4*4882a593SmuzhiyunThe FLTK library and included programs are provided under the terms
5*4882a593Smuzhiyunof the GNU Library General Public License (LGPL) with the following
6*4882a593Smuzhiyunexceptions:
7*4882a593Smuzhiyun
8*4882a593Smuzhiyun    1. Modifications to the FLTK configure script, config
9*4882a593Smuzhiyun       header file, and makefiles by themselves to support
10*4882a593Smuzhiyun       a specific platform do not constitute a modified or
11*4882a593Smuzhiyun       derivative work.
12*4882a593Smuzhiyun
13*4882a593Smuzhiyun      The authors do request that such modifications be
14*4882a593Smuzhiyun      contributed to the FLTK project - send all contributions
15*4882a593Smuzhiyun      through the "Software Trouble Report" on the following page:

17*4882a593Smuzhiyun           http://www.fltk.org/str.php
18*4882a593Smuzhiyun
19*4882a593Smuzhiyun    2. Widgets that are subclassed from FLTK widgets do not
20*4882a593Smuzhiyun       constitute a derivative work.
21*4882a593Smuzhiyun
22*4882a593Smuzhiyun    3. Static linking of applications and widgets to the
23*4882a593Smuzhiyun       FLTK library does not constitute a derivative work
24*4882a593Smuzhiyun       and does not require the author to provide source
25*4882a593Smuzhiyun       code for the application or widget, use the shared
26*4882a593Smuzhiyun       FLTK libraries, or link their applications or
27*4882a593Smuzhiyun       widgets against a user-supplied version of FLTK.
28*4882a593Smuzhiyun
29*4882a593Smuzhiyun       If you link the application or widget to a modified
30*4882a593Smuzhiyun       version of FLTK, then the changes to FLTK must be
31*4882a593Smuzhiyun       provided under the terms of the LGPL in sections
32*4882a593Smuzhiyun       1, 2, and 4.
33*4882a593Smuzhiyun
34*4882a593Smuzhiyun    4. You do not have to provide a copy of the FLTK license
35*4882a593Smuzhiyun       with programs that are linked to the FLTK library, nor
36*4882a593Smuzhiyun       do you have to identify the FLTK license in your
37*4882a593Smuzhiyun       program or documentation as required by section 6
38*4882a593Smuzhiyun       of the LGPL.
39*4882a593Smuzhiyun
40*4882a593Smuzhiyun       However, programs must still identify their use of FLTK.
41*4882a593Smuzhiyun       The following example statement can be included in user
42*4882a593Smuzhiyun       documentation to satisfy this requirement:
43*4882a593Smuzhiyun
44*4882a593Smuzhiyun           [program/widget] is based in part on the work of
45*4882a593Smuzhiyun           the FLTK project (http://www.fltk.org).

55*4882a593Smuzhiyun     Everyone is permitted to copy and distribute verbatim copies
56*4882a593Smuzhiyun      of this license document, but changing it is not allowed.
57*4882a593Smuzhiyun
58*4882a593Smuzhiyun    [This is the first released version of the library GPL.  It is
59*4882a593Smuzhiyun   numbered 2 because it goes with version 2 of the ordinary GPL.]
60*4882a593Smuzhiyun
61*4882a593Smuzhiyun			       Preamble
62*4882a593Smuzhiyun
63*4882a593Smuzhiyun  The licenses for most software are designed to take away your
64*4882a593Smuzhiyunfreedom to share and change it.  By contrast, the GNU General Public
65*4882a593SmuzhiyunLicenses are intended to guarantee your freedom to share and change
66*4882a593Smuzhiyunfree software--to make sure the software is free for all its users.
67*4882a593Smuzhiyun
68*4882a593Smuzhiyun  This license, the Library General Public License, applies to some
69*4882a593Smuzhiyunspecially designated Free Software Foundation software, and to any
70*4882a593Smuzhiyunother libraries whose authors decide to use it.  You can use it for
71*4882a593Smuzhiyunyour libraries, too.
72*4882a593Smuzhiyun
73*4882a593Smuzhiyun  When we speak of free software, we are referring to freedom, not
74*4882a593Smuzhiyunprice.  Our General Public Licenses are designed to make sure that you
75*4882a593Smuzhiyunhave the freedom to distribute copies of free software (and charge for
76*4882a593Smuzhiyunthis service if you wish), that you receive source code or can get it
77*4882a593Smuzhiyunif you want it, that you can change the software or use pieces of it
78*4882a593Smuzhiyunin new free programs; and that you know you can do these things.
