+#
+# VIEWER is the program used to display individual sections
+#
+# RETURNTOMENU=YES prevents another prompt being given after displaying
+# each section, causing instead an immediate return to contents page. It
+# should be `YES' if VIEWER is a program that pauses for input at end of
+# file, `NO' if VIEWER is a program that quits silently at end of file.
