   6  Everyone is permitted to copy and distribute verbatim copies
 		
   7  of this license document, but changing it is not allowed.
 		
		
   9 [This is the first released version of the Lesser GPL.  It also counts
 		
  10  as the successor of the GNU Library Public License, version 2, hence
 		
  11  the version number 2.1.]
 		
		
		
		
  15   The licenses for most software are designed to take away your
 		
  16 freedom to share and change it.  By contrast, the GNU General Public
 		
  17 Licenses are intended to guarantee your freedom to share and change
 		
  18 free software--to make sure the software is free for all its users.
 		
		
  20   This license, the Lesser General Public License, applies to some
 		
  21 specially designated software packages--typically libraries--of the
 		
  22 Free Software Foundation and other authors who decide to use it.  You
 		
  23 can use it too, but we suggest you first think carefully about whether
 		
  24 this license or the ordinary General Public License is the better
 		
  25 strategy to use in any particular case, based on the explanations
 		
		
		
  28   When we speak of free software, we are referring to freedom of use,
 		
  29 not price.  Our General Public Licenses are designed to make sure that
 		
  30 you have the freedom to distribute copies of free software (and charge
 		
  31 for this service if you wish); that you receive source code or can get
 		
  32 it if you want it; that you can change the software and use pieces of
 		
  33 it in new free programs; and that you are informed that you can do
 		
		
		
  36   To protect your rights, we need to make restrictions that forbid
 		
  37 distributors to deny you these rights or to ask you to surrender these
 		
  38 rights.  These restrictions translate to certain responsibilities for
 		
  39 you if you distribute copies of the library or if you modify it.
 		
		
  41   For example, if you distribute copies of the library, whether gratis
 		
  42 or for a fee, you must give the recipients all the rights that we gave
 		
  43 you.  You must make sure that they, too, receive or can get the source
 		
  44 code.  If you link other code with the library, you must provide
 		
  45 complete object files to the recipients, so that they can relink them
 		
  46 with the library after making changes to the library and recompiling
 		
  47 it.  And you must show them these terms so they know their rights.
 		
		
  49   We protect your rights with a two-step method: (1) we copyright the
 		
  50 library, and (2) we offer you this license, which gives you legal
 		
  51 permission to copy, distribute and/or modify the library.
 		
		
  53   To protect each distributor, we want to make it very clear that
 		
  54 there is no warranty for the free library.  Also, if the library is
 		
  55 modified by someone else and passed on, the recipients should know
 		
  56 that what they have is not the original version, so that the original
 		
  57 author's reputation will not be affected by problems that might be
 		
		
		
  60   Finally, software patents pose a constant threat to the existence of
 		
  61 any free program.  We wish to make sure that a company cannot
 		
  62 effectively restrict the users of a free program by obtaining a
 		
  63 restrictive license from a patent holder.  Therefore, we insist that
 		
  64 any patent license obtained for a version of the library must be
 		
  65 consistent with the full freedom of use specified in this license.
 		
		
  67   Most GNU software, including some libraries, is covered by the
 		
  68 ordinary GNU General Public License.  This license, the GNU Lesser
 		
  69 General Public License, applies to certain designated libraries, and
 		
  70 is quite different from the ordinary General Public License.  We use
 		
  71 this license for certain libraries in order to permit linking those
 		
  72 libraries into non-free programs.
 		
		
  74   When a program is linked with a library, whether statically or using
 		
  75 a shared library, the combination of the two is legally speaking a
 		
  76 combined work, a derivative of the original library.  The ordinary
 		
  77 General Public License therefore permits such linking only if the
 		
  78 entire combination fits its criteria of freedom.  The Lesser General
 		
  79 Public License permits more lax criteria for linking other code with
 		
		
		
  82   We call this license the "Lesser" General Public License because it
 		
  83 does Less to protect the user's freedom than the ordinary General
 		
  84 Public License.  It also provides other free software developers Less
 		
  85 of an advantage over competing non-free programs.  These disadvantages
 		
  86 are the reason we use the ordinary General Public License for many
 		
  87 libraries.  However, the Lesser license provides advantages in certain
 		
  88 special circumstances.
 		
