		"<h3>Version 2, June 1991</h3>"
		"Copyright (C) 1989, 1991 Free Software Foundation, Inc. "
		"51 Franklin Street, 5th Floor, Boston, MA 02110-1301, USA "
		"Everyone is permitted to copy and distribute verbatim copies "
		"of this license document, but changing it is not allowed. "
		"<p>"
		"<h4>Preamble</h4>"
		"<p>"
		"The licenses for most software are designed to take away your "
		"freedom to share and change it.  By contrast, the GNU General Public "
		"License is intended to guarantee your freedom to share and change free "
		"software--to make sure the software is free for all its users.  This "
		"General Public License applies to most of the Free Software "
		"Foundation's software and to any other program whose authors commit to "
		"using it.  (Some other Free Software Foundation software is covered by "
		"the GNU Library General Public License instead.)  You can apply it to "
		"your programs, too. "
		"<p>"
		"When we speak of free software, we are referring to freedom, not "
		"price.  Our General Public Licenses are designed to make sure that you "
		"have the freedom to distribute copies of free software (and charge for "
		"this service if you wish), that you receive source code or can get it "
		"if you want it, that you can change the software or use pieces of it "
		"in new free programs; and that you know you can do these things. "
		"<p>"
		"To protect your rights, we need to make restrictions that forbid "
		"anyone to deny you these rights or to ask you to surrender the rights. "
		"These restrictions translate to certain responsibilities for you if you "
		"distribute copies of the software, or if you modify it. "
		"<p>"
		"For example, if you distribute copies of such a program, whether "
		"gratis or for a fee, you must give the recipients all the rights that "
		"you have.  You must make sure that they, too, receive or can get the "
		"source code.  And you must show them these terms so they know their "
		"rights. "
		"<p>"
		"We protect your rights with two steps: (1) copyright the software, and "
		"(2) offer you this license which gives you legal permission to copy, "
		"distribute and/or modify the software. "
		"<p>"
		"Also, for each author's protection and ours, we want to make certain "
		"that everyone understands that there is no warranty for this free "
		"software.  If the software is modified by someone else and passed on, we "
		"want its recipients to know that what they have is not the original, so "
		"that any problems introduced by others will not reflect on the original "
		"authors' reputations. "
		"<p>"
		"Finally, any free program is threatened constantly by software "
		"patents.  We wish to avoid the danger that redistributors of a free "
		"program will individually obtain patent licenses, in effect making the "
		"program proprietary.  To prevent this, we have made it clear that any "
		"patent must be licensed for everyone's free use or not licensed at all. "
		"<p>"
		"The precise terms and conditions for copying, distribution and "
		"modification follow. "
		"<p>"
		"<h4>GNU GENERAL PUBLIC LICENSE</h4>"
		"TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION "
		"<p>"
		"0. This License applies to any program or other work which contains "
		"a notice placed by the copyright holder saying it may be distributed "
		"under the terms of this General Public License.  The \"Program\", below, "
		"refers to any such program or work, and a \"work based on the Program\"<p>"
		"means either the Program or any derivative work under copyright law: "
		"that is to say, a work containing the Program or a portion of it, "
		"either verbatim or with modifications and/or translated into another "
		"language.  (Hereinafter, translation is included without limitation in "
		"the term \"modification\".)  Each licensee is addressed as \"you\". "
		"<p>"
		"Activities other than copying, distribution and modification are not "
		"covered by this License; they are outside its scope.  The act of "
		"running the Program is not restricted, and the output from the Program "
		"is covered only if its contents constitute a work based on the "
		"Program (independent of having been made by running the Program). "
		"Whether that is true depends on what the Program does. "
		"<p>"
		"1. You may copy and distribute verbatim copies of the Program's "
		"source code as you receive it, in any medium, provided that you "
		"conspicuously and appropriately publish on each copy an appropriate "
		"copyright notice and disclaimer of warranty; keep intact all the "
		"notices that refer to this License and to the absence of any warranty; "
		"and give any other recipients of the Program a copy of this License "
		"along with the Program. "
		"<p>"
		"You may charge a fee for the physical act of transferring a copy, and "
		"you may at your option offer warranty protection in exchange for a fee. "
		"<p>"
		"2. You may modify your copy or copies of the Program or any portion "
