+in LaTeX.  Arrays can contain characters as well as TeX and LaTeX commands,
+nesting of arrays is possible, and arrays are processed within the same brace
+level as their surrounding environment.  Array levels can be delimited by
+characters or control sequences defined by the user.  Practical uses of this
+package include data management, construction of lists and tables, and
+calculations based on the contents of lists and arrays.")
