+This program and the accompanying materials are made available under the
+terms of the Eclipse Public License v. 2.0 which is available at

+# Eclipse Public License - v 2.0
+
+        THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE
+        PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION
+        OF THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
+
+    1. DEFINITIONS
+
+    "Contribution" means:
+
+      a) in the case of the initial Contributor, the initial content
+         Distributed under this Agreement, and
+
+      b) in the case of each subsequent Contributor:
+         i) changes to the Program, and
+         ii) additions to the Program;
+      where such changes and/or additions to the Program originate from
+      and are Distributed by that particular Contributor. A Contribution
+      "originates" from a Contributor if it was added to the Program by
+      such Contributor itself or anyone acting on such Contributor's behalf.
+      Contributions do not include changes or additions to the Program that
+      are not Modified Works.
+
+    "Contributor" means any person or entity that Distributes the Program.
+
+    "Licensed Patents" mean patent claims licensable by a Contributor which
+    are necessarily infringed by the use or sale of its Contribution alone
+    or when combined with the Program.
+
+    "Program" means the Contributions Distributed in accordance with this
+    Agreement.
+
+    "Recipient" means anyone who receives the Program under this Agreement
+    or any Secondary License (as applicable), including Contributors.
+
+    "Derivative Works" shall mean any work, whether in Source Code or other
+    form, that is based on (or derived from) the Program and for which the
+    editorial revisions, annotations, elaborations, or other modifications
+    represent, as a whole, an original work of authorship.
+
+    "Modified Works" shall mean any work in Source Code or other form that
+    results from an addition to, deletion from, or modification of the
+    contents of the Program, including, for purposes of clarity any new file
+    in Source Code form that contains any contents of the Program. Modified
+    Works shall not include works that contain only declarations,
+    interfaces, types, classes, structures, or files of the Program solely
+    in each case in order to link to, bind by name, or subclass the Program
+    or Modified Works thereof.
+
+    "Distribute" means the acts of a) distributing or b) making available
+    in any manner that enables the transfer of a copy.
+
+    "Source Code" means the form of a Program preferred for making
+    modifications, including but not limited to software source code,
+    documentation source, and configuration files.
+
+    "Secondary License" means either the GNU General Public License,
+    Version 2.0, or any later versions of that license, including any
+    exceptions or additional permissions as identified by the initial
+    Contributor.
+
+    2. GRANT OF RIGHTS
+
+      a) Subject to the terms of this Agreement, each Contributor hereby
+      grants Recipient a non-exclusive, worldwide, royalty-free copyright
+      license to reproduce, prepare Derivative Works of, publicly display,
+      publicly perform, Distribute and sublicense the Contribution of such
+      Contributor, if any, and such Derivative Works.
+
+      b) Subject to the terms of this Agreement, each Contributor hereby
+      grants Recipient a non-exclusive, worldwide, royalty-free patent
+      license under Licensed Patents to make, use, sell, offer to sell,
+      import and otherwise transfer the Contribution of such Contributor,
+      if any, in Source Code or other form. This patent license shall
+      apply to the combination of the Contribution and the Program if, at
+      the time the Contribution is added by the Contributor, such addition
+      of the Contribution causes such combination to be covered by the
+      Licensed Patents. The patent license shall not apply to any other
+      combinations which include the Contribution. No hardware per se is
+      licensed hereunder.
+
+      c) Recipient understands that although each Contributor grants the
+      licenses to its Contributions set forth herein, no assurances are
+      provided by any Contributor that the Program does not infringe the
+      patent or other intellectual property rights of any other entity.
+      Each Contributor disclaims any liability to Recipient for claims
+      brought by any other entity based on infringement of intellectual
+      property rights or otherwise. As a condition to exercising the
+      rights and licenses granted hereunder, each Recipient hereby
+      assumes sole responsibility to secure any other intellectual
+      property rights needed, if any. For example, if a third party
+      patent license is required to allow Recipient to Distribute the
+      Program, it is Recipient's responsibility to acquire that license
+      before distributing the Program.
+
+      d) Each Contributor represents that to its knowledge it has
+      sufficient copyright rights in its Contribution, if any, to grant
+      the copyright license set forth in this Agreement.
+
+      e) Notwithstanding the terms of any Secondary License, no
+      Contributor makes additional grants to any Recipient (other than
+      those set forth in this Agreement) as a result of such Recipient's
+      receipt of the Program under the terms of a Secondary License
+      (if permitted under the terms of Section 3).
