSTATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
405*4882a593Smuzhiyun"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
406*4882a593SmuzhiyunBUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
407*4882a593SmuzhiyunFOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
408*4882a593SmuzhiyunOF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
409*4882a593SmuzhiyunTHE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
410*4882a593Smuzhiyun
411*4882a593Smuzhiyun16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
412*4882a593SmuzhiyunWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
413*4882a593SmuzhiyunTHE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
414*4882a593SmuzhiyunGENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
415*4882a593SmuzhiyunOR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
416*4882a593SmuzhiyunOR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
417*4882a593SmuzhiyunOR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH
418*4882a593SmuzhiyunHOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

420*4882a593Smuzhiyun
421*4882a593SmuzhiyunHow to Apply These Terms to Your New Libraries
422*4882a593Smuzhiyun
423*4882a593SmuzhiyunIf you develop a new library, and you want it to be of the greatest possible
424*4882a593Smuzhiyunuse to the public, we recommend making it free software that everyone can
425*4882a593Smuzhiyunredistribute and change. You can do so by permitting redistribution under
426*4882a593Smuzhiyunthese terms (or, alternatively, under the terms of the ordinary General Public
427*4882a593SmuzhiyunLicense).
428*4882a593Smuzhiyun
429*4882a593SmuzhiyunTo apply these terms, attach the following notices to the library. It is safest
430*4882a593Smuzhiyunto attach them to the start of each source file to most effectively convey
431*4882a593Smuzhiyunthe exclusion of warranty; and each file should have at least the "copyright"
432*4882a593Smuzhiyunline and a pointer to where the full notice is found.
