- GNU LESSER GENERAL PUBLIC LICENSE\r
- Version 2.1, February 1999\r
-\r
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.\r
- 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA\r
- Everyone is permitted to copy and distribute verbatim copies\r
- of this license document, but changing it is not allowed.\r
-\r
-[This is the first released version of the Lesser GPL. It also counts\r
- as the successor of the GNU Library Public License, version 2, hence\r
- the version number 2.1.]\r
-\r
- Preamble\r
-\r
- The licenses for most software are designed to take away your\r
-freedom to share and change it. By contrast, the GNU General Public\r
-Licenses are intended to guarantee your freedom to share and change\r
-free software--to make sure the software is free for all its users.\r
-\r
- This license, the Lesser General Public License, applies to some\r
-specially designated software packages--typically libraries--of the\r
-Free Software Foundation and other authors who decide to use it. You\r
-can use it too, but we suggest you first think carefully about whether\r
-this license or the ordinary General Public License is the better\r
-strategy to use in any particular case, based on the explanations below.\r
-\r
- When we speak of free software, we are referring to freedom of use,\r
-not price. Our General Public Licenses are designed to make sure that\r
-you have the freedom to distribute copies of free software (and charge\r
-for this service if you wish); that you receive source code or can get\r
-it if you want it; that you can change the software and use pieces of\r
-it in new free programs; and that you are informed that you can do\r
-these things.\r
-\r
- To protect your rights, we need to make restrictions that forbid\r
-distributors to deny you these rights or to ask you to surrender these\r
-rights. These restrictions translate to certain responsibilities for\r
-you if you distribute copies of the library or if you modify it.\r
-\r
- For example, if you distribute copies of the library, whether gratis\r
-or for a fee, you must give the recipients all the rights that we gave\r
-you. You must make sure that they, too, receive or can get the source\r
-code. If you link other code with the library, you must provide\r
-complete object files to the recipients, so that they can relink them\r
-with the library after making changes to the library and recompiling\r
-it. And you must show them these terms so they know their rights.\r
-\r
- We protect your rights with a two-step method: (1) we copyright the\r
-library, and (2) we offer you this license, which gives you legal\r
-permission to copy, distribute and/or modify the library.\r
-\r
- To protect each distributor, we want to make it very clear that\r
-there is no warranty for the free library. Also, if the library is\r
-modified by someone else and passed on, the recipients should know\r
-that what they have is not the original version, so that the original\r
-author's reputation will not be affected by problems that might be\r
-introduced by others.\r
-\f\r
- Finally, software patents pose a constant threat to the existence of\r
-any free program. We wish to make sure that a company cannot\r
-effectively restrict the users of a free program by obtaining a\r
-restrictive license from a patent holder. Therefore, we insist that\r
-any patent license obtained for a version of the library must be\r
-consistent with the full freedom of use specified in this license.\r
-\r
- Most GNU software, including some libraries, is covered by the\r
-ordinary GNU General Public License. This license, the GNU Lesser\r
-General Public License, applies to certain designated libraries, and\r
-is quite different from the ordinary General Public License. We use\r
-this license for certain libraries in order to permit linking those\r
-libraries into non-free programs.\r
-\r
- When a program is linked with a library, whether statically or using\r
-a shared library, the combination of the two is legally speaking a\r
-combined work, a derivative of the original library. The ordinary\r
-General Public License therefore permits such linking only if the\r
-entire combination fits its criteria of freedom. The Lesser General\r
-Public License permits more lax criteria for linking other code with\r
-the library.\r
-\r
- We call this license the "Lesser" General Public License because it\r
-does Less to protect the user's freedom than the ordinary General\r
-Public License. It also provides other free software developers Less\r
-of an advantage over competing non-free programs. These disadvantages\r
-are the reason we use the ordinary General Public License for many\r
-libraries. However, the Lesser license provides advantages in certain\r
-special circumstances.\r
-\r
- For example, on rare occasions, there may be a special need to\r
-encourage the widest possible use of a certain library, so that it becomes\r
-a de-facto standard. To achieve this, non-free programs must be\r
-allowed to use the library. A more frequent case is that a free\r
-library does the same job as widely used non-free libraries. In this\r
-case, there is little to gain by limiting the free library to free\r
-software only, so we use the Lesser General Public License.\r
