log is a Go package implementing a simple logger.

It implements an API somewhat similar to glog, with a focus towards simplicity and integration with standard tools such as systemd.

log.Init()  // only needed once.

log.Debugf("debugging information: %v", x)
log.Infof("something normal happened")
log.Errorf("something bad happened")
log.Fatalf("tragic")

if log.V(3) {  // only entered if -v was >= 3.
	expensiveDebugging()
}

The API should be considered generally stable, and no backwards-incompatible changes are expected.

Some specific symbols are experimental, and are marked as such in their documentation. Those might see backwards-incompatible changes, including removing them entirely.
