124	+	Output flushing at fixed intervals may be enabled with the
125	+	.I \-x
126	+	option, which specifies the number of records
127	+	(-c accumulations) before each flush.
128	+	If the
129	+	.I \-y
130	+	option is also set, then periodic flushing is disabled and the
131	+	output size for an RGB image is the taken from the x and y dimensions.
132	+	In lieu of periodic flushing, a flush may be forced as mentioned above
133	+	by sending a sample with a zero direction vector, although you
134	+	must still send a full record of rays before output occurs.
135	+	.PP
136	+	If progress reports are desired, the
137	+	.I \-t
138	+	option specifies a time interval in seconds for reports sent to
139	+	standard error.
140	+	This requires that the number of input samples is known, meaning a
141	+	.I \-y
142	+	parameter has been specified.
