|---|
| 10 | | The licenses for most software are designed to take away your freedom to |
|---|
| 11 | | share and change it. By contrast, the GNU General Public Licenses are |
|---|
| 12 | | intended to guarantee your freedom to share and change free software--to |
|---|
| 13 | | make sure the software is free for all its users. |
|---|
| 14 | | |
|---|
| 15 | | This license, the Lesser General Public License, applies to some specially |
|---|
| 16 | | designated software packages--typically libraries--of the Free Software |
|---|
| 17 | | Foundation and other authors who decide to use it. You can use it too, but |
|---|
| 18 | | we suggest you first think carefully about whether this license or the |
|---|
| 19 | | ordinary General Public License is the better strategy to use in any |
|---|
| 20 | | particular case, based on the explanations below. |
|---|
| 21 | | |
|---|
| 22 | | When we speak of free software, we are referring to freedom of use, not |
|---|
| 23 | | price. Our General Public Licenses are designed to make sure that you have |
|---|
| 24 | | the freedom to distribute copies of free software (and charge for this |
|---|
| 25 | | service if you wish); that you receive source code or can get it if you |
|---|
| 26 | | want it; that you can change the software and use pieces of it in new free |
|---|
| 27 | | programs; and that you are informed that you can do these things. |
|---|
| 28 | | |
|---|
| 29 | | To protect your rights, we need to make restrictions that forbid |
|---|
| 30 | | distributors to deny you these rights or to ask you to surrender these |
|---|
| 31 | | rights. These restrictions translate to certain responsibilities for you |
|---|
| 32 | | if you distribute copies of the library or if you modify it. |
|---|
| 33 | | |
|---|
| 34 | | For example, if you distribute copies of the library, whether gratis or |
|---|
| 35 | | for a fee, you must give the recipients all the rights that we gave you. |
|---|
| 36 | | You must make sure that they, too, receive or can get the source code. If |
|---|
| 37 | | you link other code with the library, you must provide complete object |
|---|
| 38 | | files to the recipients, so that they can relink them with the library |
|---|
| 39 | | after making changes to the library and recompiling it. And you must show |
|---|
| 40 | | them these terms so they know their rights. |
|---|
| 41 | | |
|---|
| 42 | | We protect your rights with a two-step method: (1) we copyright the |
|---|
| 43 | | library, and (2) we offer you this license, which gives you legal |

|---|
| | 88 | Preamble |
|---|
| | 89 | |
|---|
| | 90 | The licenses for most software are designed to take away your |
|---|
| | 91 | freedom to share and change it. By contrast, the GNU General Public |
|---|
| | 92 | Licenses are intended to guarantee your freedom to share and change |
|---|
| | 93 | free software--to make sure the software is free for all its users. |
|---|
| | 94 | |
|---|
| | 95 | This license, the Lesser General Public License, applies to some |
|---|
| | 96 | specially designated software packages--typically libraries--of the |
|---|
| | 97 | Free Software Foundation and other authors who decide to use it. You |
|---|
| | 98 | can use it too, but we suggest you first think carefully about whether |
|---|
| | 99 | this license or the ordinary General Public License is the better |
|---|
| | 100 | strategy to use in any particular case, based on the explanations below. |
|---|
| | 101 | |
|---|
| | 102 | When we speak of free software, we are referring to freedom of use, |
|---|
| | 103 | not price. Our General Public Licenses are designed to make sure that |
|---|
| | 104 | you have the freedom to distribute copies of free software (and charge |
|---|
| | 105 | for this service if you wish); that you receive source code or can get |
|---|
| | 106 | it if you want it; that you can change the software and use pieces of |
|---|
| | 107 | it in new free programs; and that you are informed that you can do |
|---|
| | 108 | these things. |
|---|
| | 109 | |
|---|
| | 110 | To protect your rights, we need to make restrictions that forbid |
|---|
| | 111 | distributors to deny you these rights or to ask you to surrender these |
|---|
| | 112 | rights. These restrictions translate to certain responsibilities for |
|---|
| | 113 | you if you distribute copies of the library or if you modify it. |
|---|
| | 114 | |
|---|
| | 115 | For example, if you distribute copies of the library, whether gratis |
|---|
| | 116 | or for a fee, you must give the recipients all the rights that we gave |
|---|
| | 117 | you. You must make sure that they, too, receive or can get the source |
|---|
| | 118 | code. If you link other code with the library, you must provide |
|---|
| | 119 | complete object files to the recipients, so that they can relink them |
|---|
| | 120 | with the library after making changes to the library and recompiling |
|---|
| | 121 | it. And you must show them these terms so they know their rights. |
|---|
| | 122 | |
|---|
| | 123 | We protect your rights with a two-step method: (1) we copyright the |
|---|
| | 124 | library, and (2) we offer you this license, which gives you legal |
|---|
| 46 | | To protect each distributor, we want to make it very clear that there is |
|---|
| 47 | | no warranty for the free library. Also, if the library is modified by |
|---|
| 48 | | someone else and passed on, the recipients should know that what they have |
|---|
| 49 | | is not the original version, so that the original author's reputation will |
|---|
| 50 | | not be affected by problems that might be introduced by others. |
|---|
| 51 | | |
|---|
| 52 | | Finally, software patents pose a constant threat to the existence of any |
|---|
| 53 | | free program. We wish to make sure that a company cannot effectively |
|---|
| 54 | | restrict the users of a free program by obtaining a restrictive license |
|---|
| 55 | | from a patent holder. Therefore, we insist that any patent license |
|---|
| 56 | | obtained for a version of the library must be consistent with the full |
|---|
| 57 | | freedom of use specified in this license. |
|---|
| 58 | | |
|---|
| 59 | | Most GNU software, including some libraries, is covered by the ordinary |
|---|
| 60 | | GNU General Public License. This license, the GNU Lesser General Public |
|---|
| 61 | | License, applies to certain designated libraries, and is quite different |
|---|
| 62 | | from the ordinary General Public License. We use this license for certain |
|---|
| 63 | | libraries in order to permit linking those libraries into non-free |
|---|
| 64 | | programs. |
|---|
| 65 | | |
|---|
| 66 | | When a program is linked with a library, whether statically or using a |
|---|
| 67 | | shared library, the combination of the two is legally speaking a combined |
|---|
