+<dd>
+<p>If you are developing in Eclipse with ADT, note that SDK Tools r6 is
+designed for use with ADT 0.9.7 and later. After installing SDK Tools r6, we
+highly recommend updating your ADT Plugin to 0.9.7.</p>
+</dd>
+
+<dt>Library projects:</dt>
+<dd>
+<p>The SDK Tools now support 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/other-ide.html#libraryProject">Developing 
+in Other IDEs</a> document.</p>
+<p>If you are developing in Eclipse, <a href="eclipse-adt.html">ADT 0.9.7</a>
+provides the equivalent library project support.</p>
