The Emacs-21 version of the docstring says (among other things):

    The above three arguments can be skipped if keyword arguments are
    used (see below).
    
    BODY contains code that will be executed each time the mode is 
(dis)activated.
      It will be executed after any toggling but before running the hooks.
      BODY can start with a list of CL-style keys specifying additional 
arguments.
      The following keyword arguments are supported:
    :group   Followed by the group name to use for any generated `defcustom'.
    :global  If non-nil specifies that the minor mode is not meant to be
             buffer-local.  By default, the variable is made buffer-local.
    :init-value  Same as the INIT-VALUE argument.
    :lighter  Same as the LIGHTER argument.

The end of the docstring on Emacs-24 additionally says:

    For example, you could write
      (define-minor-mode foo-mode "If enabled, foo on you!"
        :lighter " Foo" :require 'foo :global t :group 'hassle :version "27.5"
        ...BODY CODE...)

Do you believe me now?  ;-)
