<h3>Summary</h3>

    <p>This module allows for control of the environment that will
    be provided to CGI scripts and SSI pages. Environment variables
    may be passed from the shell which invoked the <code class="program"><a href="../programs/httpd.html">httpd</a></code>
    process. Alternatively, environment variables may be set or unset within
    the configuration process.</p>
