+multi-dimensional contiguous and non-contiguous coordinate-aware data arrays.
+
+It combines data, uncertainties, units, metadata, masking, and coordinate
+transformations into classes with unified slicing and generic coordinate
+transformations and plotting/animation capabilities.  It is designed to handle
+data of any number of dimensions and axis types (e.g. spatial, temporal,
+spectral, etc.) whose relationship between the array elements and the real world
+can be described by @acronym{WCS, World Coordinate System} translations.")
