By contrast, the GNU General Public License is 23 intended to guarantee your freedom to share and change 24 free software - to make sure the software is free for all its users. 25 This General Public License applies to most of the Free Software 26 Foundation's software and to any other program whose authors commit 27 to using it. (Some other Free Software Foundation software is covered 28 by the GNU Library General Public License instead.) You can apply it 29 to your programs, too. 30 </p><p> When we speak of free software, we are referring to freedom, not price. 31 Our General Public Licenses are designed to make sure that you have the 32 freedom to distribute copies of free software (and charge for this 33 service if you wish), that you receive source code or can get it if you 34 want it, that you can change the software or use pieces of it in new free 35 programs; and that you know you can do these things. 36 </p><p> To protect your rights, we need to make restrictions that forbid anyone 37 to deny you these rights or to ask you to surrender the rights. These 38 restrictions translate to certain responsibilities for you if you distribute 39 copies of the software, or if you modify it. 40 </p><p> For example, if you distribute copies of such a program, whether gratis or 41 for a fee, you must give the recipients all the rights that you have. You 42 must make sure that they, too, receive or can get the source code. And you 43 must show them these terms so they know their rights. 44 </p><p> We protect your rights with two steps: 45 </p><div class="orderedlist"><ol type="1"><li><p> copyright the software, and 46 </p></li><li><p> offer you this license which gives you legal permission to copy, 47 distribute and/or modify the software. 48 </p></li></ol></div><p> 49 </p><p> Also, for each author's protection and ours, we want to make certain that 50 everyone understands that there is no warranty for this free software. If 51 the software is modified by someone else and passed on, we want its 52 recipients to know that what they have is not the original, so that any 53 problems introduced by others will not reflect on the original authors' 54 reputations. 55 </p><p> Finally, any free program is threatened constantly by software patents. 56 We wish to avoid the danger that redistributors of a free program will 57 individually obtain patent licenses, in effect making the program 58 proprietary. To prevent this, we have made it clear that any patent must be 59 licensed for everyone's free use or not licensed at all. 60 </p><p> The precise terms and conditions for copying, distribution and modification 61 follow. 62 </p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="gpl-2"></a>TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</h2></div></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="gpl-2-0"></a>Section 0</h3></div></div></div><p> This License applies to any program or other work which contains a notice 63 placed by the copyright holder saying it may be distributed under the terms 64 of this General Public License. The "Program", below, refers to any such 65 program or work, and a 66 “<span class="quote"><span class="emphasis"><em>work based on the Program 67 </em></span></span>” means either 68 the Program or any derivative work under copyright law: that is to say, a 69 work containing the Program or a portion of it, either verbatim or with 70 modifications and/or translated into another language. (Hereinafter, translation 71 is included without limitation in the term 72 “<span class="quote"><span class="emphasis"><em>modification 73 </em></span></span>”.) Each licensee is addressed as “<span class="quote"><span class="emphasis"><em>you</em></span></span>”. 74 </p><p> Activities other than copying, distribution and modification are not covered by 75 this License; they are outside its scope. The act of running the Program is not 76 restricted, and the output from the Program is covered only if its contents 77 constitute a work based on the Program (independent of having been made by running 78 the Program). Whether that is true depends on what the Program does. 79 </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="gpl-2-1"></a>Section 1</h3></div></div></div><p> You may copy and distribute verbatim copies of the Program's source code as you 80 receive it, in any medium, provided that you conspicuously and appropriately 81 publish on each copy an appropriate copyright notice and disclaimer of warranty; 82 keep intact all the notices that refer to this License and to the absence of any 83 warranty; and give any other recipients of the Program a copy of this License 84 along with the Program. 85 </p><p> You may charge a fee for the physical act of transferring a copy, and you may at 86 your option offer warranty protection in exchange for a fee. 87 </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="gpl-2-2"></a>Section 2</h3></div></div></div><p> You may modify your copy or copies of the Program or any portion of it, thus 88 forming a work based on the Program, and copy and distribute such modifications 89 or work under the terms of 90 <a href="gpl.html#gpl-2-1" title="Section 1">Section 1 91 </a> above, provided 92 that you also meet all of these conditions: 93 </p><div class="orderedlist"><ol type="1"><li><p> You must cause the modified files to carry prominent notices stating that 94 you changed the files and the date of any change. 95 </p></li><li><p> You must cause any work that you distribute or publish, that in whole or 96 in part contains or is derived from the Program or any part thereof, to be 97 licensed as a whole at no charge to all third parties under the terms of 98 this License. 