	See conversion-examples.txt.gz on how to convert
	the PPM files produced by dcraw to other image formats.\n

	\nThe functionality of the external program 'fujiturn' was
	incorporated into dcraw and is automatically used now.\n

	\nThere's an example wrapper script included called 'dcwrap'.
	This package also includes 'dcparse', which extracts
	thumbnail images (preferably JPEGs) from any raw digital
	camera formats that have them, and shows table contents.
