     * You can combine this method with the {@link #copy(Action)}
     * method to untar a TAR file:
     *
     * <pre class='autoTested'>
     * task untar(type: Copy) {
     *   from tarTree('someCompressedTar.gzip')
     *
     *   //tar tree attempts to guess the compression based on the file extension
