+// This WebUI page displays the status of the renderer sandbox on Linux and
+// Android. The two OSes share the same basic page, but the data reported are
+// obtained from different places:
+//    - On Linux, this object in the browser queries the renderer ZygoteHost
+//      to get the sandbox status of the renderers. The data are then specified
+//      as loadTimeData on the WebUI Page.
+//    - On Android, this object sends an IPC message to the
+//      SandboxStatusExtension in the renderer, which installs a JavaScript
+//      function on the web page to return the current sandbox status.
