   Contains tracing options:
   Tracing options control which core tracing systems should be enabled.
 
   This simply turns on those systems. If those systems have additional options,
   e.g. what to trace, then they are typically configured by adding
   categories to the TracingCategoryFilter.
 
   Options:
-      enable_chrome_trace: a boolean that specifies whether to enable
-          chrome tracing.
+      enable_chrome_trace: a boolean that specifies whether to enable chrome
+          tracing.
       enable_platform_display_trace: a boolean that specifies whether to
           platform display tracing.
       enable_android_graphics_memtrack: a boolean that specifies whether
           to enable the memtrack_helper daemon to track graphics memory on
           Android (see goo.gl/4Y30p9). Doesn't have any effects on other OSs.
+      enable_battor_trace: a boolean that specifies whether to enable BattOr
+          tracing.
 
       The following ones are specific to chrome tracing. See
       base/trace_event/trace_config.h for more information.
           record_mode: can be any mode in RECORD_MODE_MAP. This corresponds to
                        record modes in chrome.
           enable_systrace: a boolean that specifies whether to enable systrace.
