+# SYNOPSIS
+#
+# AE_FEATURE(FEATURE-NAME, FEATURE-DESCRIPTION,
+# ACTION-IF-GIVEN?, ACTION-IF-NOT-GIVEN?,
+# ACTION-IF-ENABLED?, ACTION-IF-NOT-ENABLED?)
+#
+# DESCRIPTION
+#
+# AE_FEATURE is a simple wrapper for AC_ARG_ENABLE.
+#
+# FEATURE-NAME should consist only of alphanumeric characters, dashes,
+# plus signs, and dots.
+#
+# FEATURE-DESCRIPTION will be formatted with AS_HELP_STRING.
+#
+# If the user gave configure the option --enable-FEATURE or --disable-FEATURE,
+# run shell commands ACTION-IF-GIVEN. If neither option was given, run shell
+# commands ACTION-IF-NOT-GIVEN. The name feature indicates an optional
+#
+# If the feature is enabled, run shell commands ACTION-IF-ENABLED, if it is
+# disabled, run shell commands ACTION-IF-NOT-ENABLED.
+#
+# A FEATURE has 3 different states, enabled, disabled and undefined. The first
+# two are self explanatory, the third state means it's disabled by default
+# and it was not explicitly enabled or disabled by the user or by the
+# AE_FEATURE_ENABLE and AE_FEATURE_DISABLE macros.
+#
+# A feature is disabled by default, in order to change this behaviour use the
+# AE_FEATURE_DEFAULT_ENABLE and AE_FEATURE_DEFAULT_DISABLE
+# macros.
+#
+# A simple example:
+#
+# AE_FEATURE_DEFAULT_ENABLE
+# AE_FEATURE(feature_xxxxx, [turns on/off XXXXX support])
+#
+# ...
+#
+# AE_FEATURE_DEFAULT_DISABLE
+# AE_FEATURE(feature_yyyyy, [turns on/off YYYYY support])
+# AM_CONDITIONAL(YYYYY, AE_IS_FEATURE_ENABLED([feature_yyyyy]))
+#
+# AE_FEATURE_DEFAULT_ENABLE
+# AE_FEATURE(...)
+#
+# ...
+#
+# Use AE_FEATURE_ENABLE or AE_FEATURE_DISABLE in order to
+# enable or disable a specific feature.
+#
+# Another simple example:
+#
+# AS_IF([some_test_here],[AE_FEATURE_ENABLE(feature_xxxxx)],[])
+#
+# AE_FEATURE(feature_xxxxx, [turns on/off XXXXX support],
+# HAVE_XXXXX, [Define if you want XXXXX support])
+# AE_FEATURE(feature_yyyyy, [turns on/off YYYYY support],
+# HAVE_YYYYY, [Define if you want YYYYY support])
+#
+# ...
+#
+# NOTE: AE_FEATURE_ENABLE/DISABLE() must be placed first of the relative
+# AE_FEATURE() macro if you want the the proper ACTION-IF-ENABLED and
+# ACTION-IF-NOT-ENABLED to run.

+# If FLAGS-VARIABLE is not specified, the current language's flags (e.g.

+# If EXTRA-FLAGS is defined, it is added to the current language's default
