      This library actually doesn't implement the lexer itself. All it does is to
      provide an interface to pre-existing lexical analyzers. Currently it's using
      Ben Hansons excellent <a href="http://www.benhanson.net/lexertl.html" target="_top">Lexertl</a>
      library (proposed for a Boost review, BTW) as its underlying workhorse.

      directly, alw
