Task to automate a remote rexec session. Just like the Telnet task,
it uses nested <tt><read></tt> to indicate strings to wait for, and
<tt><write></tt> tags to specify text to send to the remote process.
<p><b>Note:</b> This task depends on external libraries not included in the Ant distribution.
See <ahref="../install.html#librarydependencies">Library Dependencies</a> for more information.</p>

<h3><aname="nested">Nested Elements</a></h3>
The input to send to the server, and responses to wait for, are
described as nested elements.
<h4>read</h4>
<p>declare (as a text child of this element) a string to wait for.
The element supports the timeout attribute, which overrides any
timeout specified for the task as a whole. It also has a <tt>string</tt>
attribute, which is an alternative to specifying the string as
a text element.
</p>
<i>It is not necessary to declare a closing <read> element like for the Telnet task. The connection is not broken until the command has completed and
the input stream (output of the command) is terminated.
</i>
<h4>write</h4>
<p>describes the text to send to the server. The <tt>echo</tt> boolean
attribute controls whether the string is echoed to the local log;
this is "true" by default
</p>
<h3>Example</h3>
A simple example of connecting to a server and running a command.