		"of it, thus forming a work based on the Program, and copy and "
		"distribute such modifications or work under the terms of Section 1 "
		"above, provided that you also meet all of these conditions: "
		"<p>"
		"a) You must cause the modified files to carry prominent notices "
		"stating that you changed the files and the date of any change. "
		"<p>"
		"b) You must cause any work that you distribute or publish, that in "
		"whole or in part contains or is derived from the Program or any "
		"part thereof, to be licensed as a whole at no charge to all third "
		"parties under the terms of this License. "
		"<p>"
		"c) If the modified program normally reads commands interactively "
		"when run, you must cause it, when started running for such "
		"interactive use in the most ordinary way, to print or display an "
		"announcement including an appropriate copyright notice and a "
		"notice that there is no warranty (or else, saying that you provide "
		"a warranty) and that users may redistribute the program under "
		"these conditions, and telling the user how to view a copy of this "
		"License.  (Exception: if the Program itself is interactive but "
		"does not normally print such an announcement, your work based on "
		"the Program is not required to print an announcement.) "
		"<p>"
		"These requirements apply to the modified work as a whole.  If "
		"identifiable sections of that work are not derived from the Program, "
		"and can be reasonably considered independent and separate works in "
		"themselves, then this License, and its terms, do not apply to those "
		"sections when you distribute them as separate works.  But when you "
		"distribute the same sections as part of a whole which is a work based "
		"on the Program, the distribution of the whole must be on the terms of "
		"this License, whose permissions for other licensees extend to the "
		"entire whole, and thus to each and every part regardless of who wrote it. "
		"<p>"
		"Thus, it is not the intent of this section to claim rights or contest "
		"your rights to work written entirely by you; rather, the intent is to "
		"exercise the right to control the distribution of derivative or "
		"collective works based on the Program. "
		"<p>"
		"In addition, mere aggregation of another work not based on the Program "
		"with the Program (or with a work based on the Program) on a volume of "
		"a storage or distribution medium does not bring the other work under "
		"the scope of this License. "
		"<p>"
		"3. You may copy and distribute the Program (or a work based on it, "
		"under Section 2) in object code or executable form under the terms of "
		"Sections 1 and 2 above provided that you also do one of the following: "
		"<p>"
		"a) Accompany it with the complete corresponding machine-readable "
		"source code, which must be distributed under the terms of Sections "
		"1 and 2 above on a medium customarily used for software interchange; or, "
		"<p>"
		"b) Accompany it with a written offer, valid for at least three "
		"years, to give any third party, for a charge no more than your "
		"cost of physically performing source distribution, a complete "
		"machine-readable copy of the corresponding source code, to be "
		"distributed under the terms of Sections 1 and 2 above on a medium "
		"customarily used for software interchange; or, "
		"<p>"
		"c) Accompany it with the information you received as to the offer "
		"to distribute corresponding source code.  (This alternative is "
		"allowed only for noncommercial distribution and only if you "
		"received the program in object code or executable form with such "
		"an offer, in accord with Subsection b above.) "
		"<p>"
		"The source code for a work means the preferred form of the work for "
		"making modifications to it.  For an executable work, complete source "
		"code means all the source code for all modules it contains, plus any "
		"associated interface definition files, plus the scripts used to "
		"control compilation and installation of the executable.  However, as a "
		"special exception, the source code distributed need not include "
		"anything that is normally distributed (in either source or binary "
		"form) with the major components (compiler, kernel, and so on) of the "
		"operating system on which the executable runs, unless that component "
		"itself accompanies the executable. "
		"<p>"
		"If distribution of executable or object code is made by offering "
		"access to copy from a designated place, then offering equivalent "
		"access to copy the source code from the same place counts as "
		"distribution of the source code, even though third parties are not "
		"compelled to copy the source along with the object code. "
		"<p>"
		"4. You may not copy, modify, sublicense, or distribute the Program "
		"except as expressly provided under this License.  Any attempt "
		"otherwise to copy, modify, sublicense or distribute the Program is "
		"void, and will automatically terminate your rights under this License. "
