Mr. Guid 0.1.4 has been released! Vast improvements have been
made to make Mr. Guid more keyboard friendly. A list of these
shortcuts can be found at http://mr-guid.rubyforge.org

Also, standard output is now displayed properly in the output
window, a nasty bug involving tracing has been fixed, and an
option to hide the toolbar was added.

Mitchell's Ruby GUI Debugger (Mr. Guid) is a simple Ruby GUI
debugger written in Ruby using the Ruby/Gtk2 bindings for
GTK+. It is only meant to be a debugger, not an editor or IDE.
