+buffer-shims
+===
+
+functions to make sure the new buffer methods work in older browsers.
+
+```js
+var bufferShim = require('buffer-shims');
+bufferShim.from('foo');
+bufferShim.alloc(9, 'cafeface', 'hex');
+bufferShim.allocUnsafe(15);
+bufferShim.allocUnsafeSlow(21);
+```
+
+should just use the original  in newer nodes and on older nodes uses fallbacks.
+
+Known Issues
+===
+- this does not patch the buffer object, only the constructor stuff
+- it's actually a polyfill
