	USAGE:	./download <PROGRAM> <OPTIONS>

	possible values for 'program':
	$(listprograms)

	Example:	./download flashrom
	Example:	./download coreboot

	Some program options allow for additional parameters:
	Example:	./download coreboot default
	Example:	./download coreboot x60

	Each program download script should work without extra paramaters, but
	they can use them. For instance, './download coreboot' will download all
	coreboot trees by default, but './download coreboot x60' will only download
	the coreboot tree required for the target: x60

	Each program download script should also accept the --help parameter to
	display the usage of the script.
	
	Refer to the documentation for more information.
