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 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.
