# The ruby eclass is designed to allow easier installation of ruby
# softwares, and their incorporation into the Gentoo Linux system.

# src_unpack, src_compile and src_install call a set of functions to emerge
# ruby with SLOT support; econf, emake and einstall is a wrapper for ruby
# to automate configuration, make and install process (they override default
# econf, emake and einstall defined by ebuild.sh respectively).

# Variables:
# USE_RUBY	Space delimited list of supported ruby.
#		Set it to "any" if it installs only version independent files.
#		If your ebuild supports both ruby 1.6 and 1.8 but has version
#		depenedent files such as libraries, set it to something like
#		"ruby16 ruby18". Possible values are "any ruby16 shim18 ruby18"
#		Note: USE_RUBY="shim18" doesn't take any effect at the moment.
# WITH_RUBY	Contains space delimited list of installed ruby which is
#		supported (supported ruby should be specified in USE_RUBY).
#		It is automatically defined if your ebuild set DEPEND list
#		correctly, so usually you shouldn't set this variable by hand.
# EXTRA_ECONF	You can pass extra arguments to econf by defining this
#		variable. Note that you cannot specify them by command line
#		if you are using <sys-apps/portage-2.0.49-r17.
