     1.6 +		       Version 2, June 1991
     1.7 +
     1.8 +
     1.9 + Copyright (C) 1991 Free Software Foundation, Inc.
    1.10 +                    675 Mass Ave, Cambridge, MA 02139, USA
    1.11 + Everyone is permitted to copy and distribute verbatim copies
    1.12 + of this license document, but changing it is not allowed.
    1.13 +
    1.14 +[This is the first released version of the library GPL.  It is
    1.15 + numbered 2 because it goes with version 2 of the ordinary GPL.]
    1.16 +
    1.17 +			    Preamble
    1.18 +
    1.19 +  The licenses for most software are designed to take away your
    1.20 +freedom to share and change it.  By contrast, the GNU General Public
    1.21 +Licenses are intended to guarantee your freedom to share and change
    1.22 +free software--to make sure the software is free for all its users.
    1.23 +
    1.24 +  This license, the Library General Public License, applies to some
    1.25 +specially designated Free Software Foundation software, and to any
    1.26 +other libraries whose authors decide to use it.  You can use it for
    1.27 +your libraries, too.
    1.28 +
    1.29 +  When we speak of free software, we are referring to freedom, not
    1.30 +price.  Our General Public Licenses are designed to make sure that you
    1.31 +have the freedom to distribute copies of free software (and charge for
    1.32 +this service if you wish), that you receive source code or can get it
    1.33 +if you want it, that you can change the software or use pieces of it
    1.34 +in new free programs; and that you know you can do these things.
    1.35 +
    1.36 +  To protect your rights, we need to make restrictions that forbid
    1.37 +anyone to deny you these rights or to ask you to surrender the rights.
    1.38 +These restrictions translate to certain responsibilities for you if
    1.39 +you distribute copies of the library, or if you modify it.
    1.40 +
    1.41 +  For example, if you distribute copies of the library, whether gratis
    1.42 +or for a fee, you must give the recipients all the rights that we gave
    1.43 +you.  You must make sure that they, too, receive or can get the source
    1.44 +code.  If you link a program with the library, you must provide
    1.45 +complete object files to the recipients so that they can relink them
    1.46 +with the library, after making changes to the library and recompiling
    1.47 +it.  And you must show them these terms so they know their rights.
    1.48 +
    1.49 +  Our method of protecting your rights has two steps: (1) copyright
    1.50 +the library, and (2) offer you this license which gives you legal
    1.51 +permission to copy, distribute and/or modify the library.
    1.52 +
    1.53 +  Also, for each distributor's protection, we want to make certain
    1.54 +that everyone understands that there is no warranty for this free
    1.55 +library.  If the library is modified by someone else and passed on, we
    1.56 +want its recipients to know that what they have is not the original
    1.57 +version, so that any problems introduced by others will not reflect on
    1.58 +the original authors' reputations.
    1.59 +
    1.60 +  Finally, any free program is threatened constantly by software
    1.61 +patents.  We wish to avoid the danger that companies distributing free
    1.62 +software will individually obtain patent licenses, thus in effect
    1.63 +transforming the program into proprietary software.  To prevent this,
    1.64 +we have made it clear that any patent must be licensed for everyone's
    1.65 +free use or not licensed at all.
    1.66 +
    1.67 +  Most GNU software, including some libraries, is covered by the ordinary
    1.68 +GNU General Public License, which was designed for utility programs.  This
    1.69 +license, the GNU Library General Public License, applies to certain
    1.70 +designated libraries.  This license is quite different from the ordinary
    1.71 +one; be sure to read it in full, and don't assume that anything in it is
    1.72 +the same as in the ordinary license.
    1.73 +
    1.74 +  The reason we have a separate public license for some libraries is that
    1.75 +they blur the distinction we usually make between modifying or adding to a
    1.76 +program and simply using it.  Linking a program with a library, without
    1.77 +changing the library, is in some sense simply using the library, and is
    1.78 +analogous to running a utility program or application program.  However, in
    1.79 +a textual and legal sense, the linked executable is a combined work, a
    1.80 +derivative of the original library, and the ordinary General Public License
    1.81 +treats it as such.
