;; This file is part of GNU Emacs.
;; least, you will want to turn off the keystroke thresholds and rest
;; interval tracking.
-;; This program has no hope of working in Emacs 18, and it doesn't
-;; presently work in Lucid Emacs/XEmacs because the timer.el package is
-;; entirely different.
+;; If you prefer not to be queried about taking breaks, but instead just
+;; want to be reminded, do the following:
+;;
+;; (setq type-break-query-mode nil)
+;;
+;; Or call the command `type-break-query-mode' with a negative prefix
+;; argument.
+
+;; If you find echo area messages annoying and would prefer to see messages
+;; in the mode line instead, do M-x type-break-mode-line-message-mode
+;; or set the variable of the same name to `t'.
;; This program can truly cons up a storm because of all the calls to
;; `current-time' (which always returns 3 fresh conses). I'm dismayed by
;; this, but I think the health of my hands is far more important than a
;; few pages of virtual memory.
+;; This program has no hope of working in Emacs 18.
+
;; This package was inspired by Roland McGrath's hanoi-break.el.
