% This license establishes the terms under which a given free software

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 | 
						|
%
 | 
						|
% Permission for Use and Modification Without Distribution
 | 
						|
%
 | 
						|
% (1) You are permitted to use the Standard Version and create and use
 | 
						|
% Modified Versions for any purpose without restriction, provided that
 | 
						|
% you do not Distribute the Modified Version.
 | 
						|
%
 | 
						|
% Permissions for Redistribution of the Standard Version
 | 
						|
%
 | 
						|
% (2) You may Distribute verbatim copies of the Source form of the
 | 
						|
% Standard Version of this Package in any medium without restriction,
 | 
						|
% either gratis or for a Distributor Fee, provided that you duplicate
 | 
						|
% all of the original copyright notices and associated disclaimers. At
 | 
						|
% your discretion, such verbatim copies may or may not include a
 | 
						|
% Compiled form of the Package.
 | 
						|
%
 | 
						|
% (3) You may apply any bug fixes, portability changes, and other
 | 
						|
% modifications made available from the Copyright Holder. The resulting
 | 
						|
% Package will still be considered the Standard Version, and as such
 | 
						|
% will be subject to the Original License.
 | 
						|
%
 | 
						|
% Distribution of Modified Versions of the Package as Source
 | 
						|
%
 | 
						|
% (4) You may Distribute your Modified Version as Source (either gratis
 | 
						|
% or for a Distributor Fee, and with or without a Compiled form of the
 | 
						|
% Modified Version) provided that you clearly document how it differs
 | 
						|
% from the Standard Version, including, but not limited to, documenting
 | 
						|
% any non-standard features, executables, or modules, and provided that
 | 
						|
% you do at least ONE of the following:
 | 
						|
%
 | 
						|
% (a) make the Modified Version available to the Copyright Holder of the
 | 
						|
% Standard Version, under the Original License, so that the Copyright
 | 
						|
% Holder may include your modifications in the Standard Version.  (b)
 | 
						|
% ensure that installation of your Modified Version does not prevent the
 | 
						|
% user installing or running the Standard Version. In addition, the
 | 
						|
% modified Version must bear a name that is different from the name of
 | 
						|
% the Standard Version.  (c) allow anyone who receives a copy of the
 | 
						|
% Modified Version to make the Source form of the Modified Version
 | 
						|
% available to others under (i) the Original License or (ii) a license
 | 
						|
% that permits the licensee to freely copy, modify and redistribute the
 | 
						|
% Modified Version using the same licensing terms that apply to the copy
 | 
						|
% that the licensee received, and requires that the Source form of the
 | 
						|
% Modified Version, and of any works derived from it, be made freely
 | 
						|
% available in that license fees are prohibited but Distributor Fees are
 | 
						|
% allowed.
 | 
						|
%
 | 
						|
% Distribution of Compiled Forms of the Standard Version or
 | 
						|
% Modified Versions without the Source
 | 
						|
%
 | 
						|
% (5) You may Distribute Compiled forms of the Standard Version without
 | 
						|
% the Source, provided that you include complete instructions on how to
 | 
						|
% get the Source of the Standard Version. Such instructions must be
 | 
						|
% valid at the time of your distribution. If these instructions, at any
 | 
						|
% time while you are carrying out such distribution, become invalid, you
 | 
						|
% must provide new instructions on demand or cease further
 | 
						|
% distribution. If you provide valid instructions or cease distribution
 | 
						|
% within thirty days after you become aware that the instructions are
 | 
						|
% invalid, then you do not forfeit any of your rights under this
 | 
						|
% license.
 | 
						|
%
 | 
						|
% (6) You may Distribute a Modified Version in Compiled form without the
 | 
						|
% Source, provided that you comply with Section 4 with respect to the
 | 
						|
% Source of the Modified Version.
 | 
						|
%
 | 
						|
% Aggregating or Linking the Package
 | 
						|
%
 | 
						|
% (7) You may aggregate the Package (either the Standard Version or
 | 
						|
% Modified Version) with other packages and Distribute the resulting
 | 
						|
% aggregation provided that you do not charge a licensing fee for the
 | 
						|
% Package. Distributor Fees are permitted, and licensing fees for other
 | 
						|
% components in the aggregation are permitted. The terms of this license
 | 
						|
% apply to the use and Distribution of the Standard or Modified Versions
 | 
						|
% as included in the aggregation.
 | 
						|
%
 | 
						|
% (8) You are permitted to link Modified and Standard Versions with
 | 
						|
% other works, to embed the Package in a larger work of your own, or to
 | 
						|
% build stand-alone binary or bytecode versions of applications that
 | 
						|
% include the Package, and Distribute the result without restriction,
 | 
						|
% provided the result does not expose a direct interface to the Package.
 | 
						|
%
 | 
						|
% Items That are Not Considered Part of a Modified Version
 | 
						|
%
 | 
						|
% (9) Works (including, but not limited to, modules and scripts) that
 | 
						|
% merely extend or make use of the Package, do not, by themselves, cause
 | 
						|
% the Package to be a Modified Version. In addition, such works are not
 | 
						|
% considered parts of the Package itself, and are not subject to the
 | 
						|
% terms of this license.
 | 
						|
%
 | 
						|
% General Provisions
 | 
						|
%
 | 
						|
% (10) Any use, modification, and distribution of the Standard or
 | 
						|
% Modified Versions is governed by this Artistic License. By using,
 | 
						|
% modifying or distributing the Package, you accept this license. Do not
 | 
						|
% use, modify, or distribute the Package, if you do not accept this
 | 
						|
% license.
 | 
						|
%
 | 
						|
% (11) If your Modified Version has been derived from a Modified Version
 | 
						|
% made by someone other than you, you are nevertheless required to
 | 
						|
% ensure that your Modified Version complies with the requirements of
 | 
						|
% this license.
 | 
						|
%
 | 
						|
% (12) This license does not grant you the right to use any trademark,
 | 
						|
% service mark, tradename, or logo of the Copyright Holder.
 | 
						|
%
 | 
						|
% (13) This license includes the non-exclusive, worldwide,
 | 
						|
% free-of-charge patent license to make, have made, use, offer to sell,
 | 
						|
% sell, import and otherwise transfer the Package with respect to any
 | 
						|
% patent claims licensable by the Copyright Holder that are necessarily
 | 
						|
% infringed by the Pack<age. If you institute patent litigation
 | 
						|
% (including a cross-claim or counterclaim) against any party alleging
 | 
						|
% that the Package constitutes direct or contributory patent
 | 
						|
% infringement, then this Artistic License to you shall terminate on the
 | 
						|
% date that such litigation is filed.
