       Bio::CodonUsage::IO - for reading and writing codon usage tables to file


         use Bio::CodonUsage::IO;

         ## read in a codon usage file
         my $io = Bio::CodonUsage::IO->new(-file => "in");
         my $cut = $io->next_data();

         ## write it out again
         my $out = Bio::CodonUsage::IO->new(-file => ">out");


       This class provides standard IO methods for reading and writing text files of codon usage
       tables. These tables can initially be retrieved using Bio::DB::CUTG. At present only this
       format is supported for read/write.

       Reading a CUTG will return a Bio::CodonUsage::Table object.
