iFiction
“iFiction” files are metadata tags used by multi-interpreters like Zoom for the Mac, helping to create an iTunes-like frontend to playing IF games. While not officially supported by Hugo (there isn’t a way to automatically generate them like TADS or Inform can), one can manually write .ifiction files, which should then be distributed with your game (the name of the .ifiction file should be the same as the game file).
.ifiction example
Here is an example .ifiction file for the game “Party Arty- Man of La Mancha”:
