[BioPython] public Smith-Waterman implementation?

[Joanne Adamkewicz]

Hi all,

A non-python related question, but very much in biocomputing:

Can someone point me to a publicly available implementation of the
Smith-Waterman algorithm?  I'm aware of wise2
(http://www.ebi.ac.uk/Wise2/doc_wise2.html), but it implements swp
(protein-protein) only.  I'm looking for something that also includes tswn
and the others.

Thanks in advance for any help,
Joanne
