[BioPython] Could BioPython transfer GenBank file to Fasta file like BioPerl?

We do have a FormatIO system under development which is meant to act
much like the BioPerl SeqIO system and make simple format
conversions much easier.

I wrote up some cookbook style documentation for the system (and for
the "by hand" system) you describe above. You can get them from the
documentation page:

http://biopython.org/documentation/

under "Cookbook-style documentation" and "Converting GenBank (and
other formats) to Fasta."

Hopefully this is helpful -- please let me know if there are any
questions or I can improve the docs. Thanks!
