usage: cloudformation [-m|--minify] <path>
    <path> should point to the TypeScript file containing entrypoint of the CloudFormation definition

options:
    -m, --minify    Minify JSON output, default: false
    -h, --help      Show the help menu (this one)
    -v, --version   Show the version of the cli and the versions of schemas used
