<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 httpd process.
    Alternatively, environment variables may be set or unset within
    the configuration process.</p>
