+<p>The ADT Plugin now supports the use of <em>library projects</em> during
+development, a capability that lets you store shared Android application
+code and resources in a separate development project. You can then reference the
+library project from other Android projects and, at build time, the tools
+compile the shared code and resources as part of the dependent applications.
+More information about this feature is available in the <a
+href="{@docRoot}guide/developing/eclipse-adt.html#libraryProject">Developing 
+in Eclipse with ADT</a> document. </p>
+<p>If you are not developing in Eclipse, <a 
+href="tools-notes.html">SDK Tools r6</a> provides the equivalent library 
+project support through the Ant build system.</p>
