hudakz | 1:4f5c042a2d34 | 12 | |
hudakz | 1:4f5c042a2d34 | 13 | Preamble |
hudakz | 1:4f5c042a2d34 | 14 | |
hudakz | 1:4f5c042a2d34 | 15 | The licenses for most software are designed to take away your |
hudakz | 1:4f5c042a2d34 | 16 | freedom to share and change it. By contrast, the GNU General Public |
hudakz | 1:4f5c042a2d34 | 17 | Licenses are intended to guarantee your freedom to share and change |
hudakz | 1:4f5c042a2d34 | 18 | free software--to make sure the software is free for all its users. |
hudakz | 1:4f5c042a2d34 | 19 | |
hudakz | 1:4f5c042a2d34 | 20 | This license, the Lesser General Public License, applies to some |
hudakz | 1:4f5c042a2d34 | 21 | specially designated software packages--typically libraries--of the |
hudakz | 1:4f5c042a2d34 | 22 | Free Software Foundation and other authors who decide to use it. You |
hudakz | 1:4f5c042a2d34 | 23 | can use it too, but we suggest you first think carefully about whether |
hudakz | 1:4f5c042a2d34 | 24 | this license or the ordinary General Public License is the better |
hudakz | 1:4f5c042a2d34 | 25 | strategy to use in any particular case, based on the explanations below. |
hudakz | 1:4f5c042a2d34 | 26 | |
hudakz | 1:4f5c042a2d34 | 27 | When we speak of free software, we are referring to freedom of use, |
hudakz | 1:4f5c042a2d34 | 28 | not price. Our General Public Licenses are designed to make sure that |
hudakz | 1:4f5c042a2d34 | 29 | you have the freedom to distribute copies of free software (and charge |
hudakz | 1:4f5c042a2d34 | 30 | for this service if you wish); that you receive source code or can get |
hudakz | 1:4f5c042a2d34 | 31 | it if you want it; that you can change the software and use pieces of |
hudakz | 1:4f5c042a2d34 | 32 | it in new free programs; and that you are informed that you can do |
hudakz | 1:4f5c042a2d34 | 33 | these things. |
hudakz | 1:4f5c042a2d34 | 34 | |
hudakz | 1:4f5c042a2d34 | 35 | To protect your rights, we need to make restrictions that forbid |
hudakz | 1:4f5c042a2d34 | 36 | distributors to deny you these rights or to ask you to surrender these |
hudakz | 1:4f5c042a2d34 | 37 | rights. These restrictions translate to certain responsibilities for |
hudakz | 1:4f5c042a2d34 | 38 | you if you distribute copies of the library or if you modify it. |
hudakz | 1:4f5c042a2d34 | 39 | |
hudakz | 1:4f5c042a2d34 | 40 | For example, if you distribute copies of the library, whether gratis |
hudakz | 1:4f5c042a2d34 | 41 | or for a fee, you must give the recipients all the rights that we gave |
hudakz | 1:4f5c042a2d34 | 42 | you. You must make sure that they, too, receive or can get the source |
hudakz | 1:4f5c042a2d34 | 43 | code. If you link other code with the library, you must provide |
hudakz | 1:4f5c042a2d34 | 44 | complete object files to the recipients, so that they can relink them |
hudakz | 1:4f5c042a2d34 | 45 | with the library after making changes to the library and recompiling |
hudakz | 1:4f5c042a2d34 | 46 | it. And you must show them these terms so they know their rights. |
hudakz | 1:4f5c042a2d34 | 47 | |
hudakz | 1:4f5c042a2d34 | 48 | We protect your rights with a two-step method: (1) we copyright the |
hudakz | 1:4f5c042a2d34 | 49 | library, and (2) we offer you this license, which gives you legal |
hudakz | 1:4f5c042a2d34 | 50 | permission to copy, distribute and/or modify the library. |
hudakz | 1:4f5c042a2d34 | 51 | |
hudakz | 1:4f5c042a2d34 | 52 | To protect each distributor, we want to make it very clear that |
hudakz | 1:4f5c042a2d34 | 53 | there is no warranty for the free library. Also, if the library is |
hudakz | 1:4f5c042a2d34 | 54 | modified by someone else and passed on, the recipients should know |
hudakz | 1:4f5c042a2d34 | 55 | that what they have is not the original version, so that the original |
hudakz | 1:4f5c042a2d34 | 56 | author's reputation will not be affected by problems that might be |
hudakz | 1:4f5c042a2d34 | 57 | introduced by others. |
hudakz | 1:4f5c042a2d34 | 58 | |
hudakz | 1:4f5c042a2d34 | 59 | Finally, software patents pose a constant threat to the existence of |
hudakz | 1:4f5c042a2d34 | 60 | any free program. We wish to make sure that a company cannot |
hudakz | 1:4f5c042a2d34 | 61 | effectively restrict the users of a free program by obtaining a |
hudakz | 1:4f5c042a2d34 | 62 | restrictive license from a patent holder. Therefore, we insist that |
hudakz | 1:4f5c042a2d34 | 63 | any patent license obtained for a version of the library must be |
