 Package ethlog implements a multi-output leveled logger.

+Logging is asynchrounous and does not block the caller. Message
 formatting is performed by the caller goroutine to avoid incorrect
 logging of mutable state.

-Usage
-
-The Logger type provides named Printf and Println style methods for
-all loglevels. Each ethereum component should have its own logger with
-a unique prefix.
-
-    logger.Infoln("this is info") # > [TAG] This is info
-    logger.Infof("this %v is info", object) # > [TAG] This object is info
-
-ethlog also provides constructors for that wrap io.Writers into a
-standard logger with a settable level:
-
-    filename := "test.log"
-    file, _ := os.OpenFile(filename, os.O_RDWR|os.O_CREATE, os.ModePerm)
-    fileLogSystem := NewStdLogSystem(file, 0, WarnLevel)
-    AddLogSystem(fileLogSystem)
-    stdOutLogSystem := NewStdLogSystem(os.Stdout, 0, WarnLevel)
-    AddLogSystem(stdOutLogSystem)