		"However, parties who have received copies, or rights, from you under "
		"this License will not have their licenses terminated so long as such "
		"parties remain in full compliance. "
		"<p>"
		"5. You are not required to accept this License, since you have not "
		"signed it.  However, nothing else grants you permission to modify or "
		"distribute the Program or its derivative works.  These actions are "
		"prohibited by law if you do not accept this License.  Therefore, by "
		"modifying or distributing the Program (or any work based on the "
		"Program), you indicate your acceptance of this License to do so, and "
		"all its terms and conditions for copying, distributing or modifying "
		"the Program or works based on it. "
		"<p>"
		"6. Each time you redistribute the Program (or any work based on the "
		"Program), the recipient automatically receives a license from the "
		"original licensor to copy, distribute or modify the Program subject to "
		"these terms and conditions.  You may not impose any further "
		"restrictions on the recipients' exercise of the rights granted herein. "
		"You are not responsible for enforcing compliance by third parties to "
		"this License. "
		"<p>"
		"7. If, as a consequence of a court judgment or allegation of patent "
		"infringement or for any other reason (not limited to patent issues), "
		"conditions are imposed on you (whether by court order, agreement or "
		"otherwise) that contradict the conditions of this License, they do not "
		"excuse you from the conditions of this License.  If you cannot "
		"distribute so as to satisfy simultaneously your obligations under this "
		"License and any other pertinent obligations, then as a consequence you "
		"may not distribute the Program at all.  For example, if a patent "
		"license would not permit royalty-free redistribution of the Program by "
		"all those who receive copies directly or indirectly through you, then "
		"the only way you could satisfy both it and this License would be to "
		"refrain entirely from distribution of the Program. "
		"<p>"
		"If any portion of this section is held invalid or unenforceable under "
		"any particular circumstance, the balance of the section is intended to "
		"apply and the section as a whole is intended to apply in other "
		"circumstances. "
		"<p>"
		"It is not the purpose of this section to induce you to infringe any "
		"patents or other property right claims or to contest validity of any "
		"such claims; this section has the sole purpose of protecting the "
		"integrity of the free software distribution system, which is "
		"implemented by public license practices.  Many people have made "
		"generous contributions to the wide range of software distributed "
		"through that system in reliance on consistent application of that "
		"system; it is up to the author/donor to decide if he or she is willing "
		"to distribute software through any other system and a licensee cannot "
		"impose that choice. "
		"<p>"
		"This section is intended to make thoroughly clear what is believed to "
		"be a consequence of the rest of this License. "
		"<p>"
		"8. If the distribution and/or use of the Program is restricted in "
		"certain countries either by patents or by copyrighted interfaces, the "
		"original copyright holder who places the Program under this License "
		"may add an explicit geographical distribution limitation excluding "
		"those countries, so that distribution is permitted only in or among "
		"countries not thus excluded.  In such case, this License incorporates "
		"the limitation as if written in the body of this License. "
		"<p>"
		"9. The Free Software Foundation may publish revised and/or new versions "
		"of the General Public License from time to time.  Such new versions will "
		"be similar in spirit to the present version, but may differ in detail to "
		"address new problems or concerns. "
		"<p>"
		"Each version is given a distinguishing version number.  If the Program "
		"specifies a version number of this License which applies to it and \"any "
		"later version\", you have the option of following the terms and conditions "
		"either of that version or of any later version published by the Free "
		"Software Foundation.  If the Program does not specify a version number of "
		"this License, you may choose any version ever published by the Free Software "
		"Foundation. "
		"<p>"
		"10. If you wish to incorporate parts of the Program into other free "
		"programs whose distribution conditions are different, write to the author "
		"to ask for permission.  For software which is copyrighted by the Free "
		"Software Foundation, write to the Free Software Foundation; we sometimes "
		"make exceptions for this.  Our decision will be guided by the two goals "
		"of preserving the free status of all derivatives of our free software and "
		"of promoting the sharing and reuse of software generally. "
		"<p>"
		"NO WARRANTY "
		"<p>"

		"Copyright (C) 1991, 1999 Free Software Foundation, Inc. "
