+
+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.
+
+(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.

-These requirements apply to the modified work as a whole.  If

-parties remain in full compliance.

+conditions are met.  This License explicitly affirms your unlimited
-You are not responsible for enforcing compliance by third parties to
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
 this License.
 
-  7. If, as a consequence of a court judgment or allegation of patent
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
-infringement or for any other reason (not limited to patent issues),
+patent license under the contributor's essential patent claims, to
-conditions are imposed on you (whether by court order, agreement or
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
+excuse you from the conditions of this License.  If you cannot convey a
