+A function that returns the normally hidden `AsyncFunction` constructor, when available.
+
+## Getting started

+## Usage/Examples
+
+```js
+const assert = require('assert');
+const AsyncFunction = require('async-function')();
+
+const fn = new AsyncFunction('return 1');
+
+assert.equal(fn.toString(), 'async function anonymous(\n) {\nreturn 1\n}');
+
+fn().then(x => {
+    assert.equal(x, 1);
+});
+```
+
+## Tests

+
+Robustly get the [[Prototype]] of an object. Uses the best available method.
+
+## Getting started
+
+```sh
+npm install --save get-proto
+```
+
+## Usage/Examples
+
+```js
+const assert = require('assert');
+const getProto = require('get-proto');
+
+const a = { a: 1, b: 2, [Symbol.toStringTag]: 'foo' };
+const b = { c: 3, __proto__: a };
+
+assert.equal(getProto(b), a);
+assert.equal(getProto(a), Object.prototype);
+assert.equal(getProto({ __proto__: null }), null);
+```
+
+## Tests
+
+Clone the repo, `npm install`, and run `npm test`

+Determine if the JS environment has `Symbol.toStringTag` support. Supports spec, or shams.
+
+## Example
+
+```js
+var hasSymbolToStringTag = require('has-tostringtag');
+
+hasSymbolToStringTag() === true; // if the environment has native Symbol.toStringTag support. Not polyfillable, not forgeable.
+
+var hasSymbolToStringTagKinda = require('has-tostringtag/shams');
+hasSymbolToStringTagKinda() === true; // if the environment has a Symbol.toStringTag sham that mostly follows the spec.
+```
+
+## Supported Symbol shams
+ - get-own-property-symbols [npm](https://www.npmjs.com/package/get-own-property-symbols) | [github](https://github.com/WebReflection/get-own-property-symbols)
+ - core-js [npm](https://www.npmjs.com/package/core-js) | [github](https://github.com/zloirock/core-js)
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`

+
+Give a regex, get a robust predicate function that tests it against a string. This will work even if `RegExp.prototype` is altered later.
+
+## Getting started
+
+```sh
+npm install --save safe-regex-test
+```
+
+## Usage/Examples
+
+```js
+var regexTester = require('safe-regex-test');
+var assert = require('assert');
+
+var tester = regexTester('a');
+assert.ok(tester('a'));
+assert.notOk(tester('b'));
+```
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`
