Pairwise protein align. program wanted

[Morten Stig Andersen]

I am looking for a freeware pairwise alignment program (for unix) which
can report percent similarity as well as percent identity, like the
'bestfit' and 'gap' programs in GCG. 

I have Bill Pearson's 'align' program, but it reports identity only.

Any clues?

Thanks,

Morten Andersen
