The "top level" postal object effectively provides a namespace for postal's facilities.

• The standard client (non-AMD) scenarios, the postal object is attached to the window.
• The postal module (whether AMD, CommonJS or plain browser global) returns the postal object (and you can do with it what you need from there).
• Older versions of postal had a CommonJS wrapper which returned a factory method - this is no longer the case.

CommonJS usage example:

// in node.js
var postal = require('postal');