-\r
- In other cases, permission to use a particular library in non-free\r
-programs enables a greater number of people to use a large body of\r
-free software. For example, permission to use the GNU C Library in\r
-non-free programs enables many more people to use the whole GNU\r
-operating system, as well as its variant, the GNU/Linux operating\r
-system.\r
-\r
- Although the Lesser General Public License is Less protective of the\r
-users' freedom, it does ensure that the user of a program that is\r
-linked with the Library has the freedom and the wherewithal to run\r
-that program using a modified version of the Library.\r
-\r
- The precise terms and conditions for copying, distribution and\r
-modification follow. Pay close attention to the difference between a\r
-"work based on the library" and a "work that uses the library". The\r
-former contains code derived from the library, whereas the latter must\r
-be combined with the library in order to run.\r
-\f\r
- GNU LESSER GENERAL PUBLIC LICENSE\r
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\r
-\r
- 0. This License Agreement applies to any software library or other\r
-program which contains a notice placed by the copyright holder or\r
-other authorized party saying it may be distributed under the terms of\r
-this Lesser General Public License (also called "this License").\r
-Each licensee is addressed as "you".\r
-\r
- A "library" means a collection of software functions and/or data\r
-prepared so as to be conveniently linked with application programs\r
-(which use some of those functions and data) to form executables.\r
-\r
- The "Library", below, refers to any such software library or work\r
-which has been distributed under these terms. A "work based on the\r
-Library" means either the Library or any derivative work under\r
-copyright law: that is to say, a work containing the Library or a\r
-portion of it, either verbatim or with modifications and/or translated\r
-straightforwardly into another language. (Hereinafter, translation is\r
-included without limitation in the term "modification".)\r
-\r
- "Source code" for a work means the preferred form of the work for\r
-making modifications to it. For a library, complete source code means\r
-all the source code for all modules it contains, plus any associated\r
-interface definition files, plus the scripts used to control compilation\r
-and installation of the library.\r
-\r
- Activities other than copying, distribution and modification are not\r
-covered by this License; they are outside its scope. The act of\r
-running a program using the Library is not restricted, and output from\r
-such a program is covered only if its contents constitute a work based\r
-on the Library (independent of the use of the Library in a tool for\r
-writing it). Whether that is true depends on what the Library does\r
-and what the program that uses the Library does.\r
- \r
- 1. You may copy and distribute verbatim copies of the Library's\r
-complete source code as you receive it, in any medium, provided that\r
-you conspicuously and appropriately publish on each copy an\r
-appropriate copyright notice and disclaimer of warranty; keep intact\r
-all the notices that refer to this License and to the absence of any\r
-warranty; and distribute a copy of this License along with the\r
-Library.\r
-\r
- You may charge a fee for the physical act of transferring a copy,\r
-and you may at your option offer warranty protection in exchange for a\r
-fee.\r
-\f\r
- 2. You may modify your copy or copies of the Library or any portion\r
-of it, thus forming a work based on the Library, and copy and\r
-distribute such modifications or work under the terms of Section 1\r
-above, provided that you also meet all of these conditions:\r
-\r
- a) The modified work must itself be a software library.\r
-\r
- b) You must cause the files modified to carry prominent notices\r
- stating that you changed the files and the date of any change.\r
-\r
- c) You must cause the whole of the work to be licensed at no\r
- charge to all third parties under the terms of this License.\r
-\r
- d) If a facility in the modified Library refers to a function or a\r
- table of data to be supplied by an application program that uses\r
- the facility, other than as an argument passed when the facility\r
- is invoked, then you must make a good faith effort to ensure that,\r
- in the event an application does not supply such function or\r
- table, the facility still operates, and performs whatever part of\r
- its purpose remains meaningful.\r
-\r
- (For example, a function in a library to compute square roots has\r
- a purpose that is entirely well-defined independent of the\r
- application. Therefore, Subsection 2d requires that any\r
- application-supplied function or table used by this function must\r
- be optional: if the application does not supply it, the square\r
- root function must still compute square roots.)\r
-\r
-These requirements apply to the modified work as a whole. If\r
-identifiable sections of that work are not derived from the Library,\r
-and can be reasonably considered independent and separate works in\r
-themselves, then this License, and its terms, do not apply to those\r
-sections when you distribute them as separate works. But when you\r
