All ISC code now removed or merged.  Just need to remove the

“This parrot is no more. It has ceased to be. It's expired and gone
to meet its maker. This is a late parrot. It's a stiff. Bereft of life,
it rests in peace. If you hadn't nailed it to the perch, it would be
pushing up the daisies. It's rung down the curtain and joined the choir
invisible. This is an ex-parrot.” -- John Cleese
