-// There are two phases of setup. Both are done in an instance running from a
-// temp location.
-//  1) Copy the Google Update files to the install location.
-//  2) Do everything else to install Google Update.
-//   * Executed by SetupGoogleUpdate().
-//
-//  Uninstall() undoes both phases of setup.
-//  All methods assume the instance is running with the correct permissions.
