DESCRIPTION 'wic' is the OpenEmbedded Image Creator that users can

use to generate bootable images. Invoking it without any arguments

will display help screens for the 'wic' command and list the

available 'wic' subcommands. Invoking a subcommand without any

arguments will likewise display help screens for the specified

subcommand. Please use that interface for detailed help.
