        Hi Sam,   
      
   To generate a parser You must have a very exact grammar. It is not   
   allways available. For example every grammar for Delphi I found in NET   
   is incomplete and/or erroneous. For example the preprocessor   
   directives aren't described.  So I made my Delphi-parser manually   
   testing it on several projects. So I discovered hundreds of errors in   
   the grammar which I used initially.   
      
   Good look
