  18 <H3>Introduction</H3>
  19
  20 <P>The Common UNIX Printing System<SUP>TM</SUP>, ("CUPS<SUP>TM</SUP>"),
  21 is provided under the GNU General Public License ("GPL") and GNU
  22 Library General Public License ("LGPL"), Version 2. A copy of these
  23 licenses follow this introduction.
  24
  25 <P>The GNU LGPL applies to the CUPS API library, located in the "cups"
  26 subdirectory of the CUPS source distribution and in the
  27 "/usr/include/cups" directory and "libcups.a", "libcups.sl", or
  28 "libcups.so" files in the binary distributions.
  29
  30 <P>The GNU GPL applies to the remainder of the CUPS distribution,
  31 including the "pstoraster" filter which is based upon GNU Ghostscript
  32 5.50 and the "pdftops" filter which is based upon Xpdf 0.92.
  33
  34 <P>For those not familiar with the GNU GPL, the license basically
  35 allows you to:
  36
  37 <UL>
  38
  39         <LI>Use the CUPS software at no charge.
  40
  41         <LI>Distribute verbatim copies of the software in source or
  42         binary form.
  43
  44         <LI>Sell verbatim copies of the software for a media fee, or
  45         sell support for the software.
  46
  47         <LI>Distribute or sell printer drivers and filters that use
  48         CUPS so long as source code is made available under the GPL.
  49
  50 </UL>
  51
  52 <P>What this license <B>does not</B> allow you to do is make changes or
  53 add features to CUPS and then sell a binary distribution without source
  54 code. You must provide source for any new drivers, changes, or
  55 additions to the software, and all code must be provided under the GPL
  56 or LGPL as appropriate.
  57
  58 <P>The GNU LGPL relaxes the "link-to" restriction, allowing you to
  59 develop applications that use the CUPS API library under other licenses
  60 and/or conditions as appropriate for your application.
  61
  62 <H3>Trademarks</H3>
  63
  64 <P>Easy Software Products has trademarked the Common UNIX Printing
  65 System, CUPS, and CUPS logo. These names and logos may be used freely
  66 in any direct port or binary distribution of CUPS. To use them in
  67 derivative products, please contract Easy Software Products for written
  68 permission. Our intention is to protect the value of these trademarks and
  69 ensure that any derivative product meets the same high-quality
  70 standards as the original.
  71
  72 <H3>Binary Distribution Rights</H3>
  73
  74 <P>Easy Software Products also sells rights to the CUPS source code
  75 under a binary distribution license for vendors that are unable to
  76 release source code for their drivers, additions, and modifications to
  77 CUPS under the GNU GPL and LGPL. For information please contact us at
  78 the address shown above.
  79
  80 <P>The Common UNIX Printing System provides a "pstoraster" filter that
  81 utilizes the GNU GhostScript 5.50 core to convert PostScript files into
  82 a stream of raster images. For binary distribution licensing of this
  83 software, please contact:

 120 <PRE>
 121 Copyright 1989, 1991 Free Software Foundation, Inc.
 122 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
 123
 124 Everyone is permitted to copy and distribute verbatim
 125 copies of this license document, but changing it is not allowed.
 126 <PRE>
 127
 128 <H4>Preamble</H4>
 129
 130 <P>The licenses for most software are designed to take away your
 131 freedom to share and change it.  By contrast, the GNU General Public
 132 License is intended to guarantee your freedom to share and change free
 133 software--to make sure the software is free for all its users.  This
 134 General Public License applies to most of the Free Software
 135 Foundation's software and to any other program whose authors commit to
 136 using it.  (Some other Free Software Foundation software is covered by
 137 the GNU Library General Public License instead.)  You can apply it to
 138 your programs, too.
 139
 140 <P>When we speak of free software, we are referring to freedom, not
 141 price.  Our General Public Licenses are designed to make sure that you
 142 have the freedom to distribute copies of free software (and charge for
 143 this service if you wish), that you receive source code or can get it
 144 if you want it, that you can change the software or use pieces of it
 145 in new free programs; and that you know you can do these things.
 146
 147 <P>To protect your rights, we need to make restrictions that forbid
 148 anyone to deny you these rights or to ask you to surrender the rights.
 149 These restrictions translate to certain responsibilities for you if you
 150 distribute copies of the software, or if you modify it.
