This example shows how to setup an environment running Rails 3 beta under 1.9.1 with a 'rails3' gem set.
∴ rvm update --head
# ((Open a new shell)) or do 'rvm reload'
# If you do not already have the ruby interpreter installed, install it:
∴ rvm install 1.9.1
# Switch to 1.9.1 and gemset rails3, create if it doesn't exist.
∴ rvm --create use 1.9.1@rails3
# Download the gems(et) file for rails3 beta 2:
∴ curl -L http://rvm.beginrescueend.com/gemsets/rails3b2.gems -o rails3.gems
# Load the gems(et) file into the current gem environment.
∴ rvm gemset import rails3.gems
# Check to see we now have Rails 3.0.0 beta
∴ rails --version
Rails 3.0.0.beta
