+# SYNOPSIS
+#
+#   AX_RUBY_DEVEL([version])
+#
+# DESCRIPTION
+#
+#   This macro checks for Ruby and tries to get the include path to
+#   'ruby.h'. It provides the $(RUBY_CFLAGS) and $(RUBY_LDFLAGS) output
+#   variables. It also exports $(RUBY_EXTRA_LIBS) for embedding Ruby in your
+#   code.
+#
+#   You can search for some particular version of Ruby by passing a
+#   parameter to this macro, for example "1.8.6".
