It also counts 10*92a65355Syangbill as the successor of the GNU Library Public License, version 2, hence 11*92a65355Syangbill the version number 2.1.] 12*92a65355Syangbill 13*92a65355Syangbill Preamble 14*92a65355Syangbill 15*92a65355Syangbill The licenses for most software are designed to take away your 16*92a65355Syangbillfreedom to share and change it. By contrast, the GNU General Public 17*92a65355SyangbillLicenses are intended to guarantee your freedom to share and change 18*92a65355Syangbillfree software--to make sure the software is free for all its users. 19*92a65355Syangbill 20*92a65355Syangbill This license, the Lesser General Public License, applies to some 21*92a65355Syangbillspecially designated software packages--typically libraries--of the 22*92a65355SyangbillFree Software Foundation and other authors who decide to use it. You 23*92a65355Syangbillcan use it too, but we suggest you first think carefully about whether 24*92a65355Syangbillthis license or the ordinary General Public License is the better 25*92a65355Syangbillstrategy to use in any particular case, based on the explanations below. 26*92a65355Syangbill 27*92a65355Syangbill When we speak of free software, we are referring to freedom of use, 28*92a65355Syangbillnot price. Our General Public Licenses are designed to make sure that 29*92a65355Syangbillyou have the freedom to distribute copies of free software (and charge 30*92a65355Syangbillfor this service if you wish); that you receive source code or can get 31*92a65355Syangbillit if you want it; that you can change the software and use pieces of 32*92a65355Syangbillit in new free programs; and that you are informed that you can do 33*92a65355Syangbillthese things. 34*92a65355Syangbill 35*92a65355Syangbill To protect your rights, we need to make restrictions that forbid 36*92a65355Syangbilldistributors to deny you these rights or to ask you to surrender these 37*92a65355Syangbillrights. These restrictions translate to certain responsibilities for 38*92a65355Syangbillyou if you distribute copies of the library or if you modify it. 39*92a65355Syangbill 40*92a65355Syangbill For example, if you distribute copies of the library, whether gratis 41*92a65355Syangbillor for a fee, you must give the recipients all the rights that we gave 42*92a65355Syangbillyou. You must make sure that they, too, receive or can get the source 43*92a65355Syangbillcode. If you link other code with the library, you must provide 44*92a65355Syangbillcomplete object files to the recipients, so that they can relink them 45*92a65355Syangbillwith the library after making changes to the library and recompiling 46*92a65355Syangbillit. And you must show them these terms so they know their rights. 47*92a65355Syangbill 48*92a65355Syangbill We protect your rights with a two-step method: (1) we copyright the 49*92a65355Syangbilllibrary, and (2) we offer you this license, which gives you legal 50*92a65355Syangbillpermission to copy, distribute and/or modify the library. 51*92a65355Syangbill 52*92a65355Syangbill To protect each distributor, we want to make it very clear that 53*92a65355Syangbillthere is no warranty for the free library. Also, if the library is 54*92a65355Syangbillmodified by someone else and passed on, the recipients should know 55*92a65355Syangbillthat what they have is not the original version, so that the original 56*92a65355Syangbillauthor's reputation will not be affected by problems that might be 57*92a65355Syangbillintroduced by others. 58*92a65355Syangbill 59*92a65355Syangbill Finally, software patents pose a constant threat to the existence of 60*92a65355Syangbillany free program. We wish to make sure that a company cannot 61*92a65355Syangbilleffectively restrict the users of a free program by obtaining a 62*92a65355Syangbillrestrictive license from a patent holder. Therefore, we insist that 63*92a65355Syangbillany patent license obtained for a version of the library must be 64*92a65355Syangbillconsistent with the full freedom of use specified in this license. 65*92a65355Syangbill 66*92a65355Syangbill Most GNU software, including some libraries, is covered by the 67*92a65355Syangbillordinary GNU General Public License. This license, the GNU Lesser 68*92a65355SyangbillGeneral Public License, applies to certain designated libraries, and 69*92a65355Syangbillis quite different from the ordinary General Public License. We use 70*92a65355Syangbillthis license for certain libraries in order to permit linking those 71*92a65355Syangbilllibraries into non-free programs. 