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