		"51 Franklin Street, 5th Floor, Boston, MA 02110-1301, USA "
		"Everyone is permitted to copy and distribute verbatim copies "
		"of this license document, but changing it is not allowed. "
		"<p>"
		"[This is the first released version of the Lesser GPL. It also counts "
		"as the successor of the GNU Library Public License, version 2, hence "
		"the version number 2.1.] "
		"<p>"
		"<h4>Preamble</h4>"
		"<p>"
		"The licenses for most software are designed to take away your "
		"freedom to share and change it.  By contrast, the GNU General Public "
		"Licenses are intended to guarantee your freedom to share and change "
		"free software--to make sure the software is free for all its users. "
		"<p>"
		"This license, the Lesser General Public License, applies to some "
		"specially designated software packages--typically libraries--of the "
		"Free Software Foundation and other authors who decide to use it.  You "
		"can use it too, but we suggest you first think carefully about whether "
		"this license or the ordinary General Public License is the better "
		"strategy to use in any particular case, based on the explanations below. "
		"<p>"
		"When we speak of free software, we are referring to freedom of use, "
		"not price.  Our General Public Licenses are designed to make sure that "
		"you have the freedom to distribute copies of free software (and charge "
		"for this service if you wish); that you receive source code or can get "
		"it if you want it; that you can change the software and use pieces of "
		"it in new free programs; and that you are informed that you can do "
		"these things. "
		"<p>"
		"To protect your rights, we need to make restrictions that forbid "
		"distributors to deny you these rights or to ask you to surrender these "
		"rights.  These restrictions translate to certain responsibilities for "
		"you if you distribute copies of the library or if you modify it. "
		"<p>"
		"For example, if you distribute copies of the library, whether gratis "
		"or for a fee, you must give the recipients all the rights that we gave "
		"you.  You must make sure that they, too, receive or can get the source "
		"code.  If you link other code with the library, you must provide "
		"complete object files to the recipients, so that they can relink them "
		"with the library after making changes to the library and recompiling "
		"it.  And you must show them these terms so they know their rights. "
		"<p>"
		"We protect your rights with a two-step method: (1) we copyright the "
		"library, and (2) we offer you this license, which gives you legal "
		"permission to copy, distribute and/or modify the library. "
		"<p>"
		"To protect each distributor, we want to make it very clear that "
		"there is no warranty for the free library.  Also, if the library is "
		"modified by someone else and passed on, the recipients should know "
		"that what they have is not the original version, so that the original "
		"author\'s reputation will not be affected by problems that might be "
		"introduced by others. "
		"<p>"
		"Finally, software patents pose a constant threat to the existence of "
		"any free program.  We wish to make sure that a company cannot "
		"effectively restrict the users of a free program by obtaining a "
		"restrictive license from a patent holder.  Therefore, we insist that "
		"any patent license obtained for a version of the library must be "
		"consistent with the full freedom of use specified in this license. "
		"<p>"
		"Most GNU software, including some libraries, is covered by the "
		"ordinary GNU General Public License.  This license, the GNU Lesser "
		"General Public License, applies to certain designated libraries, and "
		"is quite different from the ordinary General Public License.  We use "
		"this license for certain libraries in order to permit linking those "
		"libraries into non-free programs. "
		"<p>"
		"When a program is linked with a library, whether statically or using "
		"a shared library, the combination of the two is legally speaking a "
		"combined work, a derivative of the original library.  The ordinary "
		"General Public License therefore permits such linking only if the "
		"entire combination fits its criteria of freedom.  The Lesser General "
		"Public License permits more lax criteria for linking other code with "
		"the library. "
		"<p>"
		"We call this license the \"Lesser\" General Public License because it "
		"does Less to protect the user\'s freedom than the ordinary General "
		"Public License.  It also provides other free software developers Less "
		"of an advantage over competing non-free programs.  These disadvantages "
		"are the reason we use the ordinary General Public License for many "
		"libraries.  However, the Lesser license provides advantages in certain "
		"special circumstances. "
		"<p>"
		"For example, on rare occasions, there may be a special need to "
		"encourage the widest possible use of a certain library, so that it becomes "
