1 License 2 3 ProGuard is free. You can use it freely for processing your 4 applications, commercial or not. Your code obviously remains yours 5 after having been processed, and its license can remain the same. 6 7 ProGuard itself is copyrighted, but its distribution license provides 8 you with some rights for modifying and redistributing its code and its 9 documentation. More specifically, ProGuard is distributed under the 10 terms of the GNU General Public License (GPL), version 2, as published 11 by the Free Software Foundation (FSF). In short, this means that you 12 may freely redistribute the program, modified or as is, on the 13 condition that you make the complete source code available as well. If 14 you develop a program that is linked with ProGuard, the program as a 15 whole has to be distributed at no charge under the GPL. I am granting 16 a special exception to the latter clause (in wording suggested by the 17 FSF), for combinations with the following stand-alone applications: 18 Apache Ant, Apache Maven, the Eclipse ProGuardDT GUI, the EclipseME 19 JME IDE, the Sun NetBeans Java IDE, the Sun JME Wireless Toolkit, and 20 the Javaground Tools. 21 22 The ProGuard user documentation represents an important part of this 23 work. It may only be redistributed without changes, along with the 24 unmodified version of the code. 25 26 Copyright 2002-2009 Eric Lafortune. 27 28 GNU GENERAL PUBLIC LICENSE 29 Version 2, June 1991 30 31 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 32 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA 33 Everyone is permitted to copy and distribute verbatim copies 34 of this license document, but changing it is not allowed. 35 36 Preamble 37 38 The licenses for most software are designed to take away your 39 freedom to share and change it. By contrast, the GNU General Public 40 License is intended to guarantee your freedom to share and change free 41 software--to make sure the software is free for all its users. This 42 General Public License applies to most of the Free Software 43 Foundation's software and to any other program whose authors commit to 44 using it. (Some other Free Software Foundation software is covered by 45 the GNU Library General Public License instead.) You can apply it to 46 your programs, too. 47 48 When we speak of free software, we are referring to freedom, not 49 price. Our General Public Licenses are designed to make sure that you 50 have the freedom to distribute copies of free software (and charge for 51 this service if you wish), that you receive source code or can get it 52 if you want it, that you can change the software or use pieces of it 53 in new free programs; and that you know you can do these things. 54 55 To protect your rights, we need to make restrictions that forbid 56 anyone to deny you these rights or to ask you to surrender the rights. 57 These restrictions translate to certain responsibilities for you if you 58 distribute copies of the software, or if you modify it. 59 60 For example, if you distribute copies of such a program, whether 61 gratis or for a fee, you must give the recipients all the rights that 62 you have. You must make sure that they, too, receive or can get the 63 source code. And you must show them these terms so they know their 64 rights. 65 66 We protect your rights with two steps: (1) copyright the software, and 67 (2) offer you this license which gives you legal permission to copy, 68 distribute and/or modify the software. 69 70 Also, for each author's protection and ours, we want to make certain 71 that everyone understands that there is no warranty for this free 72 software. If the software is modified by someone else and passed on, we 73 want its recipients to know that what they have is not the original, so 74 that any problems introduced by others will not reflect on the original 75 authors' reputations. 76 77 Finally, any free program is threatened constantly by software 78 patents. We wish to avoid the danger that redistributors of a free 79 program will individually obtain patent licenses, in effect making the 80 program proprietary. To prevent this, we have made it clear that any 81 patent must be licensed for everyone's free use or not licensed at all. 82 83 The precise terms and conditions for copying, distribution and 84 modification follow. 85 87 GNU GENERAL PUBLIC LICENSE 88 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 89 90 0. This License applies to any program or other work which contains 91 a notice placed by the copyright holder saying it may be distributed 92 under the terms of this General Public License. The "Program", below, 93 refers to any such program or work, and a "work based on the Program" 94 means either the Program or any derivative work under copyright law: 95 that is to say, a work containing the Program or a portion of it, 96 either verbatim or with modifications and/or translated into another 97 language. (Hereinafter, translation is included without limitation in 98 the term "modification".) Each licensee is addressed as "you". 99 100 Activities other than copying, distribution and modification are not 101 covered by this License; they are outside its scope. The act of 102 running the Program is not restricted, and the output from the Program 103 is covered only if its contents constitute a work based on the 104 Program (independent of having been made by running the Program). 105 Whether that is true depends on what the Program does. 106 107 1. You may copy and distribute verbatim copies of the Program's 108 source code as you receive it, in any medium, provided that you 109 conspicuously and appropriately publish on each copy an appropriate 110 copyright notice and disclaimer of warranty; keep intact all the 111 notices that refer to this License and to the absence of any warranty; 112 and give any other recipients of the Program a copy of this License 113 along with the Program. 114 115 You may charge a fee for the physical act of transferring a copy, and 116 you may at your option offer warranty protection in exchange for a fee. 117 118 2. You may modify your copy or copies of the Program or any portion 119 of it, thus forming a work based on the Program, and copy and 120 distribute such modifications or work under the terms of Section 1 121 above, provided that you also meet all of these conditions: 122 123 a) You must cause the modified files to carry prominent notices 124 stating that you changed the files and the date of any change. 