-# YAML marshaling and unmarshaling support for Go
-
-[![Build Status](https://travis-ci.org/ghodss/yaml.svg)](https://travis-ci.org/ghodss/yaml)
-
-## Introduction
-
-A wrapper around [go-yaml](https://github.com/go-yaml/yaml) designed to enable a better way of handling YAML when marshaling to and from structs.
-
-In short, this library first converts YAML to JSON using go-yaml and then uses `json.Marshal` and `json.Unmarshal` to convert to or from the struct. This means that it effectively reuses the JSON struct tags as well as the custom JSON methods `MarshalJSON` and `UnmarshalJSON` unlike go-yaml. For a detailed overview of the rationale behind this method, [see this blog post](http://ghodss.com/2014/the-right-way-to-handle-yaml-in-golang/).
-
-## Compatibility
-
-This package uses [go-yaml](https://github.com/go-yaml/yaml) and therefore supports [everything go-yaml supports](https://github.com/go-yaml/yaml#compatibility).
-
-## Caveats
-
-**Caveat #1:** When using `yaml.Marshal` and `yaml.Unmarshal`, binary data should NOT be preceded with the `!!binary` YAML tag. If you do, go-yaml will convert the binary data from base64 to native binary data, which is not compatible with JSON. You can still use binary in your YAML files though - just store them without the `!!binary` tag and decode the base64 in your code (e.g. in the custom JSON methods `MarshalJSON` and `UnmarshalJSON`). This also has the benefit that your YAML and your JSON binary data will be decoded exactly the same way. As an example:
-
-```
-BAD:
-	exampleKey: !!binary gIGC
-
-GOOD:
-	exampleKey: gIGC
-... and decode the base64 data in your code.
-```
-
-**Caveat #2:** When using `YAMLToJSON` directly, maps with keys that are maps will result in an error since this is not supported by JSON. This error will occur in `Unmarshal` as well since you can't unmarshal map keys anyways since struct fields can't be keys.
-
-## Installation and usage
-
-To install, run:
-
-```
-$ go get github.com/ghodss/yaml
-```
-
-And import using:
-
-```
-import "github.com/ghodss/yaml"
-```
-
-Usage is very similar to the JSON library:
-
-```go
-package main
-
-import (
-	"fmt"
-
-	"github.com/ghodss/yaml"
-)
-
-type Person struct {
-	Name string `json:"name"` // Affects YAML field names too.
-	Age  int    `json:"age"`
-}
-
-func main() {
-	// Marshal a Person struct to YAML.
-	p := Person{"John", 30}
-	y, err := yaml.Marshal(p)
-	if err != nil {
-		fmt.Printf("err: %v\n", err)
-		return
-	}
-	fmt.Println(string(y))
-	/* Output:
-	age: 30
-	name: John
-	*/
-
-	// Unmarshal the YAML back into a Person struct.
-	var p2 Person
-	err = yaml.Unmarshal(y, &p2)
-	if err != nil {
-		fmt.Printf("err: %v\n", err)
-		return
-	}
-	fmt.Println(p2)
-	/* Output:
-	{John 30}
-	*/
-}
-```
-
-`yaml.YAMLToJSON` and `yaml.JSONToYAML` methods are also available:
-
-```go
-package main
-
-import (
-	"fmt"
-
-	"github.com/ghodss/yaml"
-)
-
-func main() {
-	j := []byte(`{"name": "John", "age": 30}`)
-	y, err := yaml.JSONToYAML(j)
-	if err != nil {
-		fmt.Printf("err: %v\n", err)
-		return
-	}
-	fmt.Println(string(y))
-	/* Output:
-	name: John
-	age: 30
-	*/
-	j2, err := yaml.YAMLToJSON(y)
-	if err != nil {
-		fmt.Printf("err: %v\n", err)
-		return
-	}
-	fmt.Println(string(j2))
-	/* Output:
-	{"age":30,"name":"John"}
-	*/
-}
-```

-Leveled execution logs for Go.
-
-This is an efficient pure Go implementation of leveled logs in the
-manner of the open source C++ package
-	https://github.com/google/glog
-
-By binding methods to booleans it is possible to use the log package
-without paying the expense of evaluating the arguments to the log.
-Through the -vmodule flag, the package also provides fine-grained
-control over logging at the file level.
-
-The comment from glog.go introduces the ideas:
-
-	Package glog implements logging analogous to the Google-internal
-	C++ INFO/ERROR/V setup.  It provides functions Info, Warning,
-	Error, Fatal, plus formatting variants such as Infof. It
-	also provides V-style logging controlled by the -v and
-	-vmodule=file=2 flags.
-	
-	Basic examples:
-	
-		glog.Info("Prepare to repel boarders")
-	
-		glog.Fatalf("Initialization failed: %s", err)
-	
-	See the documentation for the V function for an explanation
-	of these examples:
-	
-		if glog.V(2) {
-			glog.Info("Starting transaction...")
-		}
-	
-		glog.V(2).Infoln("Processed", nItems, "elements")
-
-
-The repository contains an open source version of the log package
-used inside Google. The master copy of the source lives inside
-Google, not here. The code in this repo is for export only and is not itself
-under development. Feature requests will be ignored.
-
-Send bug reports to golang-nuts@googlegroups.com.

-// By default, all log statements write to files in a temporary directory.
-// This package provides several flags that modify this behavior.
-// As a result, flag.Parse must be called before any logging is done.
-//
-//	-logtostderr=false

-//	-alsologtostderr=false
-//		Logs are written to standard error as well as to files.
-//	-stderrthreshold=ERROR
-//		Log events at or above this severity are logged to standard
-//		error as well as to files.
-//	-log_dir=""
-//		Log files will be written to this directory instead of the
-//		default temporary directory.
-//
-//	Other flags provide aids to debugging.
-//
-//	-log_backtrace_at=""
-//		When set to a file and line number holding a logging statement,
-//		such as
-//			-log_backtrace_at=gopherflakes.go:234
-//		a stack trace will be written to the Info log whenever execution
-//		hits that statement. (Unlike with -vmodule, the ".go" must be
-//		present.)
-//	-v=0
-//		Enable V-leveled logging at the specified level.
-//	-vmodule=""
-//		The syntax of the argument is a comma-separated list of pattern=N,
-//		where pattern is a literal file name (minus the ".go" suffix) or
-//		"glob" pattern and N is a V level. For instance,
-//			-vmodule=gopher*=3
