+# 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.
