+/**
+ * ### BDD Style Introduction
+ *
+ * The BDD style is exposed through `expect` or `should` interfaces. In both
+ * scenarios, you chain together natural language assertions.
+ *
+ *      // expect
+ *      var expect = require('chai').expect;
+ *      expect(foo).to.equal('bar');
+ *
+ *      // should
+ *      var should = require('chai').should();
+ *      foo.should.equal('bar');
+ *
+ * #### Differences
+ *
+ * The `expect` interface provides a function as a starting point for chaining
+ * your language assertions. It works on node.js and in all browsers.
+ *
+ * The `should` interface extends `Object.prototype` to provide a single getter as
+ * the starting point for your language assertions. It works on node.js and in
+ * all browsers except Internet Explorer.
+ *
+ * #### Configuration
+ *
+ * By default, Chai does not show stack traces upon an AssertionError. This can
+ * be changed by modifying the `includeStack` parameter for chai.Assertion. For example:
+ *
+ *      var chai = require('chai');
+ *      chai.Assertion.includeStack = true; // defaults to false

+/**
+ * ### TDD Style Introduction
+ *
+ * The TDD style is exposed through `assert` interfaces. This provides
+ * the classic assert.`test` notation, similiar to that packaged with
+ * node.js. This assert module, however, provides several additional
+ * tests and is browser compatible.
+ *

+ *      var assert = require('chai').assert;
+ *        , foo = 'bar';
+ *
+ *      assert.typeOf(foo, 'string');
+ *      assert.equal(foo, 'bar');
+ *
+ * #### Configuration
+ *
+ * By default, Chai does not show stack traces upon an AssertionError. This can
+ * be changed by modifying the `includeStack` parameter for chai.Assertion. For example:
+ *
+ *      var chai = require('chai');
+ *      chai.Assertion.includeStack = true; // defaults to false
