<code>AC_PROG_HTTPD</code>
</p>
<h2>
Description
</h2>
<div class="indent">
<p>
Check for Apache's 'httpd', let script continue if exists & works, pops
up error message if not.
</p>
<p>
Testing of functionality is by checking its compile settings
</p>
<p>
Besides checking existence, this macro also set these environment variables
upon completion:
</p>
<pre>
HTTPD = which httpd
HTTPD_ROOT = Apache's root directory, specified when compiled / run with -d option
HTTPD_SERVER_ROOT = Directory for Apache's essential files, e.g. access logs / error logs / modules / scripts.
HTTPD_SERVER_CONFIG_FILE = Full-path of the 'httpd.conf' file
HTTPD_USER = Which user that httpd runs as
HTTPD_GROUP = Which group that httpd runs as
HTTPD_DOC_HOME = Document directory, taken as the first DocumentRoot path found in httpd.conf
HTTPD_SCRIPT_HOME = CGI script directory, taken as the first ScriptAlias path found in httpd.conf
