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

<usage>
    <p>Sets an environment variable, which is then passed on to CGI
    scripts and SSI pages.</p>

    <example><title>Example</title>
      SetEnv SPECIAL_PATH /foo/bin
    </example>

    <note><p>The internal environment variables set by this directive are set
    <em>after</em> most early request processing directives are run, such as access
    control and URI-to-filename mapping.  If the environment variable you're
    setting is meant as input into this early phase of processing such as the
    <directive module="mod_rewrite">RewriteRule</directive> directive, you should 
    instead set the environment variable with
    <directive module="mod_setenvif"> SetEnvIf</directive>.</p>
