13.6.4 Logging errors

A new API allows your programs to generate a bug form and write it to a log file, optionally printing a message saying that this has been done. See dbg:log-bug-form for the details.

Also, dbg:output-backtrace is now documented, for use when you want to include Lisp backtraces in log files which you control directly.

Note: Adequate logging of errors is frequently omitted from customer applications, but it is important for the maintenance of any complex application. If your LispWorks application does not log errors via its error handlers, use one of the above APIs to add error logging now!
