+     "The spectral-cube package provides an easy way to read, manipulate,
+analyze, and write data cubes with two positional dimensions and one spectral
+dimension, optionally with Stokes parameters.
+
+It provides the following main features:
+@itemize
+@item A uniform interface to spectral cubes, robust to the wide range of conventions
+of axis order, spatial projections, and spectral units that exist in the wild.
+@item Easy extraction of cube sub-regions using physical coordinates.
+@item Ability to easily create, combine, and apply masks to datasets.
+@item Basic summary statistic methods like moments and array aggregates.
+@item Designed to work with datasets too large to load into memory.
