-// A class invoked by Plugin to handle PNaCl client-side translation.
-// Usage:
-// (1) Invoke the factory method, e.g.,
-//     PnaclCoordinator* coord = BitcodeToNative(plugin,
-//                                               "http://foo.com/my.pexe",
-//                                               pnacl_options,
-//                                               TranslateNotifyCallback);
-// (2) TranslateNotifyCallback gets invoked when translation is complete.
-//     If the translation was successful, the pp_error argument is PP_OK.
-//     Other values indicate errors.
-// (3) After finish_callback runs, get the file descriptor of the translated
-//     nexe, e.g.,
-//     fd = coord->ReleaseTranslatedFD();
-// (4) Load the nexe from "fd".
-// (5) delete coord.
-//
-// Translation proceeds in two steps:
-// (1) llc translates the bitcode in pexe_url_ to an object in obj_file_.
-// (2) ld links the object code in obj_file_ and produces a nexe in nexe_file_.