+
+    3. REQUIREMENTS
+
+    3.1 If a Contributor Distributes the Program in any form, then:
+
+      a) the Program must also be made available as Source Code, in
+      accordance with section 3.2, and the Contributor must accompany
+      the Program with a statement that the Source Code for the Program
+      is available under this Agreement, and informs Recipients how to
+      obtain it in a reasonable manner on or through a medium customarily
+      used for software exchange; and
+
+      b) the Contributor may Distribute the Program under a license
+      different than this Agreement, provided that such license:
+         i) effectively disclaims on behalf of all other Contributors all
+         warranties and conditions, express and implied, including
+         warranties or conditions of title and non-infringement, and
+         implied warranties or conditions of merchantability and fitness
+         for a particular purpose;
+
+         ii) effectively excludes on behalf of all other Contributors all
+         liability for damages, including direct, indirect, special,
+         incidental and consequential damages, such as lost profits;
+
+         iii) does not attempt to limit or alter the recipients' rights
+         in the Source Code under section 3.2; and
+
+         iv) requires any subsequent distribution of the Program by any
+         party to be under a license that satisfies the requirements
+         of this section 3.
+
+    3.2 When the Program is Distributed as Source Code:
+
+      a) it must be made available under this Agreement, or if the
+      Program (i) is combined with other material in a separate file or
+      files made available under a Secondary License, and (ii) the initial
+      Contributor attached to the Source Code the notice described in
+      Exhibit A of this Agreement, then the Program may be made available
+      under the terms of such Secondary Licenses, and
+
+      b) a copy of this Agreement must be included with each copy of
+      the Program.
+
+    3.3 Contributors may not remove or alter any copyright, patent,
+    trademark, attribution notices, disclaimers of warranty, or limitations
+    of liability ("notices") contained within the Program from any copy of
+    the Program which they Distribute, provided that Contributors may add
+    their own appropriate notices.
+
+    4. COMMERCIAL DISTRIBUTION
+
+    Commercial distributors of software may accept certain responsibilities
+    with respect to end users, business partners and the like. While this
+    license is intended to facilitate the commercial use of the Program,
+    the Contributor who includes the Program in a commercial product
+    offering should do so in a manner which does not create potential
+    liability for other Contributors. Therefore, if a Contributor includes
+    the Program in a commercial product offering, such Contributor
+    ("Commercial Contributor") hereby agrees to defend and indemnify every
+    other Contributor ("Indemnified Contributor") against any losses,
+    damages and costs (collectively "Losses") arising from claims, lawsuits
+    and other legal actions brought by a third party against the Indemnified
+    Contributor to the extent caused by the acts or omissions of such
+    Commercial Contributor in connection with its distribution of the Program
+    in a commercial product offering. The obligations in this section do not
+    apply to any claims or Losses relating to any actual or alleged
+    intellectual property infringement. In order to qualify, an Indemnified
+    Contributor must: a) promptly notify the Commercial Contributor in
+    writing of such claim, and b) allow the Commercial Contributor to control,
+    and cooperate with the Commercial Contributor in, the defense and any
+    related settlement negotiations. The Indemnified Contributor may
+    participate in any such claim at its own expense.
+
+    For example, a Contributor might include the Program in a commercial
+    product offering, Product X. That Contributor is then a Commercial
+    Contributor. If that Commercial Contributor then makes performance
+    claims, or offers warranties related to Product X, those performance
+    claims and warranties are such Commercial Contributor's responsibility
+    alone. Under this section, the Commercial Contributor would have to
+    defend claims against the other Contributors related to those performance
+    claims and warranties, and if a court requires any other Contributor to
+    pay any damages as a result, the Commercial Contributor must pay
+    those damages.
+
+    5. NO WARRANTY
+
+    EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
+    PERMITTED BY APPLICABLE LAW, THE PROGRAM IS PROVIDED ON AN "AS IS"
+    BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR
+    IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF
+    TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR
+    PURPOSE. Each Recipient is solely responsible for determining the
+    appropriateness of using and distributing the Program and assumes all
+    risks associated with its exercise of rights under this Agreement,
+    including but not limited to the risks and costs of program errors,
+    compliance with applicable laws, damage to or loss of data, programs
+    or equipment, and unavailability or interruption of operations.
