The `assemble` script runs the assembly source through Merlin32, then changes the ProDOS file kind to `S16`, an executable format that is used for GS/OS applications. `_FileInformation.txt` is what `cadius` uses to manage the ProDOS metadata for each record (since obviously this information can't be mapped to your computer's filesystem).
