Bio::FlatFile.auto(ARGF) do |ff|
  ff.each_entry do |gb|
    # genbank/genbank.rb
    p gb.entry_id
    p gb.length
    p gb.strand
    p gb.natype
    p gb.circular
    p gb.division
    p gb.date
    p gb.basecount

    # genbank/common.rb
    p gb.definition
    p gb.versions
    p gb.accessions
    p gb.acc_version
    p gb.accession
    p gb.version
    p gb.gi
