1+ GNU LESSER GENERAL PUBLIC LICENSE2+ Version 2.1, February 19993+4+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.5+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA6+ Everyone is permitted to copy and distribute verbatim copies7+ of this license document, but changing it is not allowed.8+9+[This is the first released version of the Lesser GPL. It also counts10+ as the successor of the GNU Library Public License, version 2, hence11+ the version number 2.1.]12+13+ Preamble14+15+ The licenses for most software are designed to take away your16+freedom to share and change it. By contrast, the GNU General Public17+Licenses are intended to guarantee your freedom to share and change18+free software--to make sure the software is free for all its users.19+20+ This license, the Lesser General Public License, applies to some21+specially designated software packages--typically libraries--of the22+Free Software Foundation and other authors who decide to use it. You23+can use it too, but we suggest you first think carefully about whether24+this license or the ordinary General Public License is the better25+strategy to use in any particular case, based on the explanations below.26+27+ When we speak of free software, we are referring to freedom of use,28+not price. Our General Public Licenses are designed to make sure that29+you have the freedom to distribute copies of free software (and charge30+for this service if you wish); that you receive source code or can get31+it if you want it; that you can change the software and use pieces of32+it in new free programs; and that you are informed that you can do33+these things.34+35+ To protect your rights, we need to make restrictions that forbid36+distributors to deny you these rights or to ask you to surrender these37+rights. These restrictions translate to certain responsibilities for38+you if you distribute copies of the library or if you modify it.39+40+ For example, if you distribute copies of the library, whether gratis41+or for a fee, you must give the recipients all the rights that we gave42+you. You must make sure that they, too, receive or can get the source43+code. If you link other code with the library, you must provide44+complete object files to the recipients, so that they can relink them45+with the library after making changes to the library and recompiling46+it. And you must show them these terms so they know their rights.47+48+ We protect your rights with a two-step method: (1) we copyright the49+library, and (2) we offer you this license, which gives you legal50+permission to copy, distribute and/or modify the library.51+52+ To protect each distributor, we want to make it very clear that53+there is no warranty for the free library. Also, if the library is54+modified by someone else and passed on, the recipients should know55+that what they have is not the original version, so that the original56+author's reputation will not be affected by problems that might be57+introduced by others.58+ 59+ Finally, software patents pose a constant threat to the existence of60+any free program. We wish to make sure that a company cannot61+effectively restrict the users of a free program by obtaining a62+restrictive license from a patent holder. Therefore, we insist that63+any patent license obtained for a version of the library must be64+consistent with the full freedom of use specified in this license.65+66+ Most GNU software, including some libraries, is covered by the67+ordinary GNU General Public License. This license, the GNU Lesser68+General Public License, applies to certain designated libraries, and69+is quite different from the ordinary General Public License. We use70+this license for certain libraries in order to permit linking those71+libraries into non-free programs.72+73+ When a program is linked with a library, whether statically or using74+a shared library, the combination of the two is legally speaking a75+combined work, a derivative of the original library. The ordinary76+General Public License therefore permits such linking only if the77+entire combination fits its criteria of freedom. The Lesser General78+Public License permits more lax criteria for linking other code with79+the library.80+81+ We call this license the "Lesser" General Public License because it82+does Less to protect the user's freedom than the ordinary General83+Public License. It also provides other free software developers Less84+of an advantage over competing non-free programs. These disadvantages85+are the reason we use the ordinary General Public License for many86+libraries. However, the Lesser license provides advantages in certain87+special circumstances.88+89+ For example, on rare occasions, there may be a special need to90+encourage the widest possible use of a certain library, so that it becomes91+a de-facto standard. To achieve this, non-free programs must be92+allowed to use the library. A more frequent case is that a free93+library does the same job as widely used non-free libraries. In this94+case, there is little to gain by limiting the free library to free95+software only, so we use the Lesser General Public License.96+97+ In other cases, permission to use a particular library in non-free98+programs enables a greater number of people to use a large body of99+free software. For example, permission to use the GNU C Library in100+non-free programs enables many more people to use the whole GNU101+operating system, as well as its variant, the GNU/Linux operating102+system.103+104+ Although the Lesser General Public License is Less protective of the105+users' freedom, it does ensure that the user of a program that is106+linked with the Library has the freedom and the wherewithal to run107+that program using a modified version of the Library.108+109+ The precise terms and conditions for copying, distribution and110+modification follow. Pay close attention to the difference between a111+"work based on the library" and a "work that uses the library". The112+former contains code derived from the library, whereas the latter must113+be combined with the library in order to run.114+ 115+ GNU LESSER GENERAL PUBLIC LICENSE116+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION117+118+ 0. This License Agreement applies to any