72*92a65355Syangbill 73*92a65355Syangbill When a program is linked with a library, whether statically or using 74*92a65355Syangbilla shared library, the combination of the two is legally speaking a 75*92a65355Syangbillcombined work, a derivative of the original library. The ordinary 76*92a65355SyangbillGeneral Public License therefore permits such linking only if the 77*92a65355Syangbillentire combination fits its criteria of freedom. The Lesser General 78*92a65355SyangbillPublic License permits more lax criteria for linking other code with 79*92a65355Syangbillthe library. 80*92a65355Syangbill 81*92a65355Syangbill We call this license the "Lesser" General Public License because it 82*92a65355Syangbilldoes Less to protect the user's freedom than the ordinary General 83*92a65355SyangbillPublic License. It also provides other free software developers Less 84*92a65355Syangbillof an advantage over competing non-free programs. These disadvantages 85*92a65355Syangbillare the reason we use the ordinary General Public License for many 86*92a65355Syangbilllibraries. However, the Lesser license provides advantages in certain 87*92a65355Syangbillspecial circumstances. 88*92a65355Syangbill 89*92a65355Syangbill For example, on rare occasions, there may be a special need to 90*92a65355Syangbillencourage the widest possible use of a certain library, so that it becomes 91*92a65355Syangbilla de-facto standard. To achieve this, non-free programs must be 92*92a65355Syangbillallowed to use the library. A more frequent case is that a free 93*92a65355Syangbilllibrary does the same job as widely used non-free libraries. In this 94*92a65355Syangbillcase, there is little to gain by limiting the free library to free 95*92a65355Syangbillsoftware only, so we use the Lesser General Public License. 96*92a65355Syangbill 97*92a65355Syangbill In other cases, permission to use a particular library in non-free 98*92a65355Syangbillprograms enables a greater number of people to use a large body of 99*92a65355Syangbillfree software. For example, permission to use the GNU C Library in 100*92a65355Syangbillnon-free programs enables many more people to use the whole GNU 101*92a65355Syangbilloperating system, as well as its variant, the GNU/Linux operating 102*92a65355Syangbillsystem. 103*92a65355Syangbill 104*92a65355Syangbill Although the Lesser General Public License is Less protective of the 105*92a65355Syangbillusers' freedom, it does ensure that the user of a program that is 106*92a65355Syangbilllinked with the Library has the freedom and the wherewithal to run 107*92a65355Syangbillthat program using a modified version of the Library. 108*92a65355Syangbill 109*92a65355Syangbill The precise terms and conditions for copying, distribution and 110*92a65355Syangbillmodification follow. Pay close attention to the difference between a 111*92a65355Syangbill"work based on the library" and a "work that uses the library". The 112*92a65355Syangbillformer contains code derived from the library, whereas the latter must 113*92a65355Syangbillbe combined with the library in order to run. 114*92a65355Syangbill 115*92a65355Syangbill GNU LESSER GENERAL PUBLIC LICENSE 116*92a65355Syangbill TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 117*92a65355Syangbill 118*92a65355Syangbill 0. This License Agreement applies to any software library or other 119*92a65355Syangbillprogram which contains a notice placed by the copyright holder or 120*92a65355Syangbillother authorized party saying it may be distributed under the terms of 121*92a65355Syangbillthis Lesser General Public License (also called "this License"). 122*92a65355SyangbillEach licensee is addressed as "you". 123*92a65355Syangbill 124*92a65355Syangbill A "library" means a collection of software functions and/or data 125*92a65355Syangbillprepared so as to be conveniently linked with application programs 126*92a65355Syangbill(which use some of those functions and data) to form executables. 127*92a65355Syangbill 128*92a65355Syangbill The "Library", below, refers to any such software library or work 129*92a65355Syangbillwhich has been distributed under these terms. A "work based on the 130*92a65355SyangbillLibrary" means either the Library or any derivative work under 131*92a65355Syangbillcopyright law: that is to say, a work containing the Library or a 132*92a65355Syangbillportion of it, either verbatim or with modifications and/or translated 133*92a65355Syangbillstraightforwardly into another language. (Hereinafter, translation is 134*92a65355Syangbillincluded without limitation in the term "modification".) 