  10 # @DESCRIPTION:
  11 # The ruby-utils eclass is designed to allow an easier installation of
  12 # Ruby scripts and bindings for non-ruby packages.
  13 #
  14 # This eclass does not set any metadata variables nor export any phase
  15 # functions. It can be inherited safely.

  22 # @DESCRIPTION:
  23 # This variable lists all the known ruby targets in preference of use as
  24 # determined by the ruby team. By using this ordering rather than the
  25 # USE_RUBY mandated ordering we have more control over which ruby
  26 # implementation will be installed first (and thus eselected). This will
  27 # provide for a better first installation experience.