hudakz | 1:4f5c042a2d34 | 64 | consistent with the full freedom of use specified in this license. |
hudakz | 1:4f5c042a2d34 | 65 | |
hudakz | 1:4f5c042a2d34 | 66 | Most GNU software, including some libraries, is covered by the |
hudakz | 1:4f5c042a2d34 | 67 | ordinary GNU General Public License. This license, the GNU Lesser |
hudakz | 1:4f5c042a2d34 | 68 | General Public License, applies to certain designated libraries, and |
hudakz | 1:4f5c042a2d34 | 69 | is quite different from the ordinary General Public License. We use |
hudakz | 1:4f5c042a2d34 | 70 | this license for certain libraries in order to permit linking those |
hudakz | 1:4f5c042a2d34 | 71 | libraries into non-free programs. |
hudakz | 1:4f5c042a2d34 | 72 | |
hudakz | 1:4f5c042a2d34 | 73 | When a program is linked with a library, whether statically or using |
hudakz | 1:4f5c042a2d34 | 74 | a shared library, the combination of the two is legally speaking a |
hudakz | 1:4f5c042a2d34 | 75 | combined work, a derivative of the original library. The ordinary |
hudakz | 1:4f5c042a2d34 | 76 | General Public License therefore permits such linking only if the |
hudakz | 1:4f5c042a2d34 | 77 | entire combination fits its criteria of freedom. The Lesser General |
hudakz | 1:4f5c042a2d34 | 78 | Public License permits more lax criteria for linking other code with |
hudakz | 1:4f5c042a2d34 | 79 | the library. |
hudakz | 1:4f5c042a2d34 | 80 | |
hudakz | 1:4f5c042a2d34 | 81 | We call this license the "Lesser" General Public License because it |
hudakz | 1:4f5c042a2d34 | 82 | does Less to protect the user's freedom than the ordinary General |
hudakz | 1:4f5c042a2d34 | 83 | Public License. It also provides other free software developers Less |
hudakz | 1:4f5c042a2d34 | 84 | of an advantage over competing non-free programs. These disadvantages |
hudakz | 1:4f5c042a2d34 | 85 | are the reason we use the ordinary General Public License for many |
hudakz | 1:4f5c042a2d34 | 86 | libraries. However, the Lesser license provides advantages in certain |
hudakz | 1:4f5c042a2d34 | 87 | special circumstances. |
hudakz | 1:4f5c042a2d34 | 88 | |
hudakz | 1:4f5c042a2d34 | 89 | For example, on rare occasions, there may be a special need to |
hudakz | 1:4f5c042a2d34 | 90 | encourage the widest possible use of a certain library, so that it becomes |
hudakz | 1:4f5c042a2d34 | 91 | a de-facto standard. To achieve this, non-free programs must be |
hudakz | 1:4f5c042a2d34 | 92 | allowed to use the library. A more frequent case is that a free |
hudakz | 1:4f5c042a2d34 | 93 | library does the same job as widely used non-free libraries. In this |
hudakz | 1:4f5c042a2d34 | 94 | case, there is little to gain by limiting the free library to free |
hudakz | 1:4f5c042a2d34 | 95 | software only, so we use the Lesser General Public License. |
hudakz | 1:4f5c042a2d34 | 96 | |
hudakz | 1:4f5c042a2d34 | 97 | In other cases, permission to use a particular library in non-free |
hudakz | 1:4f5c042a2d34 | 98 | programs enables a greater number of people to use a large body of |
hudakz | 1:4f5c042a2d34 | 99 | free software. For example, permission to use the GNU C Library in |
hudakz | 1:4f5c042a2d34 | 100 | non-free programs enables many more people to use the whole GNU |
hudakz | 1:4f5c042a2d34 | 101 | operating system, as well as its variant, the GNU/Linux operating |
hudakz | 1:4f5c042a2d34 | 102 | system. |
hudakz | 1:4f5c042a2d34 | 103 | |
hudakz | 1:4f5c042a2d34 | 104 | Although the Lesser General Public License is Less protective of the |
hudakz | 1:4f5c042a2d34 | 105 | users' freedom, it does ensure that the user of a program that is |
hudakz | 1:4f5c042a2d34 | 106 | linked with the Library has the freedom and the wherewithal to run |
hudakz | 1:4f5c042a2d34 | 107 | that program using a modified version of the Library. |
hudakz | 1:4f5c042a2d34 | 108 | |
hudakz | 1:4f5c042a2d34 | 109 | The precise terms and conditions for copying, distribution and |
hudakz | 1:4f5c042a2d34 | 110 | modification follow. Pay close attention to the difference between a |
hudakz | 1:4f5c042a2d34 | 111 | "work based on the library" and a "work that uses the library". The |
hudakz | 1:4f5c042a2d34 | 112 | former contains code derived from the library, whereas the latter must |
hudakz | 1:4f5c042a2d34 | 113 | be combined with the library in order to run. |
hudakz | 1:4f5c042a2d34 | 114 | |