| 68 | | work, a derivative of the original library. The ordinary General Public |
|---|
| 69 | | License therefore permits such linking only if the entire combination fits |
|---|
| 70 | | its criteria of freedom. The Lesser General Public License permits more |
|---|
| 71 | | lax criteria for linking other code with the library. |
|---|
| 72 | | |
|---|
| 73 | | We call this license the "Lesser" General Public License because it does |
|---|
| 74 | | Less to protect the user's freedom than the ordinary General Public |
|---|
| 75 | | License. It also provides other free software developers Less of an |
|---|
| 76 | | advantage over competing non-free programs. These disadvantages are the |
|---|
| 77 | | reason we use the ordinary General Public License for many libraries. |
|---|
| 78 | | However, the Lesser license provides advantages in certain special |
|---|
| 79 | | circumstances. |
|---|
| 80 | | |
|---|
| 81 | | For example, on rare occasions, there may be a special need to encourage |
|---|
| 82 | | the widest possible use of a certain library, so that it becomes a |
|---|
| 83 | | de-facto standard. To achieve this, non-free programs must be allowed to |
|---|
| 84 | | use the library. A more frequent case is that a free library does the same |
|---|
| 85 | | job as widely used non-free libraries. In this case, there is little to |
|---|
| 86 | | gain by limiting the free library to free software only, so we use the |
|---|
| 87 | | Lesser General Public License. |
|---|
| 88 | | |
|---|
| 89 | | In other cases, permission to use a particular library in non-free |
|---|
| 90 | | programs enables a greater number of people to use a large body of free |
|---|
| 91 | | software. For example, permission to use the GNU C Library in non-free |
|---|
| 92 | | programs enables many more people to use the whole GNU operating system, |
|---|
| 93 | | as well as its variant, the GNU/Linux operating system. |
|---|
| 94 | | |
|---|
| 95 | | Although the Lesser General Public License is Less protective of the |
|---|
| 96 | | users' freedom, it does ensure that the user of a program that is linked |
|---|
| 97 | | with the Library has the freedom and the wherewithal to run that program |
|---|
| 98 | | using a modified version of the Library. |
|---|
| 99 | | |
|---|
| 100 | | The precise terms and conditions for copying, distribution and |
|---|
| 101 | | modification follow. Pay close attention to the difference between a "work |
|---|
| 102 | | based on the library" and a "work that uses the library". The former |
|---|
| 103 | | contains code derived from the library, whereas the latter must be |
|---|
| 104 | | combined with the library in order to run. |
|---|
| 105 | | |
|---|
| 106 | | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
|---|
| 107 | | |
|---|
| 108 | | 0. This License Agreement applies to any software library or other program |
|---|
| 109 | | which contains a notice placed by the copyright holder or other authorized |
|---|
| 110 | | party saying it may be distributed under the terms of this Lesser General |
|---|
| 111 | | Public License (also called "this License"). Each licensee is addressed as |
|---|
| 112 | | "you". |
|---|
| 113 | | |
|---|
| 114 | | A "library" means a collection of software functions and/or data prepared |
|---|
| 115 | | so as to be conveniently linked with application programs (which use some |
|---|
| 116 | | of those functions and data) to form executables. |
|---|
| 117 | | |
|---|
| 118 | | The "Library", below, refers to any such software library or work which |
|---|
| 119 | | has been distributed under these terms. A "work based on the Library" |
|---|
| 120 | | means either the Library or any derivative work under copyright law: that |
|---|
| 121 | | is to say, a work containing the Library or a portion of it, either |
|---|
| 122 | | verbatim or with modifications and/or translated straightforwardly into |
|---|
| 123 | | another language. (Hereinafter, translation is included without limitation |
|---|
| 124 | | in the term "modification".) |
|---|
| 125 | | |
|---|
| 126 | | "Source code" for a work means the preferred form of the work for making |
|---|
| 127 | | modifications to it. For a library, complete source code means all the |
|---|
| 128 | | source code for all modules it contains, plus any associated interface |
|---|
| 129 | | definition files, plus the scripts used to control compilation and |
|---|
| 130 | | installation of the library. |
|---|
| 131 | | |
|---|
| 132 | | Activities other than copying, distribution and modification are not |
|---|
| 133 | | covered by this License; they are outside its scope. The act of running a |
|---|
| 134 | | program using the Library is not restricted, and output from such a |
|---|
| 135 | | program is covered only if its contents constitute a work based on the |
|---|
| 136 | | Library (independent of the use of the Library in a tool for writing it). |
|---|
| 137 | | Whether that is true depends on what the Library does and what the program |
|---|
| 138 | | that uses the Library does. |
|---|
| 139 | | |
|---|
| 140 | | 1. You may copy and distribute verbatim copies of the Library's complete |
|---|
| 141 | | source code as you receive it, in any medium, provided that you |
|---|
| 142 | | conspicuously and appropriately publish on each copy an appropriate |
|---|
| 143 | | copyright notice and disclaimer of warranty; keep intact all the notices |
|---|
| 144 | | that refer to this License and to the absence of any warranty; and |
|---|
| 145 | | distribute a copy of this License along with the Library. |
|---|
| 146 | | |
|---|
| 147 | | You may charge a fee for the physical act of transferring a copy, and you |
|---|
| 148 | | may at your option offer warranty protection in exchange for a fee. |
|---|
| 149 | | |
|---|
| 150 | | 2. You may modify your copy or copies of the Library or any portion of it, |
|---|
| 151 | | thus forming a work based on the Library, and copy and distribute such |
|---|
| 152 | | modifications or work under the terms of Section 1 above, provided that |
|---|
| 153 | | you also meet all of these conditions: |
|---|
| 154 | | |
|---|
| 155 | | * a) The modified work must itself be a software library. |
|---|
| 156 | | * b) You must cause the files modified to carry prominent notices |
|---|
| 157 | | stating that you changed the files and the date of any change. |
|---|
| 158 | | * c) You must cause the whole of the work to be licensed at no charge |
|---|
| 159 | | to all third parties under the terms of this License. |
|---|
| 160 | | * d) If a facility in the modified Library refers to a function or a |
|---|
| 161 | | table of data to be supplied by an application program that uses the |
|---|
| 162 | | facility, other than as an argument passed when the facility is invoked, |
|---|
