Basically the choice will be this alist: '((interactive . x) (non-interactive . y)) where x and y can be: 'ask => prompt y/n/Y (permanent)/N (permanent)/inspect 'maybe-reject => goes through the acceptance function and rejects if it fails nil => always reject unknown t => always accept, good for testing but discouraged otherwise The symbols may evolve to specify the acceptance function inline. The default will probably be '((interactive ask) (non-interactive maybe-reject)) I hope that's helpful :) Ted
