    Add the following to the ~/.bashrc or ~/.zshrc file:

      source #{opt_share}/chruby/chruby.sh

    By default chruby will search for Rubies installed into /opt/rubies/ or
    ~/.rubies/. For non-standard installation locations, simply set the RUBIES
    variable after loading chruby.sh:

      RUBIES=(
        /opt/jruby-1.7.0
        $HOME/src/rubinius
      )

    If you are migrating from another Ruby manager, set `RUBIES` accordingly:

      RVM:   RUBIES=(~/.rvm/rubies/*)
      rbenv: RUBIES=(~/.rbenv/versions/*)
      rbfu:  RUBIES=(~/.rbfu/rubies/*)

    To enable auto-switching of Rubies specified by .ruby-version files,
    add the following to ~/.bashrc or ~/.zshrc:

      source #{opt_share}/chruby/auto.sh
    EOS
  end
