Questions (for new typings):

• [x] Does the README explain the purpose of the typings and have a link to the JavaScript project?
• [x] Do the typings follow the source structure (e.g. index.js <-> index.d.ts)?
• [x] Are they external or global modules according the source (e.g. see README sources)?

This typing need Typescript 2 because export type CommandsOptions = string | Array<string | null>; (support strictNullChecks).