		
  90   For example, on rare occasions, there may be a special need to
 		
  91 encourage the widest possible use of a certain library, so that it
 		
  92 becomes a de-facto standard.  To achieve this, non-free programs must
 		
  93 be allowed to use the library.  A more frequent case is that a free
 		
  94 library does the same job as widely used non-free libraries.  In this
 		
  95 case, there is little to gain by limiting the free library to free
 		
  96 software only, so we use the Lesser General Public License.
 		
		
  98   In other cases, permission to use a particular library in non-free
 		
  99 programs enables a greater number of people to use a large body of
 		
 100 free software.  For example, permission to use the GNU C Library in
 		
 101 non-free programs enables many more people to use the whole GNU
 		
 102 operating system, as well as its variant, the GNU/Linux operating
 		
		
		
 105   Although the Lesser General Public License is Less protective of the
 		
 106 users' freedom, it does ensure that the user of a program that is
 		
 107 linked with the Library has the freedom and the wherewithal to run
 		
 108 that program using a modified version of the Library.
 		
		
 110   The precise terms and conditions for copying, distribution and
 		
 111 modification follow.  Pay close attention to the difference between a
 		
 112 "work based on the library" and a "work that uses the library".  The
 		
 113 former contains code derived from the library, whereas the latter must
 		
 114 be combined with the library in order to run.
 		
		
		
 117                   GNU LESSER GENERAL PUBLIC LICENSE
 		
 118    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 		
		
 120   0. This License Agreement applies to any software library or other
 		
 121 program which contains a notice placed by the copyright holder or
 		
 122 other authorized party saying it may be distributed under the terms of
 		
 123 this Lesser General Public License (also called "this License").
 		
 124 Each licensee is addressed as "you".
 		
		
 126   A "library" means a collection of software functions and/or data
 		
 127 prepared so as to be conveniently linked with application programs
 		
 128 (which use some of those functions and data) to form executables.
 		
		
 130   The "Library", below, refers to any such software library or work
 		
 131 which has been distributed under these terms.  A "work based on the
 		
 132 Library" means either the Library or any derivative work under
 		
 133 copyright law: that is to say, a work containing the Library or a
 		
 134 portion of it, either verbatim or with modifications and/or translated
 		
 135 straightforwardly into another language.  (Hereinafter, translation is
 		
 136 included without limitation in the term "modification".)
 		
		
 138   "Source code" for a work means the preferred form of the work for
 		
 139 making modifications to it.  For a library, complete source code means
 		
 140 all the source code for all modules it contains, plus any associated
 		
 141 interface definition files, plus the scripts used to control
 		
 142 compilation and installation of the library.
 		
		
 144   Activities other than copying, distribution and modification are not
 		
 145 covered by this License; they are outside its scope.  The act of
 		
 146 running a program using the Library is not restricted, and output from
 		
 147 such a program is covered only if its contents constitute a work based
 		
 148 on the Library (independent of the use of the Library in a tool for
 		
 149 writing it).  Whether that is true depends on what the Library does
 		
 150 and what the program that uses the Library does.
 		
		
 152   1. You may copy and distribute verbatim copies of the Library's
 		
 153 complete source code as you receive it, in any medium, provided that
 		
 154 you conspicuously and appropriately publish on each copy an
 		
 155 appropriate copyright notice and disclaimer of warranty; keep intact
 		
 156 all the notices that refer to this License and to the absence of any
 		
 157 warranty; and distribute a copy of this License along with the
 		
		
		
 160   You may charge a fee for the physical act of transferring a copy,
 		
 161 and you may at your option offer warranty protection in exchange for a
 		
		
		
 164   2. You may modify your copy or copies of the Library or any portion
 		
 165 of it, thus forming a work based on the Library, and copy and
 		
 166 distribute such modifications or work under the terms of Section 1
 		
 167 above, provided that you also meet all of these conditions:
 		
		
 169     a) The modified work must itself be a software library.
 		