125 126 b) You must cause any work that you distribute or publish, that in 127 whole or in part contains or is derived from the Program or any 128 part thereof, to be licensed as a whole at no charge to all third 129 parties under the terms of this License. 130 131 c) If the modified program normally reads commands interactively 132 when run, you must cause it, when started running for such 133 interactive use in the most ordinary way, to print or display an 134 announcement including an appropriate copyright notice and a 135 notice that there is no warranty (or else, saying that you provide 136 a warranty) and that users may redistribute the program under 137 these conditions, and telling the user how to view a copy of this 138 License. (Exception: if the Program itself is interactive but 139 does not normally print such an announcement, your work based on 140 the Program is not required to print an announcement.) 141 143 These requirements apply to the modified work as a whole. If 144 identifiable sections of that work are not derived from the Program, 145 and can be reasonably considered independent and separate works in 146 themselves, then this License, and its terms, do not apply to those 147 sections when you distribute them as separate works. But when you 148 distribute the same sections as part of a whole which is a work based 149 on the Program, the distribution of the whole must be on the terms of 150 this License, whose permissions for other licensees extend to the 151 entire whole, and thus to each and every part regardless of who wrote it. 152 153 Thus, it is not the intent of this section to claim rights or contest 154 your rights to work written entirely by you; rather, the intent is to 155 exercise the right to control the distribution of derivative or 156 collective works based on the Program. 157 158 In addition, mere aggregation of another work not based on the Program 159 with the Program (or with a work based on the Program) on a volume of 160 a storage or distribution medium does not bring the other work under 161 the scope of this License. 162 163 3. You may copy and distribute the Program (or a work based on it, 164 under Section 2) in object code or executable form under the terms of 165 Sections 1 and 2 above provided that you also do one of the following: 166 167 a) Accompany it with the complete corresponding machine-readable 168 source code, which must be distributed under the terms of Sections 169 1 and 2 above on a medium customarily used for software interchange; or, 170 171 b) Accompany it with a written offer, valid for at least three 172 years, to give any third party, for a charge no more than your 173 cost of physically performing source distribution, a complete 174 machine-readable copy of the corresponding source code, to be 175 distributed under the terms of Sections 1 and 2 above on a medium 176 customarily used for software interchange; or, 177 178 c) Accompany it with the information you received as to the offer 179 to distribute corresponding source code. (This alternative is 180 allowed only for noncommercial distribution and only if you 181 received the program in object code or executable form with such 182 an offer, in accord with Subsection b above.) 183 184 The source code for a work means the preferred form of the work for 185 making modifications to it. For an executable work, complete source 186 code means all the source code for all modules it contains, plus any 187 associated interface definition files, plus the scripts used to 188 control compilation and installation of the executable. However, as a 189 special exception, the source code distributed need not include 190 anything that is normally distributed (in either source or binary 191 form) with the major components (compiler, kernel, and so on) of the 192 operating system on which the executable runs, unless that component 193 itself accompanies the executable. 194 195 If distribution of executable or object code is made by offering 196 access to copy from a designated place, then offering equivalent 197 access to copy the source code from the same place counts as 198 distribution of the source code, even though third parties are not 199 compelled to copy the source along with the object code. 200 202 4. You may not copy, modify, sublicense, or distribute the Program 203 except as expressly provided under this License. Any attempt 204 otherwise to copy, modify, sublicense or distribute the Program is 205 void, and will automatically terminate your rights under this License. 206 However, parties who have received copies, or rights, from you under 207 this License will not have their licenses terminated so long as such 208 parties remain in full compliance. 209 210 5. You are not required to accept this License, since you have not 211 signed it. However, nothing else grants you permission to modify or 212 distribute the Program or its derivative works. These actions are 213 prohibited by law if you do not accept this License. Therefore, by 214 modifying or distributing the Program (or any work based on the 215 Program), you indicate your acceptance of this License to do so, and 216 all its terms and conditions for copying, distributing or modifying 217 the Program or works based on it. 218 219 6. Each time you redistribute the Program (or any work based on the 220 Program), the recipient automatically receives a license from the 221 original licensor to copy, distribute or modify the Program subject to 222 these terms and conditions. You may not impose any further 223 restrictions on the recipients' exercise of the rights granted herein. 224 You are not responsible for enforcing compliance by third parties to 225 this License. 226 227 7. If, as a consequence of a court judgment or allegation of patent 228 infringement or for any other reason (not limited to patent issues), 229 conditions are imposed on you (whether by court order, agreement or 230 otherwise) that contradict the conditions of this License, they do not 231 excuse you from the conditions of this License. If you cannot 232 distribute so as to satisfy simultaneously your obligations under this 233 License and any other pertinent obligations, then as a consequence you 234 may not distribute the Program at all. For example, if a patent 235 license would not permit royalty-free redistribution of the Program by 236 all those who receive copies directly or indirectly through you, then 237 the only way you could satisfy both it and this License would be to 238 refrain entirely from distribution of the Program. 239 240 If any portion of this section is held invalid or unenforceable under 241 any particular circumstance, the balance of the section is intended to 242 apply and the section as a whole is intended to apply in other 243 circumstances. 