 | 12 |                             Preamble
 | 
|---|
 | 13 | 
 | 
|---|
 | 14 |   The licenses for most software are designed to take away your
 | 
|---|
 | 15 | freedom to share and change it.  By contrast, the GNU General Public
 | 
|---|
 | 16 | Licenses are intended to guarantee your freedom to share and change
 | 
|---|
 | 17 | free software--to make sure the software is free for all its users.
 | 
|---|
 | 18 | 
 | 
|---|
 | 19 |   This license, the Library General Public License, applies to some
 | 
|---|
 | 20 | specially designated Free Software Foundation software, and to any
 | 
|---|
 | 21 | other libraries whose authors decide to use it.  You can use it for
 | 
|---|
 | 22 | your libraries, too.
 | 
|---|
 | 23 | 
 | 
|---|
 | 24 |   When we speak of free software, we are referring to freedom, not
 | 
|---|
 | 25 | price.  Our General Public Licenses are designed to make sure that you
 | 
|---|
 | 26 | have the freedom to distribute copies of free software (and charge for
 | 
|---|
 | 27 | this service if you wish), that you receive source code or can get it
 | 
|---|
 | 28 | if you want it, that you can change the software or use pieces of it
 | 
|---|
 | 29 | in new free programs; and that you know you can do these things.
 | 
|---|
 | 30 | 
 | 
|---|
 | 31 |   To protect your rights, we need to make restrictions that forbid
 | 
|---|
 | 32 | anyone to deny you these rights or to ask you to surrender the rights.
 | 
|---|
 | 33 | These restrictions translate to certain responsibilities for you if
 | 
|---|
 | 34 | you distribute copies of the library, or if you modify it.
 | 
|---|
 | 35 | 
 | 
|---|
 | 36 |   For example, if you distribute copies of the library, whether gratis
 | 
|---|
 | 37 | or for a fee, you must give the recipients all the rights that we gave
 | 
|---|
 | 38 | you.  You must make sure that they, too, receive or can get the source
 | 
|---|
 | 39 | code.  If you link a program with the library, you must provide
 | 
|---|
 | 40 | complete object files to the recipients so that they can relink them
 | 
|---|
 | 41 | with the library, after making changes to the library and recompiling
 | 
|---|
 | 42 | it.  And you must show them these terms so they know their rights.
 | 
|---|
 | 43 | 
 | 
|---|
 | 44 |   Our method of protecting your rights has two steps: (1) copyright
 | 
|---|
 | 45 | the library, and (2) offer you this license which gives you legal
 | 
|---|
 | 46 | permission to copy, distribute and/or modify the library.
 | 
|---|
 | 47 | 
 | 
|---|
 | 48 |   Also, for each distributor's protection, we want to make certain
 | 
|---|
 | 49 | that everyone understands that there is no warranty for this free
 | 
|---|
 | 50 | library.  If the library is modified by someone else and passed on, we
 | 
|---|
 | 51 | want its recipients to know that what they have is not the original
 | 
|---|
 | 52 | version, so that any problems introduced by others will not reflect on
 | 
|---|
 | 53 | the original authors' reputations.
 | 
|---|
 | 54 |  | 
|---|
 | 55 | 
 | 
|---|
 | 56 |   Finally, any free program is threatened constantly by software
 | 
|---|
 | 57 | patents.  We wish to avoid the danger that companies distributing free
 | 
|---|
 | 58 | software will individually obtain patent licenses, thus in effect
 | 
|---|
 | 59 | transforming the program into proprietary software.  To prevent this,
 | 
|---|
 | 60 | we have made it clear that any patent must be licensed for everyone's
 | 
|---|
 | 61 | free use or not licensed at all.
 | 
|---|
 | 62 | 
 | 
|---|
 | 63 |   Most GNU software, including some libraries, is covered by the ordinary
 | 
|---|
 | 64 | GNU General Public License, which was designed for utility programs.  This
 | 
|---|
 | 65 | license, the GNU Library General Public License, applies to certain
 | 
|---|
 | 66 | designated libraries.  This license is quite different from the ordinary
 | 
|---|
 | 67 | one; be sure to read it in full, and don't assume that anything in it is
 | 
|---|
 | 68 | the same as in the ordinary license.
