+;;; Commentary:
+;;;
+;;; Some helpers around guile-newt to draw or run generic pages. The
+;;; difference between 'draw' and 'run' terms comes from newt library. A page
+;;; is drawn when the form it contains does not expect any user
+;;; interaction. In that case, it is necessary to call (newt-refresh) to force
+;;; the page to be displayed. When a form is 'run', it is blocked waiting for
+;;; any action from the user (press a button, input some text, ...).
+;;;
+;;; Code:
+

+this page to TITLE."
