+<h3>Description</h3>
+<p>A task for sleeping a short period of time, useful when a build or deployment process requires an
+interval between tasks.</p>
+
+<h3>Parameters</h3>

+<p>The sleep time is the sum of specified values, hours, minutes seconds and milliseconds.  A
+negative value can be supplied to any of them provided the total sleep time is positive</p>
+<p>Note that sleep times are always hints to be interpreted by the OS how it feels&mdash;small times
+may either be ignored or rounded up to a minimum timeslice. Note also that the system clocks often
+have a fairly low granularity too, which complicates measuring how long a sleep actually took.</p>
+<h3>Examples</h3>
+<p>Sleep for about 10 ms.</p>
+<pre>&lt;sleep milliseconds=&quot;10&quot;/&gt;</pre>
+
+<p>Sleep for about 2 seconds.</p>
+<pre>&lt;sleep seconds=&quot;2&quot;/&gt;</pre>
+
+<p>Sleep for one hour less 59:58, or two seconds again.</p>
+<pre>&lt;sleep hours=&quot;1&quot; minutes=&quot;-59&quot; seconds=&quot;-58&quot;/&gt;</pre>
+
+<p>Sleep for no time at all. This may yield the CPU time to another thread or process.</p>
