+## The @var{TITLE} can be used optionally to decorate the dialog caption.
+## The string @var{DEFAULT} identifies the default button, 
+## which is activated by pressing the ENTER key.
+## It must match one of the strings given in @var{BTN1}, @var{BTN2} or @var{BTN3}.
+##
+## If only @var{MESSAGE} and @var{TITLE} are specified, three buttons with
+## the default captions "Yes", "No", "Cancel" are used.

+## If only two button captions @var{BTN1} and @var{BTN2} are specified, 
+## the dialog will have only these two buttons.
