It isn't a brief mention, it's a whole section dedicated to
spell-checking commands.

If you read that section, you will realize that "ispell" is the name
of the Lisp package, and does not mean we only use "ispell" the
program.  That section says so at its very beginning.

We already have such a generic framework.

The default is already aspell:

  (defcustom ispell-program-name
    (or (executable-find "aspell")
	(executable-find "ispell")
	(executable-find "hunspell")
	"ispell")

As you see, Emacs looks for a program in the order shown above, with
aspell being the first one.

> Does one use the command this way
> 
> (setq ispell-program-name "aspell)
> 
> or this way
>

If aspell is on PATH, it doesn't matter which form you use.  If it is
not on PATH, then you should use the absolute file name.
