To add a new Analyzer to an existing driver, add another item to the list:

	import ( "unusedresult"; "nilness"; "printf" )

	var analyses = []*analysis.Analyzer{
		unusedresult.Analyzer,
		nilness.Analyzer,
		printf.Analyzer,
	}

A driver may use the name, flags, and documentation to provide on-line
help that describes the analyses it performs.
The doc comment contains a brief one-line summary,

# Analyzers

The purpose of analyzers is to examine Istio configuration for potential problems that should be surfaced back to the user. An analyzer takes as input a Context object that contains methods to inspect the configuration snapshot being analyzed, as well as methods for reporting any issues discovered.

## Writing Analyzers

### 1. Create the code

	fileExtensions = []string{".json", ".yaml", ".yml"}
)

// Analyze command
func Analyze(ctx cli.Context) *cobra.Command {
	var verbose bool
	analysisCmd := &cobra.Command{
		Use:   "analyze <file>...",
		Short: "Analyze Istio configuration and print validation messages",
		Example: `  # Analyze the current live cluster
  istioctl analyze

  # Analyze the current live cluster for a specific revision

	// in case we encounter them in imported files.
	kept := expand(analyzers)
	for a := range everything {
		if !kept[a] {
			for _, f := range a.FactTypes {
				gob.Register(f)
			}
		}
	}

	return analyzers
}

func expand(analyzers []*analysis.Analyzer) map[*analysis.Analyzer]bool {
	seen := make(map[*analysis.Analyzer]bool)
	var visitAll func([]*analysis.Analyzer)

	factTypes := make(map[reflect.Type]*Analyzer)

	// Traverse the Requires graph, depth first.
	const (
		white = iota
		grey
		black
		finished
	)
	color := make(map[*Analyzer]uint8)
	var visit func(a *Analyzer) error
	visit = func(a *Analyzer) error {
		if a == nil {
			return fmt.Errorf("nil *Analyzer")
		}
		if color[a] == white {
			color[a] = grey

			// names
