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.
