+ECMAScript spec abstract operations.
+When different versions of the spec conflict, the default export will be the latest version of the abstract operation.
+All abstract operations will also be available under an `es5`/`es2015`/`es2016` entry point, and exported property, if you require a specific version.
+
+## Example
+
+```js
+var ES = require('es-abstract');
+var assert = require('assert');
+
+assert(ES.isCallable(function () {}));
+assert(!ES.isCallable(/a/g));
+```
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`
