You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: listing03.go
    path of file: ./repos/learning/golang/source_code/go-in-action-code/chapter8/listing03
    
    the code of the file until where you have to start completion: // This sample program demonstrates how to use the base log package.
package main

import (
	"log"
)

func init() {
	log.SetPrefix("TRACE: ")
	log.SetFlags(log.Ldate | log
    
func main() {
	// Println writes to the standard logger.
	log.Println("message")

	// Fatalln is Println() followed by a call to os.Exit(1).
	log.Fatalln("fatal message")

	// Panicln is Println() followed by a call to panic().
	log.Panicln("panic message")
}
