47   in the appropriate place on the command line.

101   Note that the number of coefficients must be an even multiple of the number

126 > option is given, the output will be written as a RGBE or XYZE picture.
127   Note that conversion from a float or RGBE color space applies a conversion
128   of 179 lumens/watt (for CIE or melanopic output) or 412 (for scotopic output),
129   and the reverse happens for conversion from XYZE input to RGB or RGBE output.
130 + Lower case versions of all these components are also supported, the only
131 + difference is that the aforementioned efficacy factors
132 + will be left out of the conversion.
133   .PP
134 + If a matrix or picture file path is given to the
135 + .I \-c
136 + option, then the color space of that file will be used, instead.
137 + .PP
138 + The
139 + .I \-C
140 + option takes either a symbolic color space or an input file, and will be
141 + applied to all subsequent matrices that do not have their own associated

143 + option.
144 + .PP
145   Additionally, the
146   .I \-s
147   option applies the given scalar factor(s) to the elements of the matrix.

205   Results are sent to the standard output.

209   option may be used to explicitly output components
210   as ASCII (-fa), binary doubles (-fd), floats (-ff), or common-exponent
211   colors/spectra (-fc).
212 < In the latter case, the actual matrix dimensions are written in the resolution

214   Also, matrix results will be written as standard

216   or three components.
