This service exists mainly as a way to demonstrate how you can add new stages to Aleph's document processing, especially for NLP.
See: https://docs.aleph.occrp.org/developers/adding-text-processors/
IMPORTANT: this is not meant to be a working implementation of translation for Aleph. If you want to fix it up to be production-grade, that would be great. But don't run it in prodcution like this, please.
