in reply to Defensive Programming and Audit Trails

I've recently wrote a program in which I used extensive logging. It was a C program, but the principles remain. I didn't use multiple -v flags to indicate what to log, but instead, I logged everything with syslog (the program is run as a daemon, so syslog is a natural choice). The advantage of logging with syslog is that you can configure outside of the program what you will keep. And very importantly, you can change what you are interested in without restarting the program. Furthermore, you can decide to keep errors in a separate file, which you retain longer than say, notices.