135*92a65355Syangbill 136*92a65355Syangbill "Source code" for a work means the preferred form of the work for 137*92a65355Syangbillmaking modifications to it. For a library, complete source code means 138*92a65355Syangbillall the source code for all modules it contains, plus any associated 139*92a65355Syangbillinterface definition files, plus the scripts used to control compilation 140*92a65355Syangbilland installation of the library. 141*92a65355Syangbill 142*92a65355Syangbill Activities other than copying, distribution and modification are not 143*92a65355Syangbillcovered by this License; they are outside its scope. The act of 144*92a65355Syangbillrunning a program using the Library is not restricted, and output from 145*92a65355Syangbillsuch a program is covered only if its contents constitute a work based 146*92a65355Syangbillon the Library (independent of the use of the Library in a tool for 147*92a65355Syangbillwriting it). Whether that is true depends on what the Library does 148*92a65355Syangbilland what the program that uses the Library does. 149*92a65355Syangbill 150*92a65355Syangbill 1. You may copy and distribute verbatim copies of the Library's 151*92a65355Syangbillcomplete source code as you receive it, in any medium, provided that 152*92a65355Syangbillyou conspicuously and appropriately publish on each copy an 153*92a65355Syangbillappropriate copyright notice and disclaimer of warranty; keep intact 154*92a65355Syangbillall the notices that refer to this License and to the absence of any 155*92a65355Syangbillwarranty; and distribute a copy of this License along with the 156*92a65355SyangbillLibrary. 157*92a65355Syangbill 158*92a65355Syangbill You may charge a fee for the physical act of transferring a copy, 159*92a65355Syangbilland you may at your option offer warranty protection in exchange for a 160*92a65355Syangbillfee. 161*92a65355Syangbill 162*92a65355Syangbill 2. You may modify your copy or copies of the Library or any portion 163*92a65355Syangbillof it, thus forming a work based on the Library, and copy and 164*92a65355Syangbilldistribute such modifications or work under the terms of Section 1 165*92a65355Syangbillabove, provided that you also meet all of these conditions: 166*92a65355Syangbill 167*92a65355Syangbill a) The modified work must itself be a software library. 168*92a65355Syangbill 169*92a65355Syangbill b) You must cause the files modified to carry prominent notices 170*92a65355Syangbill stating that you changed the files and the date of any change. 171*92a65355Syangbill 172*92a65355Syangbill c) You must cause the whole of the work to be licensed at no 173*92a65355Syangbill charge to all third parties under the terms of this License. 174*92a65355Syangbill 175*92a65355Syangbill d) If a facility in the modified Library refers to a function or a 176*92a65355Syangbill table of data to be supplied by an application program that uses 177*92a65355Syangbill the facility, other than as an argument passed when the facility 178*92a65355Syangbill is invoked, then you must make a good faith effort to ensure that, 179*92a65355Syangbill in the event an application does not supply such function or 180*92a65355Syangbill table, the facility still operates, and performs whatever part of 181*92a65355Syangbill its purpose remains meaningful. 182*92a65355Syangbill 183*92a65355Syangbill (For example, a function in a library to compute square roots has 184*92a65355Syangbill a purpose that is entirely well-defined independent of the 185*92a65355Syangbill application. Therefore, Subsection 2d requires that any 186*92a65355Syangbill application-supplied function or table used by this function must 187*92a65355Syangbill be optional: if the application does not supply it, the square 188*92a65355Syangbill root function must still compute square roots.) 189*92a65355Syangbill 190*92a65355SyangbillThese requirements apply to the modified work as a whole. If 191*92a65355Syangbillidentifiable sections of that work are not derived from the Library, 192*92a65355Syangbilland can be reasonably considered independent and separate works in 193*92a65355Syangbillthemselves, then this License, and its terms, do not apply to those 194*92a65355Syangbillsections when you distribute them as separate works. But when you 195*92a65355Syangbilldistribute the same sections as part of a whole which is a work based 196*92a65355Syangbillon the Library, the distribution of the whole must be on the terms of 197*92a65355Syangbillthis License, whose permissions for other licensees extend to the 198*92a65355Syangbillentire whole, and thus to each and every part regardless of who wrote 199*92a65355Syangbillit. 200*92a65355Syangbill 201*92a65355SyangbillThus, it is not the intent of this section to claim rights or contest 202*92a65355Syangbillyour rights to work written entirely by you; rather, the intent is to 203*92a65355Syangbillexercise the right to control the distribution of derivative or 204*92a65355Syangbillcollective works based on the Library. 205*92a65355Syangbill 206*92a65355SyangbillIn addition, mere aggregation of another work not based on the Library 207*92a65355Syangbillwith the Library (or with a work based on the Library) on a volume of 208*92a65355Syangbilla storage or distribution medium does not bring the other work under 209*92a65355Syangbillthe scope of this License. 210*92a65355Syangbill 211*92a65355Syangbill 3. You may opt to apply the terms of the ordinary GNU General Public 212*92a65355SyangbillLicense instead of this License to a given copy of the Library. To do 213*92a65355Syangbillthis, you must alter all the notices that refer to this License, so 214*92a65355Syangbillthat they refer to the ordinary GNU General Public License, version 2, 215*92a65355Syangbillinstead of to this License. (If a newer version than version 2 of the 216*92a65355Syangbillordinary GNU General Public License has appeared, then you can specify 217*92a65355Syangbillthat version instead if you wish.) Do not make any other change in 218*92a65355Syangbillthese notices. 219*92a65355Syangbill 220*92a65355Syangbill Once this change is made in a given copy, it is irreversible for 221*92a65355Syangbillthat copy, so the ordinary GNU General Public License applies to all 222*92a65355Syangbillsubsequent copies and derivative works made from that copy. 223*92a65355Syangbill 224*92a65355Syangbill This option is useful when you wish to copy part of the code of 225*92a65355Syangbillthe Library into a program that is not a library. 226*92a65355Syangbill 227*92a65355Syangbill 4. You may copy and distribute the Library (or a portion or 228*92a65355Syangbillderivative of it, under Section 2) in object code or executable form 229*92a65355Syangbillunder the terms of Sections 1 and 2 above provided that you accompany 230*92a65355Syangbillit with the complete corresponding machine-readable source code, which 231*92a65355Syangbillmust be distributed under the terms of Sections 1 and 2 above on a 232*92a65355Syangbillmedium customarily used for software interchange. 233*92a65355Syangbill 234*92a65355Syangbill If distribution of object code is made by offering access to copy 235*92a65355Syangbillfrom a designated place, then offering equivalent access to copy the 236*92a65355Syangbillsource code from the same place satisfies the requirement to 237*92a65355Syangbilldistribute the source code, even though third parties are not 238*92a65355Syangbillcompelled to copy the source along with the object code. 239*92a65355Syangbill 240*92a65355Syangbill 5. A program that contains no derivative of any portion of the 241*92a65355SyangbillLibrary, but is designed to work with the Library by being compiled or 242*92a65355Syangbilllinked with it, is called a "work that uses the Library". Such a 243*92a65355Syangbillwork, in isolation, is not a derivative work of the Library, and 244*92a65355Syangbilltherefore falls outside the scope of this License. 245*92a65355Syangbill 246*92a65355Syangbill However, linking a "work that uses the Library" with the Library 247*92a65355Syangbillcreates an executable that is a derivative of the Library (because it 248*92a65355Syangbillcontains portions of the Library), rather than a "work that uses the 249*92a65355Syangbilllibrary". The executable is therefore covered by this License. 250*92a65355SyangbillSection 6 states terms for distribution of such executables. 251*92a65355Syangbill 252*92a65355Syangbill When a "work that uses the Library" uses material from a header file 253*92a65355Syangbillthat is part of the Library, the object code for the work may be a 254*92a65355Syangbillderivative work of the Library even though the source code is not. 255*92a65355SyangbillWhether this is true is especially significant if the work can be 256*92a65355Syangbilllinked without the Library, or if the work is itself a library. The 257*92a65355Syangbillthreshold for this to be true is not precisely defined by law. 258*92a65355Syangbill 259*92a65355Syangbill If such an object file uses only numerical parameters, data 260*92a65355Syangbillstructure layouts and accessors, and small macros and small inline 261*92a65355Syangbillfunctions (ten lines or less in length), then the use of the object 262*92a65355Syangbillfile is unrestricted, regardless of whether it is legally a derivative 263*92a65355Syangbillwork. (Executables containing this object code plus portions of the 264*92a65355SyangbillLibrary will still fall under Section 6.) 