79*4882a593Smuzhiyun
80*4882a593Smuzhiyun  To protect your rights, we need to make restrictions that forbid
81*4882a593Smuzhiyunanyone to deny you these rights or to ask you to surrender the rights.
82*4882a593SmuzhiyunThese restrictions translate to certain responsibilities for you if
83*4882a593Smuzhiyunyou distribute copies of the library, or if you modify it.
84*4882a593Smuzhiyun
85*4882a593Smuzhiyun  For example, if you distribute copies of the library, whether gratis
86*4882a593Smuzhiyunor for a fee, you must give the recipients all the rights that we gave
87*4882a593Smuzhiyunyou.  You must make sure that they, too, receive or can get the source
88*4882a593Smuzhiyuncode.  If you link a program with the library, you must provide
89*4882a593Smuzhiyuncomplete object files to the recipients so that they can relink them
90*4882a593Smuzhiyunwith the library, after making changes to the library and recompiling
91*4882a593Smuzhiyunit.  And you must show them these terms so they know their rights.
92*4882a593Smuzhiyun
93*4882a593Smuzhiyun  Our method of protecting your rights has two steps: (1) copyright
94*4882a593Smuzhiyunthe library, and (2) offer you this license which gives you legal
95*4882a593Smuzhiyunpermission to copy, distribute and/or modify the library.
96*4882a593Smuzhiyun
97*4882a593Smuzhiyun  Also, for each distributor's protection, we want to make certain
98*4882a593Smuzhiyunthat everyone understands that there is no warranty for this free
99*4882a593Smuzhiyunlibrary.  If the library is modified by someone else and passed on, we
100*4882a593Smuzhiyunwant its recipients to know that what they have is not the original
101*4882a593Smuzhiyunversion, so that any problems introduced by others will not reflect on
102*4882a593Smuzhiyunthe original authors' reputations.
103*4882a593Smuzhiyun
104*4882a593Smuzhiyun  Finally, any free program is threatened constantly by software
105*4882a593Smuzhiyunpatents.  We wish to avoid the danger that companies distributing free
106*4882a593Smuzhiyunsoftware will individually obtain patent licenses, thus in effect
107*4882a593Smuzhiyuntransforming the program into proprietary software.  To prevent this,
108*4882a593Smuzhiyunwe have made it clear that any patent must be licensed for everyone's
109*4882a593Smuzhiyunfree use or not licensed at all.
110*4882a593Smuzhiyun
111*4882a593Smuzhiyun  Most GNU software, including some libraries, is covered by the ordinary
112*4882a593SmuzhiyunGNU General Public License, which was designed for utility programs.  This
113*4882a593Smuzhiyunlicense, the GNU Library General Public License, applies to certain
114*4882a593Smuzhiyundesignated libraries.  This license is quite different from the ordinary
115*4882a593Smuzhiyunone; be sure to read it in full, and don't assume that anything in it is
116*4882a593Smuzhiyunthe same as in the ordinary license.
117*4882a593Smuzhiyun
118*4882a593Smuzhiyun  The reason we have a separate public license for some libraries is that
119*4882a593Smuzhiyunthey blur the distinction we usually make between modifying or adding to a
120*4882a593Smuzhiyunprogram and simply using it.  Linking a program with a library, without
121*4882a593Smuzhiyunchanging the library, is in some sense simply using the library, and is
122*4882a593Smuzhiyunanalogous to running a utility program or application program.  However, in
123*4882a593Smuzhiyuna textual and legal sense, the linked executable is a combined work, a
124*4882a593Smuzhiyunderivative of the original library, and the ordinary General Public License
125*4882a593Smuzhiyuntreats it as such.
126*4882a593Smuzhiyun
127*4882a593Smuzhiyun  Because of this blurred distinction, using the ordinary General
128*4882a593SmuzhiyunPublic License for libraries did not effectively promote software
129*4882a593Smuzhiyunsharing, because most developers did not use the libraries.  We
130*4882a593Smuzhiyunconcluded that weaker conditions might promote sharing better.
