! 5: 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
! 6: Everyone is permitted to copy and distribute verbatim copies
! 7: of this license document, but changing it is not allowed.
! 8:
! 9: Preamble
! 10:
! 11: The licenses for most software are designed to take away your
! 12: freedom to share and change it. By contrast, the GNU General Public
! 13: License is intended to guarantee your freedom to share and change free
! 14: software--to make sure the software is free for all its users. This
! 15: General Public License applies to most of the Free Software
! 16: Foundation's software and to any other program whose authors commit to
! 17: using it. (Some other Free Software Foundation software is covered by
! 18: the GNU Lesser General Public License instead.) You can apply it to
! 19: your programs, too.
! 20:
! 21: When we speak of free software, we are referring to freedom, not
! 22: price. Our General Public Licenses are designed to make sure that you
! 23: have the freedom to distribute copies of free software (and charge for
! 24: this service if you wish), that you receive source code or can get it
! 25: if you want it, that you can change the software or use pieces of it
! 26: in new free programs; and that you know you can do these things.
! 27:
! 28: To protect your rights, we need to make restrictions that forbid
! 29: anyone to deny you these rights or to ask you to surrender the rights.
! 30: These restrictions translate to certain responsibilities for you if you
! 31: distribute copies of the software, or if you modify it.
! 32:
! 33: For example, if you distribute copies of such a program, whether
! 34: gratis or for a fee, you must give the recipients all the rights that
! 35: you have. You must make sure that they, too, receive or can get the
! 36: source code. And you must show them these terms so they know their
! 37: rights.
! 38:
! 39: We protect your rights with two steps: (1) copyright the software, and
! 40: (2) offer you this license which gives you legal permission to copy,
! 41: distribute and/or modify the software.
! 42:
! 43: Also, for each author's protection and ours, we want to make certain
! 44: that everyone understands that there is no warranty for this free
! 45: software. If the software is modified by someone else and passed on, we
! 46: want its recipients to know that what they have is not the original, so
! 47: that any problems introduced by others will not reflect on the original
! 48: authors' reputations.
! 49:
! 50: Finally, any free program is threatened constantly by software
! 51: patents. We wish to avoid the danger that redistributors of a free
! 52: program will individually obtain patent licenses, in effect making the
! 53: program proprietary. To prevent this, we have made it clear that any
! 54: patent must be licensed for everyone's free use or not licensed at all.
! 55:
! 56: The precise terms and conditions for copying, distribution and
! 57: modification follow.
! 58:
! 59: GNU GENERAL PUBLIC LICENSE
! 60: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
! 61:
! 62: 0. This License applies to any program or other work which contains
! 63: a notice placed by the copyright holder saying it may be distributed
! 64: under the terms of this General Public License. The "Program", below,
! 65: refers to any such program or work, and a "work based on the Program"
! 66: means either the Program or any derivative work under copyright law:
! 67: that is to say, a work containing the Program or a portion of it,
! 68: either verbatim or with modifications and/or translated into another
! 69: language. (Hereinafter, translation is included without limitation in
! 70: the term "modification".) Each licensee is addressed as "you".
! 71:
! 72: Activities other than copying, distribution and modification are not
! 73: covered by this License; they are outside its scope. The act of
! 74: running the Program is not restricted, and the output from the Program
! 75: is covered only if its contents constitute a work based on the
! 76: Program (independent of having been made by running the Program).
! 77: Whether that is true depends on what the Program does.
! 78:
! 79: 1. You may copy and distribute verbatim copies of the Program's
! 80: source code as you receive it, in any medium, provided that you
! 81: conspicuously and appropriately publish on each copy an appropriate
! 82: copyright notice and disclaimer of warranty; keep intact all the
! 83: notices that refer to this License and to the absence of any warranty;
! 84: and give any other recipients of the Program a copy of this License
! 85: along with the Program.
! 86:
! 87: You may charge a fee for the physical act of transferring a copy, and
! 88: you may at your option offer warranty protection in exchange for a fee.
! 89:
! 90: 2. You may modify your copy or copies of the Program or any portion
! 91: of it, thus forming a work based on the Program, and copy and
! 92: distribute such modifications or work under the terms of Section 1
! 93: above, provided that you also meet all of these conditions:
! 94:
! 95: a) You must cause the modified files to carry prominent notices
! 96: stating that you changed the files and the date of any change.
! 97:
! 98: b) You must cause any work that you distribute or publish, that in
! 99: whole or in part contains or is derived from the Program or any
! 100: part thereof, to be licensed as a whole at no charge to all third
! 101: parties under the terms of this License.
! 102:
! 103: c) If the modified program normally reads commands interactively
! 104: when run, you must cause it, when started running for such
! 105: interactive use in the most ordinary way, to print or display an
! 106: announcement including an appropriate copyright notice and a
! 107: notice that there is no warranty (or else, saying that you provide
! 108: a warranty) and that users may redistribute the program under
! 109: these conditions, and telling the user how to view a copy of this
! 110: License. (Exception: if the Program itself is interactive but
! 111: does not normally print such an announcement, your work based on
! 112: the Program is not required to print an announcement.)