244 245 It is not the purpose of this section to induce you to infringe any 246 patents or other property right claims or to contest validity of any 247 such claims; this section has the sole purpose of protecting the 248 integrity of the free software distribution system, which is 249 implemented by public license practices. Many people have made 250 generous contributions to the wide range of software distributed 251 through that system in reliance on consistent application of that 252 system; it is up to the author/donor to decide if he or she is willing 253 to distribute software through any other system and a licensee cannot 254 impose that choice. 255 256 This section is intended to make thoroughly clear what is believed to 257 be a consequence of the rest of this License. 258 260 8. If the distribution and/or use of the Program is restricted in 261 certain countries either by patents or by copyrighted interfaces, the 262 original copyright holder who places the Program under this License 263 may add an explicit geographical distribution limitation excluding 264 those countries, so that distribution is permitted only in or among 265 countries not thus excluded. In such case, this License incorporates 266 the limitation as if written in the body of this License. 267 268 9. The Free Software Foundation may publish revised and/or new versions 269 of the General Public License from time to time. Such new versions will 270 be similar in spirit to the present version, but may differ in detail to 271 address new problems or concerns. 272 273 Each version is given a distinguishing version number. If the Program 274 specifies a version number of this License which applies to it and "any 275 later version", you have the option of following the terms and conditions 276 either of that version or of any later version published by the Free 277 Software Foundation. If the Program does not specify a version number of 278 this License, you may choose any version ever published by the Free Software 279 Foundation. 280 281 10. If you wish to incorporate parts of the Program into other free 282 programs whose distribution conditions are different, write to the author 283 to ask for permission. For software which is copyrighted by the Free 284 Software Foundation, write to the Free Software Foundation; we sometimes 285 make exceptions for this. Our decision will be guided by the two goals 286 of preserving the free status of all derivatives of our free software and 287 of promoting the sharing and reuse of software generally. 288 289 NO WARRANTY 290 291 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 292 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 293 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 294 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 295 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 296 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 297 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 298 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 299 REPAIR OR CORRECTION. 300 301 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 302 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 303 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 304 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 305 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 306 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 307 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 308 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 309 POSSIBILITY OF SUCH DAMAGES. 310 311 END OF TERMS AND CONDITIONS 312 314 How to Apply These Terms to Your New Programs 315 316 If you develop a new program, and you want it to be of the greatest 317 possible use to the public, the best way to achieve this is to make it 318 free software which everyone can redistribute and change under these terms. 319 320 To do so, attach the following notices to the program. It is safest 321 to attach them to the start of each source file to most effectively 322 convey the exclusion of warranty; and each file should have at least 323 the "copyright" line and a pointer to where the full notice is found. 324 325 <one line to give the program's name and a brief idea of what it does.> 326 Copyright (C) <year> <name of author> 327 328 This program is free software; you can redistribute it and/or modify 329 it under the terms of the GNU General Public License as published by 330 the Free Software Foundation; either version 2 of the License, or 331 (at your option) any later version. 332 333 This program is distributed in the hope that it will be useful, 334 but WITHOUT ANY WARRANTY; without even the implied warranty of 335 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 336 GNU General Public License for more details. 337 338 You should have received a copy of the GNU General Public License 339 along with this program; if not, write to the Free Software 340 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA 341 342 343 Also add information on how to contact you by electronic and paper mail. 344 345 If the program is interactive, make it output a short notice like this 346 when it starts in an interactive mode: 347 348 Gnomovision version 69, Copyright (C) year name of author 349 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 350 This is free software, and you are welcome to redistribute it 351 under certain conditions; type `show c' for details. 352 353 The hypothetical commands `show w' and `show c' should show the appropriate 354 parts of the General Public License. Of course, the commands you use may 355 be called something other than `show w' and `show c'; they could even be 356 mouse-clicks or menu items--whatever suits your program. 357 358 You should also get your employer (if you work as a programmer) or your 359 school, if any, to sign a "copyright disclaimer" for the program, if 360 necessary. Here is a sample; alter the names: 361 362 Yoyodyne, Inc., hereby disclaims all copyright interest in the program 363 `Gnomovision' (which makes passes at compilers) written by James Hacker. 364 365 <signature of Ty Coon>, 1 April 1989 366 Ty Coon, President of Vice 367 368 This General Public License does not permit incorporating your program into 369 proprietary programs. If your program is a subroutine library, you may 370 consider it more useful to permit linking proprietary applications with the 371 library. If this is what you want to do, use the GNU Library General 372 Public License instead of this License. 373
