title: RVM- Multiple ruby versions for different projects on same server
body: <p>I am configuring a new server for multiple rails 2.x/3.x projects, with multiple ruby versions 1.8.7/1.9.2 using RVM.<br>
  I want to know how to set a project to use particular version of ruby and another project to use another version of ruby?  </p>
