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.

OPTIONS

       --definitions
              List available definitions.

       -k, --keep

              Show ruby-build version and exit.

              Show usage information and exit.
