+    <p>THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE
+      PUBLIC LICENSE (&ldquo;AGREEMENT&rdquo;). ANY USE, REPRODUCTION OR DISTRIBUTION
+      OF THE PROGRAM CONSTITUTES RECIPIENT&#039;S ACCEPTANCE OF THIS AGREEMENT.
+    </p>
+    <h2 id="definitions">1. DEFINITIONS</h2>
+    <p>&ldquo;Contribution&rdquo; means:</p>
+    <ul>
+      <li>a) in the case of the initial Contributor, the initial content
+        Distributed under this Agreement, and
+      </li>
+      <li>
+        b) in the case of each subsequent Contributor:
+        <ul>
+          <li>i) changes to the Program, and</li>
+          <li>ii) additions to the Program;</li>
+        </ul>
+        where such changes and/or additions to the Program originate from
+        and are Distributed by that particular Contributor. A Contribution
+        &ldquo;originates&rdquo; from a Contributor if it was added to the Program by such
+        Contributor itself or anyone acting on such Contributor&#039;s behalf.
+        Contributions do not include changes or additions to the Program that
+        are not Modified Works.
+      </li>
+    </ul>
+    <p>&ldquo;Contributor&rdquo; means any person or entity that Distributes the Program.</p>
+    <p>&ldquo;Licensed Patents&rdquo; 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.
+    </p>
+    <p>&ldquo;Program&rdquo; means the Contributions Distributed in accordance with this
+      Agreement.
+    </p>
+    <p>&ldquo;Recipient&rdquo; means anyone who receives the Program under this Agreement
+      or any Secondary License (as applicable), including Contributors.
+    </p>
+    <p>&ldquo;Derivative Works&rdquo; 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.
+    </p>
+    <p>&ldquo;Modified Works&rdquo; 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.
+    </p>
+    <p>&ldquo;Distribute&rdquo; means the acts of a) distributing or b) making available
+      in any manner that enables the transfer of a copy.
+    </p>
+    <p>&ldquo;Source Code&rdquo; means the form of a Program preferred for making
+      modifications, including but not limited to software source code,
+      documentation source, and configuration files.
+    </p>
+    <p>&ldquo;Secondary License&rdquo; 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.
+    </p>
+    <h2 id="grant-of-rights">2. GRANT OF RIGHTS</h2>
+    <ul>
+      <li>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.
+      </li>
+      <li>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.
+      </li>
+      <li>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&#039;s
+        responsibility to acquire that license before distributing the Program.
+      </li>
+      <li>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.
+      </li>
+      <li>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&#039;s receipt of the
+        Program under the terms of a Secondary License (if permitted under
+        the terms of Section 3).
+      </li>
+    </ul>
+    <h2 id="requirements">3. REQUIREMENTS</h2>
+    <p>3.1 If a Contributor Distributes the Program in any form, then:</p>
+    <ul>
+      <li>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
+      </li>
+      <li>
+        b) the Contributor may Distribute the Program under a license
+        different than this Agreement, provided that such license:
+        <ul>
+          <li>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;
+          </li>
+          <li>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;
+          </li>
+          <li>iii) does not attempt to limit or alter the recipients&#039; rights in the
+            Source Code under section 3.2; and
+          </li>
+          <li>iv) requires any subsequent distribution of the Program by any party
+            to be under a license that satisfies the requirements of this section 3.
+          </li>
+        </ul>
+      </li>
+    </ul>
+    <p>3.2 When the Program is Distributed as Source Code:</p>
+    <ul>
+      <li>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
+      </li>
+      <li>b) a copy of this Agreement must be included with each copy of the Program.</li>
+    </ul>
+    <p>3.3 Contributors may not remove or alter any copyright, patent, trademark,
+      attribution notices, disclaimers of warranty, or limitations of liability
+      (&lsquo;notices&rsquo;) contained within the Program from any copy of the Program which
+      they Distribute, provided that Contributors may add their own appropriate
+      notices.
+    </p>
+    <h2 id="commercial-distribution">4. COMMERCIAL DISTRIBUTION</h2>
+    <p>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 (&ldquo;Commercial Contributor&rdquo;)
+      hereby agrees to defend and indemnify every other Contributor
+      (&ldquo;Indemnified Contributor&rdquo;) against any losses, damages and costs
+      (collectively &ldquo;Losses&rdquo;) 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.
+    </p>
+    <p>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&#039;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.
+    </p>
+    <h2 id="warranty">5. NO WARRANTY</h2>
+    <p>EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, AND TO THE EXTENT PERMITTED
+      BY APPLICABLE LAW, THE PROGRAM IS PROVIDED ON AN &ldquo;AS IS&rdquo; 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.
+    </p>
+    <h2 id="disclaimer">6. DISCLAIMER OF LIABILITY</h2>
+    <p>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.
+    </p>
+    <h2 id="general">7. GENERAL</h2>
+    <p>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.
+    </p>
+    <p>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&#039;s patent(s), then such Recipient&#039;s rights granted
+      under Section 2(b) shall terminate as of the date such litigation is filed.
+    </p>
+    <p>All Recipient&#039;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&#039;s rights under this Agreement
+      terminate, Recipient agrees to cease use and distribution of the Program
+      as soon as reasonably practicable. However, Recipient&#039;s obligations under
+      this Agreement and any licenses granted by Recipient relating to the
+      Program shall continue and survive.
+    </p>
+    <p>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.
+    </p>
+    <p>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.
+    </p>
