! 30:
! 31: The licenses for most software are designed to take away your
! 32: freedom to share and change it. By contrast, the GNU General Public
! 33: License is intended to guarantee your freedom to share and change free
! 34: software---to make sure the software is free for all its users. This
! 35: General Public License applies to most of the Free Software
! 36: Foundation's software and to any other program whose authors commit to
! 37: using it. (Some other Free Software Foundation software is covered by
! 38: the GNU Library General Public License instead.) You can apply it to
! 39: your programs, too.
! 40:
! 41: When we speak of free software, we are referring to freedom, not
! 42: price. Our General Public Licenses are designed to make sure that you
! 43: have the freedom to distribute copies of free software (and charge for
! 44: this service if you wish), that you receive source code or can get it
! 45: if you want it, that you can change the software or use pieces of it
! 46: in new free programs; and that you know you can do these things.
! 47:
! 48: To protect your rights, we need to make restrictions that forbid
! 49: anyone to deny you these rights or to ask you to surrender the rights.
! 50: These restrictions translate to certain responsibilities for you if you
! 51: distribute copies of the software, or if you modify it.
! 52:
! 53: For example, if you distribute copies of such a program, whether
! 54: gratis or for a fee, you must give the recipients all the rights that
! 55: you have. You must make sure that they, too, receive or can get the
! 56: source code. And you must show them these terms so they know their
! 57: rights.
! 58:
! 59: We protect your rights with two steps: (1) copyright the software, and
! 60: (2) offer you this license which gives you legal permission to copy,
! 61: distribute and/or modify the software.
! 62:
! 63: Also, for each author's protection and ours, we want to make certain
! 64: that everyone understands that there is no warranty for this free
! 65: software. If the software is modified by someone else and passed on, we
! 66: want its recipients to know that what they have is not the original, so
! 67: that any problems introduced by others will not reflect on the original
! 68: authors' reputations.
! 69:
! 70: Finally, any free program is threatened constantly by software
! 71: patents. We wish to avoid the danger that redistributors of a free
! 72: program will individually obtain patent licenses, in effect making the
! 73: program proprietary. To prevent this, we have made it clear that any
! 74: patent must be licensed for everyone's free use or not licensed at all.
! 75:
! 76: The precise terms and conditions for copying, distribution and
! 77: modification follow.

! 84: @end ifnottex
! 85:
! 86: @enumerate 0
! 87: @item
! 88: This License applies to any program or other work which contains
! 89: a notice placed by the copyright holder saying it may be distributed
! 90: under the terms of this General Public License. The ``Program'', below,
! 91: refers to any such program or work, and a ``work based on the Program''
! 92: means either the Program or any derivative work under copyright law:
! 93: that is to say, a work containing the Program or a portion of it,
! 94: either verbatim or with modifications and/or translated into another
! 95: language. (Hereinafter, translation is included without limitation in
! 96: the term ``modification''.) Each licensee is addressed as ``you''.
! 97:
! 98: Activities other than copying, distribution and modification are not
! 99: covered by this License; they are outside its scope. The act of
! 100: running the Program is not restricted, and the output from the Program
! 101: is covered only if its contents constitute a work based on the
! 102: Program (independent of having been made by running the Program).
! 103: Whether that is true depends on what the Program does.
! 104:
! 105: @item
! 106: You may copy and distribute verbatim copies of the Program's
! 107: source code as you receive it, in any medium, provided that you
! 108: conspicuously and appropriately publish on each copy an appropriate
! 109: copyright notice and disclaimer of warranty; keep intact all the
! 110: notices that refer to this License and to the absence of any warranty;
! 111: and give any other recipients of the Program a copy of this License
! 112: along with the Program.
! 113:
! 114: You may charge a fee for the physical act of transferring a copy, and
! 115: you may at your option offer warranty protection in exchange for a fee.
! 116:
! 117: @item
! 118: 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: @enumerate a
! 124: @item
! 125: You must cause the modified files to carry prominent notices
! 126: stating that you changed the files and the date of any change.
! 127:
! 128: @item
! 129: You must cause any work that you distribute or publish, that in
! 130: whole or in part contains or is derived from the Program or any
! 131: part thereof, to be licensed as a whole at no charge to all third
! 132: parties under the terms of this License.
