The -testcache flag causes clean to expire all test results in the
go build cache.

The -modcache flag causes clean to remove the entire module
download cache, including unpacked source code of versioned
dependencies.

The -fuzzcache flag causes clean to remove files stored in the Go build
cache for fuzz testing. The fuzzing engine caches files that expand

The lines at the top of the script are a sequence of commands to be executed by
a small script engine configured in ../../script_test.go (not the system shell).

The scripts' supporting files are unpacked relative to $GOPATH/src
(aka $WORK/gopath/src) and then the script begins execution in that directory as
well. Thus the example above runs in $WORK/gopath/src with GOPATH=$WORK/gopath

For example, imagine you want to unpack some dependencies and put the unpacked directories and files on the classpath.
You can do so by registering an artifact transform action of type `Unzip`, as shown here:

.Artifact transform registration without parameters

  friend tensorflow::StatusOr<T> Cast(Handle handle);

  friend class UneraseCallHelper;