 | 
|---|
 | 69 | 
 | 
|---|
 | 70 |   The reason we have a separate public license for some libraries is that
 | 
|---|
 | 71 | they blur the distinction we usually make between modifying or adding to a
 | 
|---|
 | 72 | program and simply using it.  Linking a program with a library, without
 | 
|---|
 | 73 | changing the library, is in some sense simply using the library, and is
 | 
|---|
 | 74 | analogous to running a utility program or application program.  However, in
 | 
|---|
 | 75 | a textual and legal sense, the linked executable is a combined work, a
 | 
|---|
 | 76 | derivative of the original library, and the ordinary General Public License
 | 
|---|
 | 77 | treats it as such.
 | 
|---|
 | 78 | 
 | 
|---|
 | 79 |   Because of this blurred distinction, using the ordinary General
 | 
|---|
 | 80 | Public License for libraries did not effectively promote software
 | 
|---|
 | 81 | sharing, because most developers did not use the libraries.  We
 | 
|---|
 | 82 | concluded that weaker conditions might promote sharing better.
 | 
|---|
 | 83 | 
 | 
|---|
 | 84 |   However, unrestricted linking of non-free programs would deprive the
 | 
|---|
 | 85 | users of those programs of all benefit from the free status of the
 | 
|---|
 | 86 | libraries themselves.  This Library General Public License is intended to
 | 
|---|
 | 87 | permit developers of non-free programs to use free libraries, while
 | 
|---|
 | 88 | preserving your freedom as a user of such programs to change the free
 | 
|---|
 | 89 | libraries that are incorporated in them.  (We have not seen how to achieve
 | 
|---|
 | 90 | this as regards changes in header files, but we have achieved it as regards
 | 
|---|
 | 91 | changes in the actual functions of the Library.)  The hope is that this
 | 
|---|
 | 92 | will lead to faster development of free libraries.
 | 
|---|
 | 93 | 
 | 
|---|
 | 94 |   The precise terms and conditions for copying, distribution and
 | 
|---|
 | 95 | modification follow.  Pay close attention to the difference between a
 | 
|---|
 | 96 | "work based on the library" and a "work that uses the library".  The
 | 
|---|
 | 97 | former contains code derived from the library, while the latter only
 | 
|---|
 | 98 | works together with the library.
 | 
|---|
 | 99 | 
 | 
|---|
 | 100 |   Note that it is possible for a library to be covered by the ordinary
 | 
|---|
 | 101 | General Public License rather than by this special one.
 |

|---|
 | 104 |                   GNU LIBRARY GENERAL PUBLIC LICENSE
 | 
|---|
 | 105 |    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 | 
|---|
 | 106 | 
 | 
|---|
 | 107 |   0. This License Agreement applies to any software library which
 | 
|---|
 | 108 | contains a notice placed by the copyright holder or other authorized
 | 
|---|
 | 109 | party saying it may be distributed under the terms of this Library
 | 
|---|
 | 110 | General Public License (also called "this License").  Each licensee is
 | 
|---|
 | 111 | addressed as "you".
 | 
|---|
 | 112 | 
 | 
|---|
 | 113 |   A "library" means a collection of software functions and/or data
 | 
|---|
 | 114 | prepared so as to be conveniently linked with application programs
 | 
|---|
 | 115 | (which use some of those functions and data) to form executables.
 | 
|---|
 | 116 | 
 | 
|---|
 | 117 |   The "Library", below, refers to any such software library or work
 | 
|---|
 | 118 | which has been distributed under these terms.  A "work based on the
 | 
|---|
 | 119 | Library" means either the Library or any derivative work under
 | 
|---|
 | 120 | copyright law: that is to say, a work containing the Library or a
 | 
|---|
 | 121 | portion of it, either verbatim or with modifications and/or translated
 | 
|---|
 | 122 | straightforwardly into another language.  (Hereinafter, translation is
 | 
|---|
 | 123 | included without limitation in the term "modification".)
 | 
|---|
 | 124 | 
 | 
|---|
 | 125 |   "Source code" for a work means the preferred form of the work for
 | 
|---|
 | 126 | making modifications to it.  For a library, complete source code means
 | 
|---|
 | 127 | all the source code for all modules it contains, plus any associated
 | 
|---|
 | 128 | interface definition files, plus the scripts used to control compilation
 | 
|---|
 | 129 | and installation of the library.