| 163 | | then you must make a good faith effort to ensure that, in the event an |
|---|
| 164 | | application does not supply such function or table, the facility still |
|---|
| 165 | | operates, and performs whatever part of its purpose remains meaningful. |
|---|
| 166 | | |
|---|
| 167 | | (For example, a function in a library to compute square roots has a |
|---|
| 168 | | purpose that is entirely well-defined independent of the application. |
|---|
| 169 | | Therefore, Subsection 2d requires that any application-supplied function |
|---|
| 170 | | or table used by this function must be optional: if the application does |
|---|
| 171 | | not supply it, the square root function must still compute square roots.) |
|---|
| 172 | | |
|---|
| 173 | | These requirements apply to the modified work as a whole. If |
|---|
| 174 | | identifiable sections of that work are not derived from the Library, and |
|---|
| 175 | | can be reasonably considered independent and separate works in themselves, |
|---|
| 176 | | then this License, and its terms, do not apply to those sections when you |
|---|
| 177 | | distribute them as separate works. But when you distribute the same |
|---|
| 178 | | sections as part of a whole which is a work based on the Library, the |
|---|
| 179 | | distribution of the whole must be on the terms of this License, whose |
|---|
| 180 | | permissions for other licensees extend to the entire whole, and thus to |
|---|
| 181 | | each and every part regardless of who wrote it. |
|---|
| 182 | | |
|---|
| 183 | | Thus, it is not the intent of this section to claim rights or |
|---|
| 184 | | contest your rights to work written entirely by you; rather, the intent is |
|---|
| 185 | | to exercise the right to control the distribution of derivative or |
|---|
| | 127 | To protect each distributor, we want to make it very clear that |
|---|
| | 128 | there is no warranty for the free library. Also, if the library is |
|---|
| | 129 | modified by someone else and passed on, the recipients should know |
|---|
| | 130 | that what they have is not the original version, so that the original |
|---|
| | 131 | author's reputation will not be affected by problems that might be |
|---|
| | 132 | introduced by others. |
|---|
| | 133 | |
|---|
| | 134 | Finally, software patents pose a constant threat to the existence of |
|---|
| | 135 | any free program. We wish to make sure that a company cannot |
|---|
| | 136 | effectively restrict the users of a free program by obtaining a |
|---|
| | 137 | restrictive license from a patent holder. Therefore, we insist that |
|---|
| | 138 | any patent license obtained for a version of the library must be |
|---|
| | 139 | consistent with the full freedom of use specified in this license. |
|---|
| | 140 | |
|---|
| | 141 | Most GNU software, including some libraries, is covered by the |
|---|
| | 142 | ordinary GNU General Public License. This license, the GNU Lesser |
|---|
| | 143 | General Public License, applies to certain designated libraries, and |
|---|
| | 144 | is quite different from the ordinary General Public License. We use |
|---|
| | 145 | this license for certain libraries in order to permit linking those |
|---|
| | 146 | libraries into non-free programs. |
|---|
| | 147 | |
|---|
| | 148 | When a program is linked with a library, whether statically or using |
|---|
| | 149 | a shared library, the combination of the two is legally speaking a |
|---|
| | 150 | combined work, a derivative of the original library. The ordinary |
|---|
| | 151 | General Public License therefore permits such linking only if the |
|---|
| | 152 | entire combination fits its criteria of freedom. The Lesser General |
|---|
| | 153 | Public License permits more lax criteria for linking other code with |
|---|
| | 154 | the library. |
|---|
| | 155 | |
|---|
| | 156 | We call this license the "Lesser" General Public License because it |
|---|
| | 157 | does Less to protect the user's freedom than the ordinary General |
|---|
| | 158 | Public License. It also provides other free software developers Less |
|---|
| | 159 | of an advantage over competing non-free programs. These disadvantages |
|---|
| | 160 | are the reason we use the ordinary General Public License for many |
|---|
| | 161 | libraries. However, the Lesser license provides advantages in certain |
|---|
| | 162 | special circumstances. |
|---|
| | 163 | |
|---|
| | 164 | For example, on rare occasions, there may be a special need to |
|---|
| | 165 | encourage the widest possible use of a certain library, so that it becomes |
|---|
| | 166 | a de-facto standard. To achieve this, non-free programs must be |
|---|
| | 167 | allowed to use the library. A more frequent case is that a free |
|---|
| | 168 | library does the same job as widely used non-free libraries. In this |
|---|
| | 169 | case, there is little to gain by limiting the free library to free |
|---|
| | 170 | software only, so we use the Lesser General Public License. |
|---|
| | 171 | |
|---|
| | 172 | In other cases, permission to use a particular library in non-free |
|---|
| | 173 | programs enables a greater number of people to use a large body of |
|---|
| | 174 | free software. For example, permission to use the GNU C Library in |
|---|
| | 175 | non-free programs enables many more people to use the whole GNU |
|---|
| | 176 | operating system, as well as its variant, the GNU/Linux operating |
|---|
| | 177 | system. |
|---|
| | 178 | |
|---|
| | 179 | Although the Lesser General Public License is Less protective of the |
|---|
| | 180 | users' freedom, it does ensure that the user of a program that is |
|---|
| | 181 | linked with the Library has the freedom and the wherewithal to run |
|---|
| | 182 | that program using a modified version of the Library. |
|---|
| | 183 | |
|---|
| | 184 | The precise terms and conditions for copying, distribution and |
|---|
| | 185 | modification follow. Pay close attention to the difference between a |
|---|
| | 186 | "work based on the library" and a "work that uses the library". The |
|---|
| | 187 | former contains code derived from the library, whereas the latter must |
|---|
| | 188 | be combined with the library in order to run. |
|---|
| | 189 | |
|---|
| | 190 | GNU LESSER GENERAL PUBLIC LICENSE |
|---|
| | 191 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
|---|
| | 192 | |
|---|
| | 193 | 0. This License Agreement applies to any software library or other |
|---|
| | 194 | program which contains a notice placed by the copyright holder or |
|---|
| | 195 | other authorized party saying it may be distributed under the terms of |
|---|
| | 196 | this Lesser General Public License (also called "this License"). |
|---|
| | 197 | Each licensee is addressed as "you". |
|---|
| | 198 | |
|---|
| | 199 | A "library" means a collection of software functions and/or data |
|---|
