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

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