+These directories exist in order to make this Basis Universal insanity
+
+```cpp
+#include "../zstd/zstd.h"
+```
+
+actually include an external Zstd installation. I.e., an up-to-date version
+with all SECURITY FIXES and OPTIMIZATIONS that happened since the original file
+was put in the Basis repository in April 2021. The `put-this-on-include-path/`
+subdirectory is added to the include path, which then makes `../zstd/zstd.h`
+point to the `zstd.h` file in the `zstd/` subdirectory here. That file then
+uses `#include <zstd.h>` (with `<>` instead of `""`) to include the external
+`zstd.h` instead of the bundled file.
+
+The real fix is in https://github.com/BinomialLLC/basis_universal/pull/228,
+waiting to get some attention since December 2021. Haha.
