rspec users - Mar 2008 - Command line option to run a story scenario?

Hi Folks,

Quick question.

Anybody know if there is a command line option to run an individual  
scenario for the given story

e.g.  something like:
ruby stories/my_story.rb  -s "the name of the scenario"

Thanks in advance,
Martin.
PS: Really loving story runner at the moment. Got it hooked up with  
Selenium and the results are
really nice.
