package log // import "log"
 
Package log implements a simple logging package. It defines a type, Logger,
with methods for formatting output. It also has a predefined 'standard'
Logger accessible through helper functions Print[f|ln], Fatal[f|ln], and
Panic[f|ln], which are easier to use than creating a Logger manually. That
logger writes to standard error and prints the date and time of each logged
message. Every log message is output on a separate line: if the message
being printed does not end in a newline, the logger will add one. The Fatal
functions call os.Exit(1) after writing the log message. The Panic functions
call panic after writing the log message.

func Fatal(v ...interface{})
 Fatal is equivalent to Print() followed by a call to os.Exit(1).

type Logger struct {
  // Has unexported fields.
}
 A Logger represents an active logging object that generates lines of output
 to an io.Writer. Each logging operation makes a single call to the Writer's
 Write method. A Logger can be used simultaneously from multiple goroutines;
 it guarantees to serialize access to the Writer.