 | 
|---|
 | 130 | 
 | 
|---|
 | 131 |   Activities other than copying, distribution and modification are not
 | 
|---|
 | 132 | covered by this License; they are outside its scope.  The act of
 | 
|---|
 | 133 | running a program using the Library is not restricted, and output from
 | 
|---|
 | 134 | such a program is covered only if its contents constitute a work based
 | 
|---|
 | 135 | on the Library (independent of the use of the Library in a tool for
 | 
|---|
 | 136 | writing it).  Whether that is true depends on what the Library does
 | 
|---|
 | 137 | and what the program that uses the Library does.
 | 
|---|
 | 138 |   
 | 
|---|
 | 139 |   1. You may copy and distribute verbatim copies of the Library's
 | 
|---|
 | 140 | complete source code as you receive it, in any medium, provided that
 | 
|---|
 | 141 | you conspicuously and appropriately publish on each copy an
 | 
|---|
 | 142 | appropriate copyright notice and disclaimer of warranty; keep intact
 | 
|---|
 | 143 | all the notices that refer to this License and to the absence of any
 | 
|---|
 | 144 | warranty; and distribute a copy of this License along with the
 | 
|---|
 | 145 | Library.
 | 
|---|
 | 146 | 
 | 
|---|
 | 147 |   You may charge a fee for the physical act of transferring a copy,
 | 
|---|
 | 148 | and you may at your option offer warranty protection in exchange for a
 | 
|---|
 | 149 | fee.
 | 
|---|
 | 150 |  | 
|---|
 | 151 | 
 | 
|---|
 | 152 |   2. You may modify your copy or copies of the Library or any portion
 | 
|---|
 | 153 | of it, thus forming a work based on the Library, and copy and
 | 
|---|
 | 154 | distribute such modifications or work under the terms of Section 1
 | 
|---|
 | 155 | above, provided that you also meet all of these conditions:
 | 
|---|
 | 156 | 
 | 
|---|
 | 157 |     a) The modified work must itself be a software library.
 | 
|---|
 | 158 | 
 | 
|---|
 | 159 |     b) You must cause the files modified to carry prominent notices
 | 
|---|
 | 160 |     stating that you changed the files and the date of any change.
 | 
|---|
 | 161 | 
 | 
|---|
 | 162 |     c) You must cause the whole of the work to be licensed at no
 | 
|---|
 | 163 |     charge to all third parties under the terms of this License.
 | 
|---|
 | 164 | 
 | 
|---|
 | 165 |     d) If a facility in the modified Library refers to a function or a
 | 
|---|
 | 166 |     table of data to be supplied by an application program that uses
 | 
|---|
 | 167 |     the facility, other than as an argument passed when the facility
 | 
|---|
 | 168 |     is invoked, then you must make a good faith effort to ensure that,
 | 
|---|
 | 169 |     in the event an application does not supply such function or
 | 
|---|
 | 170 |     table, the facility still operates, and performs whatever part of
 | 
|---|
 | 171 |     its purpose remains meaningful.
 | 
|---|
 | 172 | 
 | 
|---|
 | 173 |     (For example, a function in a library to compute square roots has
 | 
|---|
 | 174 |     a purpose that is entirely well-defined independent of the
 | 
|---|
 | 175 |     application.  Therefore, Subsection 2d requires that any
 | 
|---|
 | 176 |     application-supplied function or table used by this function must
 | 
|---|
 | 177 |     be optional: if the application does not supply it, the square
 | 
|---|
 | 178 |     root function must still compute square roots.)
 | 
|---|
 | 179 | 
 | 
|---|
 | 180 | These requirements apply to the modified work as a whole.  If
 | 
|---|
 | 181 | identifiable sections of that work are not derived from the Library,
 | 
|---|
 | 182 | and can be reasonably considered independent and separate works in
 | 
|---|
 | 183 | themselves, then this License, and its terms, do not apply to those
 | 
|---|
 | 184 | sections when you distribute them as separate works.  But when you
 | 
|---|
 | 185 | distribute the same sections as part of a whole which is a work based
 | 
|---|
 | 186 | on the Library, the distribution of the whole must be on the terms of
 | 
|---|
 | 187 | this License, whose permissions for other licensees extend to the
 | 
|---|
 | 188 | entire whole, and thus to each and every part regardless of who wrote
 | 
|---|
 | 189 | it.
