Examples:

To color correct from scanner to sRGB:
	jpgicc -iscanner.icm in.jpg out.jpg
To convert from monitor1 to monitor2:
	jpgicc -imon1.icm -omon2.icm in.jpg out.jpg
To make a CMYK separation:
	jpgicc -oprinter.icm inrgb.jpg outcmyk.jpg
To recover sRGB from a CMYK separation:
	jpgicc -iprinter.icm incmyk.jpg outrgb.jpg
To convert from CIELab ITU/Fax JPEG to sRGB
