Thu Nov 4 11:41:31 PST 2004 olaf * Numerous small changes and bugfixes. Now all tools (execpt hat-anim) can call hat-explore and vice versa. Hat-explore always shows the full stack, even if started with specific redex. (So it nearly includes hat-trail.) Stack elements are numbered for better orientation in deep stack.