 151
 152 <P>For example, if you distribute copies of such a program, whether
 153 gratis or for a fee, you must give the recipients all the rights that
 154 you have.  You must make sure that they, too, receive or can get the
 155 source code.  And you must show them these terms so they know their
 156 rights.
 157
 158 <P>We protect your rights with two steps: (1) copyright the software, and
 159 (2) offer you this license which gives you legal permission to copy,
 160 distribute and/or modify the software.
 161
 162 <P>Also, for each author's protection and ours, we want to make certain
 163 that everyone understands that there is no warranty for this free
 164 software.  If the software is modified by someone else and passed on, we
 165 want its recipients to know that what they have is not the original, so
 166 that any problems introduced by others will not reflect on the original
 167 authors' reputations.
 168
 169 <P>Finally, any free program is threatened constantly by software
 170 patents.  We wish to avoid the danger that redistributors of a free
 171 program will individually obtain patent licenses, in effect making the
 172 program proprietary.  To prevent this, we have made it clear that any
 173 patent must be licensed for everyone's free use or not licensed at all.
 174
 175 <P>The precise terms and conditions for copying, distribution and
 176 modification follow.
 177
 178 <H4>GNU GENERAL PUBLIC LICENSE<BR>
 179 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</H4>
 180
 181 <OL START="0">
 182
 183 <LI>This License applies to any program or other work which contains
 184 a notice placed by the copyright holder saying it may be distributed
 185 under the terms of this General Public License.  The "Program", below,
 186 refers to any such program or work, and a "work based on the Program"
 187 means either the Program or any derivative work under copyright law:
 188 that is to say, a work containing the Program or a portion of it,
 189 either verbatim or with modifications and/or translated into another
 190 language.  (Hereinafter, translation is included without limitation in
 191 the term "modification".)  Each licensee is addressed as "you".
 192
 193 <P>Activities other than copying, distribution and modification are not
 194 covered by this License; they are outside its scope.  The act of
 195 running the Program is not restricted, and the output from the Program
 196 is covered only if its contents constitute a work based on the
 197 Program (independent of having been made by running the Program).
 198 Whether that is true depends on what the Program does.
 199
 200 <LI>You may copy and distribute verbatim copies of the Program's
 201 source code as you receive it, in any medium, provided that you
 202 conspicuously and appropriately publish on each copy an appropriate
 203 copyright notice and disclaimer of warranty; keep intact all the
 204 notices that refer to this License and to the absence of any warranty;
 205 and give any other recipients of the Program a copy of this License
 206 along with the Program.
 207
 208 <P>You may charge a fee for the physical act of transferring a copy, and
 209 you may at your option offer warranty protection in exchange for a fee.
 210
 211 <LI>You may modify your copy or copies of the Program or any portion
 212 of it, thus forming a work based on the Program, and copy and
 213 distribute such modifications or work under the terms of Section 1
 214 above, provided that you also meet all of these conditions:
 215
 216 <OL TYPE="a">
 217
 218 <LI>You must cause the modified files to carry prominent notices
 219 stating that you changed the files and the date of any change.
 220
 221 <LI>You must cause any work that you distribute or publish, that in
 222 whole or in part contains or is derived from the Program or any
 223 part thereof, to be licensed as a whole at no charge to all third
 224 parties under the terms of this License.
 225
 226 <LI>if the modified program normally reads commands interactively
 227 when run, you must cause it, when started running for such
 228 interactive use in the most ordinary way, to print or display an
 229 announcement including an appropriate copyright notice and a
 230 notice that there is no warranty (or else, saying that you provide
 231 a warranty) and that users may redistribute the program under
 232 these conditions, and telling the user how to view a copy of this
 233 License.  (Exception: if the Program itself is interactive but
 234 does not normally print such an announcement, your work based on
 235 the Program is not required to print an announcement.)
 236
 237 </OL>
 238
 239 <P>These requirements apply to the modified work as a whole.  If
 240 identifiable sections of that work are not derived from the Program,
 241 and can be reasonably considered independent and separate works in
 242 themselves, then this License, and its terms, do not apply to those
 243 sections when you distribute them as separate works.  But when you
 244 distribute the same sections as part of a whole which is a work based
 245 on the Program, the distribution of the whole must be on the terms of
 246 this License, whose permissions for other licensees extend to the
 247 entire whole, and thus to each and every part regardless of who wrote it.
