Just a quick question.  As I understand it, the way you "put a
breakpoint" in your code to debug with Slime is, as the manual says:
----
SLIME has a custom Emacs-based debugger called SLDB. Conditions
signalled in the Lisp
system invoke SLDB in Emacs by way of the Lisp *DEBUGGER-HOOK*.

SLDB pops up a buffer when a condition is signalled. The buffer displays
a description
of the condition, a list of restarts, and a backtrace. Commands are
offered for invoking
restarts, examining the backtrace, and poking around in stack frames.
----
I'm new to lisp and haven't done any serious signaling yet.
Presumably this means that I need to do something like...
---
(signal *debugger-hook*)
---
But then I need a restart to be able to continue after I've examined
the stack frame, right?  Can someone tell me how to do that?  I can't
find any examples anywhere in the Slime docs.

No doubt you serious lispers do this several times a day, so it should
be an easy question.

Thanks,
Erik

Put (break) forms where you want to stop and examine program
state. You can resume from a break by picking the right restart in
sldb.

Bingo!  I KNEW it was a simple question.  Thanks, Zach.
