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.
