+"""Test that about module matches pyproject
+
+Currently poetry does not have a way to access meta info about a module/package
+at runtime from within the package itself (without installing poetry as a dependency
+of every project). To get around this, we could ship the ``pyproject.toml`` along with
+the sdist and wheels, which seems clumsy, or we can create the semi-standard
+``__about__.py`` and enforce consistency through a test that will let us know if the two
+are not equal to each other