hudakz | 1:4f5c042a2d34 | 115 | GNU LESSER GENERAL PUBLIC LICENSE |
hudakz | 1:4f5c042a2d34 | 116 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
hudakz | 1:4f5c042a2d34 | 117 | |
hudakz | 1:4f5c042a2d34 | 118 | 0. This License Agreement applies to any software library or other |
hudakz | 1:4f5c042a2d34 | 119 | program which contains a notice placed by the copyright holder or |
hudakz | 1:4f5c042a2d34 | 120 | other authorized party saying it may be distributed under the terms of |
hudakz | 1:4f5c042a2d34 | 121 | this Lesser General Public License (also called "this License"). |
hudakz | 1:4f5c042a2d34 | 122 | Each licensee is addressed as "you". |
hudakz | 1:4f5c042a2d34 | 123 | |
hudakz | 1:4f5c042a2d34 | 124 | A "library" means a collection of software functions and/or data |
hudakz | 1:4f5c042a2d34 | 125 | prepared so as to be conveniently linked with application programs |
hudakz | 1:4f5c042a2d34 | 126 | (which use some of those functions and data) to form executables. |
hudakz | 1:4f5c042a2d34 | 127 | |
hudakz | 1:4f5c042a2d34 | 128 | The "Library", below, refers to any such software library or work |
hudakz | 1:4f5c042a2d34 | 129 | which has been distributed under these terms. A "work based on the |
hudakz | 1:4f5c042a2d34 | 130 | Library" means either the Library or any derivative work under |
hudakz | 1:4f5c042a2d34 | 131 | copyright law: that is to say, a work containing the Library or a |
hudakz | 1:4f5c042a2d34 | 132 | portion of it, either verbatim or with modifications and/or translated |
hudakz | 1:4f5c042a2d34 | 133 | straightforwardly into another language. (Hereinafter, translation is |
hudakz | 1:4f5c042a2d34 | 134 | included without limitation in the term "modification".) |
hudakz | 1:4f5c042a2d34 | 135 | |
hudakz | 1:4f5c042a2d34 | 136 | "Source code" for a work means the preferred form of the work for |
hudakz | 1:4f5c042a2d34 | 137 | making modifications to it. For a library, complete source code means |
hudakz | 1:4f5c042a2d34 | 138 | all the source code for all modules it contains, plus any associated |
hudakz | 1:4f5c042a2d34 | 139 | interface definition files, plus the scripts used to control compilation |
hudakz | 1:4f5c042a2d34 | 140 | and installation of the library. |
hudakz | 1:4f5c042a2d34 | 141 | |
hudakz | 1:4f5c042a2d34 | 142 | Activities other than copying, distribution and modification are not |
hudakz | 1:4f5c042a2d34 | 143 | covered by this License; they are outside its scope. The act of |
hudakz | 1:4f5c042a2d34 | 144 | running a program using the Library is not restricted, and output from |
hudakz | 1:4f5c042a2d34 | 145 | such a program is covered only if its contents constitute a work based |
hudakz | 1:4f5c042a2d34 | 146 | on the Library (independent of the use of the Library in a tool for |
hudakz | 1:4f5c042a2d34 | 147 | writing it). Whether that is true depends on what the Library does |
hudakz | 1:4f5c042a2d34 | 148 | and what the program that uses the Library does. |
hudakz | 1:4f5c042a2d34 | 149 | |
hudakz | 1:4f5c042a2d34 | 150 | 1. You may copy and distribute verbatim copies of the Library's |
hudakz | 1:4f5c042a2d34 | 151 | complete source code as you receive it, in any medium, provided that |
hudakz | 1:4f5c042a2d34 | 152 | you conspicuously and appropriately publish on each copy an |
hudakz | 1:4f5c042a2d34 | 153 | appropriate copyright notice and disclaimer of warranty; keep intact |
hudakz | 1:4f5c042a2d34 | 154 | all the notices that refer to this License and to the absence of any |
hudakz | 1:4f5c042a2d34 | 155 | warranty; and distribute a copy of this License along with the |
hudakz | 1:4f5c042a2d34 | 156 | Library. |
hudakz | 1:4f5c042a2d34 | 157 | |
hudakz | 1:4f5c042a2d34 | 158 | You may charge a fee for the physical act of transferring a copy, |
hudakz | 1:4f5c042a2d34 | 159 | and you may at your option offer warranty protection in exchange for a |
hudakz | 1:4f5c042a2d34 | 160 | fee. |
hudakz | 1:4f5c042a2d34 | 161 | |
hudakz | 1:4f5c042a2d34 | 162 | 2. You may modify your copy or copies of the Library or any portion |
hudakz | 1:4f5c042a2d34 | 163 | of it, thus forming a work based on the Library, and copy and |
hudakz | 1:4f5c042a2d34 | 164 | distribute such modifications or work under the terms of Section 1 |
hudakz | 1:4f5c042a2d34 | 165 | above, provided that you also meet all of these conditions: |
hudakz | 1:4f5c042a2d34 | 166 | |
hudakz | 1:4f5c042a2d34 | 167 | a) The modified work must itself be a software library. |
