+<p>Vtune offers an API to <em>resume</em> and <em>pause</em> the profile collection from within
+the profilee itself.  This can be helpful if either only a certain phase should
+be profiled or some phase should be skipped.</p>
+<p>The following gives an example where only one phase in the program is profiled.
+The program makes calls to the vtune API to resume and pause the collection,
+while vtune is invoked with <code>-start-paused</code> to pause profiling initially.</p>
