          To protect your rights, we need to make restrictions that forbid
  | 
      
      
        | 36 | 
        
         | 
        
         | 
        distributors to deny you these rights or to ask you to surrender these
  | 
      
      
        | 37 | 
        
         | 
        
         | 
        rights.  These restrictions translate to certain responsibilities for
  | 
      
      
        | 38 | 
        
         | 
        
         | 
        you if you distribute copies of the library or if you modify it.
  | 
      
      
        | 39 |

         | 
        
         | 
          For example, if you distribute copies of the library, whether gratis
  | 
      
      
        | 41 | 
        
         | 
        
         | 
        or for a fee, you must give the recipients all the rights that we gave
  | 
      
      
        | 42 | 
        
         | 
        
         | 
        you.  You must make sure that they, too, receive or can get the source
  | 
      
      
        | 43 | 
        
         | 
        
         | 
        code.  If you link other code with the library, you must provide
  | 
      
      
        | 44 | 
        
         | 
        
         | 
        complete object files to the recipients, so that they can relink them

        | 45 | 
        
         | 
        
         | 
        with the library after making changes to the library and recompiling
  | 
      
      
        | 46 | 
        
         | 
        
         | 
        it.  And you must show them these terms so they know their rights.

        | 47 | 
        
         |

         | 
        
         | 
          We protect your rights with a two-step method: (1) we copyright the
  | 
      
      
        | 49 | 
        
         | 
        
         | 
        library, and (2) we offer you this license, which gives you legal
  | 
      
      
        | 50 | 
        
         | 
        
         | 
        permission to copy, distribute and/or modify the library.
  | 
      
      
        | 51 | 
        
         | 
        
         | 
        
  | 
      
      
        | 52 | 
        
         | 
        
         | 
          To protect each distributor, we want to make it very clear that
  | 
      
      
        | 53 | 
        
         | 
        
         | 
        there is no warranty for the free library.  Also, if the library is
  | 
      
      
        | 54 | 
        
         | 
        
         | 
        modified by someone else and passed on, the recipients should know
  | 
      
      
        | 55 | 
        
         | 
        
         | 
        that what they have is not the original version, so that the original
  | 
      
      
        | 56 | 
        
         | 
        
         | 
        author's reputation will not be affected by problems that might be
  | 
      
      
        | 57 | 
        
         | 
        
         | 
        introduced by others.
  | 
      
      
        | 58 |

          Finally, software patents pose a constant threat to the existence of
  | 
      
      
        | 60 | 
        
         | 
        
         | 
        any free program.  We wish to make sure that a company cannot
  | 
      
      
        | 61 | 
        
         | 
        
         | 
        effectively restrict the users of a free program by obtaining a
  | 
      
      
        | 62 | 
        
         | 
        
         | 
        restrictive license from a patent holder.  Therefore, we insist that
  | 
      
      
        | 63 | 
        
         | 
        
         | 
        any patent license obtained for a version of the library must be
  | 
      
      
        | 64 | 
        
         | 
        
         | 
        consistent with the full freedom of use specified in this license.

          Most GNU software, including some libraries, is covered by the

         |

        is quite different from the ordinary General Public License.  We use

         |

        libraries into non-free programs.

          When a program is linked with a library, whether statically or using

        | 74 | 
        
         |

        a shared library, the combination of the two is legally speaking a

         |

        entire combination fits its criteria of freedom.  The Lesser General

        Public License permits more lax criteria for linking other code with

        | 79 | 
        
         |

        the library.

          We call this license the "Lesser" General Public License because it

         |

        of an advantage over competing non-free programs.  These disadvantages

          For example, on rare occasions, there may be a special need to

         |

         |

         |

         |

            its purpose remains meaningful.

         |

        this, you must alter all the notices that refer to this License, so

         |

        therefore falls outside the scope of this License.

         | 
        
         | 
        threshold for this to be true is not precisely defined by law.

         |

         | 
        
         | 
        of these things:
  | 
      
      
        | 285 | 
        
         |

         | 
        
         | 
            a) Accompany the work with the complete corresponding
  | 
      
      
        | 287 | 
        
         |

            changes were used in the work (which must be distributed under

         | 
        
         | 
            Sections 1 and 2 above); and, if the work is an executable linked
  | 
      
      
        | 290 | 
        
         | 
        
         | 
            with the Library, with the complete machine-readable "work that

        | 291 | 
        
         | 
        
         | 
            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

         |

         | 
            Library will not necessarily be able to recompile the application

         |

         | 
        
         | 
            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,

        | 301 | 
        
         | 
        
         | 
            rather than copying library functions into the executable, and (2)

        | 302 | 
        
         | 
        
         | 
            will operate properly with a modified version of the library, if
  | 
      
      
        | 303 | 
        
         | 
        
         | 
            the user installs one, as long as the modified version is
  | 
      
      
        | 304 | 
        
         | 
        
         | 
            interface-compatible with the version that the work was made with.

        | 307 | 
        
         | 
        
         | 
            least three years, to give the same user the materials

        | 308 | 
        
         | 
        
         | 
            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
  | 
      
      
        | 312 | 
        
         | 
        
         | 
            from a designated place, offer equivalent access to copy the above

        | 313 | 
        
         | 
        
         | 
            specified materials from the same place.

         | 
        
         | 
            e) Verify that the user has already received a copy of these
  | 
      
      
        | 316 | 
        
         | 
        
         | 
            materials or that you have already sent this user a copy.

         | 
          For an executable, the required form of the "work that uses the

        reproducing the executable from it.  However, as a special exception,

        the materials to be distributed need not include anything that is

         |

         | 
        
         | 
          It may happen that this requirement contradicts the license