		"a de-facto standard.  To achieve this, non-free programs must be "
		"allowed to use the library.  A more frequent case is that a free "
		"library does the same job as widely used non-free libraries.  In this "
		"case, there is little to gain by limiting the free library to free "
		"software only, so we use the Lesser General Public License. "
		"<p>"
		"In other cases, permission to use a particular library in non-free "
		"programs enables a greater number of people to use a large body of "
		"free software.  For example, permission to use the GNU C Library in "
		"non-free programs enables many more people to use the whole GNU "
		"operating system, as well as its variant, the GNU/Linux operating "
		"system. "
		"<p>"
		"Although the Lesser General Public License is Less protective of the "
		"users\' freedom, it does ensure that the user of a program that is "
		"linked with the Library has the freedom and the wherewithal to run "
		"that program using a modified version of the Library. "
		"<p>"
		"The precise terms and conditions for copying, distribution and "
		"modification follow.  Pay close attention to the difference between a "
		"\"work based on the library\" and a \"work that uses the library\".  The "
		"former contains code derived from the library, whereas the latter must "
		"be combined with the library in order to run. "
		"<p>"
		"<h4>GNU LESSER GENERAL PUBLIC LICENSE</h4>"
		"TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION "
		"<p>"
		"0. This License Agreement applies to any software library or other "
		"program which contains a notice placed by the copyright holder or "
		"other authorized party saying it may be distributed under the terms of "
		"this Lesser General Public License (also called \"this License\"). "
		"Each licensee is addressed as \"you\". "
		"<p>"
		"A \"library\" means a collection of software functions and/or data "
		"prepared so as to be conveniently linked with application programs "
		"(which use some of those functions and data) to form executables. "
		"<p>"
		"The \"Library\", below, refers to any such software library or work "
		"which has been distributed under these terms.  A \"work based on the "
		"Library\" means either the Library or any derivative work under "
		"copyright law: that is to say, a work containing the Library or a "
		"portion of it, either verbatim or with modifications and/or translated "
		"straightforwardly into another language.  (Hereinafter, translation is "
		"included without limitation in the term \"modification\".) "
		"<p>"
		"\"Source code\" for a work means the preferred form of the work for "
		"making modifications to it.  For a library, complete source code means "
		"all the source code for all modules it contains, plus any associated "
		"interface definition files, plus the scripts used to control compilation "
		"and installation of the library. "
		"<p>"
		"Activities other than copying, distribution and modification are not "
		"covered by this License; they are outside its scope.  The act of "
		"running a program using the Library is not restricted, and output from "
		"such a program is covered only if its contents constitute a work based "
		"on the Library (independent of the use of the Library in a tool for "
		"writing it).  Whether that is true depends on what the Library does "
		"and what the program that uses the Library does. "
		"<p>"
		"1. You may copy and distribute verbatim copies of the Library\'s "
		"complete source code as you receive it, in any medium, provided that "
		"you conspicuously and appropriately publish on each copy an "
		"appropriate copyright notice and disclaimer of warranty; keep intact "
		"all the notices that refer to this License and to the absence of any "
		"warranty; and distribute a copy of this License along with the "
		"Library. "
		"<p>"
		"You may charge a fee for the physical act of transferring a copy, "
		"and you may at your option offer warranty protection in exchange for a "
		"fee. "
		"<p>"
		"2. You may modify your copy or copies of the Library or any portion "
		"of it, thus forming a work based on the Library, and copy and "
		"distribute such modifications or work under the terms of Section 1 "
		"above, provided that you also meet all of these conditions: "
		"<p>"
		"a) The modified work must itself be a software library. "
		"<p>"
		"b) You must cause the files modified to carry prominent notices "
		"stating that you changed the files and the date of any change. "
		"<p>"
		"c) You must cause the whole of the work to be licensed at no "
		"charge to all third parties under the terms of this License. "
		"<p>"
		"d) If a facility in the modified Library refers to a function or a "
		"table of data to be supplied by an application program that uses "
		"the facility, other than as an argument passed when the facility "
		"is invoked, then you must make a good faith effort to ensure that, "
		"in the event an application does not supply such function or "