131*4882a593Smuzhiyun
132*4882a593Smuzhiyun  However, unrestricted linking of non-free programs would deprive the
133*4882a593Smuzhiyunusers of those programs of all benefit from the free status of the
134*4882a593Smuzhiyunlibraries themselves.  This Library General Public License is intended to
135*4882a593Smuzhiyunpermit developers of non-free programs to use free libraries, while
136*4882a593Smuzhiyunpreserving your freedom as a user of such programs to change the free
137*4882a593Smuzhiyunlibraries that are incorporated in them.  (We have not seen how to achieve
138*4882a593Smuzhiyunthis as regards changes in header files, but we have achieved it as regards
139*4882a593Smuzhiyunchanges in the actual functions of the Library.)  The hope is that this
140*4882a593Smuzhiyunwill lead to faster development of free libraries.
141*4882a593Smuzhiyun
142*4882a593Smuzhiyun  The precise terms and conditions for copying, distribution and
143*4882a593Smuzhiyunmodification follow.  Pay close attention to the difference between a
144*4882a593Smuzhiyun"work based on the library" and a "work that uses the library".  The
145*4882a593Smuzhiyunformer contains code derived from the library, while the latter only
146*4882a593Smuzhiyunworks together with the library.
147*4882a593Smuzhiyun
148*4882a593Smuzhiyun  Note that it is possible for a library to be covered by the ordinary
149*4882a593SmuzhiyunGeneral Public License rather than by this special one.
150*4882a593Smuzhiyun
151*4882a593Smuzhiyun		  GNU LIBRARY GENERAL PUBLIC LICENSE
152*4882a593Smuzhiyun   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
153*4882a593Smuzhiyun
154*4882a593Smuzhiyun  0. This License Agreement applies to any software library which
155*4882a593Smuzhiyuncontains a notice placed by the copyright holder or other authorized
156*4882a593Smuzhiyunparty saying it may be distributed under the terms of this Library
157*4882a593SmuzhiyunGeneral Public License (also called "this License").  Each licensee is
158*4882a593Smuzhiyunaddressed as "you".
159*4882a593Smuzhiyun
160*4882a593Smuzhiyun  A "library" means a collection of software functions and/or data
161*4882a593Smuzhiyunprepared so as to be conveniently linked with application programs
162*4882a593Smuzhiyun(which use some of those functions and data) to form executables.
163*4882a593Smuzhiyun
164*4882a593Smuzhiyun  The "Library", below, refers to any such software library or work
165*4882a593Smuzhiyunwhich has been distributed under these terms.  A "work based on the
166*4882a593SmuzhiyunLibrary" means either the Library or any derivative work under
167*4882a593Smuzhiyuncopyright law: that is to say, a work containing the Library or a
168*4882a593Smuzhiyunportion of it, either verbatim or with modifications and/or translated
169*4882a593Smuzhiyunstraightforwardly into another language.  (Hereinafter, translation is
170*4882a593Smuzhiyunincluded without limitation in the term "modification".)
171*4882a593Smuzhiyun
172*4882a593Smuzhiyun  "Source code" for a work means the preferred form of the work for
173*4882a593Smuzhiyunmaking modifications to it.  For a library, complete source code means
174*4882a593Smuzhiyunall the source code for all modules it contains, plus any associated
175*4882a593Smuzhiyuninterface definition files, plus the scripts used to control compilation
176*4882a593Smuzhiyunand installation of the library.
177*4882a593Smuzhiyun
178*4882a593Smuzhiyun  Activities other than copying, distribution and modification are not
179*4882a593Smuzhiyuncovered by this License; they are outside its scope.  The act of
180*4882a593Smuzhiyunrunning a program using the Library is not restricted, and output from
181*4882a593Smuzhiyunsuch a program is covered only if its contents constitute a work based
182*4882a593Smuzhiyunon the Library (independent of the use of the Library in a tool for
183*4882a593Smuzhiyunwriting it).  Whether that is true depends on what the Library does
184*4882a593Smuzhiyunand what the program that uses the Library does.
185*4882a593Smuzhiyun
186*4882a593Smuzhiyun  1. You may copy and distribute verbatim copies of the Library's
187*4882a593Smuzhiyuncomplete source code as you receive it, in any medium, provided that
188*4882a593Smuzhiyunyou conspicuously and appropriately publish on each copy an
189*4882a593Smuzhiyunappropriate copyright notice and disclaimer of warranty; keep intact
190*4882a593Smuzhiyunall the notices that refer to this License and to the absence of any
191*4882a593Smuzhiyunwarranty; and distribute a copy of this License along with the
192*4882a593SmuzhiyunLibrary.
193*4882a593Smuzhiyun
194*4882a593Smuzhiyun  You may charge a fee for the physical act of transferring a copy,
195*4882a593Smuzhiyunand you may at your option offer warranty protection in exchange for a
196*4882a593Smuzhiyunfee.