! 133:
! 134: @item
! 135: If the modified program normally reads commands interactively
! 136: when run, you must cause it, when started running for such
! 137: interactive use in the most ordinary way, to print or display an
! 138: announcement including an appropriate copyright notice and a
! 139: notice that there is no warranty (or else, saying that you provide
! 140: a warranty) and that users may redistribute the program under
! 141: these conditions, and telling the user how to view a copy of this
! 142: License. (Exception: if the Program itself is interactive but
! 143: does not normally print such an announcement, your work based on
! 144: the Program is not required to print an announcement.)
! 145: @end enumerate
! 146:
! 147: These requirements apply to the modified work as a whole. If
! 148: identifiable sections of that work are not derived from the Program,
! 149: and can be reasonably considered independent and separate works in
! 150: themselves, then this License, and its terms, do not apply to those
! 151: sections when you distribute them as separate works. But when you
! 152: distribute the same sections as part of a whole which is a work based
! 153: on the Program, the distribution of the whole must be on the terms of
! 154: this License, whose permissions for other licensees extend to the
! 155: entire whole, and thus to each and every part regardless of who wrote it.
! 156:
! 157: Thus, it is not the intent of this section to claim rights or contest
! 158: your rights to work written entirely by you; rather, the intent is to
! 159: exercise the right to control the distribution of derivative or
! 160: collective works based on the Program.
! 161:
! 162: In addition, mere aggregation of another work not based on the Program
! 163: with the Program (or with a work based on the Program) on a volume of
! 164: a storage or distribution medium does not bring the other work under
! 165: the scope of this License.
! 166:
! 167: @item
! 168: You may copy and distribute the Program (or a work based on it,
! 169: under Section 2) in object code or executable form under the terms of
! 170: Sections 1 and 2 above provided that you also do one of the following:
! 171:
! 172: @enumerate a
! 173: @item
! 174: Accompany it with the complete corresponding machine-readable
! 175: source code, which must be distributed under the terms of Sections
! 176: 1 and 2 above on a medium customarily used for software interchange; or,
! 177:
! 178: @item
! 179: Accompany it with a written offer, valid for at least three
! 180: years, to give any third party, for a charge no more than your
! 181: cost of physically performing source distribution, a complete
! 182: machine-readable copy of the corresponding source code, to be
! 183: distributed under the terms of Sections 1 and 2 above on a medium
! 184: customarily used for software interchange; or,
! 185:
! 186: @item
! 187: Accompany it with the information you received as to the offer
! 188: to distribute corresponding source code. (This alternative is
! 189: allowed only for noncommercial distribution and only if you
! 190: received the program in object code or executable form with such
! 191: an offer, in accord with Subsection b above.)
! 192: @end enumerate
! 193:
! 194: The source code for a work means the preferred form of the work for
! 195: making modifications to it. For an executable work, complete source
! 196: code means all the source code for all modules it contains, plus any
! 197: associated interface definition files, plus the scripts used to
! 198: control compilation and installation of the executable. However, as a
! 199: special exception, the source code distributed need not include
! 200: anything that is normally distributed (in either source or binary
! 201: form) with the major components (compiler, kernel, and so on) of the
! 202: operating system on which the executable runs, unless that component
! 203: itself accompanies the executable.
! 204:
! 205: If distribution of executable or object code is made by offering
! 206: access to copy from a designated place, then offering equivalent
! 207: access to copy the source code from the same place counts as
! 208: distribution of the source code, even though third parties are not
! 209: compelled to copy the source along with the object code.
! 210:
! 211: @item
! 212: You may not copy, modify, sublicense, or distribute the Program
! 213: except as expressly provided under this License. Any attempt
! 214: otherwise to copy, modify, sublicense or distribute the Program is
! 215: void, and will automatically terminate your rights under this License.
! 216: However, parties who have received copies, or rights, from you under
! 217: this License will not have their licenses terminated so long as such
! 218: parties remain in full compliance.
