7# DESCRIPTION 'wic' is the OpenEmbedded Image Creator that users can
8# use to generate bootable images. Invoking it without any arguments
9# will display help screens for the 'wic' command and list the
10# available 'wic' subcommands. Invoking a subcommand without any
11# arguments will likewise display help screens for the specified
12# subcommand. Please use that interface for detailed help.
