# 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.
