// Package log provides logging functionality to notation.
// Users who want to enable logging option in notation should implement the
// log.Logger interface and include it in context by calling log.WithLogger.
// 3rd party loggers that implement log.Logger: github.com/uber-go/zap.SugaredLogger
// and github.com/sirupsen/logrus.Logger.
