<h1> The <tt>seekablepipe</tt> program </h1>

<tt>seekablepipe</tt> turns the reading end of a pipe into a seekable
file descriptor, using a temporary file.

<h2> Interface </h2>

<pre>
     <em>writer</em> | seekablepipe <em>tmpfile reader [ args ... ]</em>
</pre>

<p>
<tt>seekablepipe</tt> writes <em>writer</em>'s output to <em>tmpfile</em>,
which is unlinked as soon as it is created. Then it execs into
<em>reader</em>, reading from a file descriptor on <em>tmpfile</em>.
