Hi Midhun,

That command line looks reasonable to me. I'm not sure what is causing your
unexpected behavior. Again, I encourage you to read through *all* of the
scripts in configs/ that fs.py touches to understand what the command line
options mean. Maybe some option you're setting is overriding the --ruby
option (very likely).