software library or other119+program which contains a notice placed by the copyright holder or120+other authorized party saying it may be distributed under the terms of121+this Lesser General Public License (also called "this License").122+Each licensee is addressed as "you".123+124+ A "library" means a collection of software functions and/or data125+prepared so as to be conveniently linked with application programs126+(which use some of those functions and data) to form executables.127+128+ The "Library", below, refers to any such software library or work129+which has been distributed under these terms. A "work based on the130+Library" means either the Library or any derivative work under131+copyright law: that is to say, a work containing the Library or a132+portion of it, either verbatim or with modifications and/or translated133+straightforwardly into another language. (Hereinafter, translation is134+included without limitation in the term "modification".)135+136+ "Source code" for a work means the preferred form of the work for137+making modifications to it. For a library, complete source code means138+all the source code for all modules it contains, plus any associated139+interface definition files, plus the scripts used to control compilation140+and installation of the library.141+142+ Activities other than copying, distribution and modification are not143+covered by this License; they are outside its scope. The act of144+running a program using the Library is not restricted, and output from145+such a program is covered only if its contents constitute a work based146+on the Library (independent of the use of the Library in a tool for147+writing it). Whether that is true depends on what the Library does148+and what the program that uses the Library does.149+ 150+ 1. You may copy and distribute verbatim copies of the Library's151+complete source code as you receive it, in any medium, provided that152+you conspicuously and appropriately publish on each copy an153+appropriate copyright notice and disclaimer of warranty; keep intact154+all the notices that refer to this License and to the absence of any155+warranty; and distribute a copy of this License along with the156+Library.157+158+ You may charge a fee for the physical act of transferring a copy,159+and you may at your option offer warranty protection in exchange for a160+fee.161+ 162+ 2. You may modify your copy or copies of the Library or any portion163+of it, thus forming a work based on the Library, and copy and164+distribute such modifications or work under the terms of Section 1165+above, provided that you also meet all of these conditions:166+167+ a) The modified work must itself be a software library.168+169+ b) You must cause the files modified to carry prominent notices170+ stating that you changed the files and the date of any change.171+172+ c) You must cause the whole of the work to be licensed at no173+ charge to all third parties under the terms of this License.174+175+ d) If a facility in the modified Library refers to a function or a176+ table of data to be supplied by an application program that uses177+ the facility, other than as an argument passed when the facility178+ is invoked, then you must make a good faith effort to ensure that,179+ in the event an application does not supply such function or180+ table, the facility still operates, and performs whatever part of181+ its purpose remains meaningful.182+183+ (For example, a function in a library to compute square roots has184+ a purpose that is entirely well-defined independent of the185+ application. Therefore, Subsection 2d requires that any186+ application-supplied function or table used by this function must187+ be optional: if the application does not supply it, the square188+ root function must still compute square roots.)189+190+These requirements apply to the modified work as a whole. If191+identifiable sections of that work are not derived from the Library,192+and can be reasonably considered independent and separate works in193+themselves, then this License, and its terms, do not apply to those194+sections when you distribute them as separate works. But when you195+distribute the same sections as part of a whole which is a work based196+on the Library, the distribution of the whole must be on the terms of197+this License, whose permissions for other licensees extend to the198+entire whole, and thus to each and every part regardless of who wrote199+it.200+201+Thus, it is not the intent of this section to claim rights or contest202+your rights to work written entirely by you; rather, the intent is to203+exercise the right to control the distribution of derivative or204+collective works based on the Library.205+206+In addition, mere aggregation of another work not based on the Library207+with the Library (or with a work based on the Library) on a volume of208+a storage or distribution medium does not bring the other work under209+the scope of this License.210+211+ 3. You may opt to apply the terms of the ordinary GNU General Public212+License instead of this License to a given copy of the Library. To do213+this, you must alter all the notices that refer to this License, so214+that they refer to the ordinary GNU General Public License, version 2,215+instead of to this License. (If a newer version than version 2 of the216+ordinary GNU General Public License has appeared, then you can specify217+that version instead if you wish.) Do not make any other change in218+these notices.219+ 220+ Once this change is made in a given copy, it is irreversible for221+that copy, so the ordinary GNU General Public License applies to all222+subsequent copies and derivative works made from that copy.223+224+ This option is useful when you wish to copy part of the code of225+the Library into a program that is not a library.226+227+ 4. You may copy and distribute the Library (or a portion or228+derivative of it, under Section 2) in object code or executable form229+under the terms of Sections 1 and 2 above provided that you accompany230+it with the complete corresponding machine-readable source code, which231+must be distributed under the terms of Sections 1 and 2 above on a232+medium customarily used for software interchange.233+234+ If distribution of