joachim99@69 17
joachim99@69 18 <P>Copyright (C) 1989, 1991 Free Software Foundation, Inc.
joachim99@80 19 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA<BR>
joachim99@69 20 Everyone is permitted to copy and distribute verbatim copies
joachim99@69 21 of this license document, but changing it is not allowed.</P>
joachim99@69 22
joachim99@69 23 <H2>Preamble</H2>
joachim99@69 24
joachim99@69 25 <P>The licenses for most software are designed to take away your
joachim99@69 26 freedom to share and change it. By contrast, the GNU General Public
joachim99@69 27 License is intended to guarantee your freedom to share and change free
joachim99@69 28 software--to make sure the software is free for all its users. This
joachim99@69 29 General Public License applies to most of the Free Software
joachim99@69 30 Foundation's software and to any other program whose authors commit to
joachim99@69 31 using it. (Some other Free Software Foundation software is covered by
joachim99@69 32 the GNU Library General Public License instead.) You can apply it to
joachim99@69 33 your programs, too.</P>
joachim99@69 34
joachim99@69 35 <P>When we speak of free software, we are referring to freedom, not
joachim99@69 36 price. Our General Public Licenses are designed to make sure that you
joachim99@69 37 have the freedom to distribute copies of free software (and charge for
joachim99@69 38 this service if you wish), that you receive source code or can get it
joachim99@69 39 if you want it, that you can change the software or use pieces of it
joachim99@69 40 in new free programs; and that you know you can do these things.</P>
joachim99@69 41
joachim99@69 42 <P>To protect your rights, we need to make restrictions that forbid
joachim99@69 43 anyone to deny you these rights or to ask you to surrender the rights.
joachim99@69 44 These restrictions translate to certain responsibilities for you if you
joachim99@69 45 distribute copies of the software, or if you modify it.</P>
joachim99@69 46
joachim99@69 47 <P>For example, if you distribute copies of such a program, whether
joachim99@69 48 gratis or for a fee, you must give the recipients all the rights that
joachim99@69 49 you have. You must make sure that they, too, receive or can get the
joachim99@69 50 source code. And you must show them these terms so they know their
joachim99@69 51 rights.</P>
joachim99@69 52
joachim99@69 53 <P>We protect your rights with two steps: (1) copyright the software, and
joachim99@69 54 (2) offer you this license which gives you legal permission to copy,
joachim99@69 55 distribute and/or modify the software.</P>
joachim99@69 56
joachim99@69 57 <P>Also, for each author's protection and ours, we want to make certain
joachim99@69 58 that everyone understands that there is no warranty for this free
joachim99@69 59 software. If the software is modified by someone else and passed on, we
joachim99@69 60 want its recipients to know that what they have is not the original, so
joachim99@69 61 that any problems introduced by others will not reflect on the original
joachim99@69 62 authors' reputations.</P>
joachim99@69 63
joachim99@69 64 <P>Finally, any free program is threatened constantly by software
joachim99@69 65 patents. We wish to avoid the danger that redistributors of a free
joachim99@69 66 program will individually obtain patent licenses, in effect making the
joachim99@69 67 program proprietary. To prevent this, we have made it clear that any
joachim99@69 68 patent must be licensed for everyone's free use or not licensed at all.</P>
joachim99@69 69
joachim99@69 70 <P>The precise terms and conditions for copying, distribution and
joachim99@69 71 modification follow.</P>
joachim99@69 72
joachim99@69 73 <H2><A NAME="show-c">GNU General Public License<BR>
joachim99@69 74 Terms And Conditions For Copying, Distribution And Modification</A></H2>
joachim99@69 75
joachim99@69 76 <P>0. This License applies to any program or other work which contains
joachim99@69 77 a notice placed by the copyright holder saying it may be distributed
joachim99@69 78 under the terms of this General Public License. The "Program", below,
joachim99@69 79 refers to any such program or work, and a "work based on the Program"
joachim99@69 80 means either the Program or any derivative work under copyright law:
joachim99@69 81 that is to say, a work containing the Program or a portion of it,
joachim99@69 82 either verbatim or with modifications and/or translated into another
joachim99@69 83 language. (Hereinafter, translation is included without limitation in
joachim99@69 84 the term "modification".) Each licensee is addressed as "you".</P>
joachim99@69 85
joachim99@69 86 <P>Activities other than copying, distribution and modification are not
joachim99@69 87 covered by this License; they are outside its scope. The act of
joachim99@69 88 running the Program is not restricted, and the output from the Program
joachim99@69 89 is covered only if its contents constitute a work based on the
joachim99@69 90 Program (independent of having been made by running the Program).
