-;;; Inferior Ruby Mode - ruby process in a buffer.
-;;;                      adapted from cmuscheme.el
-;;;
-;;; Usage:
-;;;
-;;; (0) check ruby-program-name variable that can run your environment.
-;;;
-;;; (1) modify .emacs to use ruby-mode 
-;;;     for example :
-;;;
-;;;    (autoload 'ruby-mode "ruby-mode"
-;;;      "Mode for editing ruby source files")
-;;;    (setq auto-mode-alist
-;;;          (append '(("\\.rb$" . ruby-mode)) auto-mode-alist))
-;;;    (setq interpreter-mode-alist (append '(("^#!.*ruby" . ruby-mode))
-;;;    				     interpreter-mode-alist))
-;;;    
-;;; (2) set to road inf-ruby and set inf-ruby key definition in ruby-mode.
-;;;
-;;;    (autoload 'run-ruby "inf-ruby"
-;;;      "Run an inferior Ruby process")
-;;;    (autoload 'inf-ruby-keys "inf-ruby"
-;;;      "Set local key defs for inf-ruby in ruby-mode")
-;;;    (add-hook 'ruby-mode-hook
-;;;          '(lambda ()
-;;;             (inf-ruby-keys)
-;;;    ))

-
-The following commands are available:
-\\{inferior-ruby-mode-map}
-
-A ruby process can be fired up with M-x run-ruby.
-
-Customisation: Entry to this mode runs the hooks on comint-mode-hook and
-inferior-ruby-mode-hook (in that order).
-
-You can send text to the inferior ruby process from other buffers containing
-Ruby source.
-    switch-to-ruby switches the current buffer to the ruby process buffer.
-    ruby-send-definition sends the current definition to the ruby process.
-    ruby-send-region sends the current region to the ruby process.
-
-    ruby-send-definition-and-go, ruby-send-region-and-go,
-        switch to the ruby process buffer after sending their text.
-For information on running multiple processes in multiple buffers, see
-documentation for variable ruby-buffer.
-
-Commands:
-Return after the end of the process' output sends the text from the 
-    end of process to point.
-Return before the end of the process' output copies the sexp ending at point
-    to the end of the process' output, and sends it.
-Delete converts tabs to spaces as it moves back.
-Tab indents for ruby; with argument, shifts rest
-    of expression rigidly with the current line.
-C-M-q does Tab on each line starting within following expression.
-Paragraphs are separated only by blank lines.  # start comments.
-If you accidentally suspend your process, use \\[comint-continue-subjob]
-to continue it."