hudakz | 1:4f5c042a2d34 | 168 | |
hudakz | 1:4f5c042a2d34 | 169 | b) You must cause the files modified to carry prominent notices |
hudakz | 1:4f5c042a2d34 | 170 | stating that you changed the files and the date of any change. |
hudakz | 1:4f5c042a2d34 | 171 | |
hudakz | 1:4f5c042a2d34 | 172 | c) You must cause the whole of the work to be licensed at no |
hudakz | 1:4f5c042a2d34 | 173 | charge to all third parties under the terms of this License. |
hudakz | 1:4f5c042a2d34 | 174 | |
hudakz | 1:4f5c042a2d34 | 175 | d) If a facility in the modified Library refers to a function or a |
hudakz | 1:4f5c042a2d34 | 176 | table of data to be supplied by an application program that uses |
hudakz | 1:4f5c042a2d34 | 177 | the facility, other than as an argument passed when the facility |
hudakz | 1:4f5c042a2d34 | 178 | is invoked, then you must make a good faith effort to ensure that, |
hudakz | 1:4f5c042a2d34 | 179 | in the event an application does not supply such function or |
hudakz | 1:4f5c042a2d34 | 180 | table, the facility still operates, and performs whatever part of |
hudakz | 1:4f5c042a2d34 | 181 | its purpose remains meaningful. |
hudakz | 1:4f5c042a2d34 | 182 | |
hudakz | 1:4f5c042a2d34 | 183 | (For example, a function in a library to compute square roots has |
hudakz | 1:4f5c042a2d34 | 184 | a purpose that is entirely well-defined independent of the |
hudakz | 1:4f5c042a2d34 | 185 | application. Therefore, Subsection 2d requires that any |
hudakz | 1:4f5c042a2d34 | 186 | application-supplied function or table used by this function must |
hudakz | 1:4f5c042a2d34 | 187 | be optional: if the application does not supply it, the square |
hudakz | 1:4f5c042a2d34 | 188 | root function must still compute square roots.) |
hudakz | 1:4f5c042a2d34 | 189 | |
hudakz | 1:4f5c042a2d34 | 190 | These requirements apply to the modified work as a whole. If |
hudakz | 1:4f5c042a2d34 | 191 | identifiable sections of that work are not derived from the Library, |
hudakz | 1:4f5c042a2d34 | 192 | and can be reasonably considered independent and separate works in |
hudakz | 1:4f5c042a2d34 | 193 | themselves, then this License, and its terms, do not apply to those |
hudakz | 1:4f5c042a2d34 | 194 | sections when you distribute them as separate works. But when you |
hudakz | 1:4f5c042a2d34 | 195 | distribute the same sections as part of a whole which is a work based |
hudakz | 1:4f5c042a2d34 | 196 | on the Library, the distribution of the whole must be on the terms of |
hudakz | 1:4f5c042a2d34 | 197 | this License, whose permissions for other licensees extend to the |
hudakz | 1:4f5c042a2d34 | 198 | entire whole, and thus to each and every part regardless of who wrote |
hudakz | 1:4f5c042a2d34 | 199 | it. |
hudakz | 1:4f5c042a2d34 | 200 | |
hudakz | 1:4f5c042a2d34 | 201 | Thus, it is not the intent of this section to claim rights or contest |
hudakz | 1:4f5c042a2d34 | 202 | your rights to work written entirely by you; rather, the intent is to |
hudakz | 1:4f5c042a2d34 | 203 | exercise the right to control the distribution of derivative or |
hudakz | 1:4f5c042a2d34 | 204 | collective works based on the Library. |
hudakz | 1:4f5c042a2d34 | 205 | |
hudakz | 1:4f5c042a2d34 | 206 | In addition, mere aggregation of another work not based on the Library |
hudakz | 1:4f5c042a2d34 | 207 | with the Library (or with a work based on the Library) on a volume of |
hudakz | 1:4f5c042a2d34 | 208 | a storage or distribution medium does not bring the other work under |
hudakz | 1:4f5c042a2d34 | 209 | the scope of this License. |
hudakz | 1:4f5c042a2d34 | 210 | |
hudakz | 1:4f5c042a2d34 | 211 | 3. You may opt to apply the terms of the ordinary GNU General Public |
hudakz | 1:4f5c042a2d34 | 212 | License instead of this License to a given copy of the Library. To do |
hudakz | 1:4f5c042a2d34 | 213 | this, you must alter all the notices that refer to this License, so |
hudakz | 1:4f5c042a2d34 | 214 | that they refer to the ordinary GNU General Public License, version 2, |
hudakz | 1:4f5c042a2d34 | 215 | instead of to this License. (If a newer version than version 2 of the |
hudakz | 1:4f5c042a2d34 | 216 | ordinary GNU General Public License has appeared, then you can specify |
hudakz | 1:4f5c042a2d34 | 217 | that version instead if you wish.) Do not make any other change in |
hudakz | 1:4f5c042a2d34 | 218 | these notices. |
hudakz | 1:4f5c042a2d34 | 219 | |
