/// @assertion String resolveSymbolicLinksSync()
/// Resolves the path of a file system object relative to the current working
/// directory, resolving all symbolic links on the path and resolving all .. and
/// . path segments.
///
/// resolveSymbolicLinksSync uses the operating system's native file system API
/// to resolve the path, using the realpath function on linux and OS X, and the
/// GetFinalPathNameByHandle function on Windows. If the path does not point to
/// an existing file system object, resolveSymbolicLinksSync throws a
/// FileSystemException.
///
/// On Windows the .. segments are resolved before resolving the symbolic link,
/// and on other platforms the symbolic links are resolved to their target before
/// applying a .. that follows.
/// @description Check that a FileSystemException is thrown if the path does not
/// point to an existing file system object.
