 // - main.UseCCache: Whether to use ccache.
 // - main.ConfigName: Name of the configuration to use.
 //   See config.go for the supported values.
-// - main.OldWrapperPath: Path to the old wrapper to compare commands
-//   against. Comparison is deactivated if empty.
 //
 // The script ./build simplifies the call to `go build`.
 // E.g. ./build --use_ccache=true --config=cros.hardened will build a
 // binary that uses the ccache for ChromeOS with hardened flags.
 //
 // Test arguments:
-// - crosroot: Specifies the ChromeOS toolchain root directory (aka chroot).
-//   If this is given, golden tests will compare the produced commands against the
-//   old compiler wrapper.
 // - updategolden: To update the golden results for the wrapper. Without it,
 //   the tests will verify that the wrapper output matches the goldens.
 // - rungolden: To filter the golden tests by a regex for the wrapper env, path and args.
 //
 // Examples:
-// - run all tests and compare golden output against old compiler wrapper:
-// 		go test third_party/toolchain-utils/compiler_wrapper/ -v --crosroot=$HOME/chromiumos/chroot/
 // - run all tests in isolation:
 // 		go test third_party/toolchain-utils/compiler_wrapper/ -v
