+# 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 ...
