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.