 | 
|---|
 | 190 | 
 | 
|---|
 | 191 | Thus, it is not the intent of this section to claim rights or contest
 | 
|---|
 | 192 | your rights to work written entirely by you; rather, the intent is to
 | 
|---|
 | 193 | exercise the right to control the distribution of derivative or
 | 
|---|
 | 194 | collective works based on the Library.
 | 
|---|
 | 195 | 
 | 
|---|
 | 196 | In addition, mere aggregation of another work not based on the Library
 | 
|---|
 | 197 | with the Library (or with a work based on the Library) on a volume of
 | 
|---|
 | 198 | a storage or distribution medium does not bring the other work under
 | 
|---|
 | 199 | the scope of this License.
 | 
|---|
 | 200 | 
 | 
|---|
 | 201 |   3. You may opt to apply the terms of the ordinary GNU General Public
 | 
|---|
 | 202 | License instead of this License to a given copy of the Library.  To do
 | 
|---|
 | 203 | this, you must alter all the notices that refer to this License, so
 | 
|---|
 | 204 | that they refer to the ordinary GNU General Public License, version 2,
 | 
|---|
 | 205 | instead of to this License.  (If a newer version than version 2 of the
 | 
|---|
 | 206 | ordinary GNU General Public License has appeared, then you can specify
 | 
|---|
 | 207 | that version instead if you wish.)  Do not make any other change in
 | 
|---|
 | 208 | these notices.
 | 
|---|
 | 209 |  | 
|---|
 | 210 | 
 | 
|---|
 | 211 |   Once this change is made in a given copy, it is irreversible for
 | 
|---|
 | 212 | that copy, so the ordinary GNU General Public License applies to all
 | 
|---|
 | 213 | subsequent copies and derivative works made from that copy.
 | 
|---|
 | 214 | 
 | 
|---|
 | 215 |   This option is useful when you wish to copy part of the code of
 | 
|---|
 | 216 | the Library into a program that is not a library.
 | 
|---|
 | 217 | 
 | 
|---|
 | 218 |   4. You may copy and distribute the Library (or a portion or
 | 
|---|
 | 219 | derivative of it, under Section 2) in object code or executable form
 | 
|---|
 | 220 | under the terms of Sections 1 and 2 above provided that you accompany
 | 
|---|
 | 221 | it with the complete corresponding machine-readable source code, which
 | 
|---|
 | 222 | must be distributed under the terms of Sections 1 and 2 above on a
 | 
|---|
 | 223 | medium customarily used for software interchange.
 | 
|---|
 | 224 | 
 | 
|---|
 | 225 |   If distribution of object code is made by offering access to copy
 | 
|---|
 | 226 | from a designated place, then offering equivalent access to copy the
 | 
|---|
 | 227 | source code from the same place satisfies the requirement to
 | 
|---|
 | 228 | distribute the source code, even though third parties are not
 | 
|---|
 | 229 | compelled to copy the source along with the object code.
 | 
|---|
 | 230 | 
 | 
|---|
 | 231 |   5. A program that contains no derivative of any portion of the
 | 
|---|
 | 232 | Library, but is designed to work with the Library by being compiled or
 | 
|---|
 | 233 | linked with it, is called a "work that uses the Library".  Such a
 | 
|---|
 | 234 | work, in isolation, is not a derivative work of the Library, and
 | 
|---|
 | 235 | therefore falls outside the scope of this License.
 | 
|---|
 | 236 | 
 | 
|---|
 | 237 |   However, linking a "work that uses the Library" with the Library
 | 
|---|
 | 238 | creates an executable that is a derivative of the Library (because it
 | 
|---|
 | 239 | contains portions of the Library), rather than a "work that uses the
 | 
|---|
 | 240 | library".  The executable is therefore covered by this License.
 | 
|---|
 | 241 | Section 6 states terms for distribution of such executables.