-distribute the same sections as part of a whole which is a work based\r
-on the Library, the distribution of the whole must be on the terms of\r
-this License, whose permissions for other licensees extend to the\r
-entire whole, and thus to each and every part regardless of who wrote\r
-it.\r
-\r
-Thus, it is not the intent of this section to claim rights or contest\r
-your rights to work written entirely by you; rather, the intent is to\r
-exercise the right to control the distribution of derivative or\r
-collective works based on the Library.\r
-\r
-In addition, mere aggregation of another work not based on the Library\r
-with the Library (or with a work based on the Library) on a volume of\r
-a storage or distribution medium does not bring the other work under\r
-the scope of this License.\r
-\r
- 3. You may opt to apply the terms of the ordinary GNU General Public\r
-License instead of this License to a given copy of the Library. To do\r
-this, you must alter all the notices that refer to this License, so\r
-that they refer to the ordinary GNU General Public License, version 2,\r
-instead of to this License. (If a newer version than version 2 of the\r
-ordinary GNU General Public License has appeared, then you can specify\r
-that version instead if you wish.) Do not make any other change in\r
-these notices.\r
-\f\r
- Once this change is made in a given copy, it is irreversible for\r
-that copy, so the ordinary GNU General Public License applies to all\r
-subsequent copies and derivative works made from that copy.\r
-\r
- This option is useful when you wish to copy part of the code of\r
-the Library into a program that is not a library.\r
-\r
- 4. You may copy and distribute the Library (or a portion or\r
-derivative of it, under Section 2) in object code or executable form\r
-under the terms of Sections 1 and 2 above provided that you accompany\r
-it with the complete corresponding machine-readable source code, which\r
-must be distributed under the terms of Sections 1 and 2 above on a\r
-medium customarily used for software interchange.\r
-\r
- If distribution of object code is made by offering access to copy\r
-from a designated place, then offering equivalent access to copy the\r
-source code from the same place satisfies the requirement to\r
-distribute the source code, even though third parties are not\r
-compelled to copy the source along with the object code.\r
-\r
- 5. A program that contains no derivative of any portion of the\r
-Library, but is designed to work with the Library by being compiled or\r
-linked with it, is called a "work that uses the Library". Such a\r
-work, in isolation, is not a derivative work of the Library, and\r
-therefore falls outside the scope of this License.\r
-\r
- However, linking a "work that uses the Library" with the Library\r
-creates an executable that is a derivative of the Library (because it\r
-contains portions of the Library), rather than a "work that uses the\r
-library". The executable is therefore covered by this License.\r
-Section 6 states terms for distribution of such executables.\r
-\r
- When a "work that uses the Library" uses material from a header file\r
-that is part of the Library, the object code for the work may be a\r
-derivative work of the Library even though the source code is not.\r
-Whether this is true is especially significant if the work can be\r
-linked without the Library, or if the work is itself a library. The\r
-threshold for this to be true is not precisely defined by law.\r
-\r
- If such an object file uses only numerical parameters, data\r
-structure layouts and accessors, and small macros and small inline\r
-functions (ten lines or less in length), then the use of the object\r
-file is unrestricted, regardless of whether it is legally a derivative\r
-work. (Executables containing this object code plus portions of the\r
-Library will still fall under Section 6.)\r
-\r
- Otherwise, if the work is a derivative of the Library, you may\r
-distribute the object code for the work under the terms of Section 6.\r
-Any executables containing that work also fall under Section 6,\r
-whether or not they are linked directly with the Library itself.\r
-\f\r
- 6. As an exception to the Sections above, you may also combine or\r
-link a "work that uses the Library" with the Library to produce a\r
-work containing portions of the Library, and distribute that work\r
-under terms of your choice, provided that the terms permit\r
-modification of the work for the customer's own use and reverse\r
-engineering for debugging such modifications.\r
-\r
- You must give prominent notice with each copy of the work that the\r
-Library is used in it and that the Library and its use are covered by\r
-this License. You must supply a copy of this License. If the work\r
-during execution displays copyright notices, you must include the\r
-copyright notice for the Library among them, as well as a reference\r
-directing the user to the copy of this License. Also, you must do one\r
-of these things:\r
-\r
- a) Accompany the work with the complete corresponding\r
- machine-readable source code for the Library including whatever\r
- changes were used in the work (which must be distributed under\r