		
 171     b) You must cause the files modified to carry prominent notices
 		
 172     stating that you changed the files and the date of any change.
 		
		
 174     c) You must cause the whole of the work to be licensed at no
 		
 175     charge to all third parties under the terms of this License.
 		
		
 177     d) If a facility in the modified Library refers to a function or a
 		
 178     table of data to be supplied by an application program that uses
 		
 179     the facility, other than as an argument passed when the facility
 		
 180     is invoked, then you must make a good faith effort to ensure that,
 		
 181     in the event an application does not supply such function or
 		
 182     table, the facility still operates, and performs whatever part of
 		
 183     its purpose remains meaningful.
 		
		
 185     (For example, a function in a library to compute square roots has
 		
 186     a purpose that is entirely well-defined independent of the
 		
 187     application.  Therefore, Subsection 2d requires that any
 		
 188     application-supplied function or table used by this function must
 		
 189     be optional: if the application does not supply it, the square
 		
 190     root function must still compute square roots.)
 		
		
 192 These requirements apply to the modified work as a whole.  If
 		
 193 identifiable sections of that work are not derived from the Library,
 		
 194 and can be reasonably considered independent and separate works in
 		
 195 themselves, then this License, and its terms, do not apply to those
 		
 196 sections when you distribute them as separate works.  But when you
 		
 197 distribute the same sections as part of a whole which is a work based
 		
 198 on the Library, the distribution of the whole must be on the terms of
 		
 199 this License, whose permissions for other licensees extend to the
 		
 200 entire whole, and thus to each and every part regardless of who wrote
 		
		
		
 203 Thus, it is not the intent of this section to claim rights or contest
 		
 204 your rights to work written entirely by you; rather, the intent is to
 		
 205 exercise the right to control the distribution of derivative or
 		
 206 collective works based on the Library.
 		
		
 208 In addition, mere aggregation of another work not based on the Library
 		
 209 with the Library (or with a work based on the Library) on a volume of
 		
 210 a storage or distribution medium does not bring the other work under
 		
 211 the scope of this License.
 		
		
 213   3. You may opt to apply the terms of the ordinary GNU General Public
 		
 214 License instead of this License to a given copy of the Library.  To do
 		
 215 this, you must alter all the notices that refer to this License, so
 		
 216 that they refer to the ordinary GNU General Public License, version 2,
 		
 217 instead of to this License.  (If a newer version than version 2 of the
 		
 218 ordinary GNU General Public License has appeared, then you can specify
 		
 219 that version instead if you wish.)  Do not make any other change in
 		
		
		
 222   Once this change is made in a given copy, it is irreversible for
 		
 223 that copy, so the ordinary GNU General Public License applies to all
 		
 224 subsequent copies and derivative works made from that copy.
 		
		
 226   This option is useful when you wish to copy part of the code of
 		
 227 the Library into a program that is not a library.
 		
		
 229   4. You may copy and distribute the Library (or a portion or
 		
 230 derivative of it, under Section 2) in object code or executable form
 		
 231 under the terms of Sections 1 and 2 above provided that you accompany
 		
 232 it with the complete corresponding machine-readable source code, which
 		
 233 must be distributed under the terms of Sections 1 and 2 above on a
 		
 234 medium customarily used for software interchange.
 		
		
 236   If distribution of object code is made by offering access to copy
 		
 237 from a designated place, then offering equivalent access to copy the
 		
 238 source code from the same place satisfies the requirement to
 		
 239 distribute the source code, even though third parties are not
 		
 240 compelled to copy the source along with the object code.
 		
		
 242   5. A program that contains no derivative of any portion of the
 		
 243 Library, but is designed to work with the Library by being compiled or
 		
 244 linked with it, is called a "work that uses the Library".  Such a
 		
 245 work, in isolation, is not a derivative work of the Library, and
 		
 246 therefore falls outside the scope of this License.
 		
