Subject: emacs .el files

the following two lines should get you going, the first line is only
necessary if you have not already placed the files in your site-lisp
directory

 (add-to-list 'load-path "~/path/to/directory/containing/ruby-mode.el")
 (autoload 'ruby-mode "ruby-mode" "Mode for editing ruby source files" t)

if you're feeling ambitious about adding more functionality here is an
excerpt from my own site-start.el
