+The Smith-Waterman algorithm performs local sequence alignment; that is, for
+determining similar regions between two strings of nucleic acid sequences or
+protein sequences. Instead of looking at the entire sequence, the
+Smith-Waterman algorithm compares segments of all possible lengths and
+optimizes the similarity measure.  Gotoh and Atschul added optimizations making
+it practical for larger problems.