 | 
|---|
 | 242 | 
 | 
|---|
 | 243 |   When a "work that uses the Library" uses material from a header file
 | 
|---|
 | 244 | that is part of the Library, the object code for the work may be a
 | 
|---|
 | 245 | derivative work of the Library even though the source code is not.
 | 
|---|
 | 246 | Whether this is true is especially significant if the work can be
 | 
|---|
 | 247 | linked without the Library, or if the work is itself a library.  The
 | 
|---|
 | 248 | threshold for this to be true is not precisely defined by law.
 | 
|---|
 | 249 | 
 | 
|---|
 | 250 |   If such an object file uses only numerical parameters, data
 | 
|---|
 | 251 | structure layouts and accessors, and small macros and small inline
 | 
|---|
 | 252 | functions (ten lines or less in length), then the use of the object
 | 
|---|
 | 253 | file is unrestricted, regardless of whether it is legally a derivative
 | 
|---|
 | 254 | work.  (Executables containing this object code plus portions of the
 | 
|---|
 | 255 | Library will still fall under Section 6.)
 | 
|---|
 | 256 | 
 | 
|---|
 | 257 |   Otherwise, if the work is a derivative of the Library, you may
 | 
|---|
 | 258 | distribute the object code for the work under the terms of Section 6.
 | 
|---|
 | 259 | Any executables containing that work also fall under Section 6,
 | 
|---|
 | 260 | whether or not they are linked directly with the Library itself.
 | 
|---|
 | 261 |  | 
|---|
 | 262 | 
 | 
|---|
 | 263 |   6. As an exception to the Sections above, you may also compile or
 | 
|---|
 | 264 | link a "work that uses the Library" with the Library to produce a
 | 
|---|
 | 265 | work containing portions of the Library, and distribute that work
 | 
|---|
 | 266 | under terms of your choice, provided that the terms permit
 | 
|---|
 | 267 | modification of the work for the customer's own use and reverse
 | 
|---|
 | 268 | engineering for debugging such modifications.
 | 
|---|
 | 269 | 
 | 
|---|
 | 270 |   You must give prominent notice with each copy of the work that the
 | 
|---|
 | 271 | Library is used in it and that the Library and its use are covered by
 | 
|---|
 | 272 | this License.  You must supply a copy of this License.  If the work
 | 
|---|
 | 273 | during execution displays copyright notices, you must include the
 | 
|---|
 | 274 | copyright notice for the Library among them, as well as a reference
 | 
|---|
 | 275 | directing the user to the copy of this License.  Also, you must do one
 | 
|---|
 | 276 | of these things:
 | 
|---|
 | 277 | 
 | 
|---|
 | 278 |     a) Accompany the work with the complete corresponding
 | 
|---|
 | 279 |     machine-readable source code for the Library including whatever
 | 
|---|
 | 280 |     changes were used in the work (which must be distributed under
 | 
|---|
 | 281 |     Sections 1 and 2 above); and, if the work is an executable linked
 | 
|---|
 | 282 |     with the Library, with the complete machine-readable "work that
 | 
|---|
 | 283 |     uses the Library", as object code and/or source code, so that the
 | 
|---|
 | 284 |     user can modify the Library and then relink to produce a modified
 | 
|---|
 | 285 |     executable containing the modified Library.  (It is understood
 | 
|---|
 | 286 |     that the user who changes the contents of definitions files in the
 | 
|---|
 | 287 |     Library will not necessarily be able to recompile the application
 | 
|---|
 | 288 |     to use the modified definitions.)
 | 
|---|
 | 289 | 
 | 
|---|
 | 290 |     b) Accompany the work with a written offer, valid for at
 | 
|---|
 | 291 |     least three years, to give the same user the materials
 | 
|---|
 | 292 |     specified in Subsection 6a, above, for a charge no more
 | 
|---|
 | 293 |     than the cost of performing this distribution.
 | 
|---|
 | 294 | 
 | 
|---|
 | 295 |     c) If distribution of the work is made by offering access to copy
 | 
|---|
 | 296 |     from a designated place, offer equivalent access to copy the above
 | 
|---|
 | 297 |     specified materials from the same place.
