// - main.UseCCache: Whether to use ccache.
// - main.ConfigName: Name of the configuration to use.
// See config.go for the supported values.
//
// The script ./build simplifies the call to `go build`.
// E.g. ./build --use_ccache=true --config=cros.hardened will build a

//
// Test arguments:
// - 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 in isolation:
// go test third_party/toolchain-utils/compiler_wrapper/ -v
