  1. GNU LESSER GENERAL PUBLIC LICENSE
  2. Version 3, 29 June 2007
  3. Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
  4. Everyone is permitted to copy and distribute verbatim copies
  5. of this license document, but changing it is not allowed.
  6. This version of the GNU Lesser General Public License incorporates
  7. the terms and conditions of version 3 of the GNU General Public
  8. License, supplemented by the additional permissions listed below.
  9. 0. Additional Definitions.
  10. As used herein, "this License" refers to version 3 of the GNU Lesser
  11. General Public License, and the "GNU GPL" refers to version 3 of the GNU
  12. General Public License.
  13. "The Library" refers to a covered work governed by this License,
  14. other than an Application or a Combined Work as defined below.
  15. An "Application" is any work that makes use of an interface provided
  16. by the Library, but which is not otherwise based on the Library.
  17. Defining a subclass of a class defined by the Library is deemed a mode
  18. of using an interface provided by the Library.
  19. A "Combined Work" is a work produced by combining or linking an
  20. Application with the Library. The particular version of the Library
  21. with which the Combined Work was made is also called the "Linked
  22. Version".
  23. The "Minimal Corresponding Source" for a Combined Work means the
  24. Corresponding Source for the Combined Work, excluding any source code
  25. for portions of the Combined Work that, considered in isolation, are
  26. based on the Application, and not on the Linked Version.
  27. The "Corresponding Application Code" for a Combined Work means the
  28. object code and/or source code for the Application, including any data
  29. and utility programs needed for reproducing the Combined Work from the
  30. Application, but excluding the System Libraries of the Combined Work.
  31. 1. Exception to Section 3 of the GNU GPL.
  32. You may convey a covered work under sections 3 and 4 of this License
  33. without being bound by section 3 of the GNU GPL.
  34. 2. Conveying Modified Versions.
  35. If you modify a copy of the Library, and, in your modifications, a
  36. facility refers to a function or data to be supplied by an Application
  37. that uses the facility (other than as an argument passed when the
  38. facility is invoked), then you may convey a copy of the modified
  39. version:
  40. a) under this License, provided that you make a good faith effort to
  41. ensure that, in the event an Application does not supply the
  42. function or data, the facility still operates, and performs
  43. whatever part of its purpose remains meaningful, or
  44. b) under the GNU GPL, with none of the additional permissions of
  45. this License applicable to that copy.
  46. 3. Object Code Incorporating Material from Library Header Files.
  47. The object code form of an Application may incorporate material from
  48. a header file that is part of the Library. You may convey such object
  49. code under terms of your choice, provided that, if the incorporated
  50. material is not limited to numerical parameters, data structure
  51. layouts and accessors, or small macros, inline functions and templates
  52. (ten or fewer lines in length), you do both of the following:
  53. a) Give prominent notice with each copy of the object code that the
  54. Library is used in it and that the Library and its use are
  55. covered by this License.
  56. b) Accompany the object code with a copy of the GNU GPL and this license
  57. document.
  58. 4. Combined Works.
  59. You may convey a Combined Work under terms of your choice that,
  60. taken together, effectively do not restrict modification of the
  61. portions of the Library contained in the Combined Work and reverse
  62. engineering for debugging such modifications, if you also do each of
  63. the following:
  64. a) Give prominent notice with each copy of the Combined Work that
  65. the Library is used in it and that the Library and its use are
  66. covered by this License.
  67. b) Accompany the Combined Work with a copy of the GNU GPL and this license
  68. document.
  69. c) For a Combined Work that displays copyright notices during
  70. execution, include the copyright notice for the Library among
  71. these notices, as well as a reference directing the user to the
  72. copies of the GNU GPL and this license document.
  73. d) Do one of the following:
  74. 0) Convey the Minimal Corresponding Source under the terms of this
  75. License, and the Corresponding Application Code in a form
  76. suitable for, and under terms that permit, the user to
  77. recombine or relink the Application with a modified version of
  78. the Linked Version to produce a modified Combined Work, in the
  79. manner specified by section 6 of the GNU GPL for conveying
  80. Corresponding Source.
  81. 1) Use a suitable shared library mechanism for linking with the
  82. Library. A suitable mechanism is one that (a) uses at run time
  83. a copy of the Library already present on the user's computer
  84. system, and (b) will operate properly with a modified version
  85. of the Library that is interface-compatible with the Linked
  86. Version.
  87. e) Provide Installation Information, but only if you would otherwise
  88. be required to provide such information under section 6 of the
  89. GNU GPL, and only to the extent that such information is
  90. necessary to install and execute a modified version of the
  91. Combined Work produced by recombining or relinking the
  92. Application with a modified version of the Linked Version. (If
  93. you use option 4d0, the Installation Information must accompany
  94. the Minimal Corresponding Source and Corresponding Application
  95. Code. If you use option 4d1, you must provide the Installation
  96. Information in the manner specified by section 6 of the GNU GPL
  97. for conveying Corresponding Source.)
  98. 5. Combined Libraries.
  99. You may place library facilities that are a work based on the
  100. Library side by side in a single library together with other library
  101. facilities that are not Applications and are not covered by this
  102. License, and convey such a combined library under terms of your
  103. choice, if you do both of the following:
  104. a) Accompany the combined library with a copy of the same work based
  105. on the Library, uncombined with any other library facilities,
  106. conveyed under the terms of this License.
  107. b) Give prominent notice with the combined library that part of it
  108. is a work based on the Library, and explaining where to find the
  109. accompanying uncombined form of the same work.
  110. 6. Revised Versions of the GNU Lesser General Public License.
  111. The Free Software Foundation may publish revised and/or new versions
  112. of the GNU Lesser General Public License from time to time. Such new
  113. versions will be similar in spirit to the present version, but may
  114. differ in detail to address new problems or concerns.
  115. Each version is given a distinguishing version number. If the
  116. Library as you received it specifies that a certain numbered version
  117. of the GNU Lesser General Public License "or any later version"
  118. applies to it, you have the option of following the terms and
  119. conditions either of that published version or of any later version
  120. published by the Free Software Foundation. If the Library as you
  121. received it does not specify a version number of the GNU Lesser
  122. General Public License, you may choose any version of the GNU Lesser
  123. General Public License ever published by the Free Software Foundation.
  124. If the Library as you received it specifies that a proxy can decide
  125. whether future versions of the GNU Lesser General Public License shall
  126. apply, that proxy's public statement of acceptance of any version is
  127. permanent authorization for you to choose that version for the
  128. Library.
