Artistic License 2.0 

This software Package is Copyright (c) 2009 enStratus Networks LLC.

The Artistic License 2.0 is 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 software Package may be copied, 
modified, distributed, and/or redistributed. 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 Package. If the terms of this license do not permit the full use that 
you propose to make of the Package, you should contact the Copyright 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 Standard 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 organization.

"Distributor Fee" means any fee that you charge for Distributing 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 requested 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, binary, 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, 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.

THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER AND CONTRIBUTORS "AS IS' AND WITHOUT ANY EXPRESS OR
