-The default language mode is 1.8, so if you invoke rbx with no other options,
-you’ll be running in 1.8 mode. You can change the default mode with a configure

-
-./configure --default-version=1.9 If you configure Rubinius to have a default
-language mode of 1.9, you can access 1.8 mode with the -X18 runtime option as
-discussed above.

+6. Language Modes
+
+Rubinius implements multiple Ruby language features in one executable. You can
+select the language mode at runtime by passing the -X18, -X19, or -X20 command
+line option or by setting the RBXOPT environment variable. The following two
+commands are equivalent:
+
+ RBXOPT=-X19 bin/rbx -v
+ bin/rbx -X19 -v
+
+The default language mode is 1.8. You can change which language modes are
+enabled and which one is the default mode with configure options.
+
+For example, to enable both 1.9 and 2.0 modes, with 1.9 the default, use the
+follwing configure options:
+
+./configure --enable-version=1.9,2.0 --default-version=1.9
+
+The --enable-version option takes a comma-separated list of versions. The
+--default-version option takes a single version. If only a single version is
+enabled, setting the default version is redundant.
