sl@0: This class is a low-level class for bi-directionally reordering text. It 
sl@0: allows the re-ordering of text using no leaving functions at all, and provides 
sl@0: a finer degree of control than TBidiText. However, it should not be used 
sl@0: without understanding the basics of the Unicode Bi-directional Reordering 
sl@0: Algorithm.
