8# The gems eclass is designed to allow easier installation of 11# @BLURB: Eclass helping with the installation of RubyGems
9# gems-based ruby packagess and their incorporation into 12# @DESCRIPTION:
10# the Gentoo Linux system.
11#
12# - Features:
13# gems_location() - Set ${GEMSDIR} with gem install dir and ${GEM_SRC} with path to gem to install
14# gems_src_install() - installs a gem into ${D}
15# gems_src_unpack() - Does nothing.
16# gems_src_compile() - Does nothing.

18# NOTE:
19# See http://dev.gentoo.org/~pythonhead/ruby/gems.html for notes on using gems with portage 13# See http://dev.gentoo.org/~pythonhead/ruby/gems.html for notes on using gems with Portage.

15# @ECLASS-VARIABLE: USE_RUBY
16# @DESCRIPTION:
17# Ruby versions the gem is compatible to. The eclass will install the gem for
18# versions that are compatible and installed on the system. Format: rubyDD where
19# DD is the two-digit version suffix (e.g.: USE_RUBY="ruby19" for Ruby 1.9.1)
