title: How to set Golang's log output back to console?
body: <p>Google Go's <code>log</code> package has <a href="https://golang.org/pkg/log/#SetOutput">SetOutput</a> - a function for setting the log output to any io.Writer. After I set it for testing, I would like to revert the output back to the standard console output - how do I do that? I don't see any obvious way of resetting it in the <code>log</code> or <code>io</code> packages.</p>