99 </p></li><li><p> If the modified program normally reads commands interactively when run, you 100 must cause it, when started running for such interactive use in the most 101 ordinary way, to print or display an announcement including an appropriate 102 copyright notice and a notice that there is no warranty (or else, saying 103 that you provide a warranty) and that users may redistribute the program 104 under these conditions, and telling the user how to view a copy of this 105 License. 106 </p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Exception: 107 </h3><p> If the Program itself is interactive but does not normally print such an 108 announcement, your work based on the Program is not required to print an 109 announcement.) 110 </p></div><p> 111 </p></li></ol></div><p> 112 </p><p> These requirements apply to the modified work as a whole. If identifiable sections 113 of that work are not derived from the Program, and can be reasonably considered 114 independent and separate works in themselves, then this License, and its terms, 115 do not apply to those sections when you distribute them as separate works. But when 116 you distribute the same sections as part of a whole which is a work based on the 117 Program, the distribution of the whole must be on the terms of this License, whose 118 permissions for other licensees extend to the entire whole, and thus to each and 119 every part regardless of who wrote it. 120 </p><p> Thus, it is not the intent of this section to claim rights or contest your rights 121 to work written entirely by you; rather, the intent is to exercise the right to control 122 the distribution of derivative or collective works based on the Program. 123 </p><p> In addition, mere aggregation of another work not based on the Program with the Program 124 (or with a work based on the Program) on a volume of a storage or distribution medium 125 does not bring the other work under the scope of this License. 126 </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="gpl-2-3"></a>Section 3 127 </h3></div></div></div><p> You may copy and distribute the Program (or a work based on it, under 128 <a href="gpl.html#gpl-2-2" title="Section 2">Section 2 129 </a> in object code or executable form under the terms of 130 <a href="gpl.html#gpl-2-1" title="Section 1">Sections 1 131 </a> and 132 <a href="gpl.html#gpl-2-2" title="Section 2">2 133 </a> above provided that you also do one of the following: 134 </p><div class="orderedlist"><ol type="1"><li><p> Accompany it with the complete corresponding machine-readable source code, which 135 must be distributed under the terms of Sections 1 and 2 above on a medium 136 customarily used for software interchange; or, 137 </p></li><li><p> Accompany it with a written offer, valid for at least three years, to give any 138 third party, for a charge no more than your cost of physically performing source 139 distribution, a complete machine-readable copy of the corresponding source code, 140 to be distributed under the terms of Sections 1 and 2 above on a medium customarily 141 used for software interchange; or, 142 </p></li><li><p> Accompany it with the information you received as to the offer to distribute 143 corresponding source code. (This alternative is allowed only for noncommercial 144 distribution and only if you received the program in object code or executable form 145 with such an offer, in accord with Subsection b above.) 146 </p></li></ol></div><p> 147 </p><p> The source code for a work means the preferred form of the work for making modifications 148 to it. For an executable work, complete source code means all the source code for all modules 149 it contains, plus any associated interface definition files, plus the scripts used to control 150 compilation and installation of the executable. However, as a special exception, the source 151 code distributed need not include anything that is normally distributed (in either source or 152 binary form) with the major components (compiler, kernel, and so on) of the operating system 153 on which the executable runs, unless that component itself accompanies the executable. 154 </p><p> If distribution of executable or object code is made by offering access to copy from a 155 designated place, then offering equivalent access to copy the source code from the same place 156 counts as distribution of the source code, even though third parties are not compelled to 157 copy the source along with the object code. 158 </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="gpl-2-4"></a>Section 4 159 </h3></div></div></div><p> You may not copy, modify, sublicense, or distribute the Program except as expressly provided 160 under this License. Any attempt otherwise to copy, modify, sublicense or distribute the 161 Program is void, and will automatically terminate your rights under this License. However, 162 parties who have received copies, or rights, from you under this License will not have their 163 licenses terminated so long as such parties remain in full compliance. 164 </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="gpl-2-5"></a>Section 5 165 </h3></div></div></div><p> You are not required to accept this License, since you have not signed it. However, nothing 166 else grants you permission to modify or distribute the Program or its derivative works. 