+    (description "@code{IdentityRanges} are Julia-language a helper type for
+creating \"views\" of arrays.  They are a custom type of AbstractUnitRange that
+makes it easy to preserve the indices of array views.  The key property of an
+@code{IdentityRange r} is that @code{r[i] == i} (hence the name of the
+type/package), and that they support arbitrary start/stop indices (i.e., not
+just starting at 1).")
