#
# [variables that each port can define]
#
# RUBY			- Set to full path of ruby.  If you set this, the values of the following variables are automatically obtained from the ruby executable: RUBY_VER, RUBY_VERSION, RUBY_NAME, RUBY_ARCH, RUBY_LIBDIR, RUBY_ARCHLIBDIR, RUBY_SITELIBDIR, and RUBY_SITEARCHLIBDIR.
# RUBY_VER		- Set to the alternative short version of ruby in the form of `x.y' (see below for current value).
# USE_RUBY		- Says that the port uses ruby for building and running.
# RUBY_NO_BUILD_DEPENDS	- Says that the port should not build-depend on ruby.
# RUBY_NO_RUN_DEPENDS	- Says that the port should not run-depend on ruby.
# USE_LIBRUBY		- Says that the port uses libruby.
# USE_RUBY_EXTCONF	- Says that the port uses extconf.rb to configure.  Implies USE_RUBY.
# RUBY_EXTCONF		- Set to the alternative name of extconf.rb (default: extconf.rb).
# RUBY_EXTCONF_SUBDIRS	- Set to list of subdirectories, if multiple modules are included.
# USE_RUBY_SETUP	- Says that the port uses setup.rb to configure and build.  Implies USE_RUBY_AMSTD.
# RUBY_SETUP		- Set to the alternative name of setup.rb (default: setup.rb).
# USE_RUBY_AMSTD	- Says that the port uses amstd for building and running.
# USE_RUBY_RD		- Says that the port uses rd to generate documents.
# RUBY_REQUIRE		- Set to a Ruby expression to evaluate before building the port.  The constant "Ruby" is set to the integer version number of ruby, and the result of the expression will be set to RUBY_PROVIDED, which is left undefined if the result is nil, false or a zero-length string.  Implies USE_RUBY.
# RUBY_SHEBANG_FILES	- Specify the files which shebang lines you want to fix.
#
# [variables that each port should not define]
#
# RUBY_PKGNAMEPREFIX	- Common PKGNAMEPREFIX for ruby ports (default: ruby${RUBY_SUFFIX}-)
# RUBY_VERSION		- Full version of ruby without preview/beta suffix in the form of `x.y.z' (see below for current value).
# RUBY_VERSION_CODE	- Full integer version of ruby without preview/beta suffix in the form of `xyz'.
# RUBY_PORTVERSION	- PORTVERSION for the standard ruby ports (ruby, ruby-gdbm, etc.).
# RUBY_DISTNAME		- DISTNAME for the standard ruby ports, i.e. the basename of the ruby distribution tarball.
# RUBY_WRKSRC		- WRKSRC for the ruby port.
#
# RUBY_SHLIBVER		- Major version of libruby (see below for current value).
# RUBY_ARCH		- Directory name of architecture dependent libraries.
# RUBY_SUFFIX		- Suffix for ruby binaries and directories.
# _RUBY_SUFFIX		- String to be used as RUBY_SUFFIX.  Always ${RUBY_VER:S/.//}.
# RUBY_NAME		- Ruby's name with trailing suffix.
#
# RUBY_RD		- Set to full path of rd.
#
# RUBY_PORT		- Set to port path of ruby without PORTSDIR.
# RUBY_AMSTD_PORT	- Set to port path of ruby-amstd without PORTSDIR.
# RUBY_RD_PORT		- Set to port path of rd without PORTSDIR.
#
# DEPEND_LIBRUBY	- Set to LIB_DEPENDS entry for libruby.
# DEPEND_RUBY		- Set to BUILD_DEPENDS/RUN_DEPENDS entry for ruby.
# DEPEND_RUBY_AMSTD	- Set to BUILD_DEPENDS/RUN_DEPENDS entry for ruby-amstd.
# DEPEND_RUBY_RD2	- Set to BUILD_DEPENDS entry for rd.
#
# RUBY_LIBDIR		- Installation path for architecture independent libraries.
# RUBY_ARCHLIBDIR	- Installation path for architecture dependent libraries.
# RUBY_SITELIBDIR	- Installation path for site architecture independent libraries.
# RUBY_SITEARCHLIBDIR	- Installation path for site architecture dependent libraries.
# RUBY_DOCDIR		- Installation path for documents.
# RUBY_EXAMPLESDIR	- Installation path for examples.
