The current version I have does not try to enforce a particular speller
- both ispell and aspell are supported.  The choice is determined by the
setting of the customized variable `ispell-prefer-aspell' when both ispell
and aspell exist on the system.

I had used the function `exec-installed-p' which had it's roots in APEL
(A Portable Emacs Library).  In digging deeper, it appears that this is
not necessary as the standard emacs function `executable-find' appears
to have the same desired functionality.

Here are the variables:


(defcustom ispell-prefer-aspell nil
  "*Select preference between using the `ispell' or `aspell' program.
`ispell' is used by default.
When this variable is set, `aspell' is used if it is installed on the system."
  :type 'boolean
  :group 'ispell)


(defcustom ispell-program-name
  (or (and (executable-find "aspell")
           (or ispell-prefer-aspell
               (not (executable-find "ispell")))
           "aspell")
      "ispell")
  "Program invoked by \\[ispell-word] and \\[ispell-region] commands."
  :type 'string
  :group 'ispell)


I'm sure you'll argue to make `ispell-prefer-aspell' set by default ;-)
It is only used in the above location in the code.


I have several other patches, improvements to integrate into the current
version of ispell as well.
