 // The traditional error handling idiom in Go is roughly akin to

-//     }
+//	if err != nil {
+//	        return err

 //
 // which when applied recursively up the call stack results in error reports
 // without context or debugging information. The errors package allows
 // programmers to add context to the failure path in their code in a way
 // that does not destroy the original value of the error.
 //
-// Adding context to an error
+// # Adding context to an error
 //
 // The errors.Wrap function returns a new error that adds context to the
 // original error by recording a stack trace at the point Wrap is called,
 // together with the supplied message. For example
 //
-//     _, err := ioutil.ReadAll(r)
-//     if err != nil {
-//             return errors.Wrap(err, "read failed")
-//     }
+//	_, err := ioutil.ReadAll(r)
+//	if err != nil {
+//	        return errors.Wrap(err, "read failed")
+//	}
 //
 // If additional control is required, the errors.WithStack and
 // errors.WithMessage functions destructure errors.Wrap into its component
 // operations: annotating an error with a stack trace and with a message,
 // respectively.

 // the topmost error that does not implement causer, which is assumed to be

 //
-//     switch err := errors.Cause(err).(type) {
-//     case *MyError:
-//             // handle specifically
-//     default:
