[Biocorba-l] Re: Migrating to biocorba 2

[Jason Stajich]

Harold, 

Many of these questions ought to be posed to the entire biocorba list as
well as some people may be better qualified to comment on them than me.  
I am CCing them. I'll try and respond to the questions later on when I get
a chance.  You may want to subscribe to the biocorba list as well.