| | 200 | prepared so as to be conveniently linked with application programs |
|---|
| | 201 | (which use some of those functions and data) to form executables. |
|---|
| | 202 | |
|---|
| | 203 | The "Library", below, refers to any such software library or work |
|---|
| | 204 | which has been distributed under these terms. A "work based on the |
|---|
| | 205 | Library" means either the Library or any derivative work under |
|---|
| | 206 | copyright law: that is to say, a work containing the Library or a |
|---|
| | 207 | portion of it, either verbatim or with modifications and/or translated |
|---|
| | 208 | straightforwardly into another language. (Hereinafter, translation is |
|---|
| | 209 | included without limitation in the term "modification".) |
|---|
| | 210 | |
|---|
| | 211 | "Source code" for a work means the preferred form of the work for |
|---|
| | 212 | making modifications to it. For a library, complete source code means |
|---|
| | 213 | all the source code for all modules it contains, plus any associated |
|---|
| | 214 | interface definition files, plus the scripts used to control compilation |
|---|
| | 215 | and installation of the library. |
|---|
| | 216 | |
|---|
| | 217 | Activities other than copying, distribution and modification are not |
|---|
| | 218 | covered by this License; they are outside its scope. The act of |
|---|
| | 219 | running a program using the Library is not restricted, and output from |
|---|
| | 220 | such a program is covered only if its contents constitute a work based |
|---|
| | 221 | on the Library (independent of the use of the Library in a tool for |
|---|
| | 222 | writing it). Whether that is true depends on what the Library does |
|---|
| | 223 | and what the program that uses the Library does. |
|---|
| | 224 | |
|---|
| | 225 | 1. You may copy and distribute verbatim copies of the Library's |
|---|
| | 226 | complete source code as you receive it, in any medium, provided that |
|---|
| | 227 | you conspicuously and appropriately publish on each copy an |
|---|
| | 228 | appropriate copyright notice and disclaimer of warranty; keep intact |
|---|
| | 229 | all the notices that refer to this License and to the absence of any |
|---|
| | 230 | warranty; and distribute a copy of this License along with the |
|---|
| | 231 | Library. |
|---|
| | 232 | |
|---|
| | 233 | You may charge a fee for the physical act of transferring a copy, |
|---|
| | 234 | and you may at your option offer warranty protection in exchange for a |
|---|
| | 235 | fee. |
|---|
| | 236 | |
|---|
| | 237 | 2. You may modify your copy or copies of the Library or any portion |
|---|
| | 238 | of it, thus forming a work based on the Library, and copy and |
|---|
| | 239 | distribute such modifications or work under the terms of Section 1 |
|---|
| | 240 | above, provided that you also meet all of these conditions: |
|---|
| | 241 | |
|---|
| | 242 | a) The modified work must itself be a software library. |
|---|
| | 243 | |
|---|
| | 244 | b) You must cause the files modified to carry prominent notices |
|---|
| | 245 | stating that you changed the files and the date of any change. |
|---|
| | 246 | |
|---|
| | 247 | c) You must cause the whole of the work to be licensed at no |
|---|
| | 248 | charge to all third parties under the terms of this License. |
|---|
| | 249 | |
|---|
| | 250 | d) If a facility in the modified Library refers to a function or a |
|---|
| | 251 | table of data to be supplied by an application program that uses |
|---|
| | 252 | the facility, other than as an argument passed when the facility |
|---|
| | 253 | is invoked, then you must make a good faith effort to ensure that, |
|---|
| | 254 | in the event an application does not supply such function or |
|---|
| | 255 | table, the facility still operates, and performs whatever part of |
|---|
| | 256 | its purpose remains meaningful. |
|---|
| | 257 | |
|---|
| | 258 | (For example, a function in a library to compute square roots has |
|---|
| | 259 | a purpose that is entirely well-defined independent of the |
|---|
| | 260 | application. Therefore, Subsection 2d requires that any |
|---|
| | 261 | application-supplied function or table used by this function must |
|---|
| | 262 | be optional: if the application does not supply it, the square |
|---|
| | 263 | root function must still compute square roots.) |
|---|
| | 264 | |
|---|
| | 265 | These requirements apply to the modified work as a whole. If |
|---|
| | 266 | identifiable sections of that work are not derived from the Library, |
|---|
| | 267 | and can be reasonably considered independent and separate works in |
|---|
| | 268 | themselves, then this License, and its terms, do not apply to those |
|---|
| | 269 | sections when you distribute them as separate works. But when you |
|---|
| | 270 | distribute the same sections as part of a whole which is a work based |
|---|
| | 271 | on the Library, the distribution of the whole must be on the terms of |
|---|
| | 272 | this License, whose permissions for other licensees extend to the |
|---|
| | 273 | entire whole, and thus to each and every part regardless of who wrote |
|---|
| | 274 | it. |
|---|
| | 275 | |
|---|
| | 276 | Thus, it is not the intent of this section to claim rights or contest |
|---|
| | 277 | your rights to work written entirely by you; rather, the intent is to |
|---|
| | 278 | exercise the right to control the distribution of derivative or |
|---|
| 188 | | In addition, mere aggregation of another work not based on the Library |
|---|
| 189 | | with the Library (or with a work based on the Library) on a volume of a |
|---|
| 190 | | storage or distribution medium does not bring the other work under the |
|---|
| 191 | | scope of this License. |
|---|
| 192 | | |
|---|
| 193 | | 3. You may opt to apply the terms of the ordinary GNU General Public |
|---|
| 194 | | License instead of this License to a given copy of the Library. To do |
|---|
| 195 | | this, you must alter all the notices that refer to this License, so that |
|---|
| 196 | | they refer to the ordinary GNU General Public License, version 2, instead |
|---|
| 197 | | of to this License. (If a newer version than version 2 of the ordinary GNU |
|---|
| 198 | | General Public License has appeared, then you can specify that version |
|---|
| 199 | | instead if you wish.) Do not make any other change in these notices. |
|---|
| 200 | | |
|---|
| 201 | | Once this change is made in a given copy, it is irreversible for that |
|---|
| 202 | | copy, so the ordinary GNU General Public License applies to all subsequent |
|---|
| 203 | | copies and derivative works made from that copy. |
|---|
| 204 | | |
|---|
| 205 | | This option is useful when you wish to copy part of the code of the |
|---|
| 206 | | Library into a program that is not a library. |
|---|
| 207 | | |
|---|