		"table, the facility still operates, and performs whatever part of "
		"its purpose remains meaningful. "
		"<p>"
		"(For example, a function in a library to compute square roots has "
		"a purpose that is entirely well-defined independent of the "
		"application.  Therefore, Subsection 2d requires that any "
		"application-supplied function or table used by this function must "
		"be optional: if the application does not supply it, the square "
		"root function must still compute square roots.) "
		"<p>"
		"These requirements apply to the modified work as a whole.  If "
		"identifiable sections of that work are not derived from the Library, "
		"and can be reasonably considered independent and separate works in "
		"themselves, then this License, and its terms, do not apply to those "
		"sections when you distribute them as separate works.  But when you "
		"distribute the same sections as part of a whole which is a work based "
		"on the Library, the distribution of the whole must be on the terms of "
		"this License, whose permissions for other licensees extend to the "
		"entire whole, and thus to each and every part regardless of who wrote "
		"it. "
		"<p>"
		"Thus, it is not the intent of this section to claim rights or contest "
		"your rights to work written entirely by you; rather, the intent is to "
		"exercise the right to control the distribution of derivative or "
		"collective works based on the Library. "
		"<p>"
		"In addition, mere aggregation of another work not based on the Library "
		"with the Library (or with a work based on the Library) on a volume of "
		"a storage or distribution medium does not bring the other work under "
		"the scope of this License. "
		"<p>"
		"3. You may opt to apply the terms of the ordinary GNU General Public "
		"License instead of this License to a given copy of the Library.  To do "
		"this, you must alter all the notices that refer to this License, so "
		"that they refer to the ordinary GNU General Public License, version 2, "
		"instead of to this License.  (If a newer version than version 2 of the "
		"ordinary GNU General Public License has appeared, then you can specify "
		"that version instead if you wish.)  Do not make any other change in "
		"these notices. "
		"<p>"
		"Once this change is made in a given copy, it is irreversible for "
		"that copy, so the ordinary GNU General Public License applies to all "
		"subsequent copies and derivative works made from that copy. "
		"<p>"
		"This option is useful when you wish to copy part of the code of "
		"the Library into a program that is not a library. "
		"<p>"
		"4. You may copy and distribute the Library (or a portion or "
		"derivative of it, under Section 2) in object code or executable form "
		"under the terms of Sections 1 and 2 above provided that you accompany "
		"it with the complete corresponding machine-readable source code, which "
		"must be distributed under the terms of Sections 1 and 2 above on a "
		"medium customarily used for software interchange. "
		"<p>"
		"If distribution of object code is made by offering access to copy "
		"from a designated place, then offering equivalent access to copy the "
		"source code from the same place satisfies the requirement to "
		"distribute the source code, even though third parties are not "
		"compelled to copy the source along with the object code. "
		"<p>"
		"5. A program that contains no derivative of any portion of the "
		"Library, but is designed to work with the Library by being compiled or "
		"linked with it, is called a \"work that uses the Library\".  Such a "
		"work, in isolation, is not a derivative work of the Library, and "
		"therefore falls outside the scope of this License. "
		"<p>"
		"However, linking a \"work that uses the Library\" with the Library "
		"creates an executable that is a derivative of the Library (because it "
		"contains portions of the Library), rather than a \"work that uses the "
		"library\".  The executable is therefore covered by this License. "
		"Section 6 states terms for distribution of such executables. "
		"<p>"
		"When a \"work that uses the Library\" uses material from a header file "
		"that is part of the Library, the object code for the work may be a "
		"derivative work of the Library even though the source code is not. "
		"Whether this is true is especially significant if the work can be "
		"linked without the Library, or if the work is itself a library.  The "
		"threshold for this to be true is not precisely defined by law. "
		"<p>"
		"If such an object file uses only numerical parameters, data "
		"structure layouts and accessors, and small macros and small inline "
		"functions (ten lines or less in length), then the use of the object "
		"file is unrestricted, regardless of whether it is legally a derivative "
		"work.  (Executables containing this object code plus portions of the "
		"Library will still fall under Section 6.) "
		"<p>"
		"Otherwise, if the work is a derivative of the Library, you may "
