ruby-single.eclass - An eclass for Ruby packages not installed for multiple implementations.
An eclass for packages which don't support being installed for
multiple Ruby implementations. This mostly includes ruby-based
scripts. Set USE_RUBY to include all the ruby targets that have been
verified to work and include the eclass. RUBY_DEPS is now available to
pull in the dependency on the requested ruby targets.
This variable contains a space separated list of targets (see above) a package
is compatible to. It must be set before the `inherit' call. There is no
default. All ebuilds are expected to set this variable.
This is an eclass-generated Ruby dependency string for all
implementations listed in USE_RUBY. Any one of the supported ruby
targets will satisfy this dependency. A dependency on
virtual/rubygems is also added to ensure that this is installed
in time for the package to use it.