197*4882a593Smuzhiyun
198*4882a593Smuzhiyun  2. You may modify your copy or copies of the Library or any portion
199*4882a593Smuzhiyunof it, thus forming a work based on the Library, and copy and
200*4882a593Smuzhiyundistribute such modifications or work under the terms of Section 1
201*4882a593Smuzhiyunabove, provided that you also meet all of these conditions:
202*4882a593Smuzhiyun
203*4882a593Smuzhiyun    a) The modified work must itself be a software library.
204*4882a593Smuzhiyun
205*4882a593Smuzhiyun    b) You must cause the files modified to carry prominent notices
206*4882a593Smuzhiyun    stating that you changed the files and the date of any change.
207*4882a593Smuzhiyun
208*4882a593Smuzhiyun    c) You must cause the whole of the work to be licensed at no
209*4882a593Smuzhiyun    charge to all third parties under the terms of this License.
210*4882a593Smuzhiyun
211*4882a593Smuzhiyun    d) If a facility in the modified Library refers to a function or a
212*4882a593Smuzhiyun    table of data to be supplied by an application program that uses
213*4882a593Smuzhiyun    the facility, other than as an argument passed when the facility
214*4882a593Smuzhiyun    is invoked, then you must make a good faith effort to ensure that,
215*4882a593Smuzhiyun    in the event an application does not supply such function or
216*4882a593Smuzhiyun    table, the facility still operates, and performs whatever part of
217*4882a593Smuzhiyun    its purpose remains meaningful.
218*4882a593Smuzhiyun
219*4882a593Smuzhiyun    (For example, a function in a library to compute square roots has
220*4882a593Smuzhiyun    a purpose that is entirely well-defined independent of the
221*4882a593Smuzhiyun    application.  Therefore, Subsection 2d requires that any
222*4882a593Smuzhiyun    application-supplied function or table used by this function must
223*4882a593Smuzhiyun    be optional: if the application does not supply it, the square
224*4882a593Smuzhiyun    root function must still compute square roots.)
225*4882a593Smuzhiyun
226*4882a593SmuzhiyunThese requirements apply to the modified work as a whole.  If
227*4882a593Smuzhiyunidentifiable sections of that work are not derived from the Library,
228*4882a593Smuzhiyunand can be reasonably considered independent and separate works in
229*4882a593Smuzhiyunthemselves, then this License, and its terms, do not apply to those
230*4882a593Smuzhiyunsections when you distribute them as separate works.  But when you
231*4882a593Smuzhiyundistribute the same sections as part of a whole which is a work based
232*4882a593Smuzhiyunon the Library, the distribution of the whole must be on the terms of
233*4882a593Smuzhiyunthis License, whose permissions for other licensees extend to the
234*4882a593Smuzhiyunentire whole, and thus to each and every part regardless of who wrote
235*4882a593Smuzhiyunit.
236*4882a593Smuzhiyun
237*4882a593SmuzhiyunThus, it is not the intent of this section to claim rights or contest
238*4882a593Smuzhiyunyour rights to work written entirely by you; rather, the intent is to
239*4882a593Smuzhiyunexercise the right to control the distribution of derivative or
240*4882a593Smuzhiyuncollective works based on the Library.
241*4882a593Smuzhiyun
242*4882a593SmuzhiyunIn addition, mere aggregation of another work not based on the Library
243*4882a593Smuzhiyunwith the Library (or with a work based on the Library) on a volume of
244*4882a593Smuzhiyuna storage or distribution medium does not bring the other work under
245*4882a593Smuzhiyunthe scope of this License.
246*4882a593Smuzhiyun
247*4882a593Smuzhiyun  3. You may opt to apply the terms of the ordinary GNU General Public
248*4882a593SmuzhiyunLicense instead of this License to a given copy of the Library.  To do
249*4882a593Smuzhiyunthis, you must alter all the notices that refer to this License, so
250*4882a593Smuzhiyunthat they refer to the ordinary GNU General Public License, version 2,
251*4882a593Smuzhiyuninstead of to this License.  (If a newer version than version 2 of the
252*4882a593Smuzhiyunordinary GNU General Public License has appeared, then you can specify
253*4882a593Smuzhiyunthat version instead if you wish.)  Do not make any other change in
254*4882a593Smuzhiyunthese notices.
255*4882a593Smuzhiyun
256*4882a593Smuzhiyun  Once this change is made in a given copy, it is irreversible for
257*4882a593Smuzhiyunthat copy, so the ordinary GNU General Public License applies to all
258*4882a593Smuzhiyunsubsequent copies and derivative works made from that copy.