+
+    6. DISCLAIMER OF LIABILITY
+
+    EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT
+    PERMITTED BY APPLICABLE LAW, NEITHER RECIPIENT NOR ANY CONTRIBUTORS
+    SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,
+    EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST
+    PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN
+    CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE)
+    ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE
+    EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE
+    POSSIBILITY OF SUCH DAMAGES.
+
+    7. GENERAL
+
+    If any provision of this Agreement is invalid or unenforceable under
+    applicable law, it shall not affect the validity or enforceability of
+    the remainder of the terms of this Agreement, and without further
+    action by the parties hereto, such provision shall be reformed to the
+    minimum extent necessary to make such provision valid and enforceable.
+
+    If Recipient institutes patent litigation against any entity
+    (including a cross-claim or counterclaim in a lawsuit) alleging that the
+    Program itself (excluding combinations of the Program with other software
+    or hardware) infringes such Recipient's patent(s), then such Recipient's
+    rights granted under Section 2(b) shall terminate as of the date such
+    litigation is filed.
+
+    All Recipient's rights under this Agreement shall terminate if it
+    fails to comply with any of the material terms or conditions of this
+    Agreement and does not cure such failure in a reasonable period of
+    time after becoming aware of such noncompliance. If all Recipient's
+    rights under this Agreement terminate, Recipient agrees to cease use
+    and distribution of the Program as soon as reasonably practicable.
+    However, Recipient's obligations under this Agreement and any licenses
+    granted by Recipient relating to the Program shall continue and survive.
+
+    Everyone is permitted to copy and distribute copies of this Agreement,
+    but in order to avoid inconsistency the Agreement is copyrighted and
+    may only be modified in the following manner. The Agreement Steward
+    reserves the right to publish new versions (including revisions) of
+    this Agreement from time to time. No one other than the Agreement
+    Steward has the right to modify this Agreement. The Eclipse Foundation
+    is the initial Agreement Steward. The Eclipse Foundation may assign the
+    responsibility to serve as the Agreement Steward to a suitable separate
+    entity. Each new version of the Agreement will be given a distinguishing
+    version number. The Program (including Contributions) may always be
+    Distributed subject to the version of the Agreement under which it was
+    received. In addition, after a new version of the Agreement is published,
+    Contributor may elect to Distribute the Program (including its
+    Contributions) under the new version.
+
+    Except as expressly stated in Sections 2(a) and 2(b) above, Recipient
+    receives no rights or licenses to the intellectual property of any
+    Contributor under this Agreement, whether expressly, by implication,
+    estoppel or otherwise. All rights in the Program not expressly granted
+    under this Agreement are reserved. Nothing in this Agreement is intended
+    to be enforceable by any entity that is not a Contributor or Recipient.
+    No third-party beneficiary rights are created under this Agreement.
+
+    Exhibit A - Form of Secondary Licenses Notice
+
+    "This Source Code may also be made available under the following
+    Secondary Licenses when the conditions for such availability set forth
+    in the Eclipse Public License, v. 2.0 are satisfied: {name license(s),
+    version(s), and exceptions or additional permissions here}."
+
+      Simply including a copy of this Agreement, including this Exhibit A
+      is not sufficient to license the Source Code under Secondary Licenses.
+
+      If it is not possible or desirable to put the notice in a particular
+      file, then You may include the notice in a location (such as a LICENSE
+      file in a relevant directory) where a recipient would be likely to
+      look for such a notice.
+
+      You may add additional accurate notices of copyright ownership.

+
+    Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+    51 Franklin Street, Fifth Floor
+    Boston, MA 02110-1335
+    USA
+
+    Everyone is permitted to copy and distribute verbatim copies
+    of this license document, but changing it is not allowed.
+
+    Preamble
+
+    The licenses for most software are designed to take away your freedom to
+    share and change it. By contrast, the GNU General Public License is
+    intended to guarantee your freedom to share and change free software--to
+    make sure the software is free for all its users. This General Public
+    License applies to most of the Free Software Foundation's software and
+    to any other program whose authors commit to using it. (Some other Free
+    Software Foundation software is covered by the GNU Library General
+    Public License instead.) You can apply it to your programs, too.
+
+    When we speak of free software, we are referring to freedom, not price.
