		8	+We make use of section 3 of the GNU Library General Public License
		9	+('...opt to apply the terms of the ordinary GNU General Public License...'),

		24	+ GNU LIBRARY GENERAL PUBLIC LICENSE
		25	+ Version 2, June 1991
		26	+
		27	+ Copyright (C) 1991 Free Software Foundation, Inc.
		28	+ 675 Mass Ave, Cambridge, MA 02139, USA
		29	+ Everyone is permitted to copy and distribute verbatim copies
		30	+ of this license document, but changing it is not allowed.
		31	+
		32	+[This is the first released version of the library GPL. It is
		33	+ numbered 2 because it goes with version 2 of the ordinary GPL.]
		34	+
		35	+ Preamble
		36	+
		37	+ The licenses for most software are designed to take away your
		38	+freedom to share and change it. By contrast, the GNU General Public
		39	+Licenses are intended to guarantee your freedom to share and change
		40	+free software--to make sure the software is free for all its users.
		41	+
		42	+ This license, the Library General Public License, applies to some
		43	+specially designated Free Software Foundation software, and to any
		44	+other libraries whose authors decide to use it. You can use it for
		45	+your libraries, too.
		46	+
		47	+ When we speak of free software, we are referring to freedom, not
		48	+price. Our General Public Licenses are designed to make sure that you
		49	+have the freedom to distribute copies of free software (and charge for
		50	+this service if you wish), that you receive source code or can get it
		51	+if you want it, that you can change the software or use pieces of it
		52	+in new free programs; and that you know you can do these things.
		53	+
		54	+ To protect your rights, we need to make restrictions that forbid
		55	+anyone to deny you these rights or to ask you to surrender the rights.
		56	+These restrictions translate to certain responsibilities for you if
		57	+you distribute copies of the library, or if you modify it.
		58	+
		59	+ For example, if you distribute copies of the library, whether gratis
		60	+or for a fee, you must give the recipients all the rights that we gave
		61	+you. You must make sure that they, too, receive or can get the source
		62	+code. If you link a program with the library, you must provide
		63	+complete object files to the recipients so that they can relink them
		64	+with the library, after making changes to the library and recompiling
		65	+it. And you must show them these terms so they know their rights.
		66	+
		67	+ Our method of protecting your rights has two steps: (1) copyright
		68	+the library, and (2) offer you this license which gives you legal
		69	+permission to copy, distribute and/or modify the library.
		70	+
		71	+ Also, for each distributor's protection, we want to make certain
		72	+that everyone understands that there is no warranty for this free
		73	+library. If the library is modified by someone else and passed on, we
		74	+want its recipients to know that what they have is not the original
		75	+version, so that any problems introduced by others will not reflect on
		76	+the original authors' reputations.
		77	+
		78	+ Finally, any free program is threatened constantly by software
		79	+patents. We wish to avoid the danger that companies distributing free
		80	+software will individually obtain patent licenses, thus in effect
		81	+transforming the program into proprietary software. To prevent this,
		82	+we have made it clear that any patent must be licensed for everyone's
		83	+free use or not licensed at all.
		84	+
		85	+ Most GNU software, including some libraries, is covered by the ordinary
		86	+GNU General Public License, which was designed for utility programs. This
		87	+license, the GNU Library General Public License, applies to certain
		88	+designated libraries. This license is quite different from the ordinary
		89	+one; be sure to read it in full, and don't assume that anything in it is
		90	+the same as in the ordinary license.
		91	+
		92	+ The reason we have a separate public license for some libraries is that
		93	+they blur the distinction we usually make between modifying or adding to a
		94	+program and simply using it. Linking a program with a library, without
		95	+changing the library, is in some sense simply using the library, and is
		96	+analogous to running a utility program or application program. However, in
		97	+a textual and legal sense, the linked executable is a combined work, a
		98	+derivative of the original library, and the ordinary General Public License
		99	+treats it as such.
		100	+
		101	+ Because of this blurred distinction, using the ordinary General
		102	+Public License for libraries did not effectively promote software
		103	+sharing, because most developers did not use the libraries. We
		104	+concluded that weaker conditions might promote sharing better.
		105	+
		106	+ However, unrestricted linking of non-free programs would deprive the
		107	+users of those programs of all benefit from the free status of the
		108	+libraries themselves. This Library General Public License is intended to
		109	+permit developers of non-free programs to use free libraries, while
		110	+preserving your freedom as a user of such programs to change the free
		111	+libraries that are incorporated in them. (We have not seen how to achieve
		112	+this as regards changes in header files, but we have achieved it as regards
		113	+changes in the actual functions of the Library.) The hope is that this
		114	+will lead to faster development of free libraries.
