NAME

Bio::TreeIO - Parser for Tree files

SYNOPSIS

  {
      use Bio::TreeIO;
      my $treeio = new Bio::TreeIO('-format' => 'newick',
                                   '-file'   => 'globin.dnd');
      while( my $tree = $treeio->next_tree ) {
          print "Tree is ", $tree->size, "\n";
      }
  }

DESCRIPTION

This is the driver module for Tree reading from data streams and flatfiles. This is intended to be able to create Bio::Tree::TreeI objects.
