+        This could be used for different purposes:

+      	<li>You could use a target from a remote location (e.g. github-repository using http-protocol) in your local IDE.</li>
+      	<li>You could use a target deployed at a maven repository using the mvn:&lt;groupid&gt;:&lt;artifactid&gt;:&lt;version&gt; (this requires m2eclipse with PDE integration)</li>
+      	<li>You could extend an existing local target using eclipse-variables</li>