259*4882a593Smuzhiyun
260*4882a593Smuzhiyun  This option is useful when you wish to copy part of the code of
261*4882a593Smuzhiyunthe Library into a program that is not a library.
262*4882a593Smuzhiyun
263*4882a593Smuzhiyun  4. You may copy and distribute the Library (or a portion or
264*4882a593Smuzhiyunderivative of it, under Section 2) in object code or executable form
265*4882a593Smuzhiyununder the terms of Sections 1 and 2 above provided that you accompany
266*4882a593Smuzhiyunit with the complete corresponding machine-readable source code, which
267*4882a593Smuzhiyunmust be distributed under the terms of Sections 1 and 2 above on a
268*4882a593Smuzhiyunmedium customarily used for software interchange.
269*4882a593Smuzhiyun
270*4882a593Smuzhiyun  If distribution of object code is made by offering access to copy
271*4882a593Smuzhiyunfrom a designated place, then offering equivalent access to copy the
272*4882a593Smuzhiyunsource code from the same place satisfies the requirement to
273*4882a593Smuzhiyundistribute the source code, even though third parties are not
274*4882a593Smuzhiyuncompelled to copy the source along with the object code.
275*4882a593Smuzhiyun
276*4882a593Smuzhiyun  5. A program that contains no derivative of any portion of the
277*4882a593SmuzhiyunLibrary, but is designed to work with the Library by being compiled or
278*4882a593Smuzhiyunlinked with it, is called a "work that uses the Library".  Such a
279*4882a593Smuzhiyunwork, in isolation, is not a derivative work of the Library, and
280*4882a593Smuzhiyuntherefore falls outside the scope of this License.
281*4882a593Smuzhiyun
282*4882a593Smuzhiyun  However, linking a "work that uses the Library" with the Library
283*4882a593Smuzhiyuncreates an executable that is a derivative of the Library (because it
284*4882a593Smuzhiyuncontains portions of the Library), rather than a "work that uses the
285*4882a593Smuzhiyunlibrary".  The executable is therefore covered by this License.
286*4882a593SmuzhiyunSection 6 states terms for distribution of such executables.
287*4882a593Smuzhiyun
288*4882a593Smuzhiyun  When a "work that uses the Library" uses material from a header file
289*4882a593Smuzhiyunthat is part of the Library, the object code for the work may be a
290*4882a593Smuzhiyunderivative work of the Library even though the source code is not.
291*4882a593SmuzhiyunWhether this is true is especially significant if the work can be
292*4882a593Smuzhiyunlinked without the Library, or if the work is itself a library.  The
293*4882a593Smuzhiyunthreshold for this to be true is not precisely defined by law.
294*4882a593Smuzhiyun
295*4882a593Smuzhiyun  If such an object file uses only numerical parameters, data
296*4882a593Smuzhiyunstructure layouts and accessors, and small macros and small inline
297*4882a593Smuzhiyunfunctions (ten lines or less in length), then the use of the object
298*4882a593Smuzhiyunfile is unrestricted, regardless of whether it is legally a derivative
299*4882a593Smuzhiyunwork.  (Executables containing this object code plus portions of the
300*4882a593SmuzhiyunLibrary will still fall under Section 6.)
301*4882a593Smuzhiyun
302*4882a593Smuzhiyun  Otherwise, if the work is a derivative of the Library, you may
303*4882a593Smuzhiyundistribute the object code for the work under the terms of Section 6.
304*4882a593SmuzhiyunAny executables containing that work also fall under Section 6,
305*4882a593Smuzhiyunwhether or not they are linked directly with the Library itself.
306*4882a593Smuzhiyun
307*4882a593Smuzhiyun  6. As an exception to the Sections above, you may also compile or
308*4882a593Smuzhiyunlink a "work that uses the Library" with the Library to produce a
309*4882a593Smuzhiyunwork containing portions of the Library, and distribute that work
310*4882a593Smuzhiyununder terms of your choice, provided that the terms permit
311*4882a593Smuzhiyunmodification of the work for the customer's own use and reverse
312*4882a593Smuzhiyunengineering for debugging such modifications.
