dnl                   DISABLE-BY-DEFAULT, ACTION-IF-USE, ACTION-IF-NOTUSE)
dnl
dnl This macro adds a command line argument to enable the user to enable
dnl or disable a feature, and if the feature is enabled, performs a supplied
dnl test to check if the feature is available.
dnl
dnl The test should define HAVE_<FEATURE-NAME> to "yes" or "no" depending
dnl on whether the feature is available.
dnl
dnl The macro will set USE_<<FEATURE-NAME> to "yes" or "no" depending on
dnl whether the feature is to be used.
dnl
dnl The macro will call AM_CONDITIONAL(USE_<<FEATURE-NAME>, ...) to allow
dnl the feature to control what is built in Makefile.ams.  If you want
dnl additional actions resulting from the test, you can add them with the
dnl ACTION-IF-USE and ACTION-IF-NOTUSE parameters.
dnl 
dnl FEATURE-NAME        is the name of the feature, and should be in
dnl                     purely upper case characters.
dnl FEATURE-DESCRIPTION is used to describe the feature in help text for
dnl                     the command line argument.
dnl DEPENDENT-PLUGINS   lists any plugins which depend on this feature.
dnl TEST-FOR-FEATURE    is a test which sets HAVE_<FEATURE-NAME> to "yes"
dnl                     or "no" depending on whether the feature is
dnl                     available.
dnl DISABLE-BY-DEFAULT  if "disabled", the feature is disabled by default,
dnl                     if any other value, the feature is enabled by default.
dnl ACTION-IF-USE       any extra actions to perform if the feature is to be
dnl                     used.
dnl ACTION-IF-NOTUSE    any extra actions to perform if the feature is not to
dnl                     be used.
