// These flags define which text to prefix to each log entry generated
// by the Logger. Bits are or'ed together to control what's printed.
// There is no control over the order they appear (the order listed
// here) or the format they present (as described in the comments).
// The prefix is followed by a colon only if more than time is stated
// is specified. For example, flags Ldate | Ltime
// produce, 2009/01/23 01:23:23 message.
// The standard is:
// 2009/01/23 01:23:23 ...a/logger/c/d.go:23:runtime.Caller() [I]: message

Llongfile // full file name and line number: /a/logger/c/d.go:23
Lshortfile // final file name element and line number: d.go:23. overrides Llongfile
Lfuncname // function name of the caller: runtime.Caller()
Lshortfuncname // last part of the function name

// Last 20 characters of the filename
