+The "No Language Left Behind" paper is a dataset with translation examples across 200 languages.
+This paper reuses prior work, and for some language pairs is just reusing CC-Matrix published on statmt.org.
+Depending on the language pair chosen, this script will fetch either the original
+version from statmt.org, or the new one from AllenAI.
