+
+Simple, cross-browser [Error](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Error) parser.
+This library parses and extracts function names, URLs, line numbers, and column numbers from the given Error's `stack` as
+an Array of [StackFrame](http://git.io/stackframe)s. 
+
+Once you have parsed out StackFrames, you can do much more interesting things. See [stacktrace-gps](http://git.io/stacktrace-gps).
+
+Note that in IE9 and earlier, `Error` objects don't have enough information to extract much of anything. In IE 10, `Error`s
+are given a `stack` once they're `throw`n.
+
+## Browser Support
+[![Sauce Test Status](https://saucelabs.com/browser-matrix/stacktracejs.svg)](https://saucelabs.com/u/stacktracejs)
+
+## Usage
+```js
+ErrorStackParser.parse(new Error('BOOM'));
+
+=> [
+        StackFrame({functionName: 'foo', args: [], fileName: 'path/to/file.js', lineNumber: 35, columnNumber: 79, isNative: false, isEval: false}),
+        StackFrame({functionName: 'Bar', fileName: 'https://cdn.somewherefast.com/utils.min.js', lineNumber: 1, columnNumber: 832, isNative: false, isEval: false, isConstructor: true}),
+        StackFrame(... and so on ...)
+   ]
+```
+
+## Installation
+```bash
+npm install error-stack-parser
+bower install error-stack-parser
+https://raw.githubusercontent.com/stacktracejs/error-stack-parser/master/dist/error-stack-parser.min.js
