Not that it really fits there either, but I've been trying to keep the
th0?/ directories free from any actual code. They should only contain
the distinct translation units within the original three .EXE binaries,
`#include`ing files from subdirectories, along with maybe game-specific
`#pragma`s, but contain no code on their own. Port authors would simply
ignore those, and link everything from the subdirectories into one
binary. That approach has seemed to make the most sense for all of this
so far.
