<H2>Summary</H2>
<!-- XXX: Should mention mod_setenvif and the effect of suexec -->
<p>This module allows Apache's CGI and SSI environment to inherit
environment variables from the shell which invoked the httpd process.
CERN web-servers are able to do this, so this module is especially
useful to web-admins who wish to migrate from CERN to Apache without
rewriting all their scripts</p>
