ruby-build provides a simple way to compile and install different
versions of Ruby.
.
ruby-build is great when you want to build Ruby versions that are not
available via APT, for example if you need legacy or bleeding edge
versions of Ruby.
.
Combined with rbenv, ruby-build lets you easily install and switch
between different implementations of Ruby, such as MRI, JRuby, REE
and others.
