title: Can somebody explain the eclipse.p2.profile
body: <p>I'm organizing a build of an Eclipse RCP.</p>
  
  <p>Using the <code>p2-director</code>, one property is the <code>profile</code>. The Eclipse <a href="http://help.eclipse.org/galileo/index.jsp?topic=/org.eclipse.platform.doc.isv/guide/p2_director.html" rel="nofollow noreferrer">documentation</a> only states the below explanation, which isn't that clear in my view.</p>
  
  <blockquote>
    <p>-profile: the profile id containing the description of the targeted product. This ID is is defined by the eclipse.p2.profile property
    contained in the config.ini of the targeted product. For the Eclipse
    SDK the ID is "SDKProfile"</p>
  </blockquote>
  
  <p>So my question is this:</p>
  
  <p>What is the profile used for, what does it describes and how can I ensure I use it properly?</p>
  
  <p>Does anybody have a better explanation or a link to a proper documentation?</p>