313*4882a593Smuzhiyun
314*4882a593Smuzhiyun  You must give prominent notice with each copy of the work that the
315*4882a593SmuzhiyunLibrary is used in it and that the Library and its use are covered by
316*4882a593Smuzhiyunthis License.  You must supply a copy of this License.  If the work
317*4882a593Smuzhiyunduring execution displays copyright notices, you must include the
318*4882a593Smuzhiyuncopyright notice for the Library among them, as well as a reference
319*4882a593Smuzhiyundirecting the user to the copy of this License.  Also, you must do one
320*4882a593Smuzhiyunof these things:
321*4882a593Smuzhiyun
322*4882a593Smuzhiyun    a) Accompany the work with the complete corresponding
323*4882a593Smuzhiyun    machine-readable source code for the Library including whatever
324*4882a593Smuzhiyun    changes were used in the work (which must be distributed under
325*4882a593Smuzhiyun    Sections 1 and 2 above); and, if the work is an executable linked
326*4882a593Smuzhiyun    with the Library, with the complete machine-readable "work that
327*4882a593Smuzhiyun    uses the Library", as object code and/or source code, so that the
328*4882a593Smuzhiyun    user can modify the Library and then relink to produce a modified
329*4882a593Smuzhiyun    executable containing the modified Library.  (It is understood
330*4882a593Smuzhiyun    that the user who changes the contents of definitions files in the
331*4882a593Smuzhiyun    Library will not necessarily be able to recompile the application
332*4882a593Smuzhiyun    to use the modified definitions.)
333*4882a593Smuzhiyun
334*4882a593Smuzhiyun    b) Accompany the work with a written offer, valid for at
335*4882a593Smuzhiyun    least three years, to give the same user the materials
336*4882a593Smuzhiyun    specified in Subsection 6a, above, for a charge no more
337*4882a593Smuzhiyun    than the cost of performing this distribution.
338*4882a593Smuzhiyun
339*4882a593Smuzhiyun    c) If distribution of the work is made by offering access to copy
340*4882a593Smuzhiyun    from a designated place, offer equivalent access to copy the above
341*4882a593Smuzhiyun    specified materials from the same place.
342*4882a593Smuzhiyun
343*4882a593Smuzhiyun    d) Verify that the user has already received a copy of these
344*4882a593Smuzhiyun    materials or that you have already sent this user a copy.
345*4882a593Smuzhiyun
346*4882a593Smuzhiyun  For an executable, the required form of the "work that uses the
347*4882a593SmuzhiyunLibrary" must include any data and utility programs needed for
348*4882a593Smuzhiyunreproducing the executable from it.  However, as a special exception,
349*4882a593Smuzhiyunthe source code distributed need not include anything that is normally
350*4882a593Smuzhiyundistributed (in either source or binary form) with the major
351*4882a593Smuzhiyuncomponents (compiler, kernel, and so on) of the operating system on
352*4882a593Smuzhiyunwhich the executable runs, unless that component itself accompanies
353*4882a593Smuzhiyunthe executable.
354*4882a593Smuzhiyun
355*4882a593Smuzhiyun  It may happen that this requirement contradicts the license
356*4882a593Smuzhiyunrestrictions of other proprietary libraries that do not normally
357*4882a593Smuzhiyunaccompany the operating system.  Such a contradiction means you cannot
358*4882a593Smuzhiyunuse both them and the Library together in an executable that you
359*4882a593Smuzhiyundistribute.
360*4882a593Smuzhiyun
361*4882a593Smuzhiyun  7. You may place library facilities that are a work based on the
362*4882a593SmuzhiyunLibrary side-by-side in a single library together with other library
363*4882a593Smuzhiyunfacilities not covered by this License, and distribute such a combined
364*4882a593Smuzhiyunlibrary, provided that the separate distribution of the work based on
365*4882a593Smuzhiyunthe Library and of the other library facilities is otherwise
366*4882a593Smuzhiyunpermitted, and provided that you do these two things:
367*4882a593Smuzhiyun
368*4882a593Smuzhiyun    a) Accompany the combined library with a copy of the same work
369*4882a593Smuzhiyun    based on the Library, uncombined with any other library
370*4882a593Smuzhiyun    facilities.  This must be distributed under the terms of the
371*4882a593Smuzhiyun    Sections above.
372*4882a593Smuzhiyun
373*4882a593Smuzhiyun    b) Give prominent notice with the combined library of the fact
374*4882a593Smuzhiyun    that part of it is a work based on the Library, and explaining
375*4882a593Smuzhiyun    where to find the accompanying uncombined form of the same work.
