+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.
