-# 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 ...
