+### Esrecurse [![Build Status](https://secure.travis-ci.org/estools/esrecurse.png)](http://travis-ci.org/estools/esrecurse)
+
+Esrecurse ([esrecurse](http://github.com/estools/esrecurse)) is
+[ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+recursive traversing functionality.
+
+### Example Usage
+
+The following code will output all variables declared at the root of a file.
+
+```javascript
+esrecurse.visit(ast, {
+    XXXStatement: function (node) {
+        this.visit(node.left);
+        // do something...
+        this.visit(node.right);
+    }
+});
+```
+
+We can use `Visitor` instance.
+
+```javascript
+var visitor = new esrecurse.Visitor({
+    XXXStatement: function (node) {
+        this.visit(node.left);
+        // do something...
+        this.visit(node.right);
+    }
+});
+
+visitor.visit(ast);
+```
+
+We can inherit `Visitor` instance easily.
+
+```javascript
+function DerivedVisitor() {
+    esrecurse.Visitor.call(/* this for constructor */  this  /* visitor object automatically becomes this. */);
+}
+util.inherits(DerivedVisitor, esrecurse.Visitor);
+DerivedVisitor.prototype.XXXStatement = function (node) {
+    this.visit(node.left);
+    // do something...
+    this.visit(node.right);
+};
+```
+
+And you can invoke default visiting operation inside custom visit operation.
+
+```javascript
+function DerivedVisitor() {
+    esrecurse.Visitor.call(/* this for constructor */  this  /* visitor object automatically becomes this. */);
+}
+util.inherits(DerivedVisitor, esrecurse.Visitor);
+DerivedVisitor.prototype.XXXStatement = function (node) {
+    // do something...
+    this.visitChildren(node);
+};
+```