		115	+
		116	+ The precise terms and conditions for copying, distribution and
		117	+modification follow. Pay close attention to the difference between a
		118	+"work based on the library" and a "work that uses the library". The
		119	+former contains code derived from the library, while the latter only
		120	+works together with the library.
		121	+
		122	+ Note that it is possible for a library to be covered by the ordinary
		123	+General Public License rather than by this special one.
		124	+
		125	+ GNU LIBRARY GENERAL PUBLIC LICENSE
		126	+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
		127	+
		128	+ 0. This License Agreement applies to any software library which
		129	+contains a notice placed by the copyright holder or other authorized
		130	+party saying it may be distributed under the terms of this Library
		131	+General Public License (also called "this License"). Each licensee is
		132	+addressed as "you".
		133	+
		134	+ A "library" means a collection of software functions and/or data
		135	+prepared so as to be conveniently linked with application programs
		136	+(which use some of those functions and data) to form executables.
		137	+
		138	+ The "Library", below, refers to any such software library or work
		139	+which has been distributed under these terms. A "work based on the
		140	+Library" means either the Library or any derivative work under
		141	+copyright law: that is to say, a work containing the Library or a
		142	+portion of it, either verbatim or with modifications and/or translated
		143	+straightforwardly into another language. (Hereinafter, translation is
		144	+included without limitation in the term "modification".)
		145	+
		146	+ "Source code" for a work means the preferred form of the work for
		147	+making modifications to it. For a library, complete source code means
		148	+all the source code for all modules it contains, plus any associated
		149	+interface definition files, plus the scripts used to control compilation
		150	+and installation of the library.
		151	+
		152	+ Activities other than copying, distribution and modification are not
		153	+covered by this License; they are outside its scope. The act of
		154	+running a program using the Library is not restricted, and output from
		155	+such a program is covered only if its contents constitute a work based
		156	+on the Library (independent of the use of the Library in a tool for
		157	+writing it). Whether that is true depends on what the Library does
		158	+and what the program that uses the Library does.
		159	+
		160	+ 1. You may copy and distribute verbatim copies of the Library's
		161	+complete source code as you receive it, in any medium, provided that
		162	+you conspicuously and appropriately publish on each copy an
		163	+appropriate copyright notice and disclaimer of warranty; keep intact
		164	+all the notices that refer to this License and to the absence of any
		165	+warranty; and distribute a copy of this License along with the
		166	+Library.
		167	+
		168	+ You may charge a fee for the physical act of transferring a copy,
		169	+and you may at your option offer warranty protection in exchange for a
		170	+fee.
		171	+
		172	+ 2. You may modify your copy or copies of the Library or any portion
		173	+of it, thus forming a work based on the Library, and copy and
		174	+distribute such modifications or work under the terms of Section 1
		175	+above, provided that you also meet all of these conditions:
		176	+
		177	+ a) The modified work must itself be a software library.
		178	+
		179	+ b) You must cause the files modified to carry prominent notices
		180	+ stating that you changed the files and the date of any change.
		181	+
		182	+ c) You must cause the whole of the work to be licensed at no
		183	+ charge to all third parties under the terms of this License.
		184	+
		185	+ d) If a facility in the modified Library refers to a function or a
		186	+ table of data to be supplied by an application program that uses
		187	+ the facility, other than as an argument passed when the facility
		188	+ is invoked, then you must make a good faith effort to ensure that,
		189	+ in the event an application does not supply such function or
		190	+ table, the facility still operates, and performs whatever part of
		191	+ its purpose remains meaningful.
		192	+
		193	+ (For example, a function in a library to compute square roots has
		194	+ a purpose that is entirely well-defined independent of the
		195	+ application. Therefore, Subsection 2d requires that any
		196	+ application-supplied function or table used by this function must
		197	+ be optional: if the application does not supply it, the square
		198	+ root function must still compute square roots.)
		199	+
		200	+These requirements apply to the modified work as a whole. If
		201	+identifiable sections of that work are not derived from the Library,
		202	+and can be reasonably considered independent and separate works in
		203	+themselves, then this License, and its terms, do not apply to those
		204	+sections when you distribute them as separate works. But when you
		205	+distribute the same sections as part of a whole which is a work based
		206	+on the Library, the distribution of the whole must be on the terms of
		207	+this License, whose permissions for other licensees extend to the
		208	+entire whole, and thus to each and every part regardless of who wrote
		209	+it.
		210	+
		211	+Thus, it is not the intent of this section to claim rights or contest
		212	+your rights to work written entirely by you; rather, the intent is to
		213	+exercise the right to control the distribution of derivative or
		214	+collective works based on the Library.
		215	+
		216	+In addition, mere aggregation of another work not based on the Library
		217	+with the Library (or with a work based on the Library) on a volume of
		218	+a storage or distribution medium does not bring the other work under
		219	+the scope of this License.
