Chris@2 1 GNU GENERAL PUBLIC LICENSE
Chris@2 2 Version 2, June 1991
Chris@2 3

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