+6. Dynamic loading					*ruby-dynamic*
+
+On MS-Windows the Ruby library can be loaded dynamically.  The |:version|
+output then includes |+ruby/dyn|.
+
+This means that Vim will search for the Ruby DLL file only when needed.  When
+you don't use the Ruby interface you don't need it, thus you can use Vim
+without this DLL file.
+
+To use the Ruby interface the Ruby DLL must be in your search path.  In a
+console window type "path" to see what directories are used.
+
+The name of the DLL must match the Ruby version Vim was compiled with.
+Currently the name is "ruby18.dll".  That is for Ruby 1.8.  To know for sure
+edit "gvim.exe" and search for "ruby\d*.dll\c".
