										    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. |

 |

								 | 
							
							  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 |
