  4. document, but changing it is not allowed.
  5. Preamble
  6. This license establishes the terms under which a given free software Package
  7. may be copied, modified, distributed, and/or redistributed. The intent is
  8. that the Copyright Holder maintains some artistic control over the development
  9. of that Package while still keeping the Package available as open source and
  10. free software.
  11. You are always permitted to make arrangements wholly outside of this license
  12. directly with the Copyright Holder of a given Package. If the terms of this
  13. license do not permit the full use that you propose to make of the Package,
  14. you should contact the Copyright Holder and seek a different licensing arrangement.

  26. to anyone else, or in the case of a company or organization, to others outside
  27. of your company or organization.
  28. "Distributor Fee" means any fee that you charge for Distributing this Package
  29. or providing support for this Package to another party. It does not mean licensing
  30. fees.
  31. "Standard Version" refers to the Package if it has not been modified, or has
  32. been modified only in ways explicitly requested by the Copyright Holder.
  33. "Modified Version" means the Package, if it has been changed, and such changes
  34. were not explicitly requested by the Copyright Holder.

  39. files for the Package.
  40. "Compiled" form means the compiled bytecode, object code, binary, or any other
  41. form resulting from mechanical transformation or translation of the Source
  42. form.
  43. Permission for Use and Modification Without Distribution
  44. (1) You are permitted to use the Standard Version and create and use Modified
  45. Versions for any purpose without restriction, provided that you do not Distribute
  46. the Modified Version.
  47. Permissions for Redistribution of the Standard Version
  48. (2) You may Distribute verbatim copies of the Source form of the Standard
  49. Version of this Package in any medium without restriction, either gratis or
  50. for a Distributor Fee, provided that you duplicate all of the original copyright
  51. notices and associated disclaimers. At your discretion, such verbatim copies
  52. may or may not include a Compiled form of the Package.
  53. (3) You may apply any bug fixes, portability changes, and other modifications
  54. made available from the Copyright Holder. The resulting Package will still
  55. be considered the Standard Version, and as such will be subject to the Original
  56. License.
  57. Distribution of Modified Versions of the Package as Source
  58. (4) You may Distribute your Modified Version as Source (either gratis or for
  59. a Distributor Fee, and with or without a Compiled form of the Modified Version)
  60. provided that you clearly document how it differs from the Standard Version,
  61. including, but not limited to, documenting any non-standard features, executables,
  62. or modules, and provided that you do at least ONE of the following:
  63. (a) make the Modified Version available to the Copyright Holder of the Standard
  64. Version, under the Original License, so that the Copyright Holder may include
  65. your modifications in the Standard Version.
  66. (b) ensure that installation of your Modified Version does not prevent the
  67. user installing or running the Standard Version. In addition, the Modified
  68. Version must bear a name that is different from the name of the Standard Version.
  69. (c) allow anyone who receives a copy of the Modified Version to make the Source
  70. form of the Modified Version available to others under
  71. (i) the Original License or
  72. (ii) a license that permits the licensee to freely copy, modify and redistribute
  73. the Modified Version using the same licensing terms that apply to the copy
  74. that the licensee received, and requires that the Source form of the Modified
  75. Version, and of any works derived from it, be made freely available in that
  76. license fees are prohibited but Distributor Fees are allowed.
  77. Distribution of Compiled Forms of the Standard Version or Modified Versions
  78. without the Source
  79. (5) You may Distribute Compiled forms of the Standard Version without the
  80. Source, provided that you include complete instructions on how to get the
  81. Source of the Standard Version. Such instructions must be valid at the time
  82. of your distribution. If these instructions, at any time while you are carrying
  83. out such distribution, become invalid, you must provide new instructions on
  84. demand or cease further distribution. If you provide valid instructions or
  85. cease distribution within thirty days after you become aware that the instructions
  86. are invalid, then you do not forfeit any of your rights under this license.
  87. (6) You may Distribute a Modified Version in Compiled form without the Source,
  88. provided that you comply with Section 4 with respect to the Source of the
  89. Modified Version.
  90. Aggregating or Linking the Package
  91. (7) You may aggregate the Package (either the Standard Version or Modified
  92. Version) with other packages and Distribute the resulting aggregation provided
  93. that you do not charge a licensing fee for the Package. Distributor Fees are
  94. permitted, and licensing fees for other components in the aggregation are
  95. permitted. The terms of this license apply to the use and Distribution of
  96. the Standard or Modified Versions as included in the aggregation.
  97. (8) You are permitted to link Modified and Standard Versions with other works,
  98. to embed the Package in a larger work of your own, or to build stand-alone
  99. binary or bytecode versions of applications that include the Package, and
  100. Distribute the result without restriction, provided the result does not expose
  101. a direct interface to the Package.
  102. Items That are Not Considered Part of a Modified Version
  103. (9) Works (including, but not limited to, modules and scripts) that merely
  104. extend or make use of the Package, do not, by themselves, cause the Package
  105. to be a Modified Version. In addition, such works are not considered parts
  106. of the Package itself, and are not subject to the terms of this license.
  107. General Provisions
  108. (10) Any use, modification, and distribution of the Standard or Modified Versions
  109. is governed by this Artistic License. By using, modifying or distributing
  110. the Package, you accept this license. Do not use, modify, or distribute the
  111. Package, if you do not accept this license.
  112. (11) If your Modified Version has been derived from a Modified Version made
  113. by someone other than you, you are nevertheless required to ensure that your
  114. Modified Version complies with the requirements of this license.
  115. (12) This license does not grant you the right to use any trademark, service
  116. mark, tradename, or logo of the Copyright Holder.

  118. license to make, have made, use, offer to sell, sell, import and otherwise
  119. transfer the Package with respect to any patent claims licensable by the Copyright
  120. Holder that are necessarily infringed by the Package. If you institute patent
  121. litigation (including a cross-claim or counterclaim) against any party alleging
  122. that the Package constitutes direct or contributory patent infringement, then
  123. this Artistic License to you shall terminate on the date that such litigation
  124. is filed.

  126. THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER AND CONTRIBUTORS "AS IS" AND

  132. OF THE POSSIBILITY OF SUCH DAMAGE.
