# zantetsu-trainer — DEPRECATED

**This crate is unmaintained and will receive no further updates.**

The ML training infrastructure it contained was removed in zantetsu 0.2,
which dropped all ML dependencies in favour of a pure heuristic parser.
There is no replacement for `zantetsu-trainer` — the workflow it powered
is no longer needed.

## Migration

Remove `zantetsu-trainer` from your `Cargo.toml`.

If you were using zantetsu for anime filename parsing, switch to
[`zantetsu 0.2`](https://crates.io/crates/zantetsu):

```toml
[dependencies]
zantetsu = "0.2"
```
