6.8.3 Replacing Older Functions with the subprocess Module</A>

<P>
In this section, "a ==&gt; b" means that b can be used as a replacement
for a.

<P>
<span class="note"><b class="label">Note:</b>
All functions in this section fail (more or less) silently if
the executed program cannot be found; this module raises an
<tt class="exception">OSError</tt> exception.</span>

<P>
In the following examples, we assume that the subprocess module is
imported with "from subprocess import *".