hudakz | 1:4f5c042a2d34 | 220 | Once this change is made in a given copy, it is irreversible for |
hudakz | 1:4f5c042a2d34 | 221 | that copy, so the ordinary GNU General Public License applies to all |
hudakz | 1:4f5c042a2d34 | 222 | subsequent copies and derivative works made from that copy. |
hudakz | 1:4f5c042a2d34 | 223 | |
hudakz | 1:4f5c042a2d34 | 224 | This option is useful when you wish to copy part of the code of |
hudakz | 1:4f5c042a2d34 | 225 | the Library into a program that is not a library. |
hudakz | 1:4f5c042a2d34 | 226 | |
hudakz | 1:4f5c042a2d34 | 227 | 4. You may copy and distribute the Library (or a portion or |
hudakz | 1:4f5c042a2d34 | 228 | derivative of it, under Section 2) in object code or executable form |
hudakz | 1:4f5c042a2d34 | 229 | under the terms of Sections 1 and 2 above provided that you accompany |
hudakz | 1:4f5c042a2d34 | 230 | it with the complete corresponding machine-readable source code, which |
hudakz | 1:4f5c042a2d34 | 231 | must be distributed under the terms of Sections 1 and 2 above on a |
hudakz | 1:4f5c042a2d34 | 232 | medium customarily used for software interchange. |
hudakz | 1:4f5c042a2d34 | 233 | |
hudakz | 1:4f5c042a2d34 | 234 | If distribution of object code is made by offering access to copy |
hudakz | 1:4f5c042a2d34 | 235 | from a designated place, then offering equivalent access to copy the |
hudakz | 1:4f5c042a2d34 | 236 | source code from the same place satisfies the requirement to |
hudakz | 1:4f5c042a2d34 | 237 | distribute the source code, even though third parties are not |
hudakz | 1:4f5c042a2d34 | 238 | compelled to copy the source along with the object code. |
hudakz | 1:4f5c042a2d34 | 239 | |
hudakz | 1:4f5c042a2d34 | 240 | 5. A program that contains no derivative of any portion of the |
hudakz | 1:4f5c042a2d34 | 241 | Library, but is designed to work with the Library by being compiled or |
hudakz | 1:4f5c042a2d34 | 242 | linked with it, is called a "work that uses the Library". Such a |
hudakz | 1:4f5c042a2d34 | 243 | work, in isolation, is not a derivative work of the Library, and |
hudakz | 1:4f5c042a2d34 | 244 | therefore falls outside the scope of this License. |
hudakz | 1:4f5c042a2d34 | 245 | |
hudakz | 1:4f5c042a2d34 | 246 | However, linking a "work that uses the Library" with the Library |
hudakz | 1:4f5c042a2d34 | 247 | creates an executable that is a derivative of the Library (because it |
hudakz | 1:4f5c042a2d34 | 248 | contains portions of the Library), rather than a "work that uses the |
hudakz | 1:4f5c042a2d34 | 249 | library". The executable is therefore covered by this License. |
hudakz | 1:4f5c042a2d34 | 250 | Section 6 states terms for distribution of such executables. |
hudakz | 1:4f5c042a2d34 | 251 | |
hudakz | 1:4f5c042a2d34 | 252 | When a "work that uses the Library" uses material from a header file |
hudakz | 1:4f5c042a2d34 | 253 | that is part of the Library, the object code for the work may be a |
hudakz | 1:4f5c042a2d34 | 254 | derivative work of the Library even though the source code is not. |
hudakz | 1:4f5c042a2d34 | 255 | Whether this is true is especially significant if the work can be |
hudakz | 1:4f5c042a2d34 | 256 | linked without the Library, or if the work is itself a library. The |
hudakz | 1:4f5c042a2d34 | 257 | threshold for this to be true is not precisely defined by law. |
hudakz | 1:4f5c042a2d34 | 258 | |
hudakz | 1:4f5c042a2d34 | 259 | If such an object file uses only numerical parameters, data |
hudakz | 1:4f5c042a2d34 | 260 | structure layouts and accessors, and small macros and small inline |
hudakz | 1:4f5c042a2d34 | 261 | functions (ten lines or less in length), then the use of the object |
hudakz | 1:4f5c042a2d34 | 262 | file is unrestricted, regardless of whether it is legally a derivative |
hudakz | 1:4f5c042a2d34 | 263 | work. (Executables containing this object code plus portions of the |
hudakz | 1:4f5c042a2d34 | 264 | Library will still fall under Section 6.) |
hudakz | 1:4f5c042a2d34 | 265 | |
hudakz | 1:4f5c042a2d34 | 266 | Otherwise, if the work is a derivative of the Library, you may |
hudakz | 1:4f5c042a2d34 | 267 | distribute the object code for the work under the terms of Section 6. |
hudakz | 1:4f5c042a2d34 | 268 | Any executables containing that work also fall under Section 6, |
hudakz | 1:4f5c042a2d34 | 269 | whether or not they are linked directly with the Library itself. |
hudakz | 1:4f5c042a2d34 | 270 | |
