DESCRIPTION
ruby-build provides a simple way to compile and install different versions of Ruby on UNIX-like systems.
ruby-build downloads, builds and installs the Ruby version specified in a definition into a prefix directory. Definitions can be chosen
from the list of installed definitions or by specifying a file path for a definition.
rbenv(1) users can also use the provided rbenv install command, which installs Rubies into the rbenv directory.

-k, --keep
Don't delete source code after installation.
-v, --verbose

Install Ruby 1.9.3 (MRI, patch level 0) to ~/rubies/mri-1.9.3
$ ruby-build 1.9.3-p0 ~/rubies/mri-1.9.3
Install Ruby Enterprise Edition 1.8.7 (patch level 2011.03) for rbenv(1):
$ rbenv install ree-1.8.7-2011.03