		
 248   However, linking a "work that uses the Library" with the Library
 		
 249 creates an executable that is a derivative of the Library (because it
 		
 250 contains portions of the Library), rather than a "work that uses the
 		
 251 library".  The executable is therefore covered by this License.
 		
 252 Section 6 states terms for distribution of such executables.
 		
		
 254   When a "work that uses the Library" uses material from a header file
 		
 255 that is part of the Library, the object code for the work may be a
 		
 256 derivative work of the Library even though the source code is not.
 		
 257 Whether this is true is especially significant if the work can be
 		
 258 linked without the Library, or if the work is itself a library.  The
 		
 259 threshold for this to be true is not precisely defined by law.
 		
		
 261   If such an object file uses only numerical parameters, data
 		
 262 structure layouts and accessors, and small macros and small inline
 		
 263 functions (ten lines or less in length), then the use of the object
 		
 264 file is unrestricted, regardless of whether it is legally a derivative
 		
 265 work.  (Executables containing this object code plus portions of the
 		
 266 Library will still fall under Section 6.)
 		
		
 268   Otherwise, if the work is a derivative of the Library, you may
 		
 269 distribute the object code for the work under the terms of Section 6.
 		
 270 Any executables containing that work also fall under Section 6,
 		
 271 whether or not they are linked directly with the Library itself.
 		
		
 273   6. As an exception to the Sections above, you may also combine or
 		
 274 link a "work that uses the Library" with the Library to produce a
 		
 275 work containing portions of the Library, and distribute that work
 		
 276 under terms of your choice, provided that the terms permit
 		
 277 modification of the work for the customer's own use and reverse
 		
 278 engineering for debugging such modifications.
 		
		
 280   You must give prominent notice with each copy of the work that the
 		
 281 Library is used in it and that the Library and its use are covered by
 		
 282 this License.  You must supply a copy of this License.  If the work
 		
 283 during execution displays copyright notices, you must include the
 		
 284 copyright notice for the Library among them, as well as a reference
 		
 285 directing the user to the copy of this License.  Also, you must do one
 		
		
		
 288     a) Accompany the work with the complete corresponding
 		
 289     machine-readable source code for the Library including whatever
 		
 290     changes were used in the work (which must be distributed under
 		
 291     Sections 1 and 2 above); and, if the work is an executable linked
 		
 292     with the Library, with the complete machine-readable "work that
 		
 293     uses the Library", as object code and/or source code, so that the
 		
 294     user can modify the Library and then relink to produce a modified
 		
 295     executable containing the modified Library.  (It is understood
 		
 296     that the user who changes the contents of definitions files in the
 		
 297     Library will not necessarily be able to recompile the application
 		
 298     to use the modified definitions.)
 		
		
 300     b) Use a suitable shared library mechanism for linking with the
 		
 301     Library.  A suitable mechanism is one that (1) uses at run time a
 		
 302     copy of the library already present on the user's computer system,
 		
 303     rather than copying library functions into the executable, and (2)
 		
 304     will operate properly with a modified version of the library, if
 		
 305     the user installs one, as long as the modified version is
 		
 306     interface-compatible with the version that the work was made with.
 		
		
 308     c) Accompany the work with a written offer, valid for at least
 		
 309     three years, to give the same user the materials specified in
 		
 310     Subsection 6a, above, for a charge no more than the cost of
 		
 311     performing this distribution.
 		
		
 313     d) If distribution of the work is made by offering access to copy
 		
 314     from a designated place, offer equivalent access to copy the above
 		
 315     specified materials from the same place.
 		
		
 317     e) Verify that the user has already received a copy of these
 		
 318     materials or that you have already sent this user a copy.
 		