376*4882a593Smuzhiyun
377*4882a593Smuzhiyun  8. You may not copy, modify, sublicense, link with, or distribute
378*4882a593Smuzhiyunthe Library except as expressly provided under this License.  Any
379*4882a593Smuzhiyunattempt otherwise to copy, modify, sublicense, link with, or
380*4882a593Smuzhiyundistribute the Library is void, and will automatically terminate your
381*4882a593Smuzhiyunrights under this License.  However, parties who have received copies,
382*4882a593Smuzhiyunor rights, from you under this License will not have their licenses
383*4882a593Smuzhiyunterminated so long as such parties remain in full compliance.
384*4882a593Smuzhiyun
385*4882a593Smuzhiyun  9. You are not required to accept this License, since you have not
386*4882a593Smuzhiyunsigned it.  However, nothing else grants you permission to modify or
387*4882a593Smuzhiyundistribute the Library or its derivative works.  These actions are
388*4882a593Smuzhiyunprohibited by law if you do not accept this License.  Therefore, by
389*4882a593Smuzhiyunmodifying or distributing the Library (or any work based on the
390*4882a593SmuzhiyunLibrary), you indicate your acceptance of this License to do so, and
391*4882a593Smuzhiyunall its terms and conditions for copying, distributing or modifying
392*4882a593Smuzhiyunthe Library or works based on it.
393*4882a593Smuzhiyun
394*4882a593Smuzhiyun  10. Each time you redistribute the Library (or any work based on the
395*4882a593SmuzhiyunLibrary), the recipient automatically receives a license from the
396*4882a593Smuzhiyunoriginal licensor to copy, distribute, link with or modify the Library
397*4882a593Smuzhiyunsubject to these terms and conditions.  You may not impose any further
398*4882a593Smuzhiyunrestrictions on the recipients' exercise of the rights granted herein.
399*4882a593SmuzhiyunYou are not responsible for enforcing compliance by third parties to
400*4882a593Smuzhiyunthis License.
401*4882a593Smuzhiyun
402*4882a593Smuzhiyun  11. If, as a consequence of a court judgment or allegation of patent
403*4882a593Smuzhiyuninfringement or for any other reason (not limited to patent issues),
404*4882a593Smuzhiyunconditions are imposed on you (whether by court order, agreement or
405*4882a593Smuzhiyunotherwise) that contradict the conditions of this License, they do not
406*4882a593Smuzhiyunexcuse you from the conditions of this License.  If you cannot
407*4882a593Smuzhiyundistribute so as to satisfy simultaneously your obligations under this
408*4882a593SmuzhiyunLicense and any other pertinent obligations, then as a consequence you
409*4882a593Smuzhiyunmay not distribute the Library at all.  For example, if a patent
410*4882a593Smuzhiyunlicense would not permit royalty-free redistribution of the Library by
411*4882a593Smuzhiyunall those who receive copies directly or indirectly through you, then
412*4882a593Smuzhiyunthe only way you could satisfy both it and this License would be to
413*4882a593Smuzhiyunrefrain entirely from distribution of the Library.
414*4882a593Smuzhiyun
415*4882a593SmuzhiyunIf any portion of this section is held invalid or unenforceable under any
416*4882a593Smuzhiyunparticular circumstance, the balance of the section is intended to apply,
417*4882a593Smuzhiyunand the section as a whole is intended to apply in other circumstances.
418*4882a593Smuzhiyun
419*4882a593SmuzhiyunIt is not the purpose of this section to induce you to infringe any
420*4882a593Smuzhiyunpatents or other property right claims or to contest validity of any
421*4882a593Smuzhiyunsuch claims; this section has the sole purpose of protecting the
422*4882a593Smuzhiyunintegrity of the free software distribution system which is
423*4882a593Smuzhiyunimplemented by public license practices.  Many people have made
424*4882a593Smuzhiyungenerous contributions to the wide range of software distributed
425*4882a593Smuzhiyunthrough that system in reliance on consistent application of that
426*4882a593Smuzhiyunsystem; it is up to the author/donor to decide if he or she is willing
427*4882a593Smuzhiyunto distribute software through any other system and a licensee cannot
428*4882a593Smuzhiyunimpose that choice.
429*4882a593Smuzhiyun
430*4882a593SmuzhiyunThis section is intended to make thoroughly clear what is believed to
431*4882a593Smuzhiyunbe a consequence of the rest of this License.
