     *     Otherwise:
     *      If '-x, --xxx', `commander.xxx` can only be true/false, even if '--xxx yyy' input.
     *      If '-x, --xxx <some>', the 'some' string is required, or otherwise error will be thrown.
     *      If '-x, --xxx [some]', the 'some' string is optional, that is, `commander.xxx` can be boolean or string.
     * (2) `node ./build/build.js --help` will print helper info and exit.