| 208 | | 4. You may copy and distribute the Library (or a portion or derivative of |
|---|
| 209 | | it, under Section 2) in object code or executable form under the terms of |
|---|
| 210 | | Sections 1 and 2 above provided that you accompany it with the complete |
|---|
| 211 | | corresponding machine-readable source code, which must be distributed |
|---|
| 212 | | under the terms of Sections 1 and 2 above on a medium customarily used for |
|---|
| 213 | | software interchange. |
|---|
| 214 | | |
|---|
| 215 | | If distribution of object code is made by offering access to copy from a |
|---|
| 216 | | designated place, then offering equivalent access to copy the source code |
|---|
| 217 | | from the same place satisfies the requirement to distribute the source |
|---|
| 218 | | code, even though third parties are not compelled to copy the source along |
|---|
| 219 | | with the object code. |
|---|
| 220 | | |
|---|
| 221 | | 5. A program that contains no derivative of any portion of the Library, |
|---|
| 222 | | but is designed to work with the Library by being compiled or linked with |
|---|
| 223 | | it, is called a "work that uses the Library". Such a work, in isolation, |
|---|
| 224 | | is not a derivative work of the Library, and therefore falls outside the |
|---|
| 225 | | scope of this License. |
|---|
| 226 | | |
|---|
| 227 | | However, linking a "work that uses the Library" with the Library creates |
|---|
| 228 | | an executable that is a derivative of the Library (because it contains |
|---|
| 229 | | portions of the Library), rather than a "work that uses the library". The |
|---|
| 230 | | executable is therefore covered by this License. Section 6 states terms |
|---|
| 231 | | for distribution of such executables. |
|---|
| 232 | | |
|---|
| 233 | | When a "work that uses the Library" uses material from a header file that |
|---|
| 234 | | is part of the Library, the object code for the work may be a derivative |
|---|
| 235 | | work of the Library even though the source code is not. Whether this is |
|---|
| 236 | | true is especially significant if the work can be linked without the |
|---|
| 237 | | Library, or if the work is itself a library. The threshold for this to be |
|---|
| 238 | | true is not precisely defined by law. |
|---|
| 239 | | |
|---|
| 240 | | If such an object file uses only numerical parameters, data structure |
|---|
| 241 | | layouts and accessors, and small macros and small inline functions (ten |
|---|
| 242 | | lines or less in length), then the use of the object file is unrestricted, |
|---|
| 243 | | regardless of whether it is legally a derivative work. (Executables |
|---|
| 244 | | containing this object code plus portions of the Library will still fall |
|---|
| 245 | | under Section 6.) |
|---|
| 246 | | |
|---|
| 247 | | Otherwise, if the work is a derivative of the Library, you may distribute |
|---|
| 248 | | the object code for the work under the terms of Section 6. Any executables |
|---|
| 249 | | containing that work also fall under Section 6, whether or not they are |
|---|
| 250 | | linked directly with the Library itself. |
|---|
| 251 | | |
|---|
| 252 | | 6. As an exception to the Sections above, you may also combine or link a |
|---|
| 253 | | "work that uses the Library" with the Library to produce a work containing |
|---|
| 254 | | portions of the Library, and distribute that work under terms of your |
|---|
| 255 | | choice, provided that the terms permit modification of the work for the |
|---|
| 256 | | customer's own use and reverse engineering for debugging such |
|---|
| 257 | | modifications. |
|---|
| 258 | | |
|---|
| 259 | | You must give prominent notice with each copy of the work that the Library |
|---|
| 260 | | is used in it and that the Library and its use are covered by this |
|---|
| 261 | | License. You must supply a copy of this License. If the work during |
|---|
| 262 | | execution displays copyright notices, you must include the copyright |
|---|
| 263 | | notice for the Library among them, as well as a reference directing the |
|---|
| 264 | | user to the copy of this License. Also, you must do one of these things: |
|---|
| 265 | | |
|---|
| 266 | | * a) Accompany the work with the complete corresponding |
|---|
| 267 | | machine-readable source code for the Library including whatever changes |
|---|
| 268 | | were used in the work (which must be distributed under Sections 1 and 2 |
|---|
| 269 | | above); and, if the work is an executable linked with the Library, with |
|---|
| 270 | | the complete machine-readable "work that uses the Library", as object code |
|---|
| 271 | | and/or source code, so that the user can modify the Library and then |
|---|
| 272 | | relink to produce a modified executable containing the modified Library. |
|---|
| 273 | | (It is understood that the user who changes the contents of definitions |
|---|
| 274 | | files in the Library will not necessarily be able to recompile the |
|---|
| 275 | | application to use the modified definitions.) |
|---|
| 276 | | * b) Use a suitable shared library mechanism for linking with the |
|---|
| 277 | | Library. A suitable mechanism is one that (1) uses at run time a copy of |
|---|
| 278 | | the library already present on the user's computer system, rather than |
|---|
| 279 | | copying library functions into the executable, and (2) will operate |
|---|
| 280 | | properly with a modified version of the library, if the user installs one, |
|---|
| 281 | | as long as the modified version is interface-compatible with the version |
|---|
| 282 | | that the work was made with. |
|---|
| 283 | | * c) Accompany the work with a written offer, valid for at least three |
|---|
| 284 | | years, to give the same user the materials specified in Subsection 6a, |
|---|
| 285 | | above, for a charge no more than the cost of performing this distribution. |
|---|
| 286 | | * d) If distribution of the work is made by offering access to copy |
|---|
| 287 | | from a designated place, offer equivalent access to copy the above |
|---|
| 288 | | specified materials from the same place. |
|---|
| 289 | | * e) Verify that the user has already received a copy of these materials |
|---|
| 290 | | or that you have already sent this user a copy. |
|---|
| 291 | | |
|---|
| 292 | | For an executable, the required form of the "work that uses the Library" |
|---|
| 293 | | must include any data and utility programs needed for reproducing the |
|---|
| 294 | | executable from it. However, as a special exception, the materials to be |
|---|
| 295 | | distributed need not include anything that is normally distributed (in |
|---|
| 296 | | either source or binary form) with the major components (compiler, kernel, |
|---|
| 297 | | and so on) of the operating system on which the executable runs, unless |
|---|