 248
 249 <P>Thus, it is not the intent of this section to claim rights or contest
 250 your rights to work written entirely by you; rather, the intent is to
 251 exercise the right to control the distribution of derivative or
 252 collective works based on the Program.
 253
 254 <P>In addition, mere aggregation of another work not based on the Program
 255 with the Program (or with a work based on the Program) on a volume of
 256 a storage or distribution medium does not bring the other work under
 257 the scope of this License.
 258
 259 <LI>You may copy and distribute the Program (or a work based on it,
 260 under Section 2) in object code or executable form under the terms of
 261 Sections 1 and 2 above provided that you also do one of the following:
 262
 263 <OL TYPE="a">
 264
 265 <LI>Accompany it with the complete corresponding machine-readable
 266 source code, which must be distributed under the terms of Sections
 267 1 and 2 above on a medium customarily used for software interchange; or,
 268
 269 <LI>Accompany it with a written offer, valid for at least three
 270 years, to give any third party, for a charge no more than your
 271 cost of physically performing source distribution, a complete
 272 machine-readable copy of the corresponding source code, to be
 273 distributed under the terms of Sections 1 and 2 above on a medium
 274 customarily used for software interchange; or,
 275
 276 <LI>Accompany it with the information you received as to the offer
 277 to distribute corresponding source code.  (This alternative is
 278 allowed only for noncommercial distribution and only if you
 279 received the program in object code or executable form with such
 280 an offer, in accord with Subsection b above.)
 281
 282 </OL>
 283
 284 <P>The source code for a work means the preferred form of the work for
 285 making modifications to it.  For an executable work, complete source
 286 code means all the source code for all modules it contains, plus any
 287 associated interface definition files, plus the scripts used to
 288 control compilation and installation of the executable.  However, as a
 289 special exception, the source code distributed need not include
 290 anything that is normally distributed (in either source or binary
 291 form) with the major components (compiler, kernel, and so on) of the
 292 operating system on which the executable runs, unless that component
 293 itself accompanies the executable.
 294
 295 <P>If distribution of executable or object code is made by offering
 296 access to copy from a designated place, then offering equivalent
 297 access to copy the source code from the same place counts as
 298 distribution of the source code, even though third parties are not
 299 compelled to copy the source along with the object code.
 300
 301 <LI>You may not copy, modify, sublicense, or distribute the Program
 302 except as expressly provided under this License.  Any attempt
 303 otherwise to copy, modify, sublicense or distribute the Program is
 304 void, and will automatically terminate your rights under this License.
 305 However, parties who have received copies, or rights, from you under
 306 this License will not have their licenses terminated so long as such
 307 parties remain in full compliance.
 308
 309 <LI>You are not required to accept this License, since you have not
 310 signed it.  However, nothing else grants you permission to modify or
 311 distribute the Program or its derivative works.  These actions are
 312 prohibited by law if you do not accept this License.  Therefore, by
 313 modifying or distributing the Program (or any work based on the
 314 Program), you indicate your acceptance of this License to do so, and
 315 all its terms and conditions for copying, distributing or modifying
 316 the Program or works based on it.
 317
 318 <LI>Each time you redistribute the Program (or any work based on the
 319 Program), the recipient automatically receives a license from the
 320 original licensor to copy, distribute or modify the Program subject to
 321 these terms and conditions.  You may not impose any further
 322 restrictions on the recipients' exercise of the rights granted herein.
 323 You are not responsible for enforcing compliance by third parties to
 324 this License.
 325
 326 <LI>If, as a consequence of a court judgment or allegation of patent
 327 infringement or for any other reason (not limited to patent issues),
 328 conditions are imposed on you (whether by court order, agreement or
 329 otherwise) that contradict the conditions of this License, they do not
 330 excuse you from the conditions of this License.  If you cannot
 331 distribute so as to satisfy simultaneously your obligations under this
 332 License and any other pertinent obligations, then as a consequence you
 333 may not distribute the Program at all.  For example, if a patent
 334 license would not permit royalty-free redistribution of the Program by
 335 all those who receive copies directly or indirectly through you, then
 336 the only way you could satisfy both it and this License would be to
 337 refrain entirely from distribution of the Program.
