If you're using OS X 10.4 or later, you may want to check out the
Apple System Logger facility (a great series of posts on ASL start at
http://boredzo.org/blog/archives/2008-01-19/next-week-apple-system-logger).
It's not too hard to write your own Objective-C/#define wrapper around
ASL to get much more functionality than you can via NSLog (including
choosing where to direct logs, log message format, etc.)
