+     "The purpose of this package is to decrease the number of keystrokes
+needed to typeset small amounts of aligned material (matrices, arrays, etc.).
+It provides a facility for typing alignment environments and macros with
+spaces as the alignment delimiter and semicolons (by default) as the
+end-of-row indicator.  This package also contains utility macros for
+typesetting augmented matrices, vectors, arrays, systems of equations, and
+more, and is easily extendable to other situations that use alignments.
+People who have to typeset a large number of matrices (like linear algebra
+teachers) should find this package to be a real time saver.")