 338
 339 <P>If any portion of this section is held invalid or unenforceable under
 340 any particular circumstance, the balance of the section is intended to
 341 apply and the section as a whole is intended to apply in other
 342 circumstances.
 343
 344 <P>It is not the purpose of this section to induce you to infringe any
 345 patents or other property right claims or to contest validity of any
 346 such claims; this section has the sole purpose of protecting the
 347 integrity of the free software distribution system, which is
 348 implemented by public license practices.  Many people have made
 349 generous contributions to the wide range of software distributed
 350 through that system in reliance on consistent application of that
 351 system; it is up to the author/donor to decide if he or she is willing
 352 to distribute software through any other system and a licensee cannot
 353 impose that choice.
 354
 355 <P>This section is intended to make thoroughly clear what is believed to
 356 be a consequence of the rest of this License.
 357
 358 <LI>If the distribution and/or use of the Program is restricted in
 359 certain countries either by patents or by copyrighted interfaces, the
 360 original copyright holder who places the Program under this License
 361 may add an explicit geographical distribution limitation excluding
 362 those countries, so that distribution is permitted only in or among
 363 countries not thus excluded.  In such case, this License incorporates
 364 the limitation as if written in the body of this License.
 365
 366 <LI>The Free Software Foundation may publish revised and/or new versions
 367 of the General Public License from time to time.  Such new versions will
 368 be similar in spirit to the present version, but may differ in detail to
 369 address new problems or concerns.
 370
 371 <P>Each version is given a distinguishing version number.  If the Program
 372 specifies a version number of this License which applies to it and "any
 373 later version", you have the option of following the terms and conditions
 374 either of that version or of any later version published by the Free
 375 Software Foundation.  If the Program does not specify a version number of
 376 this License, you may choose any version ever published by the Free Software
 377 Foundation.
 378
 379 <LI>If you wish to incorporate parts of the Program into other free
 380 programs whose distribution conditions are different, write to the author
 381 to ask for permission.  For software which is copyrighted by the Free
 382 Software Foundation, write to the Free Software Foundation; we sometimes
 383 make exceptions for this.  Our decision will be guided by the two goals
 384 of preserving the free status of all derivatives of our free software and
 385 of promoting the sharing and reuse of software generally.
 386
 387 </OL>
 388
 389 <H4>NO WARRANTY</H4>
 390
 391 <OL START="11">
 392
 393 <LI>BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
 394 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
 395 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
 396 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
 397 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
 398 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
 399 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
 400 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
 401 REPAIR OR CORRECTION.
 402
 403 <LI>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 404 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
 405 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
 406 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
 407 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
 408 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY

 421
 422 <PRE>
 423 Copyright (C) 1991 Free Software Foundation, Inc.
 424 59 Temple Place - Suite 330, Boston, MA  02111-1307, USA
 425 Everyone is permitted to copy and distribute verbatim copies
 426 of this license document, but changing it is not allowed.
 427
 428 [This is the first released version of the library GPL.  It is
 429  numbered 2 because it goes with version 2 of the ordinary GPL.]
 430 </PRE>
 431
 432 <H4>Preamble</H4>
 433
 434 <P>The licenses for most software are designed to take away your
 435 freedom to share and change it.  By contrast, the GNU General Public
 436 Licenses are intended to guarantee your freedom to share and change
 437 free software--to make sure the software is free for all its users.
 438
 439 <P>This license, the Library General Public License, applies to some
 440 specially designated Free Software Foundation software, and to any
 441 other libraries whose authors decide to use it.  You can use it for
 442 your libraries, too.
 443
 444 <P>When we speak of free software, we are referring to freedom, not
 445 price.  Our General Public Licenses are designed to make sure that you
 446 have the freedom to distribute copies of free software (and charge for
 447 this service if you wish), that you receive source code or can get it
 448 if you want it, that you can change the software or use pieces of it
 449 in new free programs; and that you know you can do these things.
 450
 451 <P>To protect your rights, we need to make restrictions that forbid
 452 anyone to deny you these rights or to ask you to surrender the rights.
 453 These restrictions translate to certain responsibilities for you if
 454 you distribute copies of the library, or if you modify it.
