    * `original.py` were written during development to test all features as they were added.
    * `autogenerated.py` is from the language-independent testing suite ([histogrammar-multilang](https://github.com/histogrammar/histogrammar-multilang)), which provides greater coverage, value-explicitness in the test script, and cross-language agreement.
    * `testnumpy.py` tests numerical agreement between the conventional implementation and the Numpy implementation, which are very different. Also tests much larger datasets and infinity/NaN handling.
+     * contrary to its name, `testnumpy.py` also compares its implementation with the literal code given in [the specification](http://histogrammar.org/docs/specification/) as well.
 
 Primitive implementation is mature. Notes in the "Numpy" column are rough speedup factors for a range of tests.