- Sections 1 and 2 above); and, if the work is an executable linked\r
- with the Library, with the complete machine-readable "work that\r
- uses the Library", as object code and/or source code, so that the\r
- user can modify the Library and then relink to produce a modified\r
- executable containing the modified Library. (It is understood\r
- that the user who changes the contents of definitions files in the\r
- Library will not necessarily be able to recompile the application\r
- to use the modified definitions.)\r
-\r
- b) Use a suitable shared library mechanism for linking with the\r
- Library. A suitable mechanism is one that (1) uses at run time a\r
- copy of the library already present on the user's computer system,\r
- rather than copying library functions into the executable, and (2)\r
- will operate properly with a modified version of the library, if\r
- the user installs one, as long as the modified version is\r
- interface-compatible with the version that the work was made with.\r
-\r
- c) Accompany the work with a written offer, valid for at\r
- least three years, to give the same user the materials\r
- specified in Subsection 6a, above, for a charge no more\r
- than the cost of performing this distribution.\r
-\r
- d) If distribution of the work is made by offering access to copy\r
- from a designated place, offer equivalent access to copy the above\r
- specified materials from the same place.\r
-\r
- e) Verify that the user has already received a copy of these\r
- materials or that you have already sent this user a copy.\r
-\r
- For an executable, the required form of the "work that uses the\r
-Library" must include any data and utility programs needed for\r
-reproducing the executable from it. However, as a special exception,\r
-the materials to be distributed need not include anything that is\r
-normally distributed (in either source or binary form) with the major\r
-components (compiler, kernel, and so on) of the operating system on\r
-which the executable runs, unless that component itself accompanies\r
-the executable.\r
-\r
- It may happen that this requirement contradicts the license\r
-restrictions of other proprietary libraries that do not normally\r
-accompany the operating system. Such a contradiction means you cannot\r
-use both them and the Library together in an executable that you\r
-distribute.\r
-\f\r
- 7. You may place library facilities that are a work based on the\r
-Library side-by-side in a single library together with other library\r
-facilities not covered by this License, and distribute such a combined\r
-library, provided that the separate distribution of the work based on\r
-the Library and of the other library facilities is otherwise\r
-permitted, and provided that you do these two things:\r
-\r
- a) Accompany the combined library with a copy of the same work\r
- based on the Library, uncombined with any other library\r
- facilities. This must be distributed under the terms of the\r
- Sections above.\r
-\r
- b) Give prominent notice with the combined library of the fact\r
- that part of it is a work based on the Library, and explaining\r
- where to find the accompanying uncombined form of the same work.\r
-\r
- 8. You may not copy, modify, sublicense, link with, or distribute\r
-the Library except as expressly provided under this License. Any\r
-attempt otherwise to copy, modify, sublicense, link with, or\r
-distribute the Library is void, and will automatically terminate your\r
-rights under this License. However, parties who have received copies,\r
-or rights, from you under this License will not have their licenses\r
-terminated so long as such parties remain in full compliance.\r
-\r
- 9. You are not required to accept this License, since you have not\r
-signed it. However, nothing else grants you permission to modify or\r
-distribute the Library or its derivative works. These actions are\r
-prohibited by law if you do not accept this License. Therefore, by\r
-modifying or distributing the Library (or any work based on the\r
-Library), you indicate your acceptance of this License to do so, and\r
-all its terms and conditions for copying, distributing or modifying\r
-the Library or works based on it.\r
-\r
- 10. Each time you redistribute the Library (or any work based on the\r
-Library), the recipient automatically receives a license from the\r
-original licensor to copy, distribute, link with or modify the Library\r
-subject to these terms and conditions. You may not impose any further\r
-restrictions on the recipients' exercise of the rights granted herein.\r
-You are not responsible for enforcing compliance by third parties with\r
-this License.\r
-\f\r
- 11. If, as a consequence of a court judgment or allegation of patent\r
-infringement or for any other reason (not limited to patent issues),\r
-conditions are imposed on you (whether by court order, agreement or\r
-otherwise) that contradict the conditions of this License, they do not\r
-excuse you from the conditions of this License. If you cannot\r
-distribute so as to satisfy simultaneously your obligations under this\r
-License and any other pertinent obligations, then as a consequence you\r
-may not distribute the Library at all. For example, if a patent\r
