	Translation dataset based on the data from statmt.org.

	Versions exist for different years using a combination of data
	sources. The base `wmt` allows you to create a custom dataset by choosing
	your own data/language pair. This can be done as follows:

	```python
	from datasets import inspect_dataset, load_dataset_builder

	inspect_dataset("wmt18", "path/to/scripts")
	builder = load_dataset_builder(
	"path/to/scripts/wmt_utils.py",
	language_pair=("fr", "de"),
	subsets={
	datasets.Split.TRAIN: ["commoncrawl_frde"],
	datasets.Split.VALIDATION: ["euelections_dev2019"],
	},
	)

	# Standard version
	builder.download_and_prepare()
	ds = builder.as_dataset()

	# Streamable version
	ds = builder.as_streaming_dataset()
	```

	An example of 'validation' looks as follows.
	```

	```

	### Data Fields

	The data fields are the same among all splits.

	#### cs-en
	- `translation`: a multilingual `string` variable, with possible languages including `cs`, `en`.
