// name is the name of the function, unqouted.

// args_name is the name of the octave_value_list variable used to pass

// already defined as a macro). In that case, name is already a
// quoted string, and the internal name of the function must be passed
// too (the convention is to use a prefix of "F", so "foo" becomes "Ffoo").
