+ (description "A block array is a partition of an array into blocks or
+subarrays. This package has two purposes. Firstly, it defines an interface for
+an @code{AbstractBlockArray} block arrays that can be shared among types
+representing different types of block arrays. The advantage to this is that it
+provides a consistent API for block arrays.
+Secondly, it also implements two different type of block arrays that follow the
+@code{AbstractBlockArray} interface. The type @code{BlockArray} stores each
+block contiguously while the type @code{PseudoBlockArray} stores the full matrix
+contiguously. This means that @code{BlockArray} supports fast non copying
+extraction and insertion of blocks while @code{PseudoBlockArray} supports fast
+access to the full matrix to use in in for example a linear solver.")
