+   For purposes of the EPL, &quot;Program&quot; will mean the Content.</p> 
+ 
+<p>Content includes, but is not limited to, source code, object code, documentation and other files maintained in the Eclipse Foundation source code
+   repository (&quot;Repository&quot;) in software modules (&quot;Modules&quot;) and made available as downloadable archives (&quot;Downloads&quot;).</p> 
+ 
+<ul> 
+       <li>Content may be structured and packaged into modules to facilitate delivering, extending, and upgrading the Content.  Typical modules may include plug-ins (&quot;Plug-ins&quot;), plug-in fragments (&quot;Fragments&quot;), and features (&quot;Features&quot;).</li> 
+       <li>Each Plug-in or Fragment may be packaged as a sub-directory or JAR (Java&trade; ARchive) in a directory named &quot;plugins&quot;.</li> 
+       <li>A Feature is a bundle of one or more Plug-ins and/or Fragments and associated material.  Each Feature may be packaged as a sub-directory in a directory named &quot;features&quot;.  Within a Feature, files named &quot;feature.xml&quot; may contain a list of the names and version numbers of the Plug-ins

+       <li>Features may also include other Features (&quot;Included Features&quot;). Within a Feature, files named &quot;feature.xml&quot; may contain a list of the names and version numbers of Included Features.</li> 
+</ul> 
+ 
+<p>The terms and conditions governing Plug-ins and Fragments should be contained in files named &quot;about.html&quot; (&quot;Abouts&quot;). The terms and conditions governing Features and

+including, but not limited to the following locations:</p> 
+ 
+<ul> 
+       <li>The top-level (root) directory</li>

+</ul> 
+ 
+<p>Note: if a Feature made available by the Eclipse Foundation is installed using the Provisioning Technology (as defined below), you must agree to a license (&quot;Feature Update License&quot;) during the
+installation process.  If the Feature contains Included Features, the Feature Update License should either provide you with the terms and conditions governing the Included Features or
+inform you where you can locate them.  Feature Update Licenses may be found in the &quot;license&quot; property of files named &quot;feature.properties&quot; found within a Feature.
+Such Abouts, Feature Licenses, and Feature Update Licenses contain the terms and conditions (or references to such terms and conditions) that govern your use of the associated Content in

+OTHER LICENSE AGREEMENTS MAY INCLUDE (BUT ARE NOT LIMITED TO):</p>

+<h3>Use of Provisioning Technology</h3> 
+ 
+<p>The Eclipse Foundation makes available provisioning software, examples of which include, but are not limited to, p2 and the Eclipse
+   Update Manager (&quot;Provisioning Technology&quot;) for the purpose of allowing users to install software, documentation, information and/or
+   other materials (collectively &quot;Installable Software&quot;). This capability is provided with the intent of allowing such users to
+   install, extend and update Eclipse-based products. Information about packaging Installable Software is available at <a 
+       href="http://eclipse.org/equinox/p2/repository_packaging.html">http://eclipse.org/equinox/p2/repository_packaging.html</a> 
+   (&quot;Specification&quot;).</p> 
+ 
+<p>You may use Provisioning Technology to allow other parties to install Installable Software. You shall be responsible for enabling the
+   applicable license agreements relating to the Installable Software to be presented to, and accepted by, the users of the Provisioning Technology
+   in accordance with the Specification. By using Provisioning Technology in such a manner and making it available in accordance with the
+   Specification, you further acknowledge your agreement to, and the acquisition of all necessary rights to permit the following:</p> 
+ 
+<ol> 
+       <li>A series of actions may occur (&quot;Provisioning Process&quot;) in which a user may execute the Provisioning Technology
+       on a machine (&quot;Target Machine&quot;) with the intent of installing, extending or updating the functionality of an Eclipse-based
+       product.</li> 
+       <li>During the Provisioning Process, the Provisioning Technology may cause third party Installable Software or a portion thereof to be
+       accessed and copied to the Target Machine.</li> 
+       <li>Pursuant to the Specification, you will provide to the user the terms and conditions that govern the use of the Installable
+       Software (&quot;Installable Software Agreement&quot;) and such Installable Software Agreement shall be accessed from the Target
+       Machine in accordance with the Specification. Such Installable Software Agreement must inform the user of the terms and conditions that govern
+       the Installable Software and must solicit acceptance by the end user in the manner prescribed in such Installable Software Agreement. Upon such
+       indication of agreement by the user, the provisioning Technology will complete installation of the Installable Software.</li> 
+</ol> 
+ 
+<h3>Cryptography</h3> 
+ 
+<p>Content may contain encryption software. The country in which you are currently may have restrictions on the import, possession, and use, and/or re-export to
+   another country, of encryption software. BEFORE using any encryption software, please check the country's laws, regulations and policies concerning the import,
+   possession, or use, and re-export of encryption software, to see if this is permitted.</p>