! 113:
! 114: These requirements apply to the modified work as a whole. If
! 115: identifiable sections of that work are not derived from the Program,
! 116: and can be reasonably considered independent and separate works in
! 117: themselves, then this License, and its terms, do not apply to those
! 118: sections when you distribute them as separate works. But when you
! 119: distribute the same sections as part of a whole which is a work based
! 120: on the Program, the distribution of the whole must be on the terms of
! 121: this License, whose permissions for other licensees extend to the
! 122: entire whole, and thus to each and every part regardless of who wrote it.
! 123:
! 124: Thus, it is not the intent of this section to claim rights or contest
! 125: your rights to work written entirely by you; rather, the intent is to
! 126: exercise the right to control the distribution of derivative or
! 127: collective works based on the Program.
! 128:
! 129: In addition, mere aggregation of another work not based on the Program
! 130: with the Program (or with a work based on the Program) on a volume of
! 131: a storage or distribution medium does not bring the other work under
! 132: the scope of this License.
! 133:
! 134: 3. You may copy and distribute the Program (or a work based on it,
! 135: under Section 2) in object code or executable form under the terms of
! 136: Sections 1 and 2 above provided that you also do one of the following:
! 137:
! 138: a) Accompany it with the complete corresponding machine-readable
! 139: source code, which must be distributed under the terms of Sections
! 140: 1 and 2 above on a medium customarily used for software interchange; or,
! 141:
! 142: b) Accompany it with a written offer, valid for at least three
! 143: years, to give any third party, for a charge no more than your
! 144: cost of physically performing source distribution, a complete
! 145: machine-readable copy of the corresponding source code, to be
! 146: distributed under the terms of Sections 1 and 2 above on a medium
! 147: customarily used for software interchange; or,
! 148:
! 149: c) Accompany it with the information you received as to the offer
! 150: to distribute corresponding source code. (This alternative is
! 151: allowed only for noncommercial distribution and only if you
! 152: received the program in object code or executable form with such
! 153: an offer, in accord with Subsection b above.)
! 154:
! 155: The source code for a work means the preferred form of the work for
! 156: making modifications to it. For an executable work, complete source
! 157: code means all the source code for all modules it contains, plus any
! 158: associated interface definition files, plus the scripts used to
! 159: control compilation and installation of the executable. However, as a
! 160: special exception, the source code distributed need not include
! 161: anything that is normally distributed (in either source or binary
! 162: form) with the major components (compiler, kernel, and so on) of the
! 163: operating system on which the executable runs, unless that component
! 164: itself accompanies the executable.
! 165:
! 166: If distribution of executable or object code is made by offering
! 167: access to copy from a designated place, then offering equivalent
! 168: access to copy the source code from the same place counts as
! 169: distribution of the source code, even though third parties are not
! 170: compelled to copy the source along with the object code.
! 171:
! 172: 4. You may not copy, modify, sublicense, or distribute the Program
! 173: except as expressly provided under this License. Any attempt
! 174: otherwise to copy, modify, sublicense or distribute the Program is
! 175: void, and will automatically terminate your rights under this License.
! 176: However, parties who have received copies, or rights, from you under
! 177: this License will not have their licenses terminated so long as such
! 178: parties remain in full compliance.
! 179:
! 180: 5. You are not required to accept this License, since you have not
! 181: signed it. However, nothing else grants you permission to modify or
! 182: distribute the Program or its derivative works. These actions are
! 183: prohibited by law if you do not accept this License. Therefore, by
! 184: modifying or distributing the Program (or any work based on the
! 185: Program), you indicate your acceptance of this License to do so, and
! 186: all its terms and conditions for copying, distributing or modifying
! 187: the Program or works based on it.
! 188:
! 189: 6. Each time you redistribute the Program (or any work based on the
! 190: Program), the recipient automatically receives a license from the
! 191: original licensor to copy, distribute or modify the Program subject to
! 192: these terms and conditions. You may not impose any further
! 193: restrictions on the recipients' exercise of the rights granted herein.
! 194: You are not responsible for enforcing compliance by third parties to
! 195: this License.
! 196:
! 197: 7. If, as a consequence of a court judgment or allegation of patent
! 198: infringement or for any other reason (not limited to patent issues),
! 199: conditions are imposed on you (whether by court order, agreement or
! 200: otherwise) that contradict the conditions of this License, they do not
! 201: excuse you from the conditions of this License. If you cannot
! 202: distribute so as to satisfy simultaneously your obligations under this
! 203: License and any other pertinent obligations, then as a consequence you
! 204: may not distribute the Program at all. For example, if a patent
! 205: license would not permit royalty-free redistribution of the Program by
! 206: all those who receive copies directly or indirectly through you, then
! 207: the only way you could satisfy both it and this License would be to
! 208: refrain entirely from distribution of the Program.
! 209:
! 210: If any portion of this section is held invalid or unenforceable under
! 211: any particular circumstance, the balance of the section is intended to
! 212: apply and the section as a whole is intended to apply in other
! 213: circumstances.
