|
% license directly with the Copyright Holder of a given Package. If the

% or modify the Package.
|
|
%
|
|
% "Package" means the collection of files distributed by the Copyright

|
% be modified by The Perl Foundation in the future.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
|
|
%
|
|
% 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 Package. 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.
