Hi! You guys spelled animal wrong in the flags.defineStringList() JSDoc. You spelled it "anmial". Context:

/**
 * Defines a string list flag.  e.g. --anmial=frog,bat,chicken 
 * @param {string} name The flag name, should be [a-zA-Z0-9]+.
 * @param {!Array.<string>=} opt_default The default value, should the flag not
 *     be explicitly specified.
 * @param {string=} opt_description Optional description to use in help text.
 * @return {!StringListFlag} The flag object.
 */

Shouldn't take you long to fix it. I personally don't care, just wanted to point this out to you. Thanks for making such a useful library!

Edit: Formatted code wrong
