[plt-scheme] Announcing MzTake: a scriptable debugger

Vadim, thanks for your detailed comments.

Guillaume Marceau and Greg Cooper did this too (ie, using JDWP).  They
used some of the code from Ruby to bootstrap their debugger.  We have
a paper about it at ASE 2004 that you can get from my Web page.

But, we love Scheme more.

Interesting -- I hadn't.  Conceptually it doesn't look that much more
clever than Tolmach and Appel's debugger (and fie on the author for
writing a related work section that doesn't actually *relate* *work*
(and the program committee for not insisting on it, either)).  You
could also do something like this using the new path-exploration tools
available, such as Java PathFinder (not PathFindler, which is what I
originally typed).
