+[ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+scope analyzer extracted from [esmangle project](http://github.com/estools/esmangle).
+
+[![Build Status](https://travis-ci.org/estools/escope.png?branch=master)](https://travis-ci.org/estools/escope)
+
+### Example
+
+```js
+var escope = require('escope');
+var esprima = require('esprima');
+var estraverse = require('estraverse');
+
+var ast = esprima.parse(code);
+var scopeManager = escope.analyze(ast);
+
+var currentScope = scopeManager.acquire(ast);   // global scope
+
+estraverse.traverse(ast, {
+    enter: function(node, parent) {
+        // do stuff
+        
+        if (/Function/.test(node.type)) {
+            currentScope = scopeManager.acquire(node);  // get current function scope
+        }
+    },
+    leave: function(node, parent) {
+        if (/Function/.test(node.type)) {
+            currentScope = currentScope.upper;  // set to parent scope
+        }
+        
+        // do stuff
+    }
+});