| 298 | | that component itself accompanies the executable. |
|---|
| 299 | | |
|---|
| 300 | | It may happen that this requirement contradicts the license restrictions |
|---|
| 301 | | of other proprietary libraries that do not normally accompany the |
|---|
| 302 | | operating system. Such a contradiction means you cannot use both them and |
|---|
| 303 | | the Library together in an executable that you distribute. |
|---|
| 304 | | |
|---|
| 305 | | 7. You may place library facilities that are a work based on the Library |
|---|
| 306 | | side-by-side in a single library together with other library facilities |
|---|
| 307 | | not covered by this License, and distribute such a combined library, |
|---|
| 308 | | provided that the separate distribution of the work based on the Library |
|---|
| 309 | | and of the other library facilities is otherwise permitted, and provided |
|---|
| 310 | | that you do these two things: |
|---|
| 311 | | |
|---|
| 312 | | * a) Accompany the combined library with a copy of the same work based |
|---|
| 313 | | on the Library, uncombined with any other library facilities. This must be |
|---|
| 314 | | distributed under the terms of the Sections above. |
|---|
| 315 | | * b) Give prominent notice with the combined library of the fact that part |
|---|
| 316 | | of it is a work based on the Library, and explaining where to find the |
|---|
| 317 | | accompanying uncombined form of the same work. |
|---|
| 318 | | |
|---|
| 319 | | 8. You may not copy, modify, sublicense, link with, or distribute the |
|---|
| 320 | | Library except as expressly provided under this License. Any attempt |
|---|
| 321 | | otherwise to copy, modify, sublicense, link with, or distribute the |
|---|
| 322 | | Library is void, and will automatically terminate your rights under this |
|---|
| 323 | | License. However, parties who have received copies, or rights, from you |
|---|
| 324 | | under this License will not have their licenses terminated so long as such |
|---|
| 325 | | parties remain in full compliance. |
|---|
| 326 | | |
|---|
| 327 | | 9. You are not required to accept this License, since you have not signed |
|---|
| 328 | | it. However, nothing else grants you permission to modify or distribute |
|---|
| 329 | | the Library or its derivative works. These actions are prohibited by law |
|---|
| 330 | | if you do not accept this License. Therefore, by modifying or distributing |
|---|
| 331 | | the Library (or any work based on the Library), you indicate your |
|---|
| 332 | | acceptance of this License to do so, and all its terms and conditions for |
|---|
| 333 | | copying, distributing or modifying the Library or works based on it. |
|---|
| 334 | | |
|---|
| 335 | | 10. Each time you redistribute the Library (or any work based on the |
|---|
| 336 | | Library), the recipient automatically receives a license from the original |
|---|
| 337 | | licensor to copy, distribute, link with or modify the Library subject to |
|---|
| 338 | | these terms and conditions. You may not impose any further restrictions on |
|---|
| 339 | | the recipients' exercise of the rights granted herein. You are not |
|---|
| 340 | | responsible for enforcing compliance by third parties with this License. |
|---|
| 341 | | |
|---|
| 342 | | 11. If, as a consequence of a court judgment or allegation of patent |
|---|
| 343 | | infringement or for any other reason (not limited to patent issues), |
|---|
| 344 | | conditions are imposed on you (whether by court order, agreement or |
|---|
| 345 | | otherwise) that contradict the conditions of this License, they do not |
|---|
| 346 | | excuse you from the conditions of this License. If you cannot distribute |
|---|
| 347 | | so as to satisfy simultaneously your obligations under this License and |
|---|
| 348 | | any other pertinent obligations, then as a consequence you may not |
|---|
| 349 | | distribute the Library at all. For example, if a patent license would not |
|---|
| 350 | | permit royalty-free redistribution of the Library by all those who receive |
|---|
| 351 | | copies directly or indirectly through you, then the only way you could |
|---|
| 352 | | satisfy both it and this License would be to refrain entirely from |
|---|
| 353 | | distribution of the Library. |
|---|
| 354 | | |
|---|
| 355 | | If any portion of this section is held invalid or unenforceable under any |
|---|
| 356 | | particular circumstance, the balance of the section is intended to apply, |
|---|
| | 281 | In addition, mere aggregation of another work not based on the Library |
|---|
| | 282 | with the Library (or with a work based on the Library) on a volume of |
|---|
| | 283 | a storage or distribution medium does not bring the other work under |
|---|
| | 284 | the scope of this License. |
|---|
| | 285 | |
|---|
| | 286 | 3. You may opt to apply the terms of the ordinary GNU General Public |
|---|
| | 287 | License instead of this License to a given copy of the Library. To do |
|---|
| | 288 | this, you must alter all the notices that refer to this License, so |
|---|
| | 289 | that they refer to the ordinary GNU General Public License, version 2, |
|---|
| | 290 | instead of to this License. (If a newer version than version 2 of the |
|---|
| | 291 | ordinary GNU General Public License has appeared, then you can specify |
|---|
| | 292 | that version instead if you wish.) Do not make any other change in |
|---|
| | 293 | these notices. |
|---|
| | 294 | |
|---|
| | 295 | Once this change is made in a given copy, it is irreversible for |
|---|
| | 296 | that copy, so the ordinary GNU General Public License applies to all |
|---|
| | 297 | subsequent copies and derivative works made from that copy. |
|---|
| | 298 | |
|---|
| | 299 | This option is useful when you wish to copy part of the code of |
|---|
| | 300 | the Library into a program that is not a library. |
|---|
| | 301 | |
|---|
| | 302 | 4. You may copy and distribute the Library (or a portion or |
|---|
| | 303 | derivative of it, under Section 2) in object code or executable form |
|---|
| | 304 | under the terms of Sections 1 and 2 above provided that you accompany |
|---|
| | 305 | it with the complete corresponding machine-readable source code, which |
|---|
| | 306 | must be distributed under the terms of Sections 1 and 2 above on a |
|---|
| | 307 | medium customarily used for software interchange. |
|---|
| | 308 | |
|---|
| | 309 | If distribution of object code is made by offering access to copy |
|---|
| | 310 | from a designated place, then offering equivalent access to copy the |
|---|
| | 311 | source code from the same place satisfies the requirement to |
|---|
| | 312 | distribute the source code, even though third parties are not |
|---|
| | 313 | compelled to copy the source along with the object code. |
|---|
| | 314 | |
|---|
