Yes, indeed, sorry about that.  The incorrect doc was in 1.8.1 through
1.8.3, but has been removed now from 1.8.x CVS, so will no longer be
misleading people in 1.8.4.

Yes.  guile-debugging is a slight misnomer, because it actually
provides (or tries to) two overlapping things:

- Scheme-accessible breakpoints (and traps, and other bits of Scheme
  infrastructure)

- modes, keystrokes etc. for using Guile conveniently from within
  Emacs.

The two things overlap, because one of the nicest bits (IMHO :-)) is
how Emacs displays the Scheme stack when stopped at a breakpoint, and
allows easy navigation of it.

I'm sorry, I've put something up now at
http://www.ossau.uklinux.net/guile-debugging that hopefully makes
sense, and links to the correct doc.

Thanks for raising your bug.  The others aren't assigned because I'm
(so far) the only developer, so there isn't much point.

It has most of the right memes, but a lot of the details have moved
on.

guile-debugging could be installed anywhere, so long as you add the
install location to your GUILE_LOAD_PATH.  In practice, it's most
convenient to install it somewhere that's already in the standard
GUILE_LOAD_PATH, i.e. /usr/local/share/guile/site or
/usr/share/guile/site (depending on the prefix that Guile was
built).

Thanks for your interest.  Please do let me know how you find it, once
you get past these initial troubles.
