#
# SYNOPSIS
#
# AX_PROG_APACHE([version])
#
# DESCRIPTION
#
# This macro searches for an installed apache server. If nothing was
# specified when calling configure or just --with-apache, it searches in
# /usr/local/apache/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin
# The argument of --with-apache specifies the full pathname of the httpd
# argument. For instance --with-apache=/usr/sbin/httpd.
#
# If the version argument is given, AX_PROG_APACHE checks that the apache
# server is this version number or higher.
#
# If the apache server is not found, abort configuration with error
# message.
#
# It defines the symbol APACHE if the server is found.
#
# Files using apache should do the following:
#
# @APACHE@ -d /etc/httpd
#
# It defines the symbol APACHE_MODULES if a directory containing mod_env.*
# is found in the default server root directory (obtained with httpd -V).
#
# The httpd.conf file listing modules to be loaded dynamically can use
# @APACHE_MODULES@ to grab them in the appropriate sub directory. For
# instance:
#
# ...
# <IfModule mod_so.c>
# LoadModule env_module @APACHE_MODULES@/mod_env.so
# LoadModule config_log_module @APACHE_MODULES@/mod_log_config.so
# ...
