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 be used. For example, './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.
