var IsDebugging = false

IsDebugging controls debugging output.

If this is true, debugging messages will be printed. Expensive debugging operations can be wrapped in `if log.IsDebugging {}`.

func Debug(msg string, v ...interface{})

Debug prints an error severity DEBUG to the log.

Debug will only print if IsDebugging is true.

func Err(msg string, v ...interface{})

Err prints an error of severity ERROR to the log.

func Info(msg string, v ...interface{})

Info prints an error of severity INFO to the log.

func Warn(msg string, v ...interface{})

Warn prints an error severity WARN to the log.

	Printf(format string, v ...interface{})
}

The logger that this prints to.
