       @resolved_tags=get_external_clusters(@tags)
           Use an external script to