Artistic License 2.0

Copyright (c) 2000‐2006, The Perl Foundation.

Everyone  is  permitted to copy and distribute verbatim copies of
this license document, but changing it is not allowed.

Preamble

This license establishes the terms under which a given free soft‐
ware  Package may be copied, modified, distributed, and/or redis‐
tributed. The intent is that the Copyright Holder maintains  some
artistic control over the development of that Package while still
keeping the Package available as open source and free software.

You are always permitted to make arrangements wholly  outside  of
this  license directly with the Copyright Holder of a given Pack‐
age. If the terms of this license do not permit the full use that
you  propose to make of the Package, you should contact the Copy‐
right Holder and seek a different licensing arrangement.

Definitions

   "Copyright Holder" means the individual(s) or  organization(s)
named
   in the copyright notice for the entire Package.

   "Contributor"  means  any  party  that has contributed code or
other
   material to the Package,  in  accordance  with  the  Copyright
Holder’s
   procedures.

   "You" and "your" means any person who would like to copy,
   distribute, or modify the Package.

   "Package" means the collection of files distributed by the
   Copyright Holder, and derivatives of that collection and/or of
   those  files.  A given Package may consist of either the Stan‐
dard
   Version, or a Modified Version.

   "Distribute" means providing a copy of the Package  or  making
it
   accessible to anyone else, or in the case of a company or
   organization,  to  others outside of your company or organiza‐
tion.

   "Distributor Fee" means any fee that you charge for Distribut‐
ing
   this Package or providing support for this Package to another
   party. It does not mean licensing fees.

   "Standard Version" refers to the Package if it has not been
   modified,  or  has  been  modified only in ways explicitly re‐
quested by
   the Copyright Holder.

   "Modified Version" means the Package, if it has been  changed,
and
   such  changes  were  not explicitly requested by the Copyright
Holder.

   "Original License" means this Artistic License as  Distributed
with
   the Standard Version of the Package, in its current version or
as
   it may be modified by The Perl Foundation in the future.

   "Source" form means the source code, documentation source, and
   configuration files for the Package.

   "Compiled" form means the compiled bytecode, object code,  bi‐
nary,
   or any other form resulting from mechanical transformation or
   translation of the Source form.

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,  pro‐
vided 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  restric‐
tion,  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 re‐
sulting 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 lim‐
ited  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 Hold‐
er of
   the Standard Version, under the Original License, so that the
   Copyright  Holder  may include your modifications in the Stan‐
dard
   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 dif‐
ferent
   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 oth‐
ers
   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 li‐
censing
      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  al‐
lowed.
      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  instruc‐
tions  on how to get the Source of the Standard Version. Such in‐
structions 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 in‐
structions or cease distribution within thirty days after you be‐
come  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  with‐
out  the Source, provided that you comply with Section 4 with re‐
spect 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 result‐
ing 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  applica‐
tions that include the Package, and Distribute the result without
restriction, provided the result does not expose a direct  inter‐
face 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  them‐
selves,  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  ac‐
cept this license.

(11)  If  your  Modified Version has been derived from a Modified
Version made by someone other than you, you are nevertheless  re‐
quired to ensure that your Modified Version complies with the re‐
quirements of this license.

(12) This license does not grant you the right to use any  trade‐
mark, 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 contributo‐
ry patent infringement, then this Artistic License to  you  shall
terminate on the date that such litigation is filed.

(14) Disclaimer of Warranty: THE PACKAGE IS PROVIDED BY THE COPY‐
RIGHT HOLDER AND CONTRIBUTORS "AS IS’ AND WITHOUT ANY EXPRESS  OR
IMPLIED  WARRANTIES.  THE  IMPLIED WARRANTIES OF MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE, OR  NON‐INFRINGEMENT  ARE  DIS‐
CLAIMED  TO  THE  EXTENT PERMITTED BY YOUR LOCAL LAW.  UNLESS RE‐
QUIRED BY LAW, NO COPYRIGHT HOLDER OR CONTRIBUTOR WILL BE  LIABLE
FOR  ANY  DIRECT,  INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES
ARISING IN ANY WAY OUT OF THE USE OF THE PACKAGE, EVEN IF ADVISED
OF THE POSSIBILITY OF SUCH DAMAGE.