265*92a65355Syangbill 266*92a65355Syangbill Otherwise, if the work is a derivative of the Library, you may 267*92a65355Syangbilldistribute the object code for the work under the terms of Section 6. 268*92a65355SyangbillAny executables containing that work also fall under Section 6, 269*92a65355Syangbillwhether or not they are linked directly with the Library itself. 270*92a65355Syangbill 271*92a65355Syangbill 6. As an exception to the Sections above, you may also combine or 272*92a65355Syangbilllink a "work that uses the Library" with the Library to produce a 273*92a65355Syangbillwork containing portions of the Library, and distribute that work 274*92a65355Syangbillunder terms of your choice, provided that the terms permit 275*92a65355Syangbillmodification of the work for the customer's own use and reverse 276*92a65355Syangbillengineering for debugging such modifications. 277*92a65355Syangbill 278*92a65355Syangbill You must give prominent notice with each copy of the work that the 279*92a65355SyangbillLibrary is used in it and that the Library and its use are covered by 280*92a65355Syangbillthis License. You must supply a copy of this License. If the work 281*92a65355Syangbillduring execution displays copyright notices, you must include the 282*92a65355Syangbillcopyright notice for the Library among them, as well as a reference 283*92a65355Syangbilldirecting the user to the copy of this License. Also, you must do one 284*92a65355Syangbillof these things: 285*92a65355Syangbill 286*92a65355Syangbill a) Accompany the work with the complete corresponding 287*92a65355Syangbill machine-readable source code for the Library including whatever 288*92a65355Syangbill changes were used in the work (which must be distributed under 289*92a65355Syangbill Sections 1 and 2 above); and, if the work is an executable linked 290*92a65355Syangbill with the Library, with the complete machine-readable "work that 291*92a65355Syangbill uses the Library", as object code and/or source code, so that the 292*92a65355Syangbill user can modify the Library and then relink to produce a modified 293*92a65355Syangbill executable containing the modified Library. (It is understood 294*92a65355Syangbill that the user who changes the contents of definitions files in the 295*92a65355Syangbill Library will not necessarily be able to recompile the application 296*92a65355Syangbill to use the modified definitions.) 297*92a65355Syangbill 298*92a65355Syangbill b) Use a suitable shared library mechanism for linking with the 299*92a65355Syangbill Library. A suitable mechanism is one that (1) uses at run time a 300*92a65355Syangbill copy of the library already present on the user's computer system, 301*92a65355Syangbill rather than copying library functions into the executable, and (2) 302*92a65355Syangbill will operate properly with a modified version of the library, if 303*92a65355Syangbill the user installs one, as long as the modified version is 304*92a65355Syangbill interface-compatible with the version that the work was made with. 305*92a65355Syangbill 306*92a65355Syangbill c) Accompany the work with a written offer, valid for at 307*92a65355Syangbill least three years, to give the same user the materials 308*92a65355Syangbill specified in Subsection 6a, above, for a charge no more 309*92a65355Syangbill than the cost of performing this distribution. 310*92a65355Syangbill 311*92a65355Syangbill d) If distribution of the work is made by offering access to copy 312*92a65355Syangbill from a designated place, offer equivalent access to copy the above 313*92a65355Syangbill specified materials from the same place. 314*92a65355Syangbill 315*92a65355Syangbill e) Verify that the user has already received a copy of these 316*92a65355Syangbill materials or that you have already sent this user a copy. 317*92a65355Syangbill 318*92a65355Syangbill For an executable, the required form of the "work that uses the 319*92a65355SyangbillLibrary" must include any data and utility programs needed for 320*92a65355Syangbillreproducing the executable from it. However, as a special exception, 321*92a65355Syangbillthe materials to be distributed need not include anything that is 322*92a65355Syangbillnormally distributed (in either source or binary form) with the major 323*92a65355Syangbillcomponents (compiler, kernel, and so on) of the operating system on 324*92a65355Syangbillwhich the executable runs, unless that component itself accompanies 325*92a65355Syangbillthe executable. 326*92a65355Syangbill 327*92a65355Syangbill It may happen that this requirement contradicts the license 328*92a65355Syangbillrestrictions of other proprietary libraries that do not normally 329*92a65355Syangbillaccompany the operating system. Such a contradiction means you cannot 330*92a65355Syangbilluse both them and the Library together in an executable that you 331*92a65355Syangbilldistribute. 332*92a65355Syangbill 333*92a65355Syangbill 7. You may place library facilities that are a work based on the 334*92a65355SyangbillLibrary side-by-side in a single library together with other library 335*92a65355Syangbillfacilities not covered by this License, and distribute such a combined 336*92a65355Syangbilllibrary, provided that the separate distribution of the work based on 337*92a65355Syangbillthe Library and of the other library facilities is otherwise 338*92a65355Syangbillpermitted, and provided that you do these two things: 339*92a65355Syangbill 340*92a65355Syangbill a) Accompany the combined library with a copy of the same work 341*92a65355Syangbill based on the Library, uncombined with any other library 342*92a65355Syangbill facilities. This must be distributed under the terms of the 343*92a65355Syangbill Sections above. 344*92a65355Syangbill 345*92a65355Syangbill b) Give prominent notice with the combined library of the fact 346*92a65355Syangbill that part of it is a work based on the Library, and explaining 347*92a65355Syangbill where to find the accompanying uncombined form of the same work. 348*92a65355Syangbill 349*92a65355Syangbill 8. You may not copy, modify, sublicense, link with, or distribute 350*92a65355Syangbillthe Library except as expressly provided under this License. Any 351*92a65355Syangbillattempt otherwise to copy, modify, sublicense, link with, or 352*92a65355Syangbilldistribute the Library is void, and will automatically terminate your 353*92a65355Syangbillrights under this License. However, parties who have received copies, 354*92a65355Syangbillor rights, from you under this License will not have their licenses 355*92a65355Syangbillterminated so long as such parties remain in full compliance. 356*92a65355Syangbill 357*92a65355Syangbill 9. You are not required to accept this License, since you have not 358*92a65355Syangbillsigned it. However, nothing else grants you permission to modify or 359*92a65355Syangbilldistribute the Library or its derivative works. These actions are 360*92a65355Syangbillprohibited by law if you do not accept this License. Therefore, by 361*92a65355Syangbillmodifying or distributing the Library (or any work based on the 362*92a65355SyangbillLibrary), you indicate your acceptance of this License to do so, and 363*92a65355Syangbillall its terms and conditions for copying, distributing or modifying 364*92a65355Syangbillthe Library or works based on it. 365*92a65355Syangbill 366*92a65355Syangbill 10. Each time you redistribute the Library (or any work based on the 367*92a65355SyangbillLibrary), the recipient automatically receives a license from the 368*92a65355Syangbilloriginal licensor to copy, distribute, link with or modify the Library 369*92a65355Syangbillsubject to these terms and conditions. You may not impose any further 370*92a65355Syangbillrestrictions on the recipients' exercise of the rights granted herein. 371*92a65355SyangbillYou are not responsible for enforcing compliance by third parties with 372*92a65355Syangbillthis License. 373*92a65355Syangbill 374*92a65355Syangbill 11. If, as a consequence of a court judgment or allegation of patent 375*92a65355Syangbillinfringement or for any other reason (not limited to patent issues), 376*92a65355Syangbillconditions are imposed on you (whether by court order, agreement or 377*92a65355Syangbillotherwise) that contradict the conditions of this License, they do not 378*92a65355Syangbillexcuse you from the conditions of this License. If you cannot 379*92a65355Syangbilldistribute so as to satisfy simultaneously your obligations under this 380*92a65355SyangbillLicense and any other pertinent obligations, then as a consequence you 381*92a65355Syangbillmay not distribute the Library at all. For example, if a patent 382*92a65355Syangbilllicense would not permit royalty-free redistribution of the Library by 383*92a65355Syangbillall those who receive copies directly or indirectly through you, then 384*92a65355Syangbillthe only way you could satisfy both it and this License would be to 385*92a65355Syangbillrefrain entirely from distribution of the Library. 386*92a65355Syangbill 387*92a65355SyangbillIf any portion of this section is held invalid or unenforceable under any 388*92a65355Syangbillparticular circumstance, the balance of the section is intended to apply, 389*92a65355Syangbilland the section as a whole is intended to apply in other circumstances. 390*92a65355Syangbill 391*92a65355SyangbillIt is not the purpose of this section to induce you to infringe any 392*92a65355Syangbillpatents or other property right claims or to contest validity of any 393*92a65355Syangbillsuch claims; this section has the sole purpose of protecting the 394*92a65355Syangbillintegrity of the free software distribution system which is 395*92a65355Syangbillimplemented by public license practices. Many people have made 396*92a65355Syangbillgenerous contributions to the wide range of software distributed 397*92a65355Syangbillthrough that system in reliance on consistent application of that 398*92a65355Syangbillsystem; it is up to the author/donor to decide if he or she is willing 399*92a65355Syangbillto distribute software through any other system and a licensee cannot 400*92a65355Syangbillimpose that choice. 401*92a65355Syangbill 402*92a65355SyangbillThis section is intended to make thoroughly clear what is believed to 403*92a65355Syangbillbe a consequence of the rest of this License. 404*92a65355Syangbill 405*92a65355Syangbill 12. If the distribution and/or use of the Library is restricted in 406*92a65355Syangbillcertain countries either by patents or by copyrighted interfaces, the 407*92a65355Syangbilloriginal copyright holder who places the Library under this License may add 408*92a65355Syangbillan explicit geographical distribution limitation excluding those countries, 409*92a65355Syangbillso that distribution is permitted only in or among countries not thus 410*92a65355Syangbillexcluded. In such case, this License incorporates the limitation as if 411*92a65355Syangbillwritten in the body of this License. 412*92a65355Syangbill 413*92a65355Syangbill 13. The Free Software Foundation may publish revised and/or new 414*92a65355Syangbillversions of the Lesser General Public License from time to time. 415*92a65355SyangbillSuch new versions will be similar in spirit to the present version, 416*92a65355Syangbillbut may differ in detail to address new problems or concerns. 417*92a65355Syangbill 418*92a65355SyangbillEach version is given a distinguishing version number. If the Library 419*92a65355Syangbillspecifies a version number of this License which applies to it and 420*92a65355Syangbill"any later version", you have the option of following the terms and 421*92a65355Syangbillconditions either of that version or of any later version published by 422*92a65355Syangbillthe Free Software Foundation. If the Library does not specify a 423*92a65355Syangbilllicense version number, you may choose any version ever published by 424*92a65355Syangbillthe Free Software Foundation. 425*92a65355Syangbill 426*92a65355Syangbill 14. If you wish to incorporate parts of the Library into other free 427*92a65355Syangbillprograms whose distribution conditions are incompatible with these, 428*92a65355Syangbillwrite to the author to ask for permission. For software which is 429*92a65355Syangbillcopyrighted by the Free Software Foundation, write to the Free 430*92a65355SyangbillSoftware Foundation; we sometimes make exceptions for this. Our 431*92a65355Syangbilldecision will be guided by the two goals of preserving the free status 432*92a65355Syangbillof all derivatives of our free software and of promoting the sharing 433*92a65355Syangbilland reuse of software generally. 434*92a65355Syangbill 435*92a65355Syangbill NO WARRANTY 436*92a65355Syangbill 437*92a65355Syangbill 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO 438*92a65355SyangbillWARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. 439*92a65355SyangbillEXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR 440*92a65355SyangbillOTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY 441*92a65355SyangbillKIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE 442*92a65355SyangbillIMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 443*92a65355SyangbillPURPOSE.

You can do so by permitting 465*92a65355Syangbillredistribution under these terms (or, alternatively, under the terms of the 466*92a65355Syangbillordinary General Public License). 467*92a65355Syangbill 468*92a65355Syangbill To apply these terms, attach the following notices to the library.
