## Description

This codec handles fluentd’s msgpack schema.
For example, you can receive logs from `fluent-logger-ruby` with:
```
    input {
      tcp {
        codec => fluent
        port => 4000
      }
    }
```

And from your ruby code in your own application:
```
    logger = Fluent::Logger::FluentLogger.new(nil, :host => "example.log", :port => 4000)
    logger.post("some_tag", { "your" => "data", "here" => "yay!" })
```

Notes:
- the fluent uses a second-precision time for events, so you will never see subsecond precision on events processed by this codec.