! 214:
! 215: It is not the purpose of this section to induce you to infringe any
! 216: patents or other property right claims or to contest validity of any
! 217: such claims; this section has the sole purpose of protecting the
! 218: integrity of the free software distribution system, which is
! 219: implemented by public license practices. Many people have made
! 220: generous contributions to the wide range of software distributed
! 221: through that system in reliance on consistent application of that
! 222: system; it is up to the author/donor to decide if he or she is willing
! 223: to distribute software through any other system and a licensee cannot
! 224: impose that choice.
! 225:
! 226: This section is intended to make thoroughly clear what is believed to
! 227: be a consequence of the rest of this License.
! 228:
! 229: 8. If the distribution and/or use of the Program is restricted in
! 230: certain countries either by patents or by copyrighted interfaces, the
! 231: original copyright holder who places the Program under this License
! 232: may add an explicit geographical distribution limitation excluding
! 233: those countries, so that distribution is permitted only in or among
! 234: countries not thus excluded. In such case, this License incorporates
! 235: the limitation as if written in the body of this License.
! 236:
! 237: 9. The Free Software Foundation may publish revised and/or new versions
! 238: of the General Public License from time to time. Such new versions will
! 239: be similar in spirit to the present version, but may differ in detail to
! 240: address new problems or concerns.
! 241:
! 242: Each version is given a distinguishing version number. If the Program
! 243: specifies a version number of this License which applies to it and "any
! 244: later version", you have the option of following the terms and conditions
! 245: either of that version or of any later version published by the Free
! 246: Software Foundation. If the Program does not specify a version number of
! 247: this License, you may choose any version ever published by the Free Software
! 248: Foundation.
! 249:
! 250: 10. If you wish to incorporate parts of the Program into other free
! 251: programs whose distribution conditions are different, write to the author
! 252: to ask for permission. For software which is copyrighted by the Free
! 253: Software Foundation, write to the Free Software Foundation; we sometimes
! 254: make exceptions for this. Our decision will be guided by the two goals
! 255: of preserving the free status of all derivatives of our free software and
! 256: of promoting the sharing and reuse of software generally.
! 257:
! 258: NO WARRANTY
! 259:
! 260: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
! 261: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
! 262: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
! 263: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
! 264: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
! 265: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
! 266: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
! 267: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
! 268: REPAIR OR CORRECTION.
! 269:
! 270: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
! 271: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
! 272: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
! 273: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
! 274: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
! 275: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
! 276: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
! 277: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
! 278: POSSIBILITY OF SUCH DAMAGES.
! 279:
! 280: END OF TERMS AND CONDITIONS
! 281:
! 282: How to Apply These Terms to Your New Programs
! 283:
! 284: If you develop a new program, and you want it to be of the greatest
! 285: possible use to the public, the best way to achieve this is to make it
! 286: free software which everyone can redistribute and change under these terms.
! 287:
! 288: To do so, attach the following notices to the program. It is safest
! 289: to attach them to the start of each source file to most effectively
! 290: convey the exclusion of warranty; and each file should have at least
! 291: the "copyright" line and a pointer to where the full notice is found.
! 292:
! 293: <one line to give the program's name and a brief idea of what it does.>
! 294: Copyright (C) <year> <name of author>
! 295:
! 296: This program is free software; you can redistribute it and/or modify
! 297: it under the terms of the GNU General Public License as published by
! 298: the Free Software Foundation; either version 2 of the License, or
! 299: (at your option) any later version.
! 300:
! 301: This program is distributed in the hope that it will be useful,
! 302: but WITHOUT ANY WARRANTY; without even the implied warranty of
! 303: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
! 304: GNU General Public License for more details.
! 305:
! 306: You should have received a copy of the GNU General Public License along
! 307: with this program; if not, write to the Free Software Foundation, Inc.,
! 308: 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
! 309:
! 310: Also add information on how to contact you by electronic and paper mail.
! 311:
! 312: If the program is interactive, make it output a short notice like this
! 313: when it starts in an interactive mode:
! 314:
! 315: Gnomovision version 69, Copyright (C) year name of author
! 316: Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
! 317: This is free software, and you are welcome to redistribute it
! 318: under certain conditions; type `show c' for details.
! 319:
! 320: The hypothetical commands `show w' and `show c' should show the appropriate
! 321: parts of the General Public License. Of course, the commands you use may
! 322: be called something other than `show w' and `show c'; they could even be
! 323: mouse-clicks or menu items--whatever suits your program.
! 324:
! 325: You should also get your employer (if you work as a programmer) or your
! 326: school, if any, to sign a "copyright disclaimer" for the program, if
! 327: necessary. Here is a sample; alter the names:
! 328:
! 329: Yoyodyne, Inc., hereby disclaims all copyright interest in the program
! 330: `Gnomovision' (which makes passes at compilers) written by James Hacker.
! 331:
! 332: <signature of Ty Coon>, 1 April 1989
! 333: Ty Coon, President of Vice
! 334:
! 335: This General Public License does not permit incorporating your program into
! 336: proprietary programs. If your program is a subroutine library, you may
! 337: consider it more useful to permit linking proprietary applications with the
! 338: library. If this is what you want to do, use the GNU Lesser General
! 339: Public License instead of this License.