		220	+
		221	+ 3. You may opt to apply the terms of the ordinary GNU General Public
		222	+License instead of this License to a given copy of the Library. To do
		223	+this, you must alter all the notices that refer to this License, so
		224	+that they refer to the ordinary GNU General Public License, version 2,
		225	+instead of to this License. (If a newer version than version 2 of the
		226	+ordinary GNU General Public License has appeared, then you can specify
		227	+that version instead if you wish.) Do not make any other change in
		228	+these notices.
		229	+
		230	+ Once this change is made in a given copy, it is irreversible for
		231	+that copy, so the ordinary GNU General Public License applies to all
		232	+subsequent copies and derivative works made from that copy.
		233	+
		234	+ This option is useful when you wish to copy part of the code of
		235	+the Library into a program that is not a library.
		236	+
		237	+ 4. You may copy and distribute the Library (or a portion or
		238	+derivative of it, under Section 2) in object code or executable form
		239	+under the terms of Sections 1 and 2 above provided that you accompany
		240	+it with the complete corresponding machine-readable source code, which
		241	+must be distributed under the terms of Sections 1 and 2 above on a
		242	+medium customarily used for software interchange.
		243	+
		244	+ If distribution of object code is made by offering access to copy
		245	+from a designated place, then offering equivalent access to copy the
		246	+source code from the same place satisfies the requirement to
		247	+distribute the source code, even though third parties are not
		248	+compelled to copy the source along with the object code.
		249	+
		250	+ 5. A program that contains no derivative of any portion of the
		251	+Library, but is designed to work with the Library by being compiled or
		252	+linked with it, is called a "work that uses the Library". Such a
		253	+work, in isolation, is not a derivative work of the Library, and
		254	+therefore falls outside the scope of this License.
		255	+
		256	+ However, linking a "work that uses the Library" with the Library
		257	+creates an executable that is a derivative of the Library (because it
		258	+contains portions of the Library), rather than a "work that uses the
		259	+library". The executable is therefore covered by this License.
		260	+Section 6 states terms for distribution of such executables.
		261	+
		262	+ When a "work that uses the Library" uses material from a header file
		263	+that is part of the Library, the object code for the work may be a
		264	+derivative work of the Library even though the source code is not.
		265	+Whether this is true is especially significant if the work can be
		266	+linked without the Library, or if the work is itself a library. The
		267	+threshold for this to be true is not precisely defined by law.
		268	+
		269	+ If such an object file uses only numerical parameters, data
		270	+structure layouts and accessors, and small macros and small inline
		271	+functions (ten lines or less in length), then the use of the object
		272	+file is unrestricted, regardless of whether it is legally a derivative
		273	+work. (Executables containing this object code plus portions of the
		274	+Library will still fall under Section 6.)
		275	+
		276	+ Otherwise, if the work is a derivative of the Library, you may
		277	+distribute the object code for the work under the terms of Section 6.
		278	+Any executables containing that work also fall under Section 6,
		279	+whether or not they are linked directly with the Library itself.
		280	+
		281	+ 6. As an exception to the Sections above, you may also compile or
		282	+link a "work that uses the Library" with the Library to produce a
		283	+work containing portions of the Library, and distribute that work
		284	+under terms of your choice, provided that the terms permit
		285	+modification of the work for the customer's own use and reverse
		286	+engineering for debugging such modifications.
		287	+
		288	+ You must give prominent notice with each copy of the work that the
		289	+Library is used in it and that the Library and its use are covered by
		290	+this License. You must supply a copy of this License. If the work
		291	+during execution displays copyright notices, you must include the
		292	+copyright notice for the Library among them, as well as a reference
		293	+directing the user to the copy of this License. Also, you must do one
		294	+of these things:
		295	+
		296	+ a) Accompany the work with the complete corresponding
		297	+ machine-readable source code for the Library including whatever
		298	+ changes were used in the work (which must be distributed under
		299	+ Sections 1 and 2 above); and, if the work is an executable linked
		300	+ with the Library, with the complete machine-readable "work that
		301	+ uses the Library", as object code and/or source code, so that the
		302	+ user can modify the Library and then relink to produce a modified
		303	+ executable containing the modified Library. (It is understood
		304	+ that the user who changes the contents of definitions files in the
		305	+ Library will not necessarily be able to recompile the application
		306	+ to use the modified definitions.)
		307	+
		308	+ b) Accompany the work with a written offer, valid for at
		309	+ least three years, to give the same user the materials
		310	+ specified in Subsection 6a, above, for a charge no more
		311	+ than the cost of performing this distribution.
		312	+
		313	+ c) 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.
		316	+
		317	+ d) Verify that the user has already received a copy of these
		318	+ materials or that you have already sent this user a copy.
