+# 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.
