+### Event: 'reset'
+
+`function (context) {}`
+
+Emitted when the REPL's context is reset. This happens when you type `.clear`.
+If you start the repl with `{ useGlobal: true }` then this event will never
+be emitted.
+
+Example of listening for `reset`:
+
+ // Extend the initial repl context.
+ r = repl.start({ options ... });
+ someExtension.extend(r.context);
+
+ // When a new context is created extend it as well.
+ r.on('reset', function (context) {
+ console.log('repl has a new context');
+ someExtension.extend(context);
+ });
+
