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