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