<title>Utility Programs</title>

<para>
The <application>Select</application> distribution includes some utility programs.
</para>


<sect1>
<title>select_analysis</title>

<para>

<title>pifiled</title>

<para>
<application>pifiled</application> is a daemon which imitates the behaviour of <application>selectd</application>, but runs <application>ifile</application> as a back-end
<footnote><para>It is even possible to run <application>select_ifile</application> as a back-end if you make <application>select_ifile</application> and <application>selectd</application> use another socket address than the one <application>pifiled</application> uses</para></footnote>.
</para>

<para>
This makes it possible to run <application>Select</application> clients against the <application>ifile</application> database. This is useful for testing purposes, comparing the performance of <application>ifile</application> and <application>Select</application> using <application>select_test</application>. Using this for other purposes is discouraged, as it involves unnecessary overhead.
