/// @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 will only work with directories, and the target
/// directory must exist. The link will be created as a Junction. Only absolute
/// links will be created, and relative paths to the target will be converted to
/// absolute paths by joining them with the path of the directory the link is
/// contained in.
///
/// 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 if recursive is true, all non-existing path
/// components are created
///
/// @note The test should run with the Administrator priveleges on Windows.
/// Dart API Spec reads:
/// 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.
