31		.I Rcomb
#	Line 60 | Line 60 | A single concatenation matrix may be applied after ele
60		using the
61		.I \-m
62		option.
63	+	If the option is given as
64	+	.I \-mt
65	+	then the concatenation matrix will be transposed before it is applied.
66		Matrix concatenation will happen before or after any trailing
67		operations, depending on relative command line placement.
68		.PP
#	Line 339 | Line 342 | is not supported in
342		.I rcomb,
343		and should instead be handled by
344		.I pfilt(1).
345	+	.PP
346	+	Similar to
347	+	.I rmtxop,
348	+	all calculations are peformed internally using 32-bit floating-point,
349	+	so there is little benefit in either reading or writing 64-bit double
350	+	data.
351	+	This may be overridden at compile time using the macro
352	+	"-DDTrmx_native=DTdouble".
