Package vlog add leveled log on std log(golang.org/pkg/log/)

It implements most std log functions(except logger), variables and add provides V-style logging controlled by the -v flag or SetLogLevel()
If flag.Parse be called before any logging, -v flag(default 0) use automaticlly.

if !vlog.IsLevelParsed() { vlog.SetLogLevel(3) } vlog.GetLogLevel() vlog.Println("Prepare to repel boarders") vlog.Fatalf("Initialization failed: %s", err)

See the documentation for the V function for an explanation of these examples:

if vlog.V(2) { vlog.Print("Starting transaction...") } vlog.V(2).Println("Processed", nItems, "elements")
