DESCRIPTION

'yocto-bsp' is the Yocto BSP Tool that helps users create a new

Yocto BSP. Invoking it without any arguments will display help

screens for the 'yocto-bsp' command and list the available

'yocto-bsp' subcommands. Invoking a subcommand without any

arguments will likewise display help screens for the specified

subcommand. Please use that interface for detailed help.
