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.++  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.++  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.++  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.++  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.++  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.++  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.++  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.++  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++           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.++    <one line to give the library's name and a brief idea of what it does.>+    Copyright (C) <year>  <name of author>++    This library is free software; you can redistribute it and/or+    modify it under the terms of the GNU Lesser General Public+    License as published by the Free Software Foundation; either+    version 2.1 of the License, or (at your option) any later version.++    This library is distributed in the hope that it will be useful,+    but WITHOUT ANY WARRANTY; without even the implied warranty of+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