    1.82 +
    1.83 +  Because of this blurred distinction, using the ordinary General
    1.84 +Public License for libraries did not effectively promote software
    1.85 +sharing, because most developers did not use the libraries.  We
    1.86 +concluded that weaker conditions might promote sharing better.
    1.87 +
    1.88 +  However, unrestricted linking of non-free programs would deprive the
    1.89 +users of those programs of all benefit from the free status of the
    1.90 +libraries themselves.  This Library General Public License is intended to
    1.91 +permit developers of non-free programs to use free libraries, while
    1.92 +preserving your freedom as a user of such programs to change the free
    1.93 +libraries that are incorporated in them.  (We have not seen how to achieve
    1.94 +this as regards changes in header files, but we have achieved it as regards
    1.95 +changes in the actual functions of the Library.)  The hope is that this
    1.96 +will lead to faster development of free libraries.
    1.97 +
    1.98 +  The precise terms and conditions for copying, distribution and
    1.99 +modification follow.  Pay close attention to the difference between a
   1.100 +"work based on the library" and a "work that uses the library".  The
   1.101 +former contains code derived from the library, while the latter only
   1.102 +works together with the library.
   1.103 +
   1.104 +  Note that it is possible for a library to be covered by the ordinary
   1.105 +General Public License rather than by this special one.
   1.106 +
   1.107 +		  GNU LIBRARY GENERAL PUBLIC LICENSE
   1.108 +   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
   1.109 +
   1.110 +  0. This License Agreement applies to any software library which
   1.111 +contains a notice placed by the copyright holder or other authorized
   1.112 +party saying it may be distributed under the terms of this Library
   1.113 +General Public License (also called "this License").  Each licensee is
   1.114 +addressed as "you".
   1.115 +
   1.116 +  A "library" means a collection of software functions and/or data
   1.117 +prepared so as to be conveniently linked with application programs
   1.118 +(which use some of those functions and data) to form executables.
   1.119 +
   1.120 +  The "Library", below, refers to any such software library or work
   1.121 +which has been distributed under these terms.  A "work based on the
   1.122 +Library" means either the Library or any derivative work under
   1.123 +copyright law: that is to say, a work containing the Library or a
   1.124 +portion of it, either verbatim or with modifications and/or translated
   1.125 +straightforwardly into another language.  (Hereinafter, translation is
   1.126 +included without limitation in the term "modification".)
   1.127 +
   1.128 +  "Source code" for a work means the preferred form of the work for
   1.129 +making modifications to it.  For a library, complete source code means
   1.130 +all the source code for all modules it contains, plus any associated
   1.131 +interface definition files, plus the scripts used to control compilation
   1.132 +and installation of the library.
   1.133 +
   1.134 +  Activities other than copying, distribution and modification are not
   1.135 +covered by this License; they are outside its scope.  The act of
   1.136 +running a program using the Library is not restricted, and output from
   1.137 +such a program is covered only if its contents constitute a work based
   1.138 +on the Library (independent of the use of the Library in a tool for
   1.139 +writing it).  Whether that is true depends on what the Library does
   1.140 +and what the program that uses the Library does.
   1.141 +  
   1.142 +  1. You may copy and distribute verbatim copies of the Library's
   1.143 +complete source code as you receive it, in any medium, provided that
   1.144 +you conspicuously and appropriately publish on each copy an
   1.145 +appropriate copyright notice and disclaimer of warranty; keep intact
   1.146 +all the notices that refer to this License and to the absence of any
   1.147 +warranty; and distribute a copy of this License along with the
   1.148 +Library.
   1.149 +
   1.150 +  You may charge a fee for the physical act of transferring a copy,
   1.151 +and you may at your option offer warranty protection in exchange for a
   1.152 +fee.
   1.153 +
   1.154 +  2. You may modify your copy or copies of the Library or any portion
   1.155 +of it, thus forming a work based on the Library, and copy and
   1.156 +distribute such modifications or work under the terms of Section 1
   1.157 +above, provided that you also meet all of these conditions:
   1.158 +
   1.159 +    a) The modified work must itself be a software library.
