+
+An Object.assign shim. Invoke its "shim" method to shim Object.assign if it is unavailable.
+
+This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES3-supported environment and complies with the [spec](http://www.ecma-international.org/ecma-262/6.0/#sec-object.assign). In an ES6 environment, it will also work properly with `Symbol`s.
+
+Takes a minimum of 2 arguments: `target` and `source`.
+Takes a variable sized list of source arguments - at least 1, as many as you want.
+Throws a TypeError if the `target` argument is `null` or `undefined`.
+
+Most common usage:
+```js
+var assign = require('object.assign').getPolyfill(); // returns native method if compliant
+	/* or */
+var assign = require('object.assign/polyfill')(); // returns native method if compliant
+```
+
+## Example
+
+```js
+var assert = require('assert');
+
+// Multiple sources!
+var target = { a: true };
+var source1 = { b: true };
+var source2 = { c: true };
+var sourceN = { n: true };
+
+var expected = {
+	a: true,
+	b: true,
+	c: true,
+	n: true
+};
+
+assign(target, source1, source2, sourceN);
+assert.deepEqual(target, expected); // AWESOME!
+```
+
+```js
+var target = {
+	a: true,
+	b: true,
+	c: true
+};
+var source1 = {
+	c: false,
+	d: false
+};
+var sourceN = {
+	e: false
+};
+
+var assigned = assign(target, source1, sourceN);
+assert.equal(target, assigned); // returns the target object
+assert.deepEqual(assigned, {
+	a: true,
+	b: true,
+	c: false,
+	d: false,
+	e: false
+});
+```
+
+```js
+/* when Object.assign is not present */
+delete Object.assign;
+var shimmedAssign = require('object.assign').shim();
+	/* or */
+var shimmedAssign = require('object.assign/shim')();
+
+assert.equal(shimmedAssign, assign);
+
+var target = {
+	a: true,
+	b: true,
+	c: true
+};
+var source = {
+	c: false,
+	d: false,
+	e: false
+};
+
+var assigned = assign(target, source);
+assert.deepEqual(Object.assign(target, source), assign(target, source));
+```
+
+```js
+/* when Object.assign is present */
+var shimmedAssign = require('object.assign').shim();
+assert.equal(shimmedAssign, Object.assign);
+
+var target = {
+	a: true,
+	b: true,
+	c: true
+};
+var source = {
+	c: false,
+	d: false,
+	e: false
+};
+
+assert.deepEqual(Object.assign(target, source), assign(target, source));
+```