167 These actions are prohibited by law if you do not accept this License. Therefore, by modifying 168 or distributing the Program (or any work based on the Program), you indicate your acceptance 169 of this License to do so, and all its terms and conditions for copying, distributing or 170 modifying the Program or works based on it. 171 </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="gpl-2-6"></a>Section 6 172 </h3></div></div></div><p> Each time you redistribute the Program (or any work based on the Program), the recipient 173 automatically receives a license from the original licensor to copy, distribute or modify 174 the Program subject to these terms and conditions. You may not impose any further restrictions 175 on the recipients' exercise of the rights granted herein. You are not responsible for enforcing 176 compliance by third parties to this License. 177 </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="gpl-2-7"></a>Section 7 178 </h3></div></div></div><p> If, as a consequence of a court judgment or allegation of patent infringement or for any other 179 reason (not limited to patent issues), conditions are imposed on you (whether by court order, 180 agreement or otherwise) that contradict the conditions of this License, they do not excuse you 181 from the conditions of this License. If you cannot distribute so as to satisfy simultaneously 182 your obligations under this License and any other pertinent obligations, then as a consequence 183 you may not distribute the Program at all. For example, if a patent license would not permit 184 royalty-free redistribution of the Program by all those who receive copies directly or 185 indirectly through you, then the only way you could satisfy both it and this License would be 186 to refrain entirely from distribution of the Program. 187 </p><p> If any portion of this section is held invalid or unenforceable under any particular circumstance, 188 the balance of the section is intended to apply and the section as a whole is intended to apply 189 in other circumstances. 190 </p><p> It is not the purpose of this section to induce you to infringe any patents or other property 191 right claims or to contest validity of any such claims; this section has the sole purpose of 192 protecting the integrity of the free software distribution system, which is implemented by public 193 license practices. Many people have made generous contributions to the wide range of software 194 distributed through that system in reliance on consistent application of that system; it is up 195 to the author/donor to decide if he or she is willing to distribute software through any other 196 system and a licensee cannot impose that choice. 197 </p><p> This section is intended to make thoroughly clear what is believed to be a consequence of the 198 rest of this License. 199 </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="gpl-2-8"></a>Section 8 200 </h3></div></div></div><p> If the distribution and/or use of the Program is restricted in certain countries either by patents 201 or by copyrighted interfaces, the original copyright holder who places the Program under this License 202 may add an explicit geographical distribution limitation excluding those countries, so that 203 distribution is permitted only in or among countries not thus excluded. In such case, this License 204 incorporates the limitation as if written in the body of this License. 205 </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="gpl-2-9"></a>Section 9 206 </h3></div></div></div><p> The Free Software Foundation may publish revised and/or new versions of the General Public License 207 from time to time. Such new versions will be similar in spirit to the present version, but may differ 208 in detail to address new problems or concerns. 209 </p><p> Each version is given a distinguishing version number. If the Program specifies a version number of 210 this License which applies to it and "any later version", you have the option of following the terms 211 and conditions either of that version or of any later version published by the Free Software 212 Foundation. If the Program does not specify a version number of this License, you may choose any 213 version ever published by the Free Software Foundation. 214 </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="gpl-2-10"></a>Section 10 215 </h3></div></div></div><p> If you wish to incorporate parts of the Program into other free programs whose distribution 216 conditions are different, write to the author to ask for permission. For software which is copyrighted 217 by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions 218 for this. Our decision will be guided by the two goals of preserving the free status of all 219 derivatives of our free software and of promoting the sharing and reuse of software generally. 220 </p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="gpl-2-11"></a>NO WARRANTY Section 11 221 </h3></div></div></div><p> BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT 222 PERMITTED BY APPLICABLE LAW.

It is safest 243 to attach them to the start of each source file to most effectively 244 convey the exclusion of warranty; and each file should have at least 245 the "copyright" line and a pointer to where the full notice is found. 246 </p><p> 247 <one line to give the program's name and a brief idea of what it does.> 248 Copyright (C) <year> <name of author> 249 </p><p> 250 This program is free software; you can redistribute it and/or modify 251 it under the terms of the GNU General Public License as published by 252 the Free Software Foundation; either version 2 of the License, or 253 (at your option) any later version. 254 </p><p> 255 This program is distributed in the hope that it will be useful, 256 but WITHOUT ANY WARRANTY; without even the implied warranty of 257 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