+    Our General Public Licenses are designed to make sure that you have the
+    freedom to distribute copies of free software (and charge for this
+    service if you wish), that you receive source code or can get it if you
+    want it, that you can change the software or use pieces of it in new
+    free programs; and that you know you can do these things.
+
+    To protect your rights, we need to make restrictions that forbid anyone
+    to deny you these rights or to ask you to surrender the rights. These
+    restrictions translate to certain responsibilities for you if you
+    distribute copies of the software, or if you modify it.
+
+    For example, if you distribute copies of such a program, whether gratis
+    or for a fee, you must give the recipients all the rights that you have.
+    You must make sure that they, too, receive or can get the source code.
+    And you must show them these terms so they know their rights.
+
+    We protect your rights with two steps: (1) copyright the software, and
+    (2) offer you this license which gives you legal permission to copy,
+    distribute and/or modify the software.
+
+    Also, for each author's protection and ours, we want to make certain
+    that everyone understands that there is no warranty for this free
+    software. If the software is modified by someone else and passed on, we
+    want its recipients to know that what they have is not the original, so
+    that any problems introduced by others will not reflect on the original
+    authors' reputations.
+
+    Finally, any free program is threatened constantly by software patents.
+    We wish to avoid the danger that redistributors of a free program will
+    individually obtain patent licenses, in effect making the program
+    proprietary. To prevent this, we have made it clear that any patent must
+    be licensed for everyone's free use or not licensed at all.
+
+    The precise terms and conditions for copying, distribution and
+    modification follow.
+
+    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+    0. This License applies to any program or other work which contains a
+    notice placed by the copyright holder saying it may be distributed under
+    the terms of this General Public License. The "Program", below, refers
+    to any such program or work, and a "work based on the Program" means
+    either the Program or any derivative work under copyright law: that is
+    to say, a work containing the Program or a portion of it, either
+    verbatim or with modifications and/or translated into another language.
+    (Hereinafter, translation is included without limitation in the term
+    "modification".) Each licensee is addressed as "you".
+
+    Activities other than copying, distribution and modification are not
+    covered by this License; they are outside its scope. The act of running
+    the Program is not restricted, and the output from the Program is
+    covered only if its contents constitute a work based on the Program
+    (independent of having been made by running the Program). Whether that
+    is true depends on what the Program does.
+
+    1. You may copy and distribute 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
+    and disclaimer of warranty; keep intact all the notices that refer to
+    this License and to the absence of any warranty; and give any other
+    recipients of the Program a copy of this License along with the Program.
+
+    You may charge a fee for the physical act of transferring a copy, and
+    you may at your option offer warranty protection in exchange for a fee.
+
+    2. You may modify your copy or copies of the Program or any portion of
+    it, thus forming a work based on the Program, and copy and distribute
+    such modifications or work under the terms of Section 1 above, provided
+    that you also meet all of these conditions:
+
+        a) You must cause the modified files to carry prominent notices
+        stating that you changed the files and the date of any change.
+
+        b) You must cause any work that you distribute or publish, that in
+        whole or in part contains or is derived from the Program or any part
+        thereof, to be licensed as a whole at no charge to all third parties
+        under the terms of this License.
+
+        c) If the modified program normally reads commands interactively
+        when run, you must cause it, when started running for such
+        interactive use in the most ordinary way, to print or display an
+        announcement including an appropriate copyright notice and a notice
+        that there is no warranty (or else, saying that you provide a
+        warranty) and that users may redistribute the program under these
+        conditions, and telling the user how to view a copy of this License.
+        (Exception: if the Program itself is interactive but does not
+        normally print such an announcement, your work based on the Program
+        is not required to print an announcement.)
+
+    These requirements apply to the modified work as a whole. If
+    identifiable sections of that work are not derived from the Program, and
+    can be reasonably considered independent and separate works in
+    themselves, then this License, and its terms, do not apply to those
+    sections when you distribute them as separate works. But when you
+    distribute the same sections as part of a whole which is a work based on
+    the Program, the distribution of the whole must be on the terms of this
+    License, whose permissions for other licensees extend to the entire
+    whole, and thus to each and every part regardless of who wrote it.
+
+    Thus, it is not the intent of this section to claim rights or contest
+    your rights to work written entirely by you; rather, the intent is to
+    exercise the right to control the distribution of derivative or
+    collective works based on the Program.