 | 
|---|
 | 298 | 
 | 
|---|
 | 299 |     d) Verify that the user has already received a copy of these
 | 
|---|
 | 300 |     materials or that you have already sent this user a copy.
 | 
|---|
 | 301 | 
 | 
|---|
 | 302 |   For an executable, the required form of the "work that uses the
 | 
|---|
 | 303 | Library" must include any data and utility programs needed for
 | 
|---|
 | 304 | reproducing the executable from it.  However, as a special exception,
 | 
|---|
 | 305 | the source code distributed need not include anything that is normally
 | 
|---|
 | 306 | distributed (in either source or binary form) with the major
 | 
|---|
 | 307 | components (compiler, kernel, and so on) of the operating system on
 | 
|---|
 | 308 | which the executable runs, unless that component itself accompanies
 | 
|---|
 | 309 | the executable.
 | 
|---|
 | 310 | 
 | 
|---|
 | 311 |   It may happen that this requirement contradicts the license
 | 
|---|
 | 312 | restrictions of other proprietary libraries that do not normally
 | 
|---|
 | 313 | accompany the operating system.  Such a contradiction means you cannot
 | 
|---|
 | 314 | use both them and the Library together in an executable that you
 | 
|---|
 | 315 | distribute.
 | 
|---|
 | 316 |  | 
|---|
 | 317 | 
 | 
|---|
 | 318 |   7. You may place library facilities that are a work based on the
 | 
|---|
 | 319 | Library side-by-side in a single library together with other library
 | 
|---|
 | 320 | facilities not covered by this License, and distribute such a combined
 | 
|---|
 | 321 | library, provided that the separate distribution of the work based on
 | 
|---|
 | 322 | the Library and of the other library facilities is otherwise
 | 
|---|
 | 323 | permitted, and provided that you do these two things:
 | 
|---|
 | 324 | 
 | 
|---|
 | 325 |     a) Accompany the combined library with a copy of the same work
 | 
|---|
 | 326 |     based on the Library, uncombined with any other library
 | 
|---|
 | 327 |     facilities.  This must be distributed under the terms of the
 | 
|---|
 | 328 |     Sections above.
 | 
|---|
 | 329 | 
 | 
|---|
 | 330 |     b) Give prominent notice with the combined library of the fact
 | 
|---|
 | 331 |     that part of it is a work based on the Library, and explaining
 | 
|---|
 | 332 |     where to find the accompanying uncombined form of the same work.
 | 
|---|
 | 333 | 
 | 
|---|
 | 334 |   8. You may not copy, modify, sublicense, link with, or distribute
 | 
|---|
 | 335 | the Library except as expressly provided under this License.  Any
 | 
|---|
 | 336 | attempt otherwise to copy, modify, sublicense, link with, or
 | 
|---|
 | 337 | distribute the Library is void, and will automatically terminate your
 | 
|---|
 | 338 | rights under this License.  However, parties who have received copies,
 | 
|---|
 | 339 | or rights, from you under this License will not have their licenses
 | 
|---|
 | 340 | terminated so long as such parties remain in full compliance.
 | 
|---|
 | 341 | 
 | 
|---|
 | 342 |   9. You are not required to accept this License, since you have not
 | 
|---|
 | 343 | signed it.  However, nothing else grants you permission to modify or
 | 
|---|
 | 344 | distribute the Library or its derivative works.  These actions are
 | 
|---|
 | 345 | prohibited by law if you do not accept this License.  Therefore, by
 | 
|---|
 | 346 | modifying or distributing the Library (or any work based on the
 | 
|---|
 | 347 | Library), you indicate your acceptance of this License to do so, and
 | 
|---|
 | 348 | all its terms and conditions for copying, distributing or modifying
 | 
|---|
 | 349 | the Library or works based on it.
 | 
|---|
 | 350 | 
 | 
|---|
 | 351 |   10. Each time you redistribute the Library (or any work based on the
 | 
|---|
 | 352 | Library), the recipient automatically receives a license from the
 | 
|---|
 | 353 | original licensor to copy, distribute, link with or modify the Library
 | 
|---|
 | 354 | subject to these terms and conditions.  You may not impose any further
 | 
|---|
 | 355 | restrictions on the recipients' exercise of the rights granted herein.