! 219:
! 220: @item
! 221: You are not required to accept this License, since you have not
! 222: signed it. However, nothing else grants you permission to modify or
! 223: distribute the Program or its derivative works. These actions are
! 224: prohibited by law if you do not accept this License. Therefore, by
! 225: modifying or distributing the Program (or any work based on the
! 226: Program), you indicate your acceptance of this License to do so, and
! 227: all its terms and conditions for copying, distributing or modifying
! 228: the Program or works based on it.
! 229:
! 230: @item
! 231: Each time you redistribute the Program (or any work based on the
! 232: Program), the recipient automatically receives a license from the
! 233: original licensor to copy, distribute or modify the Program subject to
! 234: these terms and conditions. You may not impose any further
! 235: restrictions on the recipients' exercise of the rights granted herein.
! 236: You are not responsible for enforcing compliance by third parties to
! 237: this License.
! 238:
! 239: @item
! 240: If, as a consequence of a court judgment or allegation of patent
! 241: infringement or for any other reason (not limited to patent issues),
! 242: conditions are imposed on you (whether by court order, agreement or
! 243: otherwise) that contradict the conditions of this License, they do not
! 244: excuse you from the conditions of this License. If you cannot
! 245: distribute so as to satisfy simultaneously your obligations under this
! 246: License and any other pertinent obligations, then as a consequence you
! 247: may not distribute the Program at all. For example, if a patent
! 248: license would not permit royalty-free redistribution of the Program by
! 249: all those who receive copies directly or indirectly through you, then
! 250: the only way you could satisfy both it and this License would be to
! 251: refrain entirely from distribution of the Program.
! 252:
! 253: If any portion of this section is held invalid or unenforceable under
! 254: any particular circumstance, the balance of the section is intended to
! 255: apply and the section as a whole is intended to apply in other
! 256: circumstances.
! 257:
! 258: It is not the purpose of this section to induce you to infringe any
! 259: patents or other property right claims or to contest validity of any
! 260: such claims; this section has the sole purpose of protecting the
! 261: integrity of the free software distribution system, which is
! 262: implemented by public license practices. Many people have made
! 263: generous contributions to the wide range of software distributed
! 264: through that system in reliance on consistent application of that
! 265: system; it is up to the author/donor to decide if he or she is willing
! 266: to distribute software through any other system and a licensee cannot
! 267: impose that choice.
! 268:
! 269: This section is intended to make thoroughly clear what is believed to
! 270: be a consequence of the rest of this License.
! 271:
! 272: @item
! 273: If the distribution and/or use of the Program is restricted in
! 274: certain countries either by patents or by copyrighted interfaces, the
! 275: original copyright holder who places the Program under this License
! 276: may add an explicit geographical distribution limitation excluding
! 277: those countries, so that distribution is permitted only in or among
! 278: countries not thus excluded. In such case, this License incorporates
! 279: the limitation as if written in the body of this License.
! 280:
! 281: @item
! 282: The Free Software Foundation may publish revised and/or new versions
! 283: of the General Public License from time to time. Such new versions will
! 284: be similar in spirit to the present version, but may differ in detail to
! 285: address new problems or concerns.
! 286:
! 287: Each version is given a distinguishing version number. If the Program
! 288: specifies a version number of this License which applies to it and ``any
! 289: later version'', you have the option of following the terms and conditions
! 290: either of that version or of any later version published by the Free
! 291: Software Foundation. If the Program does not specify a version number of
! 292: this License, you may choose any version ever published by the Free Software
! 293: Foundation.
! 294:
! 295: @item
! 296: If you wish to incorporate parts of the Program into other free
! 297: programs whose distribution conditions are different, write to the author
! 298: to ask for permission. For software which is copyrighted by the Free
! 299: Software Foundation, write to the Free Software Foundation; we sometimes
! 300: make exceptions for this. Our decision will be guided by the two goals
! 301: of preserving the free status of all derivatives of our free software and
! 302: of promoting the sharing and reuse of software generally.

! 343:
! 344: If you develop a new program, and you want it to be of the greatest
! 345: possible use to the public, the best way to achieve this is to make it
! 346: free software which everyone can redistribute and change under these terms.
! 347:
! 348: To do so, attach the following notices to the program. It is safest
! 349: to attach them to the start of each source file to most effectively
! 350: convey the exclusion of warranty; and each file should have at least
! 351: the ``copyright'' line and a pointer to where the full notice is found.