 455
 456 <P>For example, if you distribute copies of the library, whether gratis
 457 or for a fee, you must give the recipients all the rights that we gave
 458 you.  You must make sure that they, too, receive or can get the source
 459 code.  If you link a program with the library, you must provide
 460 complete object files to the recipients so that they can relink them
 461 with the library, after making changes to the library and recompiling
 462 it.  And you must show them these terms so they know their rights.
 463
 464 <P>Our method of protecting your rights has two steps: (1) copyright
 465 the library, and (2) offer you this license which gives you legal
 466 permission to copy, distribute and/or modify the library.
 467
 468 <P>Also, for each distributor's protection, we want to make certain
 469 that everyone understands that there is no warranty for this free
 470 library.  If the library is modified by someone else and passed on, we
 471 want its recipients to know that what they have is not the original
 472 version, so that any problems introduced by others will not reflect on
 473 the original authors' reputations.
 474
 475 <P>Finally, any free program is threatened constantly by software
 476 patents.  We wish to avoid the danger that companies distributing free
 477 software will individually obtain patent licenses, thus in effect
 478 transforming the program into proprietary software.  To prevent this,
 479 we have made it clear that any patent must be licensed for everyone's
 480 free use or not licensed at all.
 481
 482 <P>Most GNU software, including some libraries, is covered by the ordinary
 483 GNU General Public License, which was designed for utility programs.  This
 484 license, the GNU Library General Public License, applies to certain
 485 designated libraries.  This license is quite different from the ordinary
 486 one; be sure to read it in full, and don't assume that anything in it is
 487 the same as in the ordinary license.
 488
 489 <P>The reason we have a separate public license for some libraries is that
 490 they blur the distinction we usually make between modifying or adding to a
 491 program and simply using it.  Linking a program with a library, without
 492 changing the library, is in some sense simply using the library, and is
 493 analogous to running a utility program or application program.  However, in
 494 a textual and legal sense, the linked executable is a combined work, a
 495 derivative of the original library, and the ordinary General Public License
 496 treats it as such.

 498 <P>Because of this blurred distinction, using the ordinary General
 499 Public License for libraries did not effectively promote software
 500 sharing, because most developers did not use the libraries.  We
 501 concluded that weaker conditions might promote sharing better.
 502
 503 <P>However, unrestricted linking of non-free programs would deprive the
 504 users of those programs of all benefit from the free status of the
 505 libraries themselves.  This Library General Public License is intended to
 506 permit developers of non-free programs to use free libraries, while
 507 preserving your freedom as a user of such programs to change the free
 508 libraries that are incorporated in them.  (We have not seen how to achieve
 509 this as regards changes in header files, but we have achieved it as regards
 510 changes in the actual functions of the Library.)  The hope is that this
 511 will lead to faster development of free libraries.
 512
 513 <P>The precise terms and conditions for copying, distribution and
 514 modification follow.  Pay close attention to the difference between a
 515 "work based on the library" and a "work that uses the library".  The
 516 former contains code derived from the library, while the latter only
 517 works together with the library.
 518
 519 <P>Note that it is possible for a library to be covered by the ordinary
 520 General Public License rather than by this special one.
 521
 522 <H4>TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</H4>
 523
 524 <P><STRONG>0.</STRONG>
 525 This License Agreement applies to any software library which
 526 contains a notice placed by the copyright holder or other authorized
 527 party saying it may be distributed under the terms of this Library
 528 General Public License (also called "this License").  Each licensee is
 529 addressed as "you".
 530
 531 <P>A "library" means a collection of software functions and/or data
 532 prepared so as to be conveniently linked with application programs
 533 (which use some of those functions and data) to form executables.
 534
 535 <P>The "Library", below, refers to any such software library or work
 536 which has been distributed under these terms.  A "work based on the
 537 Library" means either the Library or any derivative work under
 538 copyright law: that is to say, a work containing the Library or a
 539 portion of it, either verbatim or with modifications and/or translated
 540 straightforwardly into another language.  (Hereinafter, translation is
 541 included without limitation in the term "modification".)
 542
 543 <P>"Source code" for a work means the preferred form of the work for
 544 making modifications to it.  For a library, complete source code means
 545 all the source code for all modules it contains, plus any associated
 546 interface definition files, plus the scripts used to control compilation
 547 and installation of the library.