   1.160 +
   1.161 +    b) You must cause the files modified to carry prominent notices
   1.162 +    stating that you changed the files and the date of any change.
   1.163 +
   1.164 +    c) You must cause the whole of the work to be licensed at no
   1.165 +    charge to all third parties under the terms of this License.
   1.166 +
   1.167 +    d) If a facility in the modified Library refers to a function or a
   1.168 +    table of data to be supplied by an application program that uses
   1.169 +    the facility, other than as an argument passed when the facility
   1.170 +    is invoked, then you must make a good faith effort to ensure that,
   1.171 +    in the event an application does not supply such function or
   1.172 +    table, the facility still operates, and performs whatever part of
   1.173 +    its purpose remains meaningful.
   1.174 +
   1.175 +    (For example, a function in a library to compute square roots has
   1.176 +    a purpose that is entirely well-defined independent of the
   1.177 +    application.  Therefore, Subsection 2d requires that any
   1.178 +    application-supplied function or table used by this function must
   1.179 +    be optional: if the application does not supply it, the square
   1.180 +    root function must still compute square roots.)
   1.181 +
   1.182 +These requirements apply to the modified work as a whole.  If
   1.183 +identifiable sections of that work are not derived from the Library,
   1.184 +and can be reasonably considered independent and separate works in
   1.185 +themselves, then this License, and its terms, do not apply to those
   1.186 +sections when you distribute them as separate works.  But when you
   1.187 +distribute the same sections as part of a whole which is a work based
   1.188 +on the Library, the distribution of the whole must be on the terms of
   1.189 +this License, whose permissions for other licensees extend to the
   1.190 +entire whole, and thus to each and every part regardless of who wrote
   1.191 +it.
   1.192 +
   1.193 +Thus, it is not the intent of this section to claim rights or contest
   1.194 +your rights to work written entirely by you; rather, the intent is to
   1.195 +exercise the right to control the distribution of derivative or
   1.196 +collective works based on the Library.
   1.197 +
   1.198 +In addition, mere aggregation of another work not based on the Library
   1.199 +with the Library (or with a work based on the Library) on a volume of
   1.200 +a storage or distribution medium does not bring the other work under
   1.201 +the scope of this License.
   1.202 +
   1.203 +  3. You may opt to apply the terms of the ordinary GNU General Public
   1.204 +License instead of this License to a given copy of the Library.  To do
   1.205 +this, you must alter all the notices that refer to this License, so
   1.206 +that they refer to the ordinary GNU General Public License, version 2,
   1.207 +instead of to this License.  (If a newer version than version 2 of the
   1.208 +ordinary GNU General Public License has appeared, then you can specify
   1.209 +that version instead if you wish.)  Do not make any other change in
   1.210 +these notices.
   1.211 +
   1.212 +  Once this change is made in a given copy, it is irreversible for
   1.213 +that copy, so the ordinary GNU General Public License applies to all
   1.214 +subsequent copies and derivative works made from that copy.
   1.215 +
   1.216 +  This option is useful when you wish to copy part of the code of
   1.217 +the Library into a program that is not a library.
   1.218 +
   1.219 +  4. You may copy and distribute the Library (or a portion or
   1.220 +derivative of it, under Section 2) in object code or executable form
   1.221 +under the terms of Sections 1 and 2 above provided that you accompany
   1.222 +it with the complete corresponding machine-readable source code, which
   1.223 +must be distributed under the terms of Sections 1 and 2 above on a
   1.224 +medium customarily used for software interchange.
   1.225 +
   1.226 +  If distribution of object code is made by offering access to copy
   1.227 +from a designated place, then offering equivalent access to copy the
   1.228 +source code from the same place satisfies the requirement to
   1.229 +distribute the source code, even though third parties are not
   1.230 +compelled to copy the source along with the object code.
   1.231 +
   1.232 +  5. A program that contains no derivative of any portion of the
   1.233 +Library, but is designed to work with the Library by being compiled or
   1.234 +linked with it, is called a "work that uses the Library".  Such a
   1.235 +work, in isolation, is not a derivative work of the Library, and
   1.236 +therefore falls outside the scope of this License.
