RVM

RVM can handle both multiple interpreters and multiple sets of gems.

RVM makes installing multiple Ruby interpreters and runtimes easy and consistent.

It provides features such as gemsets that aren't typically supported out of the box on most Ruby installs.

RVM also lets developers use different Rubies in a manner that wont mess with any existing Ruby installation as well as letting them run multiple different Rubies in separate terminals concurrently.

What is new in this release:

• Support for :rubygem_version option to #rvm helper.
