+# SYNOPSIS
+#
+#   AX_PROG_HTTPD
+#
+# DESCRIPTION
+#
+#   Check for Apache's 'httpd', let script continue if exists & works, pops
+#   up error message if not.
+#
+#   Testing of functionality is by checking its compile settings
+#
+#   Besides checking existence, this macro also set these environment
+#   variables upon completion:
+#
+#       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
