+Eclipse Public License - v 1.0
+
+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 code and documentation
+   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 additions to the Program which: (i) are separate modules of
+   software distributed in conjunction with the Program under their own
+   license agreement, and (ii) are not derivative works of the Program.
+
+"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,
+including all Contributors.
+
+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, in source code and object code form.
+  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 and
+     object code 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.
+
+3. REQUIREMENTS
+
+A Contributor may choose to distribute the Program in object code form under
+its own license agreement, provided that:
+
+  a) it complies with the terms and conditions of this Agreement; and
+  b) its license agreement:
+      i) effectively disclaims on behalf of all 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 Contributors all liability for
+         damages, including direct, indirect, special, incidental and
+         consequential damages, such as lost profits;
+    iii) states that any provisions which differ from this Agreement are
+         offered by that Contributor alone and not by any other party; and
+     iv) states that source code for the Program is available from such
+         Contributor, and informs licensees how to obtain it in a reasonable
+         manner on or through a medium customarily used for software exchange.
+
+When the Program is made available in source code form:
+
+  a) it must be made available under this Agreement; and
+  b) a copy of this Agreement must be included with each copy of the Program.
+     Contributors may not remove or alter any copyright notices contained
+     within the Program.
+
+Each Contributor must identify itself as the originator of its Contribution,
+if
+any, in a manner that reasonably allows subsequent Recipients to identify the
+originator of the Contribution.
+
+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, 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, 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.
+
+This Agreement is governed by the laws of the State of New York and the
+intellectual property laws of the United States of America. No party to this
+Agreement will bring a legal action under this Agreement more than one year
+after the cause of action arose. Each party waives its rights to a jury trial in
+any resulting litigation.
