+// 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.