 | 
|---|
 | 356 | You are not responsible for enforcing compliance by third parties to
 | 
|---|
 | 357 | this License.
 | 
|---|
 | 358 |  | 
|---|
 | 359 | 
 | 
|---|
 | 360 |   11. If, as a consequence of a court judgment or allegation of patent
 | 
|---|
 | 361 | infringement or for any other reason (not limited to patent issues),
 | 
|---|
 | 362 | conditions are imposed on you (whether by court order, agreement or
 | 
|---|
 | 363 | otherwise) that contradict the conditions of this License, they do not
 | 
|---|
 | 364 | excuse you from the conditions of this License.  If you cannot
 | 
|---|
 | 365 | distribute so as to satisfy simultaneously your obligations under this
 | 
|---|
 | 366 | License and any other pertinent obligations, then as a consequence you
 | 
|---|
 | 367 | may not distribute the Library at all.  For example, if a patent
 | 
|---|
 | 368 | license would not permit royalty-free redistribution of the Library by
 | 
|---|
 | 369 | all those who receive copies directly or indirectly through you, then
 | 
|---|
 | 370 | the only way you could satisfy both it and this License would be to
 | 
|---|
 | 371 | refrain entirely from distribution of the Library.
 | 
|---|
 | 372 | 
 | 
|---|
 | 373 | If any portion of this section is held invalid or unenforceable under any
 | 
|---|
 | 374 | particular circumstance, the balance of the section is intended to apply,
 | 
|---|
 | 375 | and the section as a whole is intended to apply in other circumstances.
 | 
|---|
 | 376 | 
 | 
|---|
 | 377 | It is not the purpose of this section to induce you to infringe any
 | 
|---|
 | 378 | patents or other property right claims or to contest validity of any
 | 
|---|
 | 379 | such claims; this section has the sole purpose of protecting the
 | 
|---|
 | 380 | integrity of the free software distribution system which is
 | 
|---|
 | 381 | implemented by public license practices.  Many people have made
 | 
|---|
 | 382 | generous contributions to the wide range of software distributed
 | 
|---|
 | 383 | through that system in reliance on consistent application of that
 | 
|---|
 | 384 | system; it is up to the author/donor to decide if he or she is willing
 | 
|---|
 | 385 | to distribute software through any other system and a licensee cannot
 | 
|---|
 | 386 | impose that choice.
 | 
|---|
 | 387 | 
 | 
|---|
 | 388 | This section is intended to make thoroughly clear what is believed to
 | 
|---|
 | 389 | be a consequence of the rest of this License.
 | 
|---|
 | 390 | 
 | 
|---|
 | 391 |   12. If the distribution and/or use of the Library is restricted in
 | 
|---|
 | 392 | certain countries either by patents or by copyrighted interfaces, the
 | 
|---|
 | 393 | original copyright holder who places the Library under this License may add
 | 
|---|
 | 394 | an explicit geographical distribution limitation excluding those countries,
 | 
|---|
 | 395 | so that distribution is permitted only in or among countries not thus
 | 
|---|
 | 396 | excluded.  In such case, this License incorporates the limitation as if
 | 
|---|
 | 397 | written in the body of this License.
 | 
|---|
 | 398 | 
 | 
|---|
 | 399 |   13. The Free Software Foundation may publish revised and/or new
 | 
|---|
 | 400 | versions of the Library General Public License from time to time.
 | 
|---|
 | 401 | Such new versions will be similar in spirit to the present version,
 | 
|---|
 | 402 | but may differ in detail to address new problems or concerns.
 | 
|---|
 | 403 | 
 | 
|---|
 | 404 | Each version is given a distinguishing version number.  If the Library
 | 
|---|
 | 405 | specifies a version number of this License which applies to it and
 | 
|---|
 | 406 | "any later version", you have the option of following the terms and
 | 
|---|
 | 407 | conditions either of that version or of any later version published by
 | 
|---|
 | 408 | the Free Software Foundation.  If the Library does not specify a
 | 
|---|
 | 409 | license version number, you may choose any version ever published by
 | 
|---|
 | 410 | the Free Software Foundation.