object code is made by offering access to copy235+from a designated place, then offering equivalent access to copy the236+source code from the same place satisfies the requirement to237+distribute the source code, even though third parties are not238+compelled to copy the source along with the object code.239+240+ 5. A program that contains no derivative of any portion of the241+Library, but is designed to work with the Library by being compiled or242+linked with it, is called a "work that uses the Library". Such a243+work, in isolation, is not a derivative work of the Library, and244+therefore falls outside the scope of this License.245+246+ However, linking a "work that uses the Library" with the Library247+creates an executable that is a derivative of the Library (because it248+contains portions of the Library), rather than a "work that uses the249+library". The executable is therefore covered by this License.250+Section 6 states terms for distribution of such executables.251+252+ When a "work that uses the Library" uses material from a header file253+that is part of the Library, the object code for the work may be a254+derivative work of the Library even though the source code is not.255+Whether this is true is especially significant if the work can be256+linked without the Library, or if the work is itself a library. The257+threshold for this to be true is not precisely defined by law.258+259+ If such an object file uses only numerical parameters, data260+structure layouts and accessors, and small macros and small inline261+functions (ten lines or less in length), then the use of the object262+file is unrestricted, regardless of whether it is legally a derivative263+work. (Executables containing this object code plus portions of the264+Library will still fall under Section 6.)265+266+ Otherwise, if the work is a derivative of the Library, you may267+distribute the object code for the work under the terms of Section 6.268+Any executables containing that work also fall under Section 6,269+whether or not they are linked directly with the Library itself.270+ 271+ 6. As an exception to the Sections above, you may also combine or272+link a "work that uses the Library" with the Library to produce a273+work containing portions of the Library, and distribute that work274+under terms of your choice, provided that the terms permit275+modification of the work for the customer's own use and reverse276+engineering for debugging such modifications.277+278+ You must give prominent notice with each copy of the work that the279+Library is used in it and that the Library and its use are covered by280+this License. You must supply a copy of this License. If the work281+during execution displays copyright notices, you must include the282+copyright notice for the Library among them, as well as a reference283+directing the user to the copy of this License. Also, you must do one284+of these things:285+286+ a) Accompany the work with the complete corresponding287+ machine-readable source code for the Library including whatever288+ changes were used in the work (which must be distributed under289+ Sections 1 and 2 above); and, if the work is an executable linked290+ with the Library, with the complete machine-readable "work that291+ uses the Library", as object code and/or source code, so that the292+ user can modify the Library and then relink to produce a modified293+ executable containing the modified Library. (It is understood294+ that the user who changes the contents of definitions files in the295+ Library will not necessarily be able to recompile the application296+ to use the modified definitions.)297+298+ b) Use a suitable shared library mechanism for linking with the299+ Library. A suitable mechanism is one that (1) uses at run time a300+ copy of the library already present on the user's computer system,301+ rather than copying library functions into the executable, and (2)302+ will operate properly with a modified version of the library, if303+ the user installs one, as long as the modified version is304+ interface-compatible with the version that the work was made with.305+306+ c) Accompany the work with a written offer, valid for at307+ least three years, to give the same user the materials308+ specified in Subsection 6a, above, for a charge no more309+ than the cost of performing this distribution.310+311+ d) If distribution of the work is made by offering access to copy312+ from a designated place, offer equivalent access to copy the above313+ specified materials from the same place.314+315+ e) Verify that the user has already received a copy of these316+ materials or that you have already sent this user a copy.317+318+ For an executable, the required form of the "work that uses the319+Library" must include any data and utility programs needed for320+reproducing the executable from it. However, as a special exception,321+the materials to be distributed need not include anything that is322+normally distributed (in either source or binary form) with the major323+components (compiler, kernel, and so on) of the operating system on324+which the executable runs, unless that component itself accompanies325+the executable.326+327+ It may happen that this requirement contradicts the license328+restrictions of other proprietary libraries that do not normally329+accompany the operating system. Such a contradiction means you cannot330+use both them and the Library together in an executable that you331+distribute.332+ 333+ 7. You may place library facilities that are a work based on the334+Library side-by-side in a single library together with other library335+facilities not covered by this License, and distribute such a combined336+library, provided that the separate distribution of the work based on337+the Library and of the other library facilities is otherwise338+permitted, and provided that you do these two things:339+340+ a) Accompany the combined library with a copy of the same work341+ based on the Library, uncombined with any other library342+ facilities. This must be distributed under the terms of the343+ Sections above.344+345+ b) Give prominent notice with the combined library of the fact346+ that part of it is a work based on the Library, and explaining347+ where to find the