#!/usr/bin/env python3

Generate an auto.conf and associated other config files for a given autobuilder configuration

Called with $1 - The 'nightly' target the autobuilder is running

$2 - The autobuilder step number (a given target can run multiple steps with different configurations)

$3 - The target build directory to configure

$4 - The poky branch name the build is running on

Check if config contains all the listed params

Check if a config boolean is set

Run a command, trigger a traceback with command output if it fails
