Logging is useful to detect errors in the first place (see the other
thread where the bug wasn't noticed until the logfiles were read).
tracing is useful if it's known that there's an error, but it's not
clear that where that error actually is.

"Beware of bugs in the above code; I have only proved it correct, not
  tried it."
