  parser
       
           An algorithm or program to determine the
          syntactic structure of a sentence or string of symbols in some
          language.  A parser normally takes as input a sequence of
          tokens output by a lexical analyser.  It may produce some
          kind of abstract syntax tree as output.  One of the best
          known parser generators is yacc.
