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.