 548
 549 <P>Activities other than copying, distribution and modification are not
 550 covered by this License; they are outside its scope.  The act of
 551 running a program using the Library is not restricted, and output from
 552 such a program is covered only if its contents constitute a work based
 553 on the Library (independent of the use of the Library in a tool for
 554 writing it).  Whether that is true depends on what the Library does
 555 and what the program that uses the Library does.
 556
 557 <P><STRONG>1.</STRONG>
 558 You may copy and distribute verbatim copies of the Library's
 559 complete source code as you receive it, in any medium, provided that
 560 you conspicuously and appropriately publish on each copy an
 561 appropriate copyright notice and disclaimer of warranty; keep intact
 562 all the notices that refer to this License and to the absence of any
 563 warranty; and distribute a copy of this License along with the
 564 Library.
 565
 566 <P>You may charge a fee for the physical act of transferring a copy,
 567 and you may at your option offer warranty protection in exchange for a
 568 fee.
 569
 570 <P><STRONG>2.</STRONG>
 571 You may modify your copy or copies of the Library or any portion
 572 of it, thus forming a work based on the Library, and copy and
 573 distribute such modifications or work under the terms of Section 1
 574 above, provided that you also meet all of these conditions:
 575
 576 <OL TYPE="a">
 577
 578         <LI>The modified work must itself be a software library.
 579
 580         <P>
 581         <LI>You must cause the files modified to carry prominent notices
 582         stating that you changed the files and the date of any change.
 583
 584         <P>
 585         <LI>You must cause the whole of the work to be licensed at no
 586         charge to all third parties under the terms of this License.
 587
 588         <P>
 589         <LI>If a facility in the modified Library refers to a function or a
 590         table of data to be supplied by an application program that uses
 591         the facility, other than as an argument passed when the facility
 592         is invoked, then you must make a good faith effort to ensure that,
 593         in the event an application does not supply such function or
 594         table, the facility still operates, and performs whatever part of
 595         its purpose remains meaningful.
 596
 597         <P>(For example, a function in a library to compute square roots has
 598         a purpose that is entirely well-defined independent of the
 599         application.  Therefore, Subsection 2d requires that any
 600         application-supplied function or table used by this function must
 601         be optional: if the application does not supply it, the square
 602         root function must still compute square roots.)
 603
 604 </OL>
 605
 606 <P>These requirements apply to the modified work as a whole.  If
 607 identifiable sections of that work are not derived from the Library,
 608 and can be reasonably considered independent and separate works in
 609 themselves, then this License, and its terms, do not apply to those
 610 sections when you distribute them as separate works.  But when you
 611 distribute the same sections as part of a whole which is a work based
 612 on the Library, the distribution of the whole must be on the terms of
 613 this License, whose permissions for other licensees extend to the
 614 entire whole, and thus to each and every part regardless of who wrote
 615 it.
 616
 617 <P>Thus, it is not the intent of this section to claim rights or contest
 618 your rights to work written entirely by you; rather, the intent is to
 619 exercise the right to control the distribution of derivative or
 620 collective works based on the Library.
 621
 622 <P>In addition, mere aggregation of another work not based on the Library
 623 with the Library (or with a work based on the Library) on a volume of
 624 a storage or distribution medium does not bring the other work under
 625 the scope of this License.
 626
 627 <P><STRONG>3.</STRONG>
 628 You may opt to apply the terms of the ordinary GNU General Public
 629 License instead of this License to a given copy of the Library.  To do
 630 this, you must alter all the notices that refer to this License, so
 631 that they refer to the ordinary GNU General Public License, version 2,
 632 instead of to this License.  (If a newer version than version 2 of the
 633 ordinary GNU General Public License has appeared, then you can specify
 634 that version instead if you wish.)  Do not make any other change in
 635 these notices.
 636
 637 <P>Once this change is made in a given copy, it is irreversible for
 638 that copy, so the ordinary GNU General Public License applies to all
 639 subsequent copies and derivative works made from that copy.
 640
 641 <P>This option is useful when you wish to copy part of the code of
 642 the Library into a program that is not a library.
