// Package gutil is a replacement for ioutil, which should not be used in new
// code as of Go 1.16. With Go 1.16 and higher, this implementation
// uses the ioutil replacement functions in "io" and "os" with some
// Gomega specifics. This means that we should not get deprecation warnings
// for ioutil when they are added.
