# 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.