 643
 644 <P><STRONG>4.</STRONG>
 645 You may copy and distribute the Library (or a portion or
 646 derivative of it, under Section 2) in object code or executable form
 647 under the terms of Sections 1 and 2 above provided that you accompany
 648 it with the complete corresponding machine-readable source code, which
 649 must be distributed under the terms of Sections 1 and 2 above on a
 650 medium customarily used for software interchange.
 651
 652 <P>If distribution of object code is made by offering access to copy
 653 from a designated place, then offering equivalent access to copy the
 654 source code from the same place satisfies the requirement to
 655 distribute the source code, even though third parties are not
 656 compelled to copy the source along with the object code.
 657
 658 <P><STRONG>5.</STRONG>
 659 A program that contains no derivative of any portion of the
 660 Library, but is designed to work with the Library by being compiled or
 661 linked with it, is called a "work that uses the Library".  Such a
 662 work, in isolation, is not a derivative work of the Library, and
 663 therefore falls outside the scope of this License.
 664
 665 <P>However, linking a "work that uses the Library" with the Library
 666 creates an executable that is a derivative of the Library (because it
 667 contains portions of the Library), rather than a "work that uses the
 668 library".  The executable is therefore covered by this License.
 669 Section 6 states terms for distribution of such executables.
 670
 671 <P>When a "work that uses the Library" uses material from a header file
 672 that is part of the Library, the object code for the work may be a
 673 derivative work of the Library even though the source code is not.
 674 Whether this is true is especially significant if the work can be
 675 linked without the Library, or if the work is itself a library.  The
 676 threshold for this to be true is not precisely defined by law.
 677
 678 <P>If such an object file uses only numerical parameters, data
 679 structure layouts and accessors, and small macros and small inline
 680 functions (ten lines or less in length), then the use of the object
 681 file is unrestricted, regardless of whether it is legally a derivative
 682 work.  (Executables containing this object code plus portions of the
 683 Library will still fall under Section 6.)
 684
 685 <P>Otherwise, if the work is a derivative of the Library, you may
 686 distribute the object code for the work under the terms of Section 6.
 687 Any executables containing that work also fall under Section 6,
 688 whether or not they are linked directly with the Library itself.
 689
 690 <P><STRONG>6.</STRONG>
 691 As an exception to the Sections above, you may also compile or
 692 link a "work that uses the Library" with the Library to produce a
 693 work containing portions of the Library, and distribute that work
 694 under terms of your choice, provided that the terms permit
 695 modification of the work for the customer's own use and reverse
 696 engineering for debugging such modifications.
 697
 698 <P>You must give prominent notice with each copy of the work that the
 699 Library is used in it and that the Library and its use are covered by
 700 this License.  You must supply a copy of this License.  If the work
 701 during execution displays copyright notices, you must include the
 702 copyright notice for the Library among them, as well as a reference
 703 directing the user to the copy of this License.  Also, you must do one
 704 of these things:
 705
 706 <OL TYPE="a">
 707
 708         <LI>Accompany the work with the complete corresponding
 709         machine-readable source code for the Library including whatever
 710         changes were used in the work (which must be distributed under
 711         Sections 1 and 2 above); and, if the work is an executable linked
 712         with the Library, with the complete machine-readable "work that
 713         uses the Library", as object code and/or source code, so that the
 714         user can modify the Library and then relink to produce a modified
 715         executable containing the modified Library.  (It is understood
 716         that the user who changes the contents of definitions files in the
 717         Library will not necessarily be able to recompile the application
 718         to use the modified definitions.)
 719
 720         <P>
 721         <LI>Accompany the work with a written offer, valid for at
 722         least three years, to give the same user the materials
 723         specified in Subsection 6a, above, for a charge no more
 724         than the cost of performing this distribution.
 725
 726         <P>
 727         <LI>If distribution of the work is made by offering access to copy
 728         from a designated place, offer equivalent access to copy the above

 735 </OL>
 736
 737 <P>For an executable, the required form of the "work that uses the
 738 Library" must include any data and utility programs needed for
 739 reproducing the executable from it.  However, as a special exception,
 740 the source code distributed need not include anything that is normally
 741 distributed (in either source or binary form) with the major
 742 components (compiler, kernel, and so on) of the operating system on
 743 which the executable runs, unless that component itself accompanies
 744 the executable.