 | 
|---|
 | 411 |  | 
|---|
 | 412 | 
 | 
|---|
 | 413 |   14. If you wish to incorporate parts of the Library into other free
 | 
|---|
 | 414 | programs whose distribution conditions are incompatible with these,
 | 
|---|
 | 415 | write to the author to ask for permission.  For software which is
 | 
|---|
 | 416 | copyrighted by the Free Software Foundation, write to the Free
 | 
|---|
 | 417 | Software Foundation; we sometimes make exceptions for this.  Our
 | 
|---|
 | 418 | decision will be guided by the two goals of preserving the free status
 | 
|---|
 | 419 | of all derivatives of our free software and of promoting the sharing
 | 
|---|
 | 420 | and reuse of software generally.
 | 
|---|
 | 421 | 
 | 
|---|
 | 422 |                             NO WARRANTY
 | 
|---|
 | 423 | 
 | 
|---|
 | 424 |   15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
 | 
|---|
 | 425 | WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
 | 
|---|
 | 426 | EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
 | 
|---|
 | 427 | OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
 | 
|---|
 | 428 | KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
 | 
|---|
 | 429 | IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 | 
|---|
 | 430 | PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
 | 
|---|
 | 431 | LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
 | 
|---|
 | 432 | THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
 | 
|---|
 | 433 | 
 | 
|---|
 | 434 |   16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
 | 
|---|
 | 435 | WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
 | 
|---|
 | 436 | AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
 | 
|---|
 | 437 | FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
 | 
|---|
 | 438 | CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
 | 
|---|
 | 439 | LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
 | 
|---|
 | 440 | RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
 | 
|---|
 | 441 | FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
 | 
|---|
 | 442 | SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
 | 
|---|
 | 443 | DAMAGES.
 | 
|---|
 | 444 |

 | 
|---|
 | 448 |      Appendix: How to Apply These Terms to Your New Libraries
 | 
|---|
 | 449 | 
 | 
|---|
 | 450 |   If you develop a new library, and you want it to be of the greatest
 | 
|---|
 | 451 | possible use to the public, we recommend making it free software that
 | 
|---|
 | 452 | everyone can redistribute and change.  You can do so by permitting
 | 
|---|
 | 453 | redistribution under these terms (or, alternatively, under the terms of the
 | 
|---|
 | 454 | ordinary General Public License).
 | 
|---|
 | 455 | 
 | 
|---|
 | 456 |   To apply these terms, attach the following notices to the library.  It is
 | 
|---|
 | 457 | safest to attach them to the start of each source file to most effectively
 | 
|---|
 | 458 | convey the exclusion of warranty; and each file should have at least the
 | 
|---|
 | 459 | "copyright" line and a pointer to where the full notice is found.
 | 
|---|
 | 460 | 
 | 
|---|
 | 461 |     <one line to give the library's name and a brief idea of what it does.>
 | 
|---|
 | 462 |     Copyright (C) <year>  <name of author>
 | 
|---|
 | 463 | 
 | 
|---|
 | 464 |     This library is free software; you can redistribute it and/or
 | 
|---|
 | 465 |     modify it under the terms of the GNU Library General Public
 | 
|---|
 | 466 |     License as published by the Free Software Foundation; either
 | 
|---|
 | 467 |     version 2 of the License, or (at your option) any later version.
 | 
|---|
 | 468 | 
 | 
|---|
 | 469 |     This library is distributed in the hope that it will be useful,
 | 
|---|
 | 470 |     but WITHOUT ANY WARRANTY; without even the implied warranty of
 |

 | 471 |     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU

|---|
 | 472 |     Library General Public License for more details.
 | 
|---|
 | 473 | 
 | 
|---|
 | 474 |     You should have received a copy of the GNU Library General Public
 | 
|---|
 | 475 |     License along with this library; if not, write to the Free

 | 
|---|
 | 477 | 
 | 
|---|
 | 478 | Also add information on how to contact you by electronic and paper mail.
 | 
|---|
 | 479 | 
 | 
|---|
 | 480 | You should also get your employer (if you work as a programmer) or your
 | 
|---|
 | 481 | school, if any, to sign a "copyright disclaimer" for the library, if
 | 
|---|
 | 482 | necessary.  Here is a sample; alter the names:
