 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.

154  must be distributed under the terms of Sections 1 and 2 above on a

162    form) with the major components (compiler, kernel, and so on) of the
163    operating system on which the executable runs, unless that component
164    itself accompanies the executable.
165    
166    If distribution of executable or object code is made by offering
167    access to copy from a designated place, then offering equivalent
168    access to copy the source code from the same place counts as

175  work, in isolation, is not a derivative work of the Library, and  void, and will automatically terminate your rights under this License.

 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.
