If you wouldn't mind, and with the goal of evangelization, could you briefly explain what the advantages of asl over syslog are? "Briefly" speaking, it allows for an open-ended set of log message attributes (unlike the fixed set of facilities in syslog(3)), it unifies the character encoding of all log messages (so messages aren't in an arbitrarily mixed set of encodings), it eliminates the profusion of individual log files in favor of a single log database, it provides an advanced search and filter API, it allows application logging behavior to be controlled remotely, and it's got a much more flexible plug-in model for handling messages in a variety of ways. It's hard to encapsulate everything that took about half an hour (and with the benefit of slides) to describe at the last WWDC, however, so those with ADC memberships are encouraged to view the on-line presentation video (session #510, "Core OS Enhancements for BSD Developers") and/or download the session slides. I'm not trying to cop out on evangelizing ASL here, it's simply far more efficient for me to leverage resources that already exist for this (see also http:// developer.apple.com/samplecode/SampleD/SampleD.html). Those without ADC memberships can also download the sources from places like http://darwinsource.opendarwin.org/10.4.4.ppc/ syslog-13.1/ and check it out.
