+     "@code{seqsplit} provides a command @code{\\seqsplit}, which makes its
+argument splittable anywhere, and then leaves the TeX paragraph-maker to do the
+splitting.  The package is suitable for situations when one needs to type long
+sequences of letters or of numbers in which there is no obvious break points to
+be found, such as in base-sequences in genes or calculations of transcendental
+numbers.  While the package may obviously be used to typeset DNA sequences, the
+user may consider the @code{dnaseq} as a rather more powerful alternative.")
