+<h1> The <tt>unexport</tt> program </h1>
+
+<p>
+<tt>unexport</tt> removes a variable from the environment, then
+executes a program.
+</p>
+
+<h2> Interface </h2>
+
+<pre>
+     unexport <em>var</em> <em>prog...</em>
+</pre>
+
+<p>
+<tt>unexport</tt> removes the <em>var</em> variable from the
+environment, then execs into <em>prog</em> with
+its arguments.
+</p>
+
+<h2> Notes </h2>
+
+<ul>
+ <li> Unsetting <em>var</em> is quite different from setting it to an
+empty value. Shell scripts usually won't make the distinction;
+execline does. </li>
+</ul>