joachim99@69 91 Whether that is true depends on what the Program does.</P>
joachim99@69 92
joachim99@69 93 <P>1. You may copy and distribute verbatim copies of the Program's
joachim99@69 94 source code as you receive it, in any medium, provided that you
joachim99@69 95 conspicuously and appropriately publish on each copy an appropriate
joachim99@69 96 copyright notice and disclaimer of warranty; keep intact all the
joachim99@69 97 notices that refer to this License and to the absence of any warranty;
joachim99@69 98 and give any other recipients of the Program a copy of this License
joachim99@69 99 along with the Program.</P>
joachim99@69 100
joachim99@69 101 <P>You may charge a fee for the physical act of transferring a copy, and
joachim99@69 102 you may at your option offer warranty protection in exchange for a fee.</P>
joachim99@69 103
joachim99@69 104 <P>2. You may modify your copy or copies of the Program or any portion
joachim99@69 105 of it, thus forming a work based on the Program, and copy and
joachim99@69 106 distribute such modifications or work under the terms of Section 1
joachim99@69 107 above, provided that you also meet all of these conditions:</P>
joachim99@69 108
joachim99@69 109 <OL STYLE="list-style-type: lower-alpha;">
joachim99@69 110 <LI>
joachim99@69 111 <P>You must cause the modified files to carry prominent notices
joachim99@69 112 stating that you changed the files and the date of any change.</P>
joachim99@69 113 </LI>
joachim99@69 114
joachim99@69 115 <LI>
joachim99@69 116 <P>You must cause any work that you distribute or publish, that in
joachim99@69 117 whole or in part contains or is derived from the Program or any
joachim99@69 118 part thereof, to be licensed as a whole at no charge to all third
joachim99@69 119 parties under the terms of this License.</P>
joachim99@69 120 </LI>
joachim99@69 121
joachim99@69 122 <LI>
joachim99@69 123 <P>If the modified program normally reads commands interactively
joachim99@69 124 when run, you must cause it, when started running for such
joachim99@69 125 interactive use in the most ordinary way, to print or display an
joachim99@69 126 announcement including an appropriate copyright notice and a
joachim99@69 127 notice that there is no warranty (or else, saying that you provide
joachim99@69 128 a warranty) and that users may redistribute the program under
joachim99@69 129 these conditions, and telling the user how to view a copy of this
joachim99@69 130 License. (Exception: if the Program itself is interactive but
joachim99@69 131 does not normally print such an announcement, your work based on
joachim99@69 132 the Program is not required to print an announcement.)</P>
joachim99@69 133 </LI>
joachim99@69 134 </OL>
joachim99@69 135
joachim99@69 136 <P>These requirements apply to the modified work as a whole. If
joachim99@69 137 identifiable sections of that work are not derived from the Program,
joachim99@69 138 and can be reasonably considered independent and separate works in
joachim99@69 139 themselves, then this License, and its terms, do not apply to those
joachim99@69 140 sections when you distribute them as separate works. But when you
joachim99@69 141 distribute the same sections as part of a whole which is a work based
joachim99@69 142 on the Program, the distribution of the whole must be on the terms of
joachim99@69 143 this License, whose permissions for other licensees extend to the
joachim99@69 144 entire whole, and thus to each and every part regardless of who wrote it.</P>
joachim99@69 145
joachim99@69 146 <P>Thus, it is not the intent of this section to claim rights or contest
joachim99@69 147 your rights to work written entirely by you; rather, the intent is to
joachim99@69 148 exercise the right to control the distribution of derivative or
joachim99@69 149 collective works based on the Program.</P>
joachim99@69 150
joachim99@69 151 <P>In addition, mere aggregation of another work not based on the Program
joachim99@69 152 with the Program (or with a work based on the Program) on a volume of
joachim99@69 153 a storage or distribution medium does not bring the other work under
joachim99@69 154 the scope of this License.</P>
joachim99@69 155
joachim99@69 156 <P>3. You may copy and distribute the Program (or a work based on it,
joachim99@69 157 under Section 2) in object code or executable form under the terms of
