       Bio::AlignIO::mega - Parse and Create MEGA format data files


           use Bio::AlignIO;
           my $alignio = Bio::AlignIO->new(-format => 'mega',
                                          -file   => 't/data/hemoglobinA.meg');

           while( my $aln = $alignio->next_aln ) {
           # process each alignment or convert to another format like NEXUS


       This object handles reading and writing data streams in the MEGA format (Kumar and Nei).
