-/* All messages are initially emitted by one of the four functions below.
- * debug() is generally invoked via D() so that mostly you just do a test
- * rather than a complete subroutine call.
- *
- * Messages are dispatched via log_default. This defaults to log_stderr.
- * daemonize() will turn off log_stderr and use log_syslog instead.
- *
- * fatal() will call exitfn() with a nonzero status. The default value is
- * exit(), but it should be set to _exit() anywhere but the 'main line' of the
- * program, to guarantee that exit() gets called at most once.