 745
 746 <P>It may happen that this requirement contradicts the license
 747 restrictions of other proprietary libraries that do not normally
 748 accompany the operating system.  Such a contradiction means you cannot
 749 use both them and the Library together in an executable that you
 750 distribute.

 753 You may place library facilities that are a work based on the
 754 Library side-by-side in a single library together with other library
 755 facilities not covered by this License, and distribute such a combined
 756 library, provided that the separate distribution of the work based on
 757 the Library and of the other library facilities is otherwise
 758 permitted, and provided that you do these two things:
 759

 775 You may not copy, modify, sublicense, link with, or distribute
 776 the Library except as expressly provided under this License.  Any
 777 attempt otherwise to copy, modify, sublicense, link with, or
 778 distribute the Library is void, and will automatically terminate your
 779 rights under this License.  However, parties who have received copies,
 780 or rights, from you under this License will not have their licenses
 781 terminated so long as such parties remain in full compliance.
 782
 783 <P><STRONG>9.</STRONG>
 784 You are not required to accept this License, since you have not
 785 signed it.  However, nothing else grants you permission to modify or
 786 distribute the Library or its derivative works.  These actions are
 787 prohibited by law if you do not accept this License.  Therefore, by
 788 modifying or distributing the Library (or any work based on the
 789 Library), you indicate your acceptance of this License to do so, and
 790 all its terms and conditions for copying, distributing or modifying
 791 the Library or works based on it.
 792
 793 <P><STRONG>10.</STRONG>
 794 Each time you redistribute the Library (or any work based on the
 795 Library), the recipient automatically receives a license from the
 796 original licensor to copy, distribute, link with or modify the Library
 797 subject to these terms and conditions.  You may not impose any further
 798 restrictions on the recipients' exercise of the rights granted herein.
 799 You are not responsible for enforcing compliance by third parties to
 800 this License.

 803 If, as a consequence of a court judgment or allegation of patent
 804 infringement or for any other reason (not limited to patent issues),
 805 conditions are imposed on you (whether by court order, agreement or
 806 otherwise) that contradict the conditions of this License, they do not
 807 excuse you from the conditions of this License.  If you cannot
 808 distribute so as to satisfy simultaneously your obligations under this
 809 License and any other pertinent obligations, then as a consequence you
 810 may not distribute the Library at all.  For example, if a patent
 811 license would not permit royalty-free redistribution of the Library by
 812 all those who receive copies directly or indirectly through you, then
 813 the only way you could satisfy both it and this License would be to
 814 refrain entirely from distribution of the Library.

 819
 820 <P>It is not the purpose of this section to induce you to infringe any
 821 patents or other property right claims or to contest validity of any
 822 such claims; this section has the sole purpose of protecting the
 823 integrity of the free software distribution system which is
 824 implemented by public license practices.  Many people have made
 825 generous contributions to the wide range of software distributed
 826 through that system in reliance on consistent application of that
 827 system; it is up to the author/donor to decide if he or she is willing
 828 to distribute software through any other system and a licensee cannot
 829 impose that choice.

 832 be a consequence of the rest of this License.

 834 <P><STRONG>12.</STRONG>
 835 If the distribution and/or use of the Library is restricted in
 836 certain countries either by patents or by copyrighted interfaces, the
 837 original copyright holder who places the Library under this License may add
 838 an explicit geographical distribution limitation excluding those countries,
 839 so that distribution is permitted only in or among countries not thus
 840 excluded.  In such case, this License incorporates the limitation as if
 841 written in the body of this License.

 844 The Free Software Foundation may publish revised and/or new
 845 versions of the Library General Public License from time to time.
 846 Such new versions will be similar in spirit to the present version,
 847 but may differ in detail to address new problems or concerns.
 848
 849 <P>Each version is given a distinguishing version number.  If the Library
 850 specifies a version number of this License which applies to it and
 851 "any later version", you have the option of following the terms and
 852 conditions either of that version or of any later version published by
 853 the Free Software Foundation.  If the Library does not specify a
 854 license version number, you may choose any version ever published by
 855 the Free Software Foundation.

 858 If you wish to incorporate parts of the Library into other free

 861 copyrighted by the Free Software Foundation, write to the Free
 862 Software Foundation; we sometimes make exceptions for this.  Our

 864 of all derivatives of our free software and of promoting the sharing
 865 and reuse of software generally.