		
 320   For an executable, the required form of the "work that uses the
 		
 321 Library" must include any data and utility programs needed for
 		
 322 reproducing the executable from it.  However, as a special exception,
 		
 323 the materials to be distributed need not include anything that is
 		
 324 normally distributed (in either source or binary form) with the major
 		
 325 components (compiler, kernel, and so on) of the operating system on
 		
 326 which the executable runs, unless that component itself accompanies
 		
		
		
 329   It may happen that this requirement contradicts the license
 		
 330 restrictions of other proprietary libraries that do not normally
 		
 331 accompany the operating system.  Such a contradiction means you cannot
 		
 332 use both them and the Library together in an executable that you
 		
		
		
 335   7. You may place library facilities that are a work based on the
 		
 336 Library side-by-side in a single library together with other library
 		
 337 facilities not covered by this License, and distribute such a combined
 		
 338 library, provided that the separate distribution of the work based on
 		
 339 the Library and of the other library facilities is otherwise
 		
 340 permitted, and provided that you do these two things:
 		
		
 342     a) Accompany the combined library with a copy of the same work
 		
 343     based on the Library, uncombined with any other library
 		
 344     facilities.  This must be distributed under the terms of the
 		
		
		
 347     b) Give prominent notice with the combined library of the fact
 		
 348     that part of it is a work based on the Library, and explaining
 		
 349     where to find the accompanying uncombined form of the same work.
 		
		
 351   8. You may not copy, modify, sublicense, link with, or distribute
 		
 352 the Library except as expressly provided under this License.  Any
 		
 353 attempt otherwise to copy, modify, sublicense, link with, or
 		
 354 distribute the Library is void, and will automatically terminate your
 		
 355 rights under this License.  However, parties who have received copies,
 		
 356 or rights, from you under this License will not have their licenses
 		
 357 terminated so long as such parties remain in full compliance.
 		
		
 359   9. You are not required to accept this License, since you have not
 		
 360 signed it.  However, nothing else grants you permission to modify or
 		
 361 distribute the Library or its derivative works.  These actions are
 		
 362 prohibited by law if you do not accept this License.  Therefore, by
 		
 363 modifying or distributing the Library (or any work based on the
 		
 364 Library), you indicate your acceptance of this License to do so, and
 		
 365 all its terms and conditions for copying, distributing or modifying
 		
 366 the Library or works based on it.
 		
		
 368   10. Each time you redistribute the Library (or any work based on the
 		
 369 Library), the recipient automatically receives a license from the
 		
 370 original licensor to copy, distribute, link with or modify the Library
 		
 371 subject to these terms and conditions.  You may not impose any further
 		
 372 restrictions on the recipients' exercise of the rights granted herein.
 		
 373 You are not responsible for enforcing compliance by third parties with
 		
		
		
 376   11. If, as a consequence of a court judgment or allegation of patent
 		
 377 infringement or for any other reason (not limited to patent issues),
 		
 378 conditions are imposed on you (whether by court order, agreement or
 		
 379 otherwise) that contradict the conditions of this License, they do not
 		
 380 excuse you from the conditions of this License.  If you cannot
 		
 381 distribute so as to satisfy simultaneously your obligations under this
 		
 382 License and any other pertinent obligations, then as a consequence you
 		
 383 may not distribute the Library at all.  For example, if a patent
 		
 384 license would not permit royalty-free redistribution of the Library by
 		
 385 all those who receive copies directly or indirectly through you, then
 		
 386 the only way you could satisfy both it and this License would be to
 		
 387 refrain entirely from distribution of the Library.
 		
		
 389 If any portion of this section is held invalid or unenforceable under
 		
 390 any particular circumstance, the balance of the section is intended to
 		
 391 apply, and the section as a whole is intended to apply in other
 		
		
		
 394 It is not the purpose of this section to induce you to infringe any
 		
 395 patents or other property right claims or to contest validity of any
 		
 396 such claims; this section has the sole purpose of protecting the
 		
 397 integrity of the free software distribution system which is
 		
 398 implemented by public license practices.  Many people have made
 		
 399 generous contributions to the wide range of software distributed
 		
 400 through that system in reliance on consistent application of that
 		
 401 system; it is up to the author/donor to decide if he or she is willing
 		
 402 to distribute software through any other system and a licensee cannot
 		
		
		
 405 This section is intended to make thoroughly clear what is believed to
 		
 406 be a consequence of the rest of this License.
 		
