+Xarray introduces labels in the form of dimensions, coordinates and attributes
+on top of raw NumPy-like arrays, which allows for a more intuitive, more
+concise, and less error-prone developer experience.  The package includes a
+large and growing library of domain-agnostic functions for advanced analytics
+and visualization with these data structures.")
