+\n\
+Usage Of Content\n\
+\n\
+THE ECLIPSE FOUNDATION MAKES AVAILABLE SOFTWARE, DOCUMENTATION, INFORMATION AND/OR\n\
+OTHER MATERIALS FOR OPEN SOURCE PROJECTS (COLLECTIVELY "CONTENT").\n\
+USE OF THE CONTENT IS GOVERNED BY THE TERMS AND CONDITIONS OF THIS\n\
+AGREEMENT AND/OR THE TERMS AND CONDITIONS OF LICENSE AGREEMENTS OR\n\

+OF ANY APPLICABLE LICENSE AGREEMENTS OR NOTICES INDICATED OR REFERENCED\n\
+BELOW, THEN YOU MAY NOT USE THE CONTENT.\n\
+\n\
+Applicable Licenses\n\
+\n\
+Unless otherwise indicated, all Content made available by the Eclipse Foundation\n\
+is provided to you under the terms and conditions of the Eclipse Public\n\
+License Version 1.0 ("EPL"). A copy of the EPL is provided with this\n\
+Content and is also available at http://www.eclipse.org/legal/epl-v10.html.\n\
+For purposes of the EPL, "Program" will mean the Content.\n\
+\n\
+Content includes, but is not limited to, source code, object code,\n\
+documentation and other files maintained in the Eclipse.org CVS\n\
+repository ("Repository") in CVS modules ("Modules") and made available\n\
+as downloadable archives ("Downloads").\n\
+\n\
+   - Content may be structured and packaged into modules to facilitate delivering,\n\
+     extending, and upgrading the Content. Typical modules may include plug-ins ("Plug-ins"),\n\
+     plug-in fragments ("Fragments"), and features ("Features").\n\
+   - Each Plug-in or Fragment may be packaged as a sub-directory or JAR (Java? ARchive)\n\
+     in a directory named "plugins".\n\
+   - A Feature is a bundle of one or more Plug-ins and/or Fragments and associated material.\n\
+     Each Feature may be packaged as a sub-directory in a directory named "features".\n\
+     Within a Feature, files named "feature.xml" may contain a list of the names and version\n\
+     numbers of the Plug-ins and/or Fragments associated with that Feature.\n\
+   - Features may also include other Features ("Included Features"). Within a Feature, files\n\
+     named "feature.xml" may contain a list of the names and version numbers of Included Features.\n\
+\n\
+Features may also include other Features ("Included Features"). Files named\n\
+"feature.xml" may contain a list of the names and version numbers of\n\
+Included Features.\n\
+\n\
+The terms and conditions governing Plug-ins and Fragments should be\n\
+contained in files named "about.html" ("Abouts"). The terms and\n\
+conditions governing Features and Included Features should be contained\n\
+in files named "license.html" ("Feature Licenses"). Abouts and Feature\n\
+Licenses may be located in any directory of a Download or Module\n\
+including, but not limited to the following locations:\n\
+\n\
+   - The top-level (root) directory\n\
+   - Plug-in and Fragment directories\n\
+   - Inside Plug-ins and Fragments packaged as JARs\n\
+   - Sub-directories of the directory named "src" of certain Plug-ins\n\
+   - Feature directories\n\
+\n\
+Note: if a Feature made available by the Eclipse Foundation is installed using the\n\
+Eclipse Update Manager, you must agree to a license ("Feature Update\n\
+License") during the installation process. If the Feature contains\n\
+Included Features, the Feature Update License should either provide you\n\
+with the terms and conditions governing the Included Features or inform\n\
+you where you can locate them. Feature Update Licenses may be found in\n\
+the "license" property of files named "feature.properties". Such Abouts,\n\
+Feature Licenses and Feature Update Licenses contain the terms and\n\
+conditions (or references to such terms and conditions) that govern your\n\
+use of the associated Content in that directory.\n\
+\n\
+THE ABOUTS, FEATURE LICENSES AND FEATURE UPDATE LICENSES MAY REFER\n\
+TO THE EPL OR OTHER LICENSE AGREEMENTS, NOTICES OR TERMS AND CONDITIONS.\n\
+SOME OF THESE OTHER LICENSE AGREEMENTS MAY INCLUDE (BUT ARE NOT LIMITED TO):\n\

+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) 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. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
