    longDescription = ''
      Trealla is a compact, efficient Prolog interpreter with ISO Prolog
      aspirations.
      Trealla is not WAM-based. It uses tree-walking, structure-sharing and
      deep-binding. Source is byte-code compiled to an AST that is interpreted
      at runtime. The intent and continued aim of Trealla is to be a small,
      easily ported, Prolog core.
      The name Trealla comes from the Liaden Universe books by Lee & Miller
      (where it doesn't seem to mean anything) and also a reference to the
      Trealla region of Western Australia.
