Subject: Specifying Ruby Version from Command Line

I have two versions of Ruby installed (1.8 and 1.9).  When starting a
Ruby script from the command window, how do I specify which version of
Ruby I want to use?   I'm assuming there is some option for this that I
can set, but I don't know what it is.