		"distribute the object code for the work under the terms of Section 6. "
		"Any executables containing that work also fall under Section 6, "
		"whether or not they are linked directly with the Library itself. "
		"<p>"
		"6. As an exception to the Sections above, you may also combine or "
		"link a \"work that uses the Library\" with the Library to produce a "
		"work containing portions of the Library, and distribute that work "
		"under terms of your choice, provided that the terms permit "
		"modification of the work for the customer\'s own use and reverse "
		"engineering for debugging such modifications. "
		"<p>"
		"You must give prominent notice with each copy of the work that the "
		"Library is used in it and that the Library and its use are covered by "
		"this License.  You must supply a copy of this License.  If the work "
		"during execution displays copyright notices, you must include the "
		"copyright notice for the Library among them, as well as a reference "
		"directing the user to the copy of this License.  Also, you must do one "
		"of these things: "
		"<p>"
		"a) Accompany the work with the complete corresponding "
		"machine-readable source code for the Library including whatever "
		"changes were used in the work (which must be distributed under "
		"Sections 1 and 2 above); and, if the work is an executable linked "
		"with the Library, with the complete machine-readable \"work that "
		"uses the Library\", as object code and/or source code, so that the "
		"user can modify the Library and then relink to produce a modified "
		"executable containing the modified Library.  (It is understood "
		"that the user who changes the contents of definitions files in the "
		"Library will not necessarily be able to recompile the application "
		"to use the modified definitions.) "
		"<p>"
		"b) Use a suitable shared library mechanism for linking with the "
		"Library.  A suitable mechanism is one that (1) uses at run time a "
		"copy of the library already present on the user\'s computer system, "
		"rather than copying library functions into the executable, and (2) "
		"will operate properly with a modified version of the library, if "
		"the user installs one, as long as the modified version is "
		"interface-compatible with the version that the work was made with. "
		"<p>"
		"c) Accompany the work with a written offer, valid for at "
		"least three years, to give the same user the materials "
		"specified in Subsection 6a, above, for a charge no more "
		"than the cost of performing this distribution. "
		"<p>"
		"d) If distribution of the work is made by offering access to copy "
		"from a designated place, offer equivalent access to copy the above "
		"specified materials from the same place. "
		"<p>"
		"e) Verify that the user has already received a copy of these "
		"materials or that you have already sent this user a copy. "
		"<p>"
		"For an executable, the required form of the \"work that uses the "
		"Library\" must include any data and utility programs needed for "
		"reproducing the executable from it.  However, as a special exception, "
		"the materials to be distributed need not include anything that is "
		"normally distributed (in either source or binary form) with the major "
		"components (compiler, kernel, and so on) of the operating system on "
		"which the executable runs, unless that component itself accompanies "
		"the executable. "
		"<p>"
		"It may happen that this requirement contradicts the license "
		"restrictions of other proprietary libraries that do not normally "
		"accompany the operating system.  Such a contradiction means you cannot "
		"use both them and the Library together in an executable that you "
		"distribute. "
		"<p>"
		"7. You may place library facilities that are a work based on the "
		"Library side-by-side in a single library together with other library "
		"facilities not covered by this License, and distribute such a combined "
		"library, provided that the separate distribution of the work based on "
		"the Library and of the other library facilities is otherwise "
		"permitted, and provided that you do these two things: "
		"<p>"
		"a) Accompany the combined library with a copy of the same work "
		"based on the Library, uncombined with any other library "
		"facilities.  This must be distributed under the terms of the "
		"Sections above. "
		"<p>"
		"b) Give prominent notice with the combined library of the fact "
		"that part of it is a work based on the Library, and explaining "
		"where to find the accompanying uncombined form of the same work. "
		"<p>"
		"8. You may not copy, modify, sublicense, link with, or distribute "
		"the Library except as expressly provided under this License.  Any "
		"attempt otherwise to copy, modify, sublicense, link with, or "
		"distribute the Library is void, and will automatically terminate your "
		"rights under this License.  However, parties who have received copies, "
		"or rights, from you under this License will not have their licenses "
