DESCRIPTION

       This  program  converts  a  C  program  to  use trigraphs.  A trigraph is a three character sequence that
       encodes a single character.  A trigraph begins with two question marks.  The third character is `/'  (the
       trigraph  means  `\'), '(' (`['),  ')' (`]'),  '<' (`{'),  '>' (`}'),  '!' (`|'),  ''' (`^'),  '-' (`~'),
       '=' (`/'), or '/' (`\').
