# The gems eclass is designed to allow easier installation of
# gems-based ruby packagess and their incorporation into
# the Gentoo Linux system.
#
# - Features:
# gems_location() - Set ${GEMSDIR} with gem install dir and ${GEM_SRC} with path to gem to install
# gems_src_install() - installs a gem into ${D}
# gems_src_unpack() - Does nothing.
# gems_src_compile() - Does nothing.
#
# NOTE:
# See http://dev.gentoo.org/~pythonhead/ruby/gems.html for notes on using gems with portage
