      Hammer is a parsing library. Like many modern parsing libraries, it
      provides a parser combinator interface for writing grammars as inline
      domain-specific languages, but Hammer also provides a variety of parsing
      backends. It's also bit-oriented rather than character-oriented, making it
      ideal for parsing binary data such as images, network packets, audio, and
      executables.