		
 408   12. If the distribution and/or use of the Library is restricted in
 		
 409 certain countries either by patents or by copyrighted interfaces, the
 		
 410 original copyright holder who places the Library under this License
 		
 411 may add an explicit geographical distribution limitation excluding those
 		
 412 countries, so that distribution is permitted only in or among
 		
 413 countries not thus excluded.  In such case, this License incorporates
 		
 414 the limitation as if written in the body of this License.
 		
		
 416   13. The Free Software Foundation may publish revised and/or new
 		
 417 versions of the Lesser General Public License from time to time.
 		
 418 Such new versions will be similar in spirit to the present version,
 		
 419 but may differ in detail to address new problems or concerns.
 		
		
 421 Each version is given a distinguishing version number.  If the Library
 		
 422 specifies a version number of this License which applies to it and
 		
 423 "any later version", you have the option of following the terms and
 		
 424 conditions either of that version or of any later version published by
 		
 425 the Free Software Foundation.  If the Library does not specify a
 		
 426 license version number, you may choose any version ever published by
 		
 427 the Free Software Foundation.
 		
		
 429   14. If you wish to incorporate parts of the Library into other free
 		
 430 programs whose distribution conditions are incompatible with these,
 		
 431 write to the author to ask for permission.  For software which is
 		
 432 copyrighted by the Free Software Foundation, write to the Free
 		
 433 Software Foundation; we sometimes make exceptions for this.  Our
 		
 434 decision will be guided by the two goals of preserving the free status
 		
 435 of all derivatives of our free software and of promoting the sharing
 		
 436 and reuse of software generally.
 		
		
		
		
 440   15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
 		
 441 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
 		
 442 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
 		
 443 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
 		
 444 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
 		
 445 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 		
 446 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
 		
 447 LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
 		
 448 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
 		
		
 450   16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
 		
 451 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY

 453 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
 		
 454 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE

 456 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
 		
 457 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
 		
 458 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
 		
		
		
 461                      END OF TERMS AND CONDITIONS
 		
		
		
 464            How to Apply These Terms to Your New Libraries
 		
		
 466   If you develop a new library, and you want it to be of the greatest
 		
 467 possible use to the public, we recommend making it free software that
 		
 468 everyone can redistribute and change.  You can do so by permitting
 		
 469 redistribution under these terms (or, alternatively, under the terms of the
 		
 470 ordinary General Public License).
 		
		
 472   To apply these terms, attach the following notices to the library.  It is
 		
 473 safest to attach them to the start of each source file to most effectively
 		
 474 convey the exclusion of warranty; and each file should have at least the
 		
 475 "copyright" line and a pointer to where the full notice is found.
 		
		
 477     <one line to give the library's name and a brief idea of what it does.>
 		
 478     Copyright (C) <year>  <name of author>
 		
		
 480     This library is free software; you can redistribute it and/or
 		
 481     modify it under the terms of the GNU Lesser General Public
 		
 482     License as published by the Free Software Foundation; either
 		
 483     version 2.1 of the License, or (at your option) any later version.
 		
		
 485     This library is distributed in the hope that it will be useful,
 		
 486     but WITHOUT ANY WARRANTY; without even the implied warranty of
 		
 487     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
 		
 488     Lesser General Public License for more details.
 		
		
 490     You should have received a copy of the GNU Lesser General Public
 		
 491     License along with this library; if not, write to the Free Software
 		
 492     Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
 		
		
 494 Also add information on how to contact you by electronic and paper mail.
 		
		
 496 You should also get your employer (if you work as a programmer) or your
 		
 497 school, if any, to sign a "copyright disclaimer" for the library, if
 		
 498 necessary.  Here is a sample; alter the names:
 		
		
 500   Yoyodyne, Inc., hereby disclaims all copyright interest in the
 		
 501   library `Frob' (a library for tweaking knobs) written by James Random Hacker.