joachim99@69 158 Sections 1 and 2 above provided that you also do one of the following:</P>
joachim99@69 159
joachim99@69 160 <OL STYLE="list-style-type: lower-alpha;">
joachim99@69 161 <LI>
joachim99@69 162 <P>Accompany it with the complete corresponding machine-readable
joachim99@69 163 source code, which must be distributed under the terms of Sections
joachim99@69 164 1 and 2 above on a medium customarily used for software interchange; or,</P>
joachim99@69 165 </LI>
joachim99@69 166
joachim99@69 167 <LI>
joachim99@69 168 <P>Accompany it with a written offer, valid for at least three
joachim99@69 169 years, to give any third party, for a charge no more than your
joachim99@69 170 cost of physically performing source distribution, a complete
joachim99@69 171 machine-readable copy of the corresponding source code, to be
joachim99@69 172 distributed under the terms of Sections 1 and 2 above on a medium
joachim99@69 173 customarily used for software interchange; or,</P>
joachim99@69 174 </LI>
joachim99@69 175
joachim99@69 176 <LI>
joachim99@69 177 <P>Accompany it with the information you received as to the offer
joachim99@69 178 to distribute corresponding source code. (This alternative is
joachim99@69 179 allowed only for noncommercial distribution and only if you
joachim99@69 180 received the program in object code or executable form with such
joachim99@69 181 an offer, in accord with Subsection b above.)</P>
joachim99@69 182 </LI>
joachim99@69 183 </OL>
joachim99@69 184
joachim99@69 185 <P>The source code for a work means the preferred form of the work for
joachim99@69 186 making modifications to it. For an executable work, complete source
joachim99@69 187 code means all the source code for all modules it contains, plus any
joachim99@69 188 associated interface definition files, plus the scripts used to
joachim99@69 189 control compilation and installation of the executable. However, as a
joachim99@69 190 special exception, the source code distributed need not include
joachim99@69 191 anything that is normally distributed (in either source or binary
joachim99@69 192 form) with the major components (compiler, kernel, and so on) of the
joachim99@69 193 operating system on which the executable runs, unless that component
joachim99@69 194 itself accompanies the executable.</P>
joachim99@69 195
joachim99@69 196 <P>If distribution of executable or object code is made by offering
joachim99@69 197 access to copy from a designated place, then offering equivalent
joachim99@69 198 access to copy the source code from the same place counts as
joachim99@69 199 distribution of the source code, even though third parties are not
joachim99@69 200 compelled to copy the source along with the object code.</P>
joachim99@69 201
joachim99@69 202 <P>4. You may not copy, modify, sublicense, or distribute the Program
joachim99@69 203 except as expressly provided under this License. Any attempt
joachim99@69 204 otherwise to copy, modify, sublicense or distribute the Program is
joachim99@69 205 void, and will automatically terminate your rights under this License.
joachim99@69 206 However, parties who have received copies, or rights, from you under
joachim99@69 207 this License will not have their licenses terminated so long as such
joachim99@69 208 parties remain in full compliance.</P>
joachim99@69 209
joachim99@69 210 <P>5. You are not required to accept this License, since you have not
joachim99@69 211 signed it. However, nothing else grants you permission to modify or
joachim99@69 212 distribute the Program or its derivative works. These actions are
joachim99@69 213 prohibited by law if you do not accept this License. Therefore, by
joachim99@69 214 modifying or distributing the Program (or any work based on the
joachim99@69 215 Program), you indicate your acceptance of this License to do so, and
joachim99@69 216 all its terms and conditions for copying, distributing or modifying
joachim99@69 217 the Program or works based on it.</P>
joachim99@69 218
joachim99@69 219 <P>6. Each time you redistribute the Program (or any work based on the
joachim99@69 220 Program), the recipient automatically receives a license from the
joachim99@69 221 original licensor to copy, distribute or modify the Program subject to
joachim99@69 222 these terms and conditions. You may not impose any further
joachim99@69 223 restrictions on the recipients' exercise of the rights granted herein.
