This allows intermediate build artifacts to be cleaned up without specifying them individually as BYPRODUCTS. When building a data file <name>, all files are first built under tmp/<name> before the target itself is moved from tmp/<name>/<name> to Packaged/<name>. add_house_file() could also be modified in this way, but it wouldn't reduce the boilerplate by much, so it's probably not worth it.
About Aerofoil
Aerofoil is a port of John Calhoun's Glider PRO, the classic paper airplane game for Apple Macintosh computers released in 1994.
The port features a 90's-style GUI, gamepad support, high-quality upscaling and color correction, a full port of the level editor, a set of import tools for unpacking and converting the vast majority of existing community content, and a new touchscreen interface for mobile devices.
