The Apache::httpd_conf module will generate a tiny httpd.conf file, which pulls itself back in via a <Perl>section. Any additional arguments passed to the write( ) method will be added to the generated httpd.conf file and will override those defaults set in the <Perl>section. This module is handy mostly for starting httpd servers to test mod_perl scripts and modules.
Supplied with the mod_perl distribution. See the module manpage for more information.
