+// Package zap provides fast, structured, leveled logging.
+//
+// For applications that log in the hot path, reflection-based serialization
+// and string formatting are prohibitively expensive - they're CPU-intensive
+// and make many small allocations. Put differently, using json.Marshal and
+// fmt.Fprintf to log tons of interface{} makes your application slow.
+//
+// Zap takes a different approach. It includes a reflection-free,
+// zero-allocation JSON encoder, and the base Logger strives to avoid
+// serialization overhead and allocations wherever possible. By building the
+// high-level SugaredLogger on that foundation, zap lets users choose when
+// they need to count every allocation and when they'd prefer a more familiar,
+// loosely typed API.
+//
+// # Choosing a Logger
+//
+// In contexts where performance is nice, but not critical, use the
+// SugaredLogger. It's 4-10x faster than other structured logging packages and
+// supports both structured and printf-style logging. Like log15 and go-kit,
+// the SugaredLogger's structured logging APIs are loosely typed and accept a
+// variadic number of key-value pairs. (For more advanced use cases, they also
+// accept strongly typed fields - see the SugaredLogger.With documentation for
+// details.)
+//
+//	sugar := zap.NewExample().Sugar()
+//	defer sugar.Sync()
+//	sugar.Infow("failed to fetch URL",
+//	  "url", "http://example.com",
+//	  "attempt", 3,
+//	  "backoff", time.Second,
+//	)
+//	sugar.Infof("failed to fetch URL: %s", "http://example.com")
+//
+// By default, loggers are unbuffered. However, since zap's low-level APIs
+// allow buffering, calling Sync before letting your process exit is a good
+// habit.
+//
+// In the rare contexts where every microsecond and every allocation matter,
+// use the Logger. It's even faster than the SugaredLogger and allocates far
+// less, but it only supports strongly-typed, structured logging.

+//	  zap.String("url", "http://example.com"),
+//	  zap.Int("attempt", 3),
+//	  zap.Duration("backoff", time.Second),
+//	)
+//
+// Choosing between the Logger and SugaredLogger doesn't need to be an
+// application-wide decision: converting between the two is simple and
+// inexpensive.
+//
+//	logger := zap.NewExample()
+//	defer logger.Sync()
+//	sugar := logger.Sugar()

+//
+// # Configuring Zap
+//
+// The simplest way to build a Logger is to use zap's opinionated presets:
+// NewExample, NewProduction, and NewDevelopment. These presets build a logger
+// with a single function call:
+//
+//	logger, err := zap.NewProduction()
+//	if err != nil {
+//	  log.Fatalf("can't initialize zap logger: %v", err)
+//	}
+//	defer logger.Sync()
+//
+// Presets are fine for small projects, but larger projects and organizations
+// naturally require a bit more customization. For most users, zap's Config
+// struct strikes the right balance between flexibility and convenience. See
+// the package-level BasicConfiguration example for sample code.
+//
+// More unusual configurations (splitting output between files, sending logs
+// to a message queue, etc.) are possible, but require direct use of
+// go.uber.org/zap/zapcore. See the package-level AdvancedConfiguration
+// example for sample code.
+//
+// # Extending Zap
+//
+// The zap package itself is a relatively thin wrapper around the interfaces
+// in go.uber.org/zap/zapcore. Extending zap to support a new encoding (e.g.,
+// BSON), a new log sink (e.g., Kafka), or something more exotic (perhaps an
+// exception aggregation service, like Sentry or Rollbar) typically requires
+// implementing the zapcore.Encoder, zapcore.WriteSyncer, or zapcore.Core
+// interfaces. See the zapcore documentation for details.
+//
+// Similarly, package authors can use the high-performance Encoder and Core
+// implementations in the zapcore package to build their own loggers.
+//
+// # Frequently Asked Questions
+//
+// An FAQ covering everything from installation errors to design decisions is
+// available at https://github.com/uber-go/zap/blob/master/FAQ.md.

+//
+// # GET
+//
+// The GET request returns a JSON description of the current logging level like:
+//
+//	{"level":"info"}
+//
+// # PUT
+//
+// The PUT request changes the logging level. It is perfectly safe to change the
+// logging level while a program is running. Two content types are supported:
+//
+//	Content-Type: application/x-www-form-urlencoded
+//
+// With this content type, the level can be provided through the request body or
+// a query parameter. The log level is URL encoded like:
+//
+//	level=debug
+//
+// The request body takes precedence over the query parameter, if both are
+// specified.
+//
+// This content type is the default for a curl PUT request. Following are two
+// example curl requests that both set the logging level to debug.
+//
+//	curl -X PUT localhost:8080/log/level?level=debug
+//	curl -X PUT localhost:8080/log/level -d level=debug
+//
+// For any other content type, the payload is expected to be JSON encoded and
+// look like:
+//
+//	{"level":"info"}
