+ There are two ways of specifying a source gamut 1) Specify a

+ colors that are up to the percentage outside the devices gamut will
+ be compressed to fit into it. The same percentage is used for
+ expansion if a saturation table is generated, or a separate
+ percentage can be specified by including both a <b>-s</b> and <b>-S</b>
+ percentage. You can optionally specify <u>both</u> and input ICC
+ profile and a general compression percentage by using the -S option
+ twice, in which case the input profile determines just the luminance
+ range mapping, with the percentage determining the gamut volume
+ compression. If a percentage compression is specified without an ICC
+ profile, then the incoming luminance range will be assumed to be
