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