hudakz | 1:4f5c042a2d34 | 271 | 6. As an exception to the Sections above, you may also combine or |
hudakz | 1:4f5c042a2d34 | 272 | link a "work that uses the Library" with the Library to produce a |
hudakz | 1:4f5c042a2d34 | 273 | work containing portions of the Library, and distribute that work |
hudakz | 1:4f5c042a2d34 | 274 | under terms of your choice, provided that the terms permit |
hudakz | 1:4f5c042a2d34 | 275 | modification of the work for the customer's own use and reverse |
hudakz | 1:4f5c042a2d34 | 276 | engineering for debugging such modifications. |
hudakz | 1:4f5c042a2d34 | 277 | |
hudakz | 1:4f5c042a2d34 | 278 | You must give prominent notice with each copy of the work that the |
hudakz | 1:4f5c042a2d34 | 279 | Library is used in it and that the Library and its use are covered by |
hudakz | 1:4f5c042a2d34 | 280 | this License. You must supply a copy of this License. If the work |
hudakz | 1:4f5c042a2d34 | 281 | during execution displays copyright notices, you must include the |
hudakz | 1:4f5c042a2d34 | 282 | copyright notice for the Library among them, as well as a reference |
hudakz | 1:4f5c042a2d34 | 283 | directing the user to the copy of this License. Also, you must do one |
hudakz | 1:4f5c042a2d34 | 284 | of these things: |
hudakz | 1:4f5c042a2d34 | 285 | |
hudakz | 1:4f5c042a2d34 | 286 | a) Accompany the work with the complete corresponding |
hudakz | 1:4f5c042a2d34 | 287 | machine-readable source code for the Library including whatever |
hudakz | 1:4f5c042a2d34 | 288 | changes were used in the work (which must be distributed under |
hudakz | 1:4f5c042a2d34 | 289 | Sections 1 and 2 above); and, if the work is an executable linked |
hudakz | 1:4f5c042a2d34 | 290 | with the Library, with the complete machine-readable "work that |
hudakz | 1:4f5c042a2d34 | 291 | uses the Library", as object code and/or source code, so that the |
hudakz | 1:4f5c042a2d34 | 292 | user can modify the Library and then relink to produce a modified |
hudakz | 1:4f5c042a2d34 | 293 | executable containing the modified Library. (It is understood |
hudakz | 1:4f5c042a2d34 | 294 | that the user who changes the contents of definitions files in the |
hudakz | 1:4f5c042a2d34 | 295 | Library will not necessarily be able to recompile the application |
hudakz | 1:4f5c042a2d34 | 296 | to use the modified definitions.) |
hudakz | 1:4f5c042a2d34 | 297 | |
hudakz | 1:4f5c042a2d34 | 298 | b) Use a suitable shared library mechanism for linking with the |
hudakz | 1:4f5c042a2d34 | 299 | Library. A suitable mechanism is one that (1) uses at run time a |
hudakz | 1:4f5c042a2d34 | 300 | copy of the library already present on the user's computer system, |
hudakz | 1:4f5c042a2d34 | 301 | rather than copying library functions into the executable, and (2) |
hudakz | 1:4f5c042a2d34 | 302 | will operate properly with a modified version of the library, if |
hudakz | 1:4f5c042a2d34 | 303 | the user installs one, as long as the modified version is |
hudakz | 1:4f5c042a2d34 | 304 | interface-compatible with the version that the work was made with. |
hudakz | 1:4f5c042a2d34 | 305 | |
hudakz | 1:4f5c042a2d34 | 306 | c) Accompany the work with a written offer, valid for at |
hudakz | 1:4f5c042a2d34 | 307 | least three years, to give the same user the materials |
hudakz | 1:4f5c042a2d34 | 308 | specified in Subsection 6a, above, for a charge no more |
hudakz | 1:4f5c042a2d34 | 309 | than the cost of performing this distribution. |
hudakz | 1:4f5c042a2d34 | 310 | |
hudakz | 1:4f5c042a2d34 | 311 | d) If distribution of the work is made by offering access to copy |
hudakz | 1:4f5c042a2d34 | 312 | from a designated place, offer equivalent access to copy the above |
hudakz | 1:4f5c042a2d34 | 313 | specified materials from the same place. |
hudakz | 1:4f5c042a2d34 | 314 | |
hudakz | 1:4f5c042a2d34 | 315 | e) Verify that the user has already received a copy of these |
hudakz | 1:4f5c042a2d34 | 316 | materials or that you have already sent this user a copy. |
hudakz | 1:4f5c042a2d34 | 317 | |
hudakz | 1:4f5c042a2d34 | 318 | For an executable, the required form of the "work that uses the |
hudakz | 1:4f5c042a2d34 | 319 | Library" must include any data and utility programs needed for |
hudakz | 1:4f5c042a2d34 | 320 | reproducing the executable from it. However, as a special exception, |
hudakz | 1:4f5c042a2d34 | 321 | the materials to be distributed need not include anything that is |
hudakz | 1:4f5c042a2d34 | 322 | normally distributed (in either source or binary form) with the major |
hudakz | 1:4f5c042a2d34 | 323 | components (compiler, kernel, and so on) of the operating system on |
hudakz | 1:4f5c042a2d34 | 324 | which the executable runs, unless that component itself accompanies |
hudakz | 1:4f5c042a2d34 | 325 | the executable. |
hudakz | 1:4f5c042a2d34 | 326 | |
hudakz | 1:4f5c042a2d34 | 327 | It may happen that this requirement contradicts the license |
hudakz | 1:4f5c042a2d34 | 328 | restrictions of other proprietary libraries that do not normally |
hudakz | 1:4f5c042a2d34 | 329 | accompany the operating system. Such a contradiction means you cannot |
hudakz | 1:4f5c042a2d34 | 330 | use both them and the Library together in an executable that you |
hudakz | 1:4f5c042a2d34 | 331 | distribute. |
hudakz | 1:4f5c042a2d34 | 332 | |
hudakz | 1:4f5c042a2d34 | 333 | 7. You may place library facilities that are a work based on the |
hudakz | 1:4f5c042a2d34 | 334 | Library side-by-side in a single library together with other library |
hudakz | 1:4f5c042a2d34 | 335 | facilities not covered by this License, and distribute such a combined |
hudakz | 1:4f5c042a2d34 | 336 | library, provided that the separate distribution of the work based on |
hudakz | 1:4f5c042a2d34 | 337 | the Library and of the other library facilities is otherwise |
hudakz | 1:4f5c042a2d34 | 338 | permitted, and provided that you do these two things: |
hudakz | 1:4f5c042a2d34 | 339 | |
hudakz | 1:4f5c042a2d34 | 340 | a) Accompany the combined library with a copy of the same work |
hudakz | 1:4f5c042a2d34 | 341 | based on the Library, uncombined with any other library |
hudakz | 1:4f5c042a2d34 | 342 | facilities. This must be distributed under the terms of the |
hudakz | 1:4f5c042a2d34 | 343 | Sections above. |
hudakz | 1:4f5c042a2d34 | 344 | |
hudakz | 1:4f5c042a2d34 | 345 | b) Give prominent notice with the combined library of the fact |
hudakz | 1:4f5c042a2d34 | 346 | that part of it is a work based on the Library, and explaining |
hudakz | 1:4f5c042a2d34 | 347 | where to find the accompanying uncombined form of the same work. |
hudakz | 1:4f5c042a2d34 | 348 | |
hudakz | 1:4f5c042a2d34 | 349 | 8. You may not copy, modify, sublicense, link with, or distribute |
hudakz | 1:4f5c042a2d34 | 350 | the Library except as expressly provided under this License. Any |
hudakz | 1:4f5c042a2d34 | 351 | attempt otherwise to copy, modify, sublicense, link with, or |
hudakz | 1:4f5c042a2d34 | 352 | distribute the Library is void, and will automatically terminate your |
hudakz | 1:4f5c042a2d34 | 353 | rights under this License. However, parties who have received copies, |
hudakz | 1:4f5c042a2d34 | 354 | or rights, from you under this License will not have their licenses |
hudakz | 1:4f5c042a2d34 | 355 | terminated so long as such parties remain in full compliance. |
hudakz | 1:4f5c042a2d34 | 356 | |
hudakz | 1:4f5c042a2d34 | 357 | 9. You are not required to accept this License, since you have not |
hudakz | 1:4f5c042a2d34 | 358 | signed it. However, nothing else grants you permission to modify or |
hudakz | 1:4f5c042a2d34 | 359 | distribute the Library or its derivative works. These actions are |
hudakz | 1:4f5c042a2d34 | 360 | prohibited by law if you do not accept this License. Therefore, by |
hudakz | 1:4f5c042a2d34 | 361 | modifying or distributing the Library (or any work based on the |
hudakz | 1:4f5c042a2d34 | 362 | Library), you indicate your acceptance of this License to do so, and |
hudakz | 1:4f5c042a2d34 | 363 | all its terms and conditions for copying, distributing or modifying |
hudakz | 1:4f5c042a2d34 | 364 | the Library or works based on it. |
hudakz | 1:4f5c042a2d34 | 365 | |
hudakz | 1:4f5c042a2d34 | 366 | 10. Each time you redistribute the Library (or any work based on the |
hudakz | 1:4f5c042a2d34 | 367 | Library), the recipient automatically receives a license from the |
hudakz | 1:4f5c042a2d34 | 368 | original licensor to copy, distribute, link with or modify the Library |
hudakz | 1:4f5c042a2d34 | 369 | subject to these terms and conditions. You may not impose any further |
hudakz | 1:4f5c042a2d34 | 370 | restrictions on the recipients' exercise of the rights granted herein. |
hudakz | 1:4f5c042a2d34 | 371 | You are not responsible for enforcing compliance by third parties with |
hudakz | 1:4f5c042a2d34 | 372 | this License. |
