+   This file is the interface to the rest of rc for any locally
+   defined addon builtins.  By default there are none.
+   The interface consists of the following macro.
+  
+   ADDONS	A comma-separated list of pairs of function pointers
+		and string literals.
+  
+   The addon functions must also have proper prototypes in this file.
+   The builtins all have the form:
+  
+	void b_NAME(char **av);
+  
+   Builtins report their exit status using set(TRUE) or set(FALSE).
+  
+   Example:
+  
+	#define ADDONS	{ b_test, "test" },
+	extern void b_test(char **av);
