+.SH AGENDA MODE JSON OUTPUT
+.PP
+If you supply the \fB\-\-json\fR argument, then Remind outputs JSON
+instead of the normal text output.  The JSON output consists of
+a single JSON array of zero or more objects.  There are three
+possible types of objects in the array:
+.TP
+.B banner
+The \fBbanner\fR object, if present, will be the first object in the array.
+There will be at most one \fBbanner\fR object.  It contains a single
+key, \fBbanner\fR, whose value is the banner that \fBRemind\fR would normally
+print in Agenda Mode.
+.TP
+.B noreminders
+The \fBnoreminders\fR object, if present, will be the final object in the
+array.  There will be at most one \fBnoreminders\fR object.  It contains
+a single keym, \fBnoreminders\fR, whose value is the phrase "No reminders.",
+possibly localized into a different language.
+.TP
+.B event
+All other objects in the array are \fBevent\fR objects.  They are JSON
+objects that contain all of the keys described in the \fBrem2ps\fR(1)
+man page section "CALENDAR ENTRIES".  However, the \fBcalendar_body\fR,
+\fBplain_body\fR and \fBraw_body\fR keys will not be present.
