The Artistic License
Version 2.0beta4, October 2000
Copyright (C) 2000, Larry Wall.
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
This copyright license states the terms under which a given free software
Package may be copied, modified and/or redistributed, while the
Originator(s) maintain some artistic control over the future
development of that Package (at least as much artistic control as can be
given under copyright law while still making the Package open source and
free software).
This license is bound by copyright law, and thus it legally applies only to
works which the copyright holder has permitted copying, distribution or
modification under the terms of the Artistic License, Version 2.0.
You are reminded that You are always permitted to make arrangements wholly
outside of a given copyright license directly with the copyright
holder(s) of a given Package. If the terms of this license
impede your ability to make full use of the Package, You are encouraged to
contact the copyright holder(s) and seek a different licensing
arrangement.
Definitions
"Package" refers to the collection of files distributed by the
Originator(s), and derivatives of that collection of files
created through textual modification.
"Standard Version" refers to the Package if it has not been modified, or
has been modified only in ways suggested by the Originator(s).
"Modified Version" refers to the Package, if it has been changed by You
via textual modification of the source code, and such changes were not
suggested by the Originator(s).
"Originator" refers to the author(s) and/or copyright
holder(s) of the Standard Version of the Package.
"You" and "Your" refers to any person who would like to copy,
distribute, or modify the Package.
"Distribution Fee" is any fee that You charge for providing a copy of
this Package to another party. It does not refer to licensing fees.
"Freely Available" means that:
(a) no fee is charged for the right to use the item (though a
Distribution Fee may be charged).
(b) recipients of the item may redistribute it under the same
conditions they received it.
(c) If the item is a binary, object code, bytecode, the complete
corresponding machine-readable source code is included with the
item.
Permission for Use and Modification Without Redistribution
(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 redistribute the Modified Version to others outside of your
company or organization.
Permissions for Redistribution of the Standard Version
(2) You may make available verbatim copies of the source code of the
Standard Version of this Package in any medium without restriction,
either gratis or for a Distribution 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 compiled
bytecode, object code or binary versions of the corresponding source
code in the same medium.
(3) You may apply any bug fixes, portability changes, and other
modifications made available from any of the Originator(s). The
resulting modified Package will still be considered the Standard
Version, and may be copied, modified and redistributed under the terms
of the original license of the Standard Version as if it were the
Standard Version.
Permissions for Redistribution of Modified Versions of the Package as Source
(4) You may modify your copy of the source code of this Package in any way
and distribute that Modified Version (either gratis or for a
Distribution Fee, and with or without a corresponding binary, bytecode
or object code version of the Modified Version) provided that You
clearly indicate what changes You made to the Package, and provided
that You do at least ONE of the following:
(a) make the Modified Version available to the Originator(s) of the
Standard Version, under the exact license of the Standard
Version, so that the Originator(s) may include your modifications
into the Standard Version (at their discretion).
(b) modify any installation scripts and procedures so that
installation of the Modified Version will never conflict with an
installation of the Standard Version, include for each program
installed by the Modified Version clear documentation describing
how it differs from the Standard Version, and rename your
Modified Version so that the name is substantially different from
the Standard Version.
(c) permit and encourage anyone who receives a copy of the Modified
Version permission to make your modifications Freely Available in
some specific way.
If Your Modified Version is in turn derived from a Modified Version
made by a third party, then You are still required to ensure that Your
Modified Version complies with the requirements of this license.
Permissions for Redistribution of Non-Source Versions of Package
(5) You may distribute binary, object code, bytecode or other non-source
versions of the Standard Version of the Package, provided that you
include complete instructions on where to get the source code 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 our such distribution, become invalid, you must provide new
instructions on demand or cease further distribution. If You 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 binary, object code, bytecode or other non-source
versions of a Modified Version provided that You do at least ONE of
the following:
(a) include a copy of the corresponding source code for the Modified
Version under the terms indicated in (4).
(b) ensure that the installation of Your non-source Modified Version
does not conflict in any way with an installation of the Standard
Version, include for each program installed by the Modified
Version clear documentation describing how it differs from the
Standard Version, and rename your Modified Version so that the
name is substantially different from the Standard Version.
(c) ensure that the Modified Version includes notification of the
changes made from the Standard Version, and offer to provide
machine-readable source code (under a license that permits making
that source code Freely Available) of the Modified Version via
mail order.
Permissions for Inclusion of the Package in Aggregate Works
(7) You may aggregate this 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. Distribution Fees are permitted, and licensing fees for
other packages in the aggregation are permitted. Your permission to
distribute Standard or Modified Versions of the Package is still
subject to the other terms set forth in other sections of this
license.
(8) In addition to the permissions given elsewhere by this license, You
are also permitted to link Modified and Standard Versions of this
Package with other works and distribute the result without
restriction, provided You have produced binary program(s) that do not
overtly expose the interfaces of the Package. This includes
permission to embed the Package in a larger work of your own without
exposing a direct interface to the Package. This also includes
permission to build stand-alone binary or bytecode versions of your
scripts that require the Package, but do not otherwise give the casual
user direct access to the Package itself.
Items That are Never Considered Part of a Modified Version Package
(9) Works (including, but not limited to, subroutines and scripts) that
you have linked or aggregated with the Package that merely extend or
make use of the Package, but are not intended to cause the Package to
operate differently from the Standard Version, 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 bound by
the terms of the Package's license.
Acceptance of License and Disclaimer of Warranty
(10) You are not required to accept this License, since you have not signed
it. However, nothing else grants you permission to copy, modify or
distribute the Standard or Modified Versions of the Package. These
actions are prohibited by copyright law if you do not accept this
License. Therefore, by copying, modifying or distributing Standard
and Modified Versions of the Package, you indicate your acceptance of
the license of the Package.
(11) Disclaimer of Warranty:

LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR

WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE
