      Spicy is a parser generator that makes it easy to create robust C++
      parsers for network protocols, file formats, and more. Spicy is a bit
      like a "yacc for protocols", but it's much more than that: It's an
      all-in-one system enabling developers to write attributed grammars that
      describe both syntax and semantics of an input format using a single,
      unified language. Think of Spicy as a domain-specific scripting language
      for all your parsing needs.
