# DESCRIPTION
# 'yocto-layer' is the Yocto Tool that helps users create a new Yocto
# layer. Invoking it without any arguments will display help screens
# for the 'yocto-layer' command and list the available 'yocto-layer'
# subcommands. Invoking a subcommand without any arguments will
# likewise display help screens for the specified subcommand. Please
# use that interface for detailed help.
