   3     MoinMoin - Parser for CSV data
   4 
   5     This is just a copy of the old CSV processor.
   6     I think it is intended as an example, cause it
   7     lacks to flexibility to read arbitary csv dialects.
   8 
   9     Perhaps this should be rewritten using another CSV lib
  10     because the standard module csv does not support unicode.
