DESCRIPTION will be used for AC_DEFINEs. ACTION-IF-ENABLED 14# and ACTION-IF-NOT-ENABLED are the actions that will be run. A feature is 15# enabled by default, in order to change this behaviour use the 16# AX_CONFIG_FEATURE_DEFAULT_ENABLED and AX_CONFIG_FEATURE_DEFAULT_DISABLED 17# macros. 18# 19# A simple example: 20# 21# AX_CONFIG_FEATURE_DEFAULT_ENABLED 22# AX_CONFIG_FEATURE(feature_xxxxx, [turns on/off XXXXX support], 23# HAVE_XXXXX, [Define if you want XXXXX support]) 24# 25# ... 26# 27# AX_CONFIG_FEATURE_DEFAULT_DISABLED 28# AX_CONFIG_FEATURE(feature_yyyyy, [turns on/off YYYYY support], 29# HAVE_YYYYY, [Define if you want YYYYY support], 30# [enable_yyyyy="yes"], [enable_yyyyy="no"]) 31# AM_CONDITIONAL(YYYYY, [test "$enable_yyyyy" = "yes"]) 32# 33# AX_CONFIG_FEATURE_DEFAULT_ENABLED 34# AX_CONFIG_FEATURE(...) 35# 36# ... 37# 38# If you have lot of features and you want a verbose dumping of each user 39# selection use AX_CONFIG_FEATURE_VERBOSE. Use AX_CONFIG_FEATURE_SILENT in 40# order to remove a previously AX_CONFIG_FEATURE_VERBOSE. By default 41# features are silent. 42# 43# Use AX_CONFIG_FEATURE_ENABLE or AX_CONFIG_FEATURE_DISABLE in order to 44# enable or disable a specific feature. 45# 46# Another simple example: 47# 48# AS_IF([some_test_here],[AX_CONFIG_FEATURE_ENABLE(feature_xxxxx)],[]) 49# 50# AX_CONFIG_FEATURE(feature_xxxxx, [turns on/off XXXXX support], 51# HAVE_XXXXX, [Define if you want XXXXX support]) 52# AX_CONFIG_FEATURE(feature_yyyyy, [turns on/off YYYYY support], 53# HAVE_YYYYY, [Define if you want YYYYY support], 54# [enable_yyyyy="yes"], [enable_yyyyy="no"]) 55# 56# ... 57# 58# NOTE: AX_CONFIG_FEATURE_ENABLE() must be placed first of the relative 59# AX_CONFIG_FEATURE() macro ... 60# 61# LICENSE 62# 63# Copyright (c) 2008 Francesco Salvestrini <salvestrini@users.sourceforge.net> 64# 65# This program is free software; you can redistribute it and/or modify it 66# under the terms of the GNU General Public License as published by the 67# Free Software Foundation; either version 2 of the License, or (at your 68# option) any later version. 69# 70# This program is distributed in the hope that it will be useful, but 71# WITHOUT ANY WARRANTY; without even the implied warranty of 72# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