		319	+
		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 source code distributed need not include anything that is normally
		324	+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
		327	+the executable.
		328	+
		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
		333	+distribute.
		334	+
		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:
		341	+
		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
		345	+ Sections above.
		346	+
		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.
		350	+
		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.
		358	+
		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.
		367	+
		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 to
		374	+this License.
		375	+
		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.
		388	+
		389	+If any portion of this section is held invalid or unenforceable under any
		390	+particular circumstance, the balance of the section is intended to apply,
		391	+and the section as a whole is intended to apply in other circumstances.
		392	+
		393	+It is not the purpose of this section to induce you to infringe any
		394	+patents or other property right claims or to contest validity of any
		395	+such claims; this section has the sole purpose of protecting the
		396	+integrity of the free software distribution system which is
		397	+implemented by public license practices. Many people have made
		398	+generous contributions to the wide range of software distributed
		399	+through that system in reliance on consistent application of that
		400	+system; it is up to the author/donor to decide if he or she is willing
		401	+to distribute software through any other system and a licensee cannot
		402	+impose that choice.
		403	+
		404	+This section is intended to make thoroughly clear what is believed to
		405	+be a consequence of the rest of this License.
		406	+
		407	+ 12. If the distribution and/or use of the Library is restricted in
		408	+certain countries either by patents or by copyrighted interfaces, the
		409	+original copyright holder who places the Library under this License may add
		410	+an explicit geographical distribution limitation excluding those countries,
		411	+so that distribution is permitted only in or among countries not thus
		412	+excluded. In such case, this License incorporates the limitation as if
		413	+written in the body of this License.
		414	+
		415	+ 13. The Free Software Foundation may publish revised and/or new
		416	+versions of the Library General Public License from time to time.
		417	+Such new versions will be similar in spirit to the present version,
		418	+but may differ in detail to address new problems or concerns.
		419	+
		420	+Each version is given a distinguishing version number. If the Library
		421	+specifies a version number of this License which applies to it and
		422	+"any later version", you have the option of following the terms and
		423	+conditions either of that version or of any later version published by
		424	+the Free Software Foundation. If the Library does not specify a
		425	+license version number, you may choose any version ever published by
		426	+the Free Software Foundation.
		427	+
		428	+ 14. If you wish to incorporate parts of the Library into other free
		429	+programs whose distribution conditions are incompatible with these,
		430	+write to the author to ask for permission. For software which is
		431	+copyrighted by the Free Software Foundation, write to the Free
		432	+Software Foundation; we sometimes make exceptions for this. Our
		433	+decision will be guided by the two goals of preserving the free status
		434	+of all derivatives of our free software and of promoting the sharing
		435	+and reuse of software generally.
		436	+
		437	+ NO WARRANTY
		438	+
		439	+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
		440	+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
		441	+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
		442	+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
		443	+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
		444	+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
		445	+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE

		448	+

		460	+ END OF TERMS AND CONDITIONS
		461	+
		462	+ Appendix: How to Apply These Terms to Your New Libraries
		463	+
		464	+ If you develop a new library, and you want it to be of the greatest
		465	+possible use to the public, we recommend making it free software that
		466	+everyone can redistribute and change. You can do so by permitting
		467	+redistribution under these terms (or, alternatively, under the terms of the
		468	+ordinary General Public License).
		469	+
		470	+ To apply these terms, attach the following notices to the library. It is
		471	+safest to attach them to the start of each source file to most effectively
		472	+convey the exclusion of warranty; and each file should have at least the
		473	+"copyright" line and a pointer to where the full notice is found.
		474	+
		475	+ <one line to give the library's name and a brief idea of what it does.>
		476	+ Copyright (C) <year> <name of author>
		477	+
		478	+ This library is free software; you can redistribute it and/or
		479	+ modify it under the terms of the GNU Library General Public
		480	+ License as published by the Free Software Foundation; either
		481	+ version 2 of the License, or (at your option) any later version.
		482	+
		483	+ This library is distributed in the hope that it will be useful,
		484	+ but WITHOUT ANY WARRANTY; without even the implied warranty of
		485	+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
		486	+ Library General Public License for more details.
		487	+
		488	+ You should have received a copy of the GNU Library General Public
		489	+ License along with this library; if not, write to the Free
		490	+ Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
		491	+
		492	+Also add information on how to contact you by electronic and paper mail.
		493	+
		494	+You should also get your employer (if you work as a programmer) or your
		495	+school, if any, to sign a "copyright disclaimer" for the library, if
		496	+necessary. Here is a sample; alter the names:
		497	+
		498	+ Yoyodyne, Inc., hereby disclaims all copyright interest in the
		499	+ library `Frob' (a library for tweaking knobs) written by James Random Hacker.