-license would not permit royalty-free redistribution of the Library by\r
-all those who receive copies directly or indirectly through you, then\r
-the only way you could satisfy both it and this License would be to\r
-refrain entirely from distribution of the Library.\r
-\r
-If any portion of this section is held invalid or unenforceable under any\r
-particular circumstance, the balance of the section is intended to apply,\r
-and the section as a whole is intended to apply in other circumstances.\r
-\r
-It is not the purpose of this section to induce you to infringe any\r
-patents or other property right claims or to contest validity of any\r
-such claims; this section has the sole purpose of protecting the\r
-integrity of the free software distribution system which is\r
-implemented by public license practices. Many people have made\r
-generous contributions to the wide range of software distributed\r
-through that system in reliance on consistent application of that\r
-system; it is up to the author/donor to decide if he or she is willing\r
-to distribute software through any other system and a licensee cannot\r
-impose that choice.\r
-\r
-This section is intended to make thoroughly clear what is believed to\r
-be a consequence of the rest of this License.\r
-\r

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[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.]
+
+ Preamble
+
+ 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.
+
+ 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.
+
+ 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.
+
+ 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.
+
+ 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.
+
+ 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.
+
+ 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.
+\f
+ 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.
+
+ 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.
+
+ 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.
+
+ 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.
+
+ 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.
+
+ 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.
+
+ 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.
+
+ 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.
+\f
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 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".
+
+ 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.
+
+ 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".)
+
+ "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.
+
+ 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.
+
+ 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.
+
+ 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.
+\f
+ 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:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ 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.
+
+ 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.
+
+ (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.)
+
+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.
+
+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.
+
+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.
+
+ 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.
+\f
+ 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.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 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.
+
+ 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.
+
+ 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.
+
+ 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.
+
+ 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.
+
+ 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.)
+
+ 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.
+\f
+ 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.
+
+ 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:
+
+ 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.)
+
+ 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.
+
+ 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.
+
+ 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.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ 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.
+
+ 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.
+\f
+ 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:
+
+ 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.
+
+ 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.
+
+ 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.
+
+ 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.
+
+ 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.
+\f
+ 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.
+
+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.
+
+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.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 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.
+
+ 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.
+
+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.
+\f
+ 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.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+\f
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