joachim99@69 224 You are not responsible for enforcing compliance by third parties to
joachim99@69 225 this License.</P>
joachim99@69 226
joachim99@69 227 <P>7. If, as a consequence of a court judgment or allegation of patent
joachim99@69 228 infringement or for any other reason (not limited to patent issues),
joachim99@69 229 conditions are imposed on you (whether by court order, agreement or
joachim99@69 230 otherwise) that contradict the conditions of this License, they do not
joachim99@69 231 excuse you from the conditions of this License. If you cannot
joachim99@69 232 distribute so as to satisfy simultaneously your obligations under this
joachim99@69 233 License and any other pertinent obligations, then as a consequence you
joachim99@69 234 may not distribute the Program at all. For example, if a patent
joachim99@69 235 license would not permit royalty-free redistribution of the Program by
joachim99@69 236 all those who receive copies directly or indirectly through you, then
joachim99@69 237 the only way you could satisfy both it and this License would be to
joachim99@69 238 refrain entirely from distribution of the Program.</P>
joachim99@69 239
joachim99@69 240 <P>If any portion of this section is held invalid or unenforceable under
joachim99@69 241 any particular circumstance, the balance of the section is intended to
joachim99@69 242 apply and the section as a whole is intended to apply in other
joachim99@69 243 circumstances.</P>
joachim99@69 244
joachim99@69 245 <P>It is not the purpose of this section to induce you to infringe any
joachim99@69 246 patents or other property right claims or to contest validity of any
joachim99@69 247 such claims; this section has the sole purpose of protecting the
joachim99@69 248 integrity of the free software distribution system, which is
joachim99@69 249 implemented by public license practices. Many people have made
joachim99@69 250 generous contributions to the wide range of software distributed
joachim99@69 251 through that system in reliance on consistent application of that
joachim99@69 252 system; it is up to the author/donor to decide if he or she is willing
joachim99@69 253 to distribute software through any other system and a licensee cannot
joachim99@69 254 impose that choice.</P>
joachim99@69 255
joachim99@69 256 <P>This section is intended to make thoroughly clear what is believed to
joachim99@69 257 be a consequence of the rest of this License.</P>
joachim99@69 258
joachim99@69 259 <P>8. If the distribution and/or use of the Program is restricted in
joachim99@69 260 certain countries either by patents or by copyrighted interfaces, the
joachim99@69 261 original copyright holder who places the Program under this License
joachim99@69 262 may add an explicit geographical distribution limitation excluding
joachim99@69 263 those countries, so that distribution is permitted only in or among
joachim99@69 264 countries not thus excluded. In such case, this License incorporates
joachim99@69 265 the limitation as if written in the body of this License.</P>
joachim99@69 266
joachim99@69 267 <P>9. The Free Software Foundation may publish revised and/or new versions
joachim99@69 268 of the General Public License from time to time. Such new versions will
joachim99@69 269 be similar in spirit to the present version, but may differ in detail to
joachim99@69 270 address new problems or concerns.</P>
joachim99@69 271
joachim99@69 272 <P>Each version is given a distinguishing version number. If the Program
joachim99@69 273 specifies a version number of this License which applies to it and "any
joachim99@69 274 later version", you have the option of following the terms and conditions
joachim99@69 275 either of that version or of any later version published by the Free
joachim99@69 276 Software Foundation. If the Program does not specify a version number of
joachim99@69 277 this License, you may choose any version ever published by the Free Software
joachim99@69 278 Foundation.</P>
joachim99@69 279
joachim99@69 280 <P>10. If you wish to incorporate parts of the Program into other free
joachim99@69 281 programs whose distribution conditions are different, write to the author
joachim99@69 282 to ask for permission. For software which is copyrighted by the Free
joachim99@69 283 Software Foundation, write to the Free Software Foundation; we sometimes
joachim99@69 284 make exceptions for this. Our decision will be guided by the two goals
joachim99@69 285 of preserving the free status of all derivatives of our free software and
joachim99@69 286 of promoting the sharing and reuse of software generally.</P>
joachim99@69 287
joachim99@69 288 <H2><A NAME="show-w">No Warranty</A></H2>
joachim99@69 289
joachim99@69 290 <P>11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
joachim99@69 291 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
joachim99@69 292 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
joachim99@69 293 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
joachim99@69 294 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
joachim99@69 295 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
joachim99@69 296 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
joachim99@69 297 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
joachim99@69 298 REPAIR OR CORRECTION.</P>
joachim99@69 299
joachim99@69 300 <P>12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
joachim99@69 301 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
joachim99@69 302 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
joachim99@69 303 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
joachim99@69 304 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
joachim99@69 305 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
joachim99@69 306 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
joachim99@69 307 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
joachim99@69 308 POSSIBILITY OF SUCH DAMAGES.</P>

joachim99@69 314 <h2>How to Apply These Terms to Your New Programs</h2>
joachim99@69 315
joachim99@69 316 <p>If you develop a new program, and you want it to be of the greatest
joachim99@69 317 possible use to the public, the best way to achieve this is to make it
joachim99@69 318 free software which everyone can redistribute and change under these
joachim99@69 319 terms.</p>
joachim99@69 320
joachim99@69 321
joachim99@69 322 <p>To do so, attach the following notices to the program. It is
joachim99@69 323 safest to attach them to the start of each source file to most
joachim99@69 324 effectively convey the exclusion of warranty; and each file should
joachim99@69 325 have at least the "copyright" line and a pointer to where the full
joachim99@69 326 notice is found.</p>
