This program is free software; you can redistribute it and/or modify
it under the terms of the Artistic License, which comes with Perl.

On Debian systems, the complete text of the Artistic License
can be found in `/usr/share/common-licenses/Artistic'. 

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, 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.

(14) Disclaimer of Warranty: THE PACKAGE IS PROVIDED BY THE COPYRIGHT
     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
     DISCLAIMED TO THE EXTENT PERMITTED BY YOUR LOCAL LAW. UNLESS
     REQUIRED 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. 

Creative Commons Attribution-ShareAlike 4.0 International Public License

Attribution-ShareAlike 4.0 International Public License ("Public
License"). To the extent this Public License may be interpreted as a
contract, You are granted the Licensed Rights in consideration of Your

    equivalent rights anywhere in the world.
 m. You means the individual or entity exercising the Licensed Rights

Section 2 – Scope.

 a. License grant.

      1. Subject to the terms and conditions of this Public License,
         the Licensor hereby grants You a worldwide, royalty-free,
         non-sublicensable, non-exclusive, irrevocable license to
         exercise the Licensed Rights in the Licensed Material to:

           A. reproduce and Share the Licensed Material, in whole or
              in part; and
           B. produce, reproduce, and Share Adapted Material.

      2. Exceptions and Limitations. For the avoidance of doubt, where
         Exceptions and Limitations apply to Your use, this Public
         License does not apply, and You do not need to comply with
         its terms and conditions.
      3. Term. The term of this Public License is specified in Section
         6(a).
      4. Media and formats; technical modifications allowed. The
         Licensor authorizes You to exercise the Licensed Rights in
         all media and formats whether now known or hereafter created,
         and to make technical modifications necessary to do so. The
         Licensor waives and/or agrees not to assert any right or
         authority to forbid You from making technical modifications
         necessary to exercise the Licensed Rights, including
         technical modifications necessary to circumvent Effective
         Technological Measures. For purposes of this Public License,
         simply making modifications authorized by this Section
         2(a)(4) never produces Adapted Material.
      5. Downstream recipients.

           A. Offer from the Licensor – Licensed Material. Every
              recipient of the Licensed Material automatically
              receives an offer from the Licensor to exercise the
              Licensed Rights under the terms and conditions of this
              Public License.
           B. Additional offer from the Licensor – Adapted Material.
              Every recipient of Adapted Material from You
              automatically receives an offer from the Licensor to
              exercise the Licensed Rights in the Adapted Material
              under the conditions of the Adapter’s License You apply.
           C. No downstream restrictions. You may not offer or impose
              any additional or different terms or conditions on, or
              apply any Effective Technological Measures to, the
              Licensed Material if doing so restricts exercise of the
              Licensed Rights by any recipient of the Licensed
              Material.

      6. No endorsement. Nothing in this Public License constitutes or
         may be construed as permission to assert or imply that You
         are, or that Your use of the Licensed Material is, connected
         with, or sponsored, endorsed, or granted official status by,
         the Licensor or others designated to receive attribution as
         provided in Section 3(a)(1)(A)(i).

 b. Other rights.

      1. Moral rights, such as the right of integrity, are not
         licensed under this Public License, nor are publicity,
         privacy, and/or other similar personality rights; however, to
         the extent possible, the Licensor waives and/or agrees not to
         assert any such rights held by the Licensor to the limited
         extent necessary to allow You to exercise the Licensed
         Rights, but not otherwise.
      2. Patent and trademark rights are not licensed under this
         Public License.
      3. To the extent possible, the Licensor waives any right to
         collect royalties from You for the exercise of the Licensed
         Rights, whether directly or through a collecting society
         under any voluntary or waivable statutory or compulsory
         licensing scheme. In all other cases the Licensor expressly
         reserves any right to collect such royalties.

Section 3 – License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the
following conditions.

 a. Attribution.

      1. If You Share the Licensed Material (including in modified
         form), You must:

           A. retain the following if it is supplied by the Licensor
              with the Licensed Material:

               i. identification of the creator(s) of the Licensed
                  Material and any others designated to receive
                  attribution, in any reasonable manner requested by
                  the Licensor (including by pseudonym if designated);
               ii. a copyright notice;
               iii. a notice that refers to this Public License;
               iv. a notice that refers to the disclaimer of
                   warranties;
               v. a URI or hyperlink to the Licensed Material to the
                  extent reasonably practicable;

           B. indicate if You modified the Licensed Material and
              retain an indication of any previous modifications; and
           C. indicate the Licensed Material is licensed under this
              Public License, and include the text of, or the URI or
              hyperlink to, this Public License.