+
+    In addition, mere aggregation of another work not based on the Program
+    with the Program (or with a work based on the Program) on a volume of a
+    storage or distribution medium does not bring the other work under the
+    scope of this License.
+
+    3. You may copy and distribute the Program (or a work based on it,
+    under Section 2) in object code or executable form under the terms of
+    Sections 1 and 2 above provided that you also do one of the following:
+
+        a) Accompany it with the complete corresponding machine-readable
+        source code, which must be distributed under the terms of Sections 1
+        and 2 above on a medium customarily used for software interchange; or,
+
+        b) Accompany it with a written offer, valid for at least three
+        years, to give any third party, for a charge no more than your cost
+        of physically performing source distribution, a complete
+        machine-readable copy of the corresponding source code, to be
+        distributed under the terms of Sections 1 and 2 above on a medium
+        customarily used for software interchange; or,
+
+        c) Accompany it with the information you received as to the offer to
+        distribute corresponding source code. (This alternative is allowed
+        only for noncommercial distribution and only if you received the
+        program in object code or executable form with such an offer, in
+        accord with Subsection b above.)
+
+    The source code for a work means the preferred form of the work for
+    making modifications to it. For an executable work, complete source code
+    means all the source code for all modules it contains, plus any
+    associated interface definition files, plus the scripts used to control
+    compilation and installation of the executable. However, as a special
+    exception, the source code distributed need not include anything that is
+    normally distributed (in either source or binary form) with the major
+    components (compiler, kernel, and so on) of the operating system on
+    which the executable runs, unless that component itself accompanies the
+    executable.
+
+    If distribution of executable or object code is made by offering access
+    to copy from a designated place, then offering equivalent access to copy
+    the source code from the same place counts as distribution of the source
+    code, even though third parties are not compelled to copy the source
+    along with the object code.
+
+    4. You may not copy, modify, sublicense, or distribute the Program
+    except as expressly provided under this License. Any attempt otherwise
+    to copy, modify, sublicense or distribute the Program is void, and will
+    automatically terminate your rights under this License. However, parties
+    who have received copies, or rights, from you under this License will
+    not have their licenses terminated so long as such parties remain in
+    full compliance.
+
+    5. You are not required to accept this License, since you have not
+    signed it. However, nothing else grants you permission to modify or
+    distribute the Program or its derivative works. These actions are
+    prohibited by law if you do not accept this License. Therefore, by
+    modifying or distributing the Program (or any work based on the
+    Program), you indicate your acceptance of this License to do so, and all
+    its terms and conditions for copying, distributing or modifying the
+    Program or works based on it.
+
+    6. Each time you redistribute the Program (or any work based on the
+    Program), the recipient automatically receives a license from the
+    original licensor to copy, distribute or modify the Program subject to
+    these terms and conditions. You may not impose any further restrictions
+    on the recipients' exercise of the rights granted herein. You are not
+    responsible for enforcing compliance by third parties to this License.
+
+    7. If, as a consequence of a court judgment or allegation of patent
+    infringement or for any other reason (not limited to patent issues),
+    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 distribute
+    so as to satisfy simultaneously your obligations under this License and
+    any other pertinent obligations, then as a consequence you may not
+    distribute the Program at all. For example, if a patent license would
+    not permit royalty-free redistribution of the Program by all those who
+    receive copies directly or indirectly through you, then the only way you
+    could satisfy both it and this License would be to refrain entirely from
+    distribution of the Program.
+
+    If any portion of this section is held invalid or unenforceable under
+    any particular circumstance, the balance of the section is intended to
+    apply and the section as a whole is intended to apply in other
+    circumstances.
+
+    It is not the purpose of this section to induce you to infringe any
+    patents or other property right claims or to contest validity of any
+    such claims; this section has the sole purpose of protecting the
+    integrity of the free software distribution system, which is implemented
+    by public license practices. Many people have made generous
+    contributions to the wide range of software distributed through that
+    system in reliance on consistent application of that system; it is up to
+    the author/donor to decide if he or she is willing to distribute
+    software through any other system and a licensee cannot impose that choice.
+
+    This section is intended to make thoroughly clear what is believed to be
+    a consequence of the rest of this License.
+
+    8. If the distribution and/or use of the Program is restricted in
+    certain countries either by patents or by copyrighted interfaces, the
+    original copyright holder who places the Program under this License may
+    add an explicit geographical distribution limitation excluding those
+    countries, so that distribution is permitted only in or among countries
+    not thus excluded. In such case, this License incorporates the
+    limitation as if written in the body of this License.
