-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 Contributio [...]
-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 here [...]
-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 Con [...]
-
-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  [...]
-
-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 Ag [...]
-
-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 [...]
-
-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 Reci [...]
-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.

-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.

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,

+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 here [...]
+
+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).

+
+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 M [...]
+
+“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 cause [...]
+
+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 here [...]
+
+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 Con [...]
+
+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  [...]
+
+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 assoc [...]
+
+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 EX [...]
+
+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 Reci [...]
+
+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 respons [...]
+
+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.
