<h2><a name="echo">Echo</a></h2>
<h3>Description</h3>
<p>Echoes a message to the current loggers and listeners which
means <tt>System.out</tt> unless overridden. A <tt>level</tt>
can be specified, which controls at what logging level the message is
filtered at. 
<p> 
The task can also echo to a file, in which case the option to append rather
than overwrite the file is available, and the <tt>level</tt> option is 
ignored</p>

has been included in the text.