hudakz | 1:4f5c042a2d34 | 373 | |
hudakz | 1:4f5c042a2d34 | 374 | 11. If, as a consequence of a court judgment or allegation of patent |
hudakz | 1:4f5c042a2d34 | 375 | infringement or for any other reason (not limited to patent issues), |
hudakz | 1:4f5c042a2d34 | 376 | conditions are imposed on you (whether by court order, agreement or |
hudakz | 1:4f5c042a2d34 | 377 | otherwise) that contradict the conditions of this License, they do not |
hudakz | 1:4f5c042a2d34 | 378 | excuse you from the conditions of this License. If you cannot |
hudakz | 1:4f5c042a2d34 | 379 | distribute so as to satisfy simultaneously your obligations under this |
hudakz | 1:4f5c042a2d34 | 380 | License and any other pertinent obligations, then as a consequence you |
hudakz | 1:4f5c042a2d34 | 381 | may not distribute the Library at all. For example, if a patent |
hudakz | 1:4f5c042a2d34 | 382 | license would not permit royalty-free redistribution of the Library by |
hudakz | 1:4f5c042a2d34 | 383 | all those who receive copies directly or indirectly through you, then |
hudakz | 1:4f5c042a2d34 | 384 | the only way you could satisfy both it and this License would be to |
hudakz | 1:4f5c042a2d34 | 385 | refrain entirely from distribution of the Library. |
hudakz | 1:4f5c042a2d34 | 386 | |
hudakz | 1:4f5c042a2d34 | 387 | If any portion of this section is held invalid or unenforceable under any |
hudakz | 1:4f5c042a2d34 | 388 | particular circumstance, the balance of the section is intended to apply, |
hudakz | 1:4f5c042a2d34 | 389 | and the section as a whole is intended to apply in other circumstances. |
hudakz | 1:4f5c042a2d34 | 390 | |
hudakz | 1:4f5c042a2d34 | 391 | It is not the purpose of this section to induce you to infringe any |
hudakz | 1:4f5c042a2d34 | 392 | patents or other property right claims or to contest validity of any |
hudakz | 1:4f5c042a2d34 | 393 | such claims; this section has the sole purpose of protecting the |
hudakz | 1:4f5c042a2d34 | 394 | integrity of the free software distribution system which is |
hudakz | 1:4f5c042a2d34 | 395 | implemented by public license practices. Many people have made |
hudakz | 1:4f5c042a2d34 | 396 | generous contributions to the wide range of software distributed |
hudakz | 1:4f5c042a2d34 | 397 | through that system in reliance on consistent application of that |
hudakz | 1:4f5c042a2d34 | 398 | system; it is up to the author/donor to decide if he or she is willing |
hudakz | 1:4f5c042a2d34 | 399 | to distribute software through any other system and a licensee cannot |
hudakz | 1:4f5c042a2d34 | 400 | impose that choice. |
hudakz | 1:4f5c042a2d34 | 401 | |
hudakz | 1:4f5c042a2d34 | 402 | This section is intended to make thoroughly clear what is believed to |
hudakz | 1:4f5c042a2d34 | 403 | be a consequence of the rest of this License. |
hudakz | 1:4f5c042a2d34 | 404 | |
hudakz | 1:4f5c042a2d34 | 405 | 12. If the distribution and/or use of the Library is restricted in |
hudakz | 1:4f5c042a2d34 | 406 | certain countries either by patents or by copyrighted interfaces, the |
hudakz | 1:4f5c042a2d34 | 407 | original copyright holder who places the Library under this License may add |
hudakz | 1:4f5c042a2d34 | 408 | an explicit geographical distribution limitation excluding those countries, |
hudakz | 1:4f5c042a2d34 | 409 | so that distribution is permitted only in or among countries not thus |
hudakz | 1:4f5c042a2d34 | 410 | excluded. In such case, this License incorporates the limitation as if |
hudakz | 1:4f5c042a2d34 | 411 | written in the body of this License. |
hudakz | 1:4f5c042a2d34 | 412 | |
hudakz | 1:4f5c042a2d34 | 413 | 13. The Free Software Foundation may publish revised and/or new |
hudakz | 1:4f5c042a2d34 | 414 | versions of the Lesser General Public License from time to time. |
hudakz | 1:4f5c042a2d34 | 415 | Such new versions will be similar in spirit to the present version, |
hudakz | 1:4f5c042a2d34 | 416 | but may differ in detail to address new problems or concerns. |
hudakz | 1:4f5c042a2d34 | 417 | |
hudakz | 1:4f5c042a2d34 | 418 | Each version is given a distinguishing version number. If the Library |
hudakz | 1:4f5c042a2d34 | 419 | specifies a version number of this License which applies to it and |
hudakz | 1:4f5c042a2d34 | 420 | "any later version", you have the option of following the terms and |
hudakz | 1:4f5c042a2d34 | 421 | conditions either of that version or of any later version published by |
