/**
 * @assertion Future<Link> create(
 *  String target, {
 *  bool recursive: false
 *  })
 * Creates a symbolic link. Returns a Future<Link> that completes with the link
 * when it has been created. If the link exists, the future will complete with
 * an error.
 *
 * If recursive is false, the default, the link is created only if all
 * directories in its path exist. If recursive is true, all non-existing path
 * components are created. The directories in the path of target are not
 * affected, unless they are also in path.
 *
 * On the Windows platform, this call will create a true symbolic link instead
 * of a Junction. In order to create a symbolic link on Windows, Dart must be
 * run in Administrator mode or the system must have Developer Mode enabled,
 * otherwise a FileSystemException will be raised with ERROR_PRIVILEGE_NOT_HELD
 * set as the errno when this call is made.
 *
 * On other platforms, the posix symlink() call is used to make a symbolic link
 * containing the string target. If target is a relative path, it will be
 * interpreted relative to the directory containing the link.
 *
 * @description Checks that on the Windows platform relative paths to the target
 * is not converted to absolute paths (as it was in the past)