432*4882a593Smuzhiyun
433*4882a593Smuzhiyun  12. If the distribution and/or use of the Library is restricted in
434*4882a593Smuzhiyuncertain countries either by patents or by copyrighted interfaces, the
435*4882a593Smuzhiyunoriginal copyright holder who places the Library under this License may add
436*4882a593Smuzhiyunan explicit geographical distribution limitation excluding those countries,
437*4882a593Smuzhiyunso that distribution is permitted only in or among countries not thus
438*4882a593Smuzhiyunexcluded.  In such case, this License incorporates the limitation as if
439*4882a593Smuzhiyunwritten in the body of this License.
440*4882a593Smuzhiyun
441*4882a593Smuzhiyun  13. The Free Software Foundation may publish revised and/or new
442*4882a593Smuzhiyunversions of the Library General Public License from time to time.
443*4882a593SmuzhiyunSuch new versions will be similar in spirit to the present version,
444*4882a593Smuzhiyunbut may differ in detail to address new problems or concerns.
445*4882a593Smuzhiyun
446*4882a593SmuzhiyunEach version is given a distinguishing version number.  If the Library
447*4882a593Smuzhiyunspecifies a version number of this License which applies to it and
448*4882a593Smuzhiyun"any later version", you have the option of following the terms and
449*4882a593Smuzhiyunconditions either of that version or of any later version published by
450*4882a593Smuzhiyunthe Free Software Foundation.  If the Library does not specify a
451*4882a593Smuzhiyunlicense version number, you may choose any version ever published by
452*4882a593Smuzhiyunthe Free Software Foundation.
453*4882a593Smuzhiyun
454*4882a593Smuzhiyun  14. If you wish to incorporate parts of the Library into other free
455*4882a593Smuzhiyunprograms whose distribution conditions are incompatible with these,
456*4882a593Smuzhiyunwrite to the author to ask for permission.  For software which is
457*4882a593Smuzhiyuncopyrighted by the Free Software Foundation, write to the Free
458*4882a593SmuzhiyunSoftware Foundation; we sometimes make exceptions for this.  Our
459*4882a593Smuzhiyundecision will be guided by the two goals of preserving the free status
460*4882a593Smuzhiyunof all derivatives of our free software and of promoting the sharing
461*4882a593Smuzhiyunand reuse of software generally.
462*4882a593Smuzhiyun
463*4882a593Smuzhiyun			    NO WARRANTY
464*4882a593Smuzhiyun
465*4882a593Smuzhiyun  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
466*4882a593SmuzhiyunWARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
467*4882a593SmuzhiyunEXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
468*4882a593SmuzhiyunOTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
469*4882a593SmuzhiyunKIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
470*4882a593SmuzhiyunIMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
471*4882a593SmuzhiyunPURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
472*4882a593SmuzhiyunLIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
473*4882a593SmuzhiyunTHE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
474*4882a593Smuzhiyun
475*4882a593Smuzhiyun  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
476*4882a593SmuzhiyunWRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
477*4882a593SmuzhiyunAND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
478*4882a593SmuzhiyunFOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
479*4882a593SmuzhiyunCONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
480*4882a593SmuzhiyunLIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
481*4882a593SmuzhiyunRENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
482*4882a593SmuzhiyunFAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF

484*4882a593SmuzhiyunDAMAGES.

487*4882a593Smuzhiyun
488*4882a593Smuzhiyun     Appendix: How to Apply These Terms to Your New Libraries
489*4882a593Smuzhiyun
490*4882a593Smuzhiyun  If you develop a new library, and you want it to be of the greatest
491*4882a593Smuzhiyunpossible use to the public, we recommend making it free software that
492*4882a593Smuzhiyuneveryone can redistribute and change.  You can do so by permitting
493*4882a593Smuzhiyunredistribution under these terms (or, alternatively, under the terms of the
494*4882a593Smuzhiyunordinary General Public License).
495*4882a593Smuzhiyun
496*4882a593Smuzhiyun  To apply these terms, attach the following notices to the library.  It is
497*4882a593Smuzhiyunsafest to attach them to the start of each source file to most effectively
498*4882a593Smuzhiyunconvey the exclusion of warranty; and each file should have at least the
499*4882a593Smuzhiyun"copyright" line and a pointer to where the full notice is found.

514*4882a593Smuzhiyun    You should have received a copy of the GNU Library General Public

519*4882a593Smuzhiyun
520*4882a593SmuzhiyunYou should also get your employer (if you work as a programmer) or your
521*4882a593Smuzhiyunschool, if any, to sign a "copyright disclaimer" for the library, if
522*4882a593Smuzhiyunnecessary.  Here is a sample; alter the names:
