#
# SYNOPSIS
#
# AX_CONFIG_FEATURE(FEATURE-NAME, FEATURE-DESCRIPTION, DEFINE, DEFINE-DESCRIPTION, [ACTION-IF-ENABLED [, ACTION-IF-NOT-ENABLED]])
#
# DESCRIPTION
#
# AX_CONFIG_FEATURE is a simple wrapper for AC_ARG_ENABLE, it enables the
# feature FEATURE-NAME and AC_DEFINEs the passed DEFINE, depending on the
# user choice. DESCRIPTION will be used for AC_DEFINEs. ACTION-IF-ENABLED
# and ACTION-IF-NOT-ENABLED are the actions that will be run. A feature is
# enabled by default, in order to change this behaviour use the
# AX_CONFIG_FEATURE_DEFAULT_ENABLED and AX_CONFIG_FEATURE_DEFAULT_DISABLED
# macros.
#
# A simple example:
#
# AX_CONFIG_FEATURE_DEFAULT_ENABLED
# AX_CONFIG_FEATURE(feature_xxxxx, [turns on/off XXXXX support],
# HAVE_XXXXX, [Define if you want XXXXX support])
#
# ...
#
# AX_CONFIG_FEATURE_DEFAULT_DISABLED
# AX_CONFIG_FEATURE(feature_yyyyy, [turns on/off YYYYY support],
# HAVE_YYYYY, [Define if you want YYYYY support],
# [enable_yyyyy="yes"], [enable_yyyyy="no"])
# AM_CONDITIONAL(YYYYY, [test "$enable_yyyyy" = "yes"])
#
# AX_CONFIG_FEATURE_DEFAULT_ENABLED
# AX_CONFIG_FEATURE(...)
#
# ...
#
# If you have lot of features and you want a verbose dumping of each user
# selection use AX_CONFIG_FEATURE_VERBOSE. Use AX_CONFIG_FEATURE_SILENT in
# order to remove a previously AX_CONFIG_FEATURE_VERBOSE. By default
# features are silent.
#
# Use AX_CONFIG_FEATURE_ENABLE or AX_CONFIG_FEATURE_DISABLE in order to
# enable or disable a specific feature.
#
# Another simple example:
#
# AS_IF([some_test_here],[AX_CONFIG_FEATURE_ENABLE(feature_xxxxx)],[])
#
# AX_CONFIG_FEATURE(feature_xxxxx, [turns on/off XXXXX support],
# HAVE_XXXXX, [Define if you want XXXXX support])
# AX_CONFIG_FEATURE(feature_yyyyy, [turns on/off YYYYY support],
# HAVE_YYYYY, [Define if you want YYYYY support],
# [enable_yyyyy="yes"], [enable_yyyyy="no"])
#
# ...
#
# NOTE: AX_CONFIG_FEATURE_ENABLE() must be placed first of the relative
# AX_CONFIG_FEATURE() macro ...
