20 /** Insertion of accents
22 Proper handling of accented characters.
23 This is class is supposed to handle all LaTeX accents, it
24 is also possible that the class will change a bit so that
25 it also can handle other special characters (e.g. Hstroke)
26 Initiated by Ivan Schreter, later modified by Lgb.
