<p>This function can only be successfully called at the client
machine. <var>commands</var> must be a string containing Octave commands
suitable for execution with Octaves <code>eval()</code> function. See
<code>pconnect</code> for a description of the <var>connections</var>
variable. <var>connections</var> can contain all connections of the
network, a subset of them, or a single connection. The local machine
(client), if contained in <var>connections</var>, is
ignored. <var>commands</var> is executed in the same way at each specified
machine.