   1.237 +
   1.238 +  However, linking a "work that uses the Library" with the Library
   1.239 +creates an executable that is a derivative of the Library (because it
   1.240 +contains portions of the Library), rather than a "work that uses the
   1.241 +library".  The executable is therefore covered by this License.
   1.242 +Section 6 states terms for distribution of such executables.
   1.243 +
   1.244 +  When a "work that uses the Library" uses material from a header file
   1.245 +that is part of the Library, the object code for the work may be a
   1.246 +derivative work of the Library even though the source code is not.
   1.247 +Whether this is true is especially significant if the work can be
   1.248 +linked without the Library, or if the work is itself a library.  The
   1.249 +threshold for this to be true is not precisely defined by law.
   1.250 +
   1.251 +  If such an object file uses only numerical parameters, data
   1.252 +structure layouts and accessors, and small macros and small inline
   1.253 +functions (ten lines or less in length), then the use of the object
   1.254 +file is unrestricted, regardless of whether it is legally a derivative
   1.255 +work.  (Executables containing this object code plus portions of the
   1.256 +Library will still fall under Section 6.)
   1.257 +
   1.258 +  Otherwise, if the work is a derivative of the Library, you may
   1.259 +distribute the object code for the work under the terms of Section 6.
   1.260 +Any executables containing that work also fall under Section 6,
   1.261 +whether or not they are linked directly with the Library itself.
   1.262 +
   1.263 +  6. As an exception to the Sections above, you may also compile or
   1.264 +link a "work that uses the Library" with the Library to produce a
   1.265 +work containing portions of the Library, and distribute that work
   1.266 +under terms of your choice, provided that the terms permit
   1.267 +modification of the work for the customer's own use and reverse
   1.268 +engineering for debugging such modifications.
   1.269 +
   1.270 +  You must give prominent notice with each copy of the work that the
   1.271 +Library is used in it and that the Library and its use are covered by
   1.272 +this License.  You must supply a copy of this License.  If the work
   1.273 +during execution displays copyright notices, you must include the
   1.274 +copyright notice for the Library among them, as well as a reference
   1.275 +directing the user to the copy of this License.  Also, you must do one
   1.276 +of these things:
   1.277 +
   1.278 +    a) Accompany the work with the complete corresponding
   1.279 +    machine-readable source code for the Library including whatever
   1.280 +    changes were used in the work (which must be distributed under
   1.281 +    Sections 1 and 2 above); and, if the work is an executable linked
   1.282 +    with the Library, with the complete machine-readable "work that
   1.283 +    uses the Library", as object code and/or source code, so that the
   1.284 +    user can modify the Library and then relink to produce a modified
   1.285 +    executable containing the modified Library.  (It is understood
   1.286 +    that the user who changes the contents of definitions files in the
   1.287 +    Library will not necessarily be able to recompile the application
   1.288 +    to use the modified definitions.)
   1.289 +
   1.290 +    b) Accompany the work with a written offer, valid for at
   1.291 +    least three years, to give the same user the materials
   1.292 +    specified in Subsection 6a, above, for a charge no more
   1.293 +    than the cost of performing this distribution.
   1.294 +
   1.295 +    c) If distribution of the work is made by offering access to copy
   1.296 +    from a designated place, offer equivalent access to copy the above
   1.297 +    specified materials from the same place.
   1.298 +
   1.299 +    d) Verify that the user has already received a copy of these
   1.300 +    materials or that you have already sent this user a copy.
   1.301 +
   1.302 +  For an executable, the required form of the "work that uses the
   1.303 +Library" must include any data and utility programs needed for
   1.304 +reproducing the executable from it.  However, as a special exception,
   1.305 +the source code distributed need not include anything that is normally
   1.306 +distributed (in either source or binary form) with the major
   1.307 +components (compiler, kernel, and so on) of the operating system on
   1.308 +which the executable runs, unless that component itself accompanies
   1.309 +the executable.
   1.310 +
   1.311 +  It may happen that this requirement contradicts the license
   1.312 +restrictions of other proprietary libraries that do not normally
   1.313 +accompany the operating system.  Such a contradiction means you cannot
   1.314 +use both them and the Library together in an executable that you
   1.315 +distribute.
