spellin & spellout

[USAFAS]

Hi,

	I feel kind of dumb, but I can't make any sense of the
man regarding spellin & spellout.  Can you help me?

	1.  Do they have any benefit for a non-superuser?
	2.  Can they be used to maintain a private dictionary?
	3.  Can I use spell with a private dictionary?

	I have written my own private spelling checker and corrector
but it seems to me that spellin and spellout should help in this.
Right now, I'm relying on "comm" and "grep."

		Thanks,
