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