| | 315 | 5. A program that contains no derivative of any portion of the |
|---|
| | 316 | Library, but is designed to work with the Library by being compiled or |
|---|
| | 317 | linked with it, is called a "work that uses the Library". Such a |
|---|
| | 318 | work, in isolation, is not a derivative work of the Library, and |
|---|
| | 319 | therefore falls outside the scope of this License. |
|---|
| | 320 | |
|---|
| | 321 | However, linking a "work that uses the Library" with the Library |
|---|
| | 322 | creates an executable that is a derivative of the Library (because it |
|---|
| | 323 | contains portions of the Library), rather than a "work that uses the |
|---|
| | 324 | library". The executable is therefore covered by this License. |
|---|
| | 325 | Section 6 states terms for distribution of such executables. |
|---|
| | 326 | |
|---|
| | 327 | When a "work that uses the Library" uses material from a header file |
|---|
| | 328 | that is part of the Library, the object code for the work may be a |
|---|
| | 329 | derivative work of the Library even though the source code is not. |
|---|
| | 330 | Whether this is true is especially significant if the work can be |
|---|
| | 331 | linked without the Library, or if the work is itself a library. The |
|---|
| | 332 | threshold for this to be true is not precisely defined by law. |
|---|
| | 333 | |
|---|
| | 334 | If such an object file uses only numerical parameters, data |
|---|
| | 335 | structure layouts and accessors, and small macros and small inline |
|---|
| | 336 | functions (ten lines or less in length), then the use of the object |
|---|
| | 337 | file is unrestricted, regardless of whether it is legally a derivative |
|---|
| | 338 | work. (Executables containing this object code plus portions of the |
|---|
| | 339 | Library will still fall under Section 6.) |
|---|
| | 340 | |
|---|
| | 341 | Otherwise, if the work is a derivative of the Library, you may |
|---|
| | 342 | distribute the object code for the work under the terms of Section 6. |
|---|
| | 343 | Any executables containing that work also fall under Section 6, |
|---|
| | 344 | whether or not they are linked directly with the Library itself. |
|---|
| | 345 | |
|---|
| | 346 | 6. As an exception to the Sections above, you may also combine or |
|---|
| | 347 | link a "work that uses the Library" with the Library to produce a |
|---|
| | 348 | work containing portions of the Library, and distribute that work |
|---|
| | 349 | under terms of your choice, provided that the terms permit |
|---|
| | 350 | modification of the work for the customer's own use and reverse |
|---|
| | 351 | engineering for debugging such modifications. |
|---|
| | 352 | |
|---|
| | 353 | You must give prominent notice with each copy of the work that the |
|---|
| | 354 | Library is used in it and that the Library and its use are covered by |
|---|
| | 355 | this License. You must supply a copy of this License. If the work |
|---|
| | 356 | during execution displays copyright notices, you must include the |
|---|
| | 357 | copyright notice for the Library among them, as well as a reference |
|---|
| | 358 | directing the user to the copy of this License. Also, you must do one |
|---|
| | 359 | of these things: |
|---|
| | 360 | |
|---|
| | 361 | a) Accompany the work with the complete corresponding |
|---|
| | 362 | machine-readable source code for the Library including whatever |
|---|
| | 363 | changes were used in the work (which must be distributed under |
|---|
| | 364 | Sections 1 and 2 above); and, if the work is an executable linked |
|---|
| | 365 | with the Library, with the complete machine-readable "work that |
|---|
| | 366 | uses the Library", as object code and/or source code, so that the |
|---|
| | 367 | user can modify the Library and then relink to produce a modified |
|---|
| | 368 | executable containing the modified Library. (It is understood |
|---|
| | 369 | that the user who changes the contents of definitions files in the |
|---|
| | 370 | Library will not necessarily be able to recompile the application |
|---|
| | 371 | to use the modified definitions.) |
|---|
| | 372 | |
|---|
| | 373 | b) Use a suitable shared library mechanism for linking with the |
|---|
| | 374 | Library. A suitable mechanism is one that (1) uses at run time a |
|---|
| | 375 | copy of the library already present on the user's computer system, |
|---|
| | 376 | rather than copying library functions into the executable, and (2) |
|---|
| | 377 | will operate properly with a modified version of the library, if |
|---|
| | 378 | the user installs one, as long as the modified version is |
|---|
| | 379 | interface-compatible with the version that the work was made with. |
|---|
| | 380 | |
|---|
| | 381 | c) Accompany the work with a written offer, valid for at |
|---|
| | 382 | least three years, to give the same user the materials |
|---|
| | 383 | specified in Subsection 6a, above, for a charge no more |
|---|
| | 384 | than the cost of performing this distribution. |
|---|
| | 385 | |
|---|
| | 386 | d) If distribution of the work is made by offering access to copy |
|---|
| | 387 | from a designated place, offer equivalent access to copy the above |
|---|
| | 388 | specified materials from the same place. |
|---|
| | 389 | |
|---|
| | 390 | e) Verify that the user has already received a copy of these |
|---|
| | 391 | materials or that you have already sent this user a copy. |
|---|
| | 392 | |
|---|
| | 393 | For an executable, the required form of the "work that uses the |
|---|
| | 394 | Library" must include any data and utility programs needed for |
|---|
| | 395 | reproducing the executable from it. However, as a special exception, |
|---|
| | 396 | the materials to be distributed need not include anything that is |
|---|
| | 397 | normally distributed (in either source or binary form) with the major |
|---|
| | 398 | components (compiler, kernel, and so on) of the operating system on |
|---|
| | 399 | which the executable runs, unless that component itself accompanies |
|---|
| | 400 | the executable. |
|---|
| | 401 | |
|---|
| | 402 | It may happen that this requirement contradicts the license |
|---|
| | 403 | restrictions of other proprietary libraries that do not normally |
|---|
| | 404 | accompany the operating system. Such a contradiction means you cannot |
|---|
| | 405 | use both them and the Library together in an executable that you |
|---|
| | 406 | distribute. |
|---|
| | 407 | |
|---|
| | 408 | 7. You may place library facilities that are a work based on the |
|---|
| | 409 | Library side-by-side in a single library together with other library |
|---|
| | 410 | facilities not covered by this License, and distribute such a combined |
|---|
| | 411 | library, provided that the separate distribution of the work based on |
|---|