   1.316 +
   1.317 +  7. You may place library facilities that are a work based on the
   1.318 +Library side-by-side in a single library together with other library
   1.319 +facilities not covered by this License, and distribute such a combined
   1.320 +library, provided that the separate distribution of the work based on
   1.321 +the Library and of the other library facilities is otherwise
   1.322 +permitted, and provided that you do these two things:
   1.323 +
   1.324 +    a) Accompany the combined library with a copy of the same work
   1.325 +    based on the Library, uncombined with any other library
   1.326 +    facilities.  This must be distributed under the terms of the
   1.327 +    Sections above.
   1.328 +
   1.329 +    b) Give prominent notice with the combined library of the fact
   1.330 +    that part of it is a work based on the Library, and explaining
   1.331 +    where to find the accompanying uncombined form of the same work.
   1.332 +
   1.333 +  8. You may not copy, modify, sublicense, link with, or distribute
   1.334 +the Library except as expressly provided under this License.  Any
   1.335 +attempt otherwise to copy, modify, sublicense, link with, or
   1.336 +distribute the Library is void, and will automatically terminate your
   1.337 +rights under this License.  However, parties who have received copies,
   1.338 +or rights, from you under this License will not have their licenses
   1.339 +terminated so long as such parties remain in full compliance.
   1.340 +
   1.341 +  9. You are not required to accept this License, since you have not
   1.342 +signed it.  However, nothing else grants you permission to modify or
   1.343 +distribute the Library or its derivative works.  These actions are
   1.344 +prohibited by law if you do not accept this License.  Therefore, by
   1.345 +modifying or distributing the Library (or any work based on the
   1.346 +Library), you indicate your acceptance of this License to do so, and
   1.347 +all its terms and conditions for copying, distributing or modifying
   1.348 +the Library or works based on it.
   1.349 +
   1.350 +  10. Each time you redistribute the Library (or any work based on the
   1.351 +Library), the recipient automatically receives a license from the
   1.352 +original licensor to copy, distribute, link with or modify the Library
   1.353 +subject to these terms and conditions.  You may not impose any further
   1.354 +restrictions on the recipients' exercise of the rights granted herein.
   1.355 +You are not responsible for enforcing compliance by third parties to
   1.356 +this License.
   1.357 +
   1.358 +  11. If, as a consequence of a court judgment or allegation of patent
   1.359 +infringement or for any other reason (not limited to patent issues),
   1.360 +conditions are imposed on you (whether by court order, agreement or
   1.361 +otherwise) that contradict the conditions of this License, they do not
   1.362 +excuse you from the conditions of this License.  If you cannot
   1.363 +distribute so as to satisfy simultaneously your obligations under this
   1.364 +License and any other pertinent obligations, then as a consequence you
   1.365 +may not distribute the Library at all.  For example, if a patent
   1.366 +license would not permit royalty-free redistribution of the Library by
   1.367 +all those who receive copies directly or indirectly through you, then
   1.368 +the only way you could satisfy both it and this License would be to
   1.369 +refrain entirely from distribution of the Library.
   1.370 +
   1.371 +If any portion of this section is held invalid or unenforceable under any
   1.372 +particular circumstance, the balance of the section is intended to apply,
   1.373 +and the section as a whole is intended to apply in other circumstances.
   1.374 +
   1.375 +It is not the purpose of this section to induce you to infringe any
   1.376 +patents or other property right claims or to contest validity of any
   1.377 +such claims; this section has the sole purpose of protecting the
   1.378 +integrity of the free software distribution system which is
   1.379 +implemented by public license practices.  Many people have made
   1.380 +generous contributions to the wide range of software distributed
   1.381 +through that system in reliance on consistent application of that
   1.382 +system; it is up to the author/donor to decide if he or she is willing
   1.383 +to distribute software through any other system and a licensee cannot
   1.384 +impose that choice.
   1.385 +
   1.386 +This section is intended to make thoroughly clear what is believed to
   1.387 +be a consequence of the rest of this License.
