+This extension can be used to repro infrequent crashers on an unclear url-set
+for a given domain. It follows a random link that matches a predefined pattern,
+imitating something like real user interaction on a page.
+
+Usage:
+1. Open chrome://extensions
+2. Enable developer mode
+3. Click "Load unpacked extension"
+4. Click the orange link-clicker extension button in the toolbar
+5. Set the parameters and click "Enable" to start following links on all tabs
+   open in the current window. Beware, this extension will follow arbitrary
+   links. You probably don't want to be logged in with any important account.

+Use this script to update V8 in a Node.js checkout.
+
+Requirements:
+  - Node.js checkout in which V8 should be updated.
+  - V8 checkout at the commit to which Node.js should be updated.
+
+Usage:
+  $ update_node.py <path_to_v8> <path_to_node>
+
+  This will synchronize the content of <path_to_node>/deps/v8 with <path_to_v8>,
+  and a few V8 dependencies require in Node.js. It will also update .gitignore
+  appropriately.
+
+Optional flags:
+  --gclient     Run `gclient sync` on the V8 checkout before updating.
+  --commit      Create commit with the updated V8 in the Node.js checkout.
+  --with-patch  Also include currently staged files in the V8 checkout.