accompanying uncombined form of the same work.348+349+ 8. You may not copy, modify, sublicense, link with, or distribute350+the Library except as expressly provided under this License. Any351+attempt otherwise to copy, modify, sublicense, link with, or352+distribute the Library is void, and will automatically terminate your353+rights under this License. However, parties who have received copies,354+or rights, from you under this License will not have their licenses355+terminated so long as such parties remain in full compliance.356+357+ 9. You are not required to accept this License, since you have not358+signed it. However, nothing else grants you permission to modify or359+distribute the Library or its derivative works. These actions are360+prohibited by law if you do not accept this License. Therefore, by361+modifying or distributing the Library (or any work based on the362+Library), you indicate your acceptance of this License to do so, and363+all its terms and conditions for copying, distributing or modifying364+the Library or works based on it.365+366+ 10. Each time you redistribute the Library (or any work based on the367+Library), the recipient automatically receives a license from the368+original licensor to copy, distribute, link with or modify the Library369+subject to these terms and conditions. You may not impose any further370+restrictions on the recipients' exercise of the rights granted herein.371+You are not responsible for enforcing compliance by third parties with372+this License.373+ 374+ 11. If, as a consequence of a court judgment or allegation of patent375+infringement or for any other reason (not limited to patent issues),376+conditions are imposed on you (whether by court order, agreement or377+otherwise) that contradict the conditions of this License, they do not378+excuse you from the conditions of this License. If you cannot379+distribute so as to satisfy simultaneously your obligations under this380+License and any other pertinent obligations, then as a consequence you381+may not distribute the Library at all. For example, if a patent382+license would not permit royalty-free redistribution of the Library by383+all those who receive copies directly or indirectly through you, then384+the only way you could satisfy both it and this License would be to385+refrain entirely from distribution of the Library.386+387+If any portion of this section is held invalid or unenforceable under any388+particular circumstance, the balance of the section is intended to apply,389+and the section as a whole is intended to apply in other circumstances.390+391+It is not the purpose of this section to induce you to infringe any392+patents or other property right claims or to contest validity of any393+such claims; this section has the sole purpose of protecting the394+integrity of the free software distribution system which is395+implemented by public license practices. Many people have made396+generous contributions to the wide range of software distributed397+through that system in reliance on consistent application of that398+system; it is up to the author/donor to decide if he or she is willing399+to distribute software through any other system and a licensee cannot400+impose that choice.401+402+This section is intended to make thoroughly clear what is believed to403+be a consequence of the rest of this License.404+405+ 12. If the distribution and/or use of the Library is restricted in406+certain countries either by patents or by copyrighted interfaces, the407+original copyright holder who places the Library under this License may add408+an explicit geographical distribution limitation excluding those countries,409+so that distribution is permitted only in or among countries not thus410+excluded. In such case, this License incorporates the limitation as if411+written in the body of this License.412+413+ 13. The Free Software Foundation may publish revised and/or new414+versions of the Lesser General Public License from time to time.415+Such new versions will be similar in spirit to the present version,416+but may differ in detail to address new problems or concerns.417+418+Each version is given a distinguishing version number. If the Library419+specifies a version number of this License which applies to it and420+"any later version", you have the option of following the terms and421+conditions either of that version or of any later version published by422+the Free Software Foundation. If the Library does not specify a423+license version number, you may choose any version ever published by424+the Free Software Foundation.425+ 426+ 14. If you wish to incorporate parts of the Library into other free427+programs whose distribution conditions are incompatible with these,428+write to the author to ask for permission. For software which is429+copyrighted by the Free Software Foundation, write to the Free430+Software Foundation; we sometimes make exceptions for this. Our431+decision will be guided by the two goals of preserving the free status432+of all derivatives of our free software and of promoting the sharing433+and reuse of software generally.434+435+ NO WARRANTY436+437+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO438+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.439+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR440+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY441+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE442+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR443+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE444+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME445+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.446+447+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN448+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY449+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU450+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR451+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE452+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING453+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A454+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF455+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH456+DAMAGES.457+458+ END OF TERMS AND CONDITIONS@@ -0,0 +1,27 @@