		"terminated so long as such parties remain in full compliance. "
		"<p>"
		"9. You are not required to accept this License, since you have not "
		"signed it.  However, nothing else grants you permission to modify or "
		"distribute the Library or its derivative works.  These actions are "
		"prohibited by law if you do not accept this License.  Therefore, by "
		"modifying or distributing the Library (or any work based on the "
		"Library), you indicate your acceptance of this License to do so, and "
		"all its terms and conditions for copying, distributing or modifying "
		"the Library or works based on it. "
		"<p>"
		"10. Each time you redistribute the Library (or any work based on the "
		"Library), the recipient automatically receives a license from the "
		"original licensor to copy, distribute, link with or modify the Library "
		"subject to these terms and conditions.  You may not impose any further "
		"restrictions on the recipients\' exercise of the rights granted herein. "
		"You are not responsible for enforcing compliance by third parties with "
		"this License. "
		"<p>"
		"11. If, as a consequence of a court judgment or allegation of patent "
		"infringement or for any other reason (not limited to patent issues), "
		"conditions are imposed on you (whether by court order, agreement or "
		"otherwise) that contradict the conditions of this License, they do not "
		"excuse you from the conditions of this License.  If you cannot "
		"distribute so as to satisfy simultaneously your obligations under this "
		"License and any other pertinent obligations, then as a consequence you "
		"may not distribute the Library at all.  For example, if a patent "
		"license would not permit royalty-free redistribution of the Library by "
		"all those who receive copies directly or indirectly through you, then "
		"the only way you could satisfy both it and this License would be to "
		"refrain entirely from distribution of the Library. "
		"<p>"
		"If any portion of this section is held invalid or unenforceable under any "
		"particular circumstance, the balance of the section is intended to apply, "
		"and the section as a whole is intended to apply in other circumstances. "
		"<p>"
		"It is not the purpose of this section to induce you to infringe any "
		"patents or other property right claims or to contest validity of any "
		"such claims; this section has the sole purpose of protecting the "
		"integrity of the free software distribution system which is "
		"implemented by public license practices.  Many people have made "
		"generous contributions to the wide range of software distributed "
		"through that system in reliance on consistent application of that "
		"system; it is up to the author/donor to decide if he or she is willing "
		"to distribute software through any other system and a licensee cannot "
		"impose that choice. "
		"<p>"
		"This section is intended to make thoroughly clear what is believed to "
		"be a consequence of the rest of this License. "
		"<p>"
		"12. If the distribution and/or use of the Library is restricted in "
		"certain countries either by patents or by copyrighted interfaces, the "
		"original copyright holder who places the Library under this License may add "
		"an explicit geographical distribution limitation excluding those countries, "
		"so that distribution is permitted only in or among countries not thus "
		"excluded.  In such case, this License incorporates the limitation as if "
		"written in the body of this License. "
		"<p>"
		"13. The Free Software Foundation may publish revised and/or new "
		"versions of the Lesser General Public License from time to time. "
		"Such new versions will be similar in spirit to the present version, "
		"but may differ in detail to address new problems or concerns. "
		"<p>"
		"Each version is given a distinguishing version number.  If the Library "
		"specifies a version number of this License which applies to it and "
		"\"any later version\", you have the option of following the terms and "
		"conditions either of that version or of any later version published by "
		"the Free Software Foundation.  If the Library does not specify a "
		"license version number, you may choose any version ever published by "
		"the Free Software Foundation. "
		"<p>"
		"14. If you wish to incorporate parts of the Library into other free "
		"programs whose distribution conditions are incompatible with these, "
		"write to the author to ask for permission.  For software which is "
		"copyrighted by the Free Software Foundation, write to the Free "
		"Software Foundation; we sometimes make exceptions for this.  Our "
		"decision will be guided by the two goals of preserving the free status "
		"of all derivatives of our free software and of promoting the sharing "
		"and reuse of software generally. "
		"<p>"
		"NO WARRANTY "
		"<p>"
		"15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO "
		"WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. "
