+# name
+
+  Generic basic auth Authorization header field parser for whatever.
+
+## Installation
+
+```
+$ npm install basic-auth
+```
+
+## Example
+
+  Pass a node request or koa Context object to the module exported. If
+  parsing fails `undefined` is returned, otherwise an object with
+  `.name` and `.pass`.
+
+```js
+var auth = require('basic-auth');
+var user = auth(req);
+// => { name: 'something', pass: 'whatever' }
+
+```
