# 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.
