How do I see the statistics for rcov from the command line?

I'm running the built-in rake task to generate rcov reports:

rake spec:rcov

This generate files in my coverage directory, but I would like to see some aggregate stats output to the command console.

Something like the total coverage and number of lines being tested in a format similar to what you get 开发者_Python百科when you run "rake stats"

Anyone know of a way to do this?

I added the --text-summary option to my rcov.opts and it outputs the data I need.