   1.388 +
   1.389 +  12. If the distribution and/or use of the Library is restricted in
   1.390 +certain countries either by patents or by copyrighted interfaces, the
   1.391 +original copyright holder who places the Library under this License may add
   1.392 +an explicit geographical distribution limitation excluding those countries,
   1.393 +so that distribution is permitted only in or among countries not thus
   1.394 +excluded.  In such case, this License incorporates the limitation as if
   1.395 +written in the body of this License.
   1.396 +
   1.397 +  13. The Free Software Foundation may publish revised and/or new
   1.398 +versions of the Library General Public License from time to time.
   1.399 +Such new versions will be similar in spirit to the present version,
   1.400 +but may differ in detail to address new problems or concerns.
   1.401 +
   1.402 +Each version is given a distinguishing version number.  If the Library
   1.403 +specifies a version number of this License which applies to it and
   1.404 +"any later version", you have the option of following the terms and
   1.405 +conditions either of that version or of any later version published by
   1.406 +the Free Software Foundation.  If the Library does not specify a
   1.407 +license version number, you may choose any version ever published by
   1.408 +the Free Software Foundation.
   1.409 +
   1.410 +  14. If you wish to incorporate parts of the Library into other free
   1.411 +programs whose distribution conditions are incompatible with these,
   1.412 +write to the author to ask for permission.  For software which is
   1.413 +copyrighted by the Free Software Foundation, write to the Free
   1.414 +Software Foundation; we sometimes make exceptions for this.  Our
   1.415 +decision will be guided by the two goals of preserving the free status
   1.416 +of all derivatives of our free software and of promoting the sharing
   1.417 +and reuse of software generally.
   1.418 +
   1.419 +			    NO WARRANTY
   1.420 +
   1.421 +  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
   1.422 +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
   1.423 +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
   1.424 +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
   1.425 +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
   1.426 +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
   1.427 +PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
   1.428 +LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
   1.429 +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
   1.430 +
   1.431 +  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
   1.432 +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
   1.433 +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
   1.434 +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
   1.435 +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
   1.436 +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
   1.437 +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
   1.438 +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
   1.439 +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
   1.440 +DAMAGES.
   1.441 +

   1.444 +     Appendix: How to Apply These Terms to Your New Libraries
   1.445 +
   1.446 +  If you develop a new library, and you want it to be of the greatest
   1.447 +possible use to the public, we recommend making it free software that
   1.448 +everyone can redistribute and change.  You can do so by permitting
   1.449 +redistribution under these terms (or, alternatively, under the terms of the
   1.450 +ordinary General Public License).
   1.451 +
   1.452 +  To apply these terms, attach the following notices to the library.  It is
   1.453 +safest to attach them to the start of each source file to most effectively
   1.454 +convey the exclusion of warranty; and each file should have at least the
   1.455 +"copyright" line and a pointer to where the full notice is found.
   1.456 +
   1.457 +    <one line to give the library's name and a brief idea of what it does.>
   1.458 +    Copyright (C) <year>  <name of author>
   1.459 +
   1.460 +    This library is free software; you can redistribute it and/or
   1.461 +    modify it under the terms of the GNU Library General Public
   1.462 +    License as published by the Free Software Foundation; either
   1.463 +    version 2 of the License, or (at your option) any later version.
   1.464 +
   1.465 +    This library is distributed in the hope that it will be useful,
   1.466 +    but WITHOUT ANY WARRANTY; without even the implied warranty of
   1.467 +    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
   1.468 +    Library General Public License for more details.
   1.469 +
   1.470 +    You should have received a copy of the GNU Library General Public
   1.471 +    License along with this library; if not, write to the Free
   1.472 +    Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
   1.473 +
   1.474 +Also add information on how to contact you by electronic and paper mail.
   1.475 +
   1.476 +You should also get your employer (if you work as a programmer) or your
   1.477 +school, if any, to sign a "copyright disclaimer" for the library, if
   1.478 +necessary.  Here is a sample; alter the names:
   1.479 +
   1.480 +  Yoyodyne, Inc., hereby disclaims all copyright interest in the
   1.481 +  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