+
+    9. The Free Software Foundation may publish revised and/or new
+    versions of the General Public License from time to time. Such new
+    versions will be similar in spirit to the present version, but may
+    differ in detail to address new problems or concerns.
+
+    Each version is given a distinguishing version number. If the Program
+    specifies a version number of this License which applies to it and "any
+    later version", you have the option of following the terms and
+    conditions either of that version or of any later version published by
+    the Free Software Foundation. If the Program does not specify a version
+    number of this License, you may choose any version ever published by the
+    Free Software Foundation.
+
+    10. If you wish to incorporate parts of the Program into other free
+    programs whose distribution conditions are different, write to the
+    author to ask for permission. For software which is copyrighted by the
+    Free Software Foundation, write to the Free Software Foundation; we
+    sometimes make exceptions for this. Our decision will be guided by the
+    two goals of preserving the free status of all derivatives of our free
+    software and of promoting the sharing and reuse of software generally.
+
+    NO WARRANTY
+
+    11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
+    WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+    EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+    OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND,
+    EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH
+    YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+    NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+    12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+    WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+    AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+    THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+    END OF TERMS AND CONDITIONS
+
+    How to Apply These Terms to Your New Programs
+
+    If you develop a new program, and you want it to be of the greatest
+    possible use to the public, the best way to achieve this is to make it
+    free software which everyone can redistribute and change under these terms.
+
+    To do so, attach the following notices to the program. It is safest to
+    attach them to the start of each source file to most effectively convey
+    the exclusion of warranty; and each file should have at least the
+    "copyright" line and a pointer to where the full notice is found.
+
+        One line to give the program's name and a brief idea of what it does.
+        Copyright (C) <year> <name of author>
+
+        This program is free software; you can redistribute it and/or modify
+        it under the terms of the GNU General Public License as published by
+        the Free Software Foundation; either version 2 of the License, or
+        (at your option) any later version.
+
+        This program is distributed in the hope that it will be useful, but
+        WITHOUT ANY WARRANTY; without even the implied warranty of
+        MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+        General Public License for more details.
+
+        You should have received a copy of the GNU General Public License
+        along with this program; if not, write to the Free Software
+        Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1335 USA
+
+    Also add information on how to contact you by electronic and paper mail.
+
+    If the program is interactive, make it output a short notice like this
+    when it starts in an interactive mode:
+
+        Gnomovision version 69, Copyright (C) year name of author
+        Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type
+        `show w'. This is free software, and you are welcome to redistribute
+        it under certain conditions; type `show c' for details.
+
+    The hypothetical commands `show w' and `show c' should show the
+    appropriate parts of the General Public License. Of course, the commands
+    you use may be called something other than `show w' and `show c'; they
+    could even be mouse-clicks or menu items--whatever suits your program.
+
+    You should also get your employer (if you work as a programmer) or your
+    school, if any, to sign a "copyright disclaimer" for the program, if
+    necessary. Here is a sample; alter the names:
+
+        Yoyodyne, Inc., hereby disclaims all copyright interest in the
+        program `Gnomovision' (which makes passes at compilers) written by
+        James Hacker.
+
+        signature of Ty Coon, 1 April 1989
+        Ty Coon, President of Vice
+
+    This General Public License does not permit incorporating your program
+    into proprietary programs. If your program is a subroutine library, you
+    may consider it more useful to permit linking proprietary applications
+    with the library. If this is what you want to do, use the GNU Library
+    General Public License instead of this License.
+
+---
+
+## CLASSPATH EXCEPTION
+
+    Linking this library statically or dynamically with other modules is
+    making a combined work based on this library.  Thus, the terms and
+    conditions of the GNU General Public License version 2 cover the whole
+    combination.
+
+    As a special exception, the copyright holders of this library give you
+    permission to link this library with independent modules to produce an
+    executable, regardless of the license terms of these independent
+    modules, and to copy and distribute the resulting executable under
+    terms of your choice, provided that you also meet, for each linked
+    independent module, the terms and conditions of the license of that
+    module.  An independent module is a module which is not derived from or
+    based on this library.  If you modify this library, you may extend this
+    exception to your version of the library, but you are not obligated to
+    do so.  If you do not wish to do so, delete this exception statement
+    from your version.
