# DESCRIPTION
# 'yocto-kernel' is the Yocto BSP Tool that helps users manage kernel
# config options and patches for a Yocto BSP. Invoking it without any
# arguments will display help screens for the 'yocto-kernel' command
# and list the available 'yocto-kernel' subcommands. Invoking a
# subcommand without any arguments will likewise display help screens
# for the specified subcommand. Please use that interface for
# detailed help.
