-From the
-[`tree(1)` release notes](https://oldmanprogrammer.net/source.php?dir=projects/tree/CHANGES),
-version 2.0.0:
-
-> - Output un-indented JSON on file descriptor 3 ("stddata") automatically if
->   file descriptor 3 is present (currently Linux only.) Maybe switch to BSON.
-
-Surely, nothing will happen if I just assume that the existence of a specific
-file descriptor implies something, as nobody is crazy or stupid enough to
-hardcode such a thing? **_\<insert sounds of cars crashing in the
-background\>_**
-
-Oops (from the `tree`version 2.0.2 release notes):
-
-> - Okay, apparently the stddata addition is causing havoc (who knew how many
->   scripts just haphazardly hand programs random file descriptors, that's
->   surely not a problem.) Going forward the stddata option will only work if
->   the environment variable STDDATA_FD is present or set to the descriptor to
->   produce the JSON output on.
-
-Assuming anything about the users environment is and will always be a mistake.
-But it's still cool we can have `tree` output structured data using
-`STDDATA_FD`:
-
-```json
-> STDDATA_FD=1 tree
-
-[{"type":"directory","name":".","contents":[{"type":"file","name":"2024-01-01-test.md"},{"type":"file","name":"2024-03-04-htmnix.md"},{"type":"file","name":"2024-04-02-cosmic-drift.md"},{"type":"file","name":"2024-04-15-nix-iceberg.md"},{"type":"file","name":"2024-05-20-swap-i.md"},{"type":"file","name":"2024-09-30-gitignore.md"},{"type":"file","name":"2025-06-05-why-cores.md"},{"type":"file","name":"2025-06-09-nginix.md"},{"type":"file","name":"2025-06-20-intro-cab.md"},{"type":"file","name":"2025-07-04-derive-broken.md"},{"type":"file","name":"2025-07-20-no-gnulib.md"},{"type":"file","name":"_data.ts"}]},{"type":"report","directories":1,"files":12}]