| | 412 | the Library and of the other library facilities is otherwise |
|---|
| | 413 | permitted, and provided that you do these two things: |
|---|
| | 414 | |
|---|
| | 415 | a) Accompany the combined library with a copy of the same work |
|---|
| | 416 | based on the Library, uncombined with any other library |
|---|
| | 417 | facilities. This must be distributed under the terms of the |
|---|
| | 418 | Sections above. |
|---|
| | 419 | |
|---|
| | 420 | b) Give prominent notice with the combined library of the fact |
|---|
| | 421 | that part of it is a work based on the Library, and explaining |
|---|
| | 422 | where to find the accompanying uncombined form of the same work. |
|---|
| | 423 | |
|---|
| | 424 | 8. You may not copy, modify, sublicense, link with, or distribute |
|---|
| | 425 | the Library except as expressly provided under this License. Any |
|---|
| | 426 | attempt otherwise to copy, modify, sublicense, link with, or |
|---|
| | 427 | distribute the Library is void, and will automatically terminate your |
|---|
| | 428 | rights under this License. However, parties who have received copies, |
|---|
| | 429 | or rights, from you under this License will not have their licenses |
|---|
| | 430 | terminated so long as such parties remain in full compliance. |
|---|
| | 431 | |
|---|
| | 432 | 9. You are not required to accept this License, since you have not |
|---|
| | 433 | signed it. However, nothing else grants you permission to modify or |
|---|
| | 434 | distribute the Library or its derivative works. These actions are |
|---|
| | 435 | prohibited by law if you do not accept this License. Therefore, by |
|---|
| | 436 | modifying or distributing the Library (or any work based on the |
|---|
| | 437 | Library), you indicate your acceptance of this License to do so, and |
|---|
| | 438 | all its terms and conditions for copying, distributing or modifying |
|---|
| | 439 | the Library or works based on it. |
|---|
| | 440 | |
|---|
| | 441 | 10. Each time you redistribute the Library (or any work based on the |
|---|
| | 442 | Library), the recipient automatically receives a license from the |
|---|
| | 443 | original licensor to copy, distribute, link with or modify the Library |
|---|
| | 444 | subject to these terms and conditions. You may not impose any further |
|---|
| | 445 | restrictions on the recipients' exercise of the rights granted herein. |
|---|
| | 446 | You are not responsible for enforcing compliance by third parties with |
|---|
| | 447 | this License. |
|---|
| | 448 | |
|---|
| | 449 | 11. If, as a consequence of a court judgment or allegation of patent |
|---|
| | 450 | infringement or for any other reason (not limited to patent issues), |
|---|
| | 451 | conditions are imposed on you (whether by court order, agreement or |
|---|
| | 452 | otherwise) that contradict the conditions of this License, they do not |
|---|
| | 453 | excuse you from the conditions of this License. If you cannot |
|---|
| | 454 | distribute so as to satisfy simultaneously your obligations under this |
|---|
| | 455 | License and any other pertinent obligations, then as a consequence you |
|---|
| | 456 | may not distribute the Library at all. For example, if a patent |
|---|
| | 457 | license would not permit royalty-free redistribution of the Library by |
|---|
| | 458 | all those who receive copies directly or indirectly through you, then |
|---|
| | 459 | the only way you could satisfy both it and this License would be to |
|---|
| | 460 | refrain entirely from distribution of the Library. |
|---|
| | 461 | |
|---|
| | 462 | If any portion of this section is held invalid or unenforceable under any |
|---|
| | 463 | particular circumstance, the balance of the section is intended to apply, |
|---|
| 380 | | 13. The Free Software Foundation may publish revised and/or new versions |
|---|
| 381 | | of the Lesser General Public License from time to time. Such new versions |
|---|
| 382 | | will be similar in spirit to the present version, but may differ in detail |
|---|
| 383 | | to address new problems or concerns. |
|---|
| 384 | | |
|---|
| 385 | | Each version is given a distinguishing version number. If the Library |
|---|
| 386 | | specifies a version number of this License which applies to it and "any |
|---|
| 387 | | later version", you have the option of following the terms and conditions |
|---|
| 388 | | either of that version or of any later version published by the Free |
|---|
| 389 | | Software Foundation. If the Library does not specify a license version |
|---|
| 390 | | number, you may choose any version ever published by the Free Software |
|---|
| 391 | | Foundation. |
|---|
| 392 | | |
|---|
| 393 | | 14. If you wish to incorporate parts of the Library into other free |
|---|
| 394 | | programs whose distribution conditions are incompatible with these, write |
|---|
| 395 | | to the author to ask for permission. For software which is copyrighted by |
|---|
| 396 | | the Free Software Foundation, write to the Free Software Foundation; we |
|---|
| 397 | | sometimes make exceptions for this. Our decision will be guided by the two |
|---|
| 398 | | goals of preserving the free status of all derivatives of our free |
|---|
| 399 | | software and of promoting the sharing and reuse of software generally. |

| 401 | | NO WARRANTY |
|---|
| 402 | | |
|---|
| 403 | | 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY |
|---|
| 404 | | FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN |

| 405 | | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES |
|---|
| 406 | | PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED |

| 407 | | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF |
|---|
| 408 | | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS |
|---|
| 409 | | TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE |
|---|
| 410 | | LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, |
|---|
| 411 | | REPAIR OR CORRECTION. |
|---|
| 412 | | |
|---|
| 413 | | 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING |
|---|
| 414 | | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR |
|---|
| 415 | | REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, |
|---|
| 416 | | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES |
|---|
| 417 | | ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT |
|---|

|---|
| 419 | | SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE |

| | 535 | How to Apply These Terms to Your New Libraries |
|---|
| | 536 | |
|---|
| | 537 | If you develop a new library, and you want it to be of the greatest |
|---|
| | 538 | possible use to the public, we recommend making it free software that |
|---|
| | 539 | everyone can redistribute and change. You can do so by permitting |
|---|
| | 540 | redistribution under these terms (or, alternatively, under the terms of the |
|---|
| | 541 | |
|---|