      2. You may satisfy the conditions in Section 3(a)(1) in any
         reasonable manner based on the medium, means, and context in
         which You Share the Licensed Material. For example, it may be
         reasonable to satisfy the conditions by providing a URI or
         hyperlink to a resource that includes the required
         information.
      3. If requested by the Licensor, You must remove any of the
         information required by Section 3(a)(1)(A) to the extent
         reasonably practicable.

 b. ShareAlike.

    In addition to the conditions in Section 3(a), if You Share
    Adapted Material You produce, the following conditions also apply.

      1. The Adapter’s License You apply must be a Creative Commons
         license with the same License Elements, this version or
         later, or a BY-SA Compatible License.
      2. You must include the text of, or the URI or hyperlink to, the
         Adapter's License You apply. You may satisfy this condition
         in any reasonable manner based on the medium, means, and
         context in which You Share Adapted Material.
      3. You may not offer or impose any additional or different terms
         or conditions on, or apply any Effective Technological
         Measures to, Adapted Material that restrict exercise of the
         rights granted under the Adapter's License You apply.

Section 4 – Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that
apply to Your use of the Licensed Material:

 a. for the avoidance of doubt, Section 2(a)(1) grants You the right
    to extract, reuse, reproduce, and Share all or a substantial
    portion of the contents of the database;
 b. if You include all or a substantial portion of the database
    contents in a database in which You have Sui Generis Database
    Rights, then the database in which You have Sui Generis Database
    Rights (but not its individual contents) is Adapted Material,
    including for purposes of Section 3(b); and
 c. You must comply with the conditions in Section 3(a) if You Share
    all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not
replace Your obligations under this Public License where the Licensed
Rights include other Copyright and Similar Rights.

Section 5 – Disclaimer of Warranties and Limitation of Liability.

 a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
    EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
    AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
    ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
    IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
    WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
    PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
    ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
    KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
    ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
 b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE TO
    YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
    NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
    INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
    COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
    USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
    ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
    DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
    IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
 c. the disclaimer of warranties and limitation of liability provided
    above shall be interpreted in a manner that, to the extent
    possible, most closely approximates an absolute disclaimer and
    waiver of all liability.

Section 6 – Term and Termination.

 a. This Public License applies for the term of the Copyright and
    Similar Rights licensed here. However, if You fail to comply with
    this Public License, then Your rights under this Public License
    terminate automatically.
 b. Where Your right to use the Licensed Material has terminated under
    Section 6(a), it reinstates:

      1. automatically as of the date the violation is cured, provided
         it is cured within 30 days of Your discovery of the
         violation; or
      2. upon express reinstatement by the Licensor.

    For the avoidance of doubt, this Section 6(b) does not affect any
    right the Licensor may have to seek remedies for Your violations
    of this Public License.
 c. For the avoidance of doubt, the Licensor may also offer the
    Licensed Material under separate terms or conditions or stop
    distributing the Licensed Material at any time; however, doing so
    will not terminate this Public License.
 d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
    License.

Section 7 – Other Terms and Conditions.

 a. The Licensor shall not be bound by any additional or different
    terms or conditions communicated by You unless expressly agreed.
 b. Any arrangements, understandings, or agreements regarding the
    Licensed Material not stated herein are separate from and
    independent of the terms and conditions of this Public License.

Section 8 – Interpretation.

 a. For the avoidance of doubt, this Public License does not, and
    shall not be interpreted to, reduce, limit, restrict, or impose
    conditions on any use of the Licensed Material that could lawfully
    be made without permission under this Public License.
 b. To the extent possible, if any provision of this Public License is
    deemed unenforceable, it shall be automatically reformed to the
    minimum extent necessary to make it enforceable. If the provision
    cannot be reformed, it shall be severed from this Public License
    without affecting the enforceability of the remaining terms and
    conditions.
 c. No term or condition of this Public License will be waived and no
    failure to comply consented to unless expressly agreed to by the
    Licensor.
 d. Nothing in this Public License constitutes or may be interpreted
    as a limitation upon, or waiver of, any privileges and immunities
    that apply to the Licensor or You, including from the legal
    processes of any jurisdiction or authority.
