"the source code to itself"  -- that's what it sez.

Not so big a cheat.  It seems it really would produce it's own source,
rather than just a copy or whatever its buggy little self happens to
contain.  This way, you are _certain_ that the program is what its
source looks like.  Except now you have to keep them together
forever...but it may be the only answer that fits the spec perfectly.
