-;;  This file adds support for ruby-debug (rdebug) in Emacs.
-;;  Copyright (C) 2007 Martin Nordholts <enselic@gmail.com>
-;;
-;;  This file is based on 'rubydb3x.el' that comes with Ruby which is
-;;  Copyright (C) Yukihiro Matsumoto aka Matz
-;;
-;;  Installation:
-;;  -------------
-;;
-;;    1.  Make sure you have ruby-debug on your system (test by running
-;;        the commmand 'rdebug -v' in a shell).
-;;
-;;    2.  Copy this file into e.g. ~/.elisp and make sure this is in
-;;        your ~/.emacs:
-;;
-;;          (add-to-list 'load-path "~/.elisp")
-;;          (load-library "rdebug")
-;;
-;;        you can then start the debugger with M-x rdebug
-;;
-;;    3.  Setup convenient keybindings etc. This is what I have:
-;;
-;;          (global-set-key [f9] 'gud-step)
-;;          (global-set-key [f10] 'gud-next)
-;;          (global-set-key [f11] 'gud-cont)
-;;
-;;          (global-set-key "\C-c\C-d" 'rdebug)
-;;
-;;    4. Debug like crazy!
-;;
-;;  Bugs:
-;;  -----
-;;
-;;    Basic functionality works fine, though there might be a bug hiding somewhere.
