This script also runs continuously on our bots. If somebody breaks presubmit
e.g. by submitting a CL with PRESUBMIT=false or manual commit or a bad revert,
we want the bot to go red:
https://build.chromium.org/p/client.v8/builders/V8%20Linux%20-%20presubmit

Maybe add your check here too?

SGTM.
I'll add it later after testing of PRESUBMIT.py on try bots for some time.

   if success:
     return 0
   else:
     return 1
 
 
 if __name__ == '__main__':
   sys.exit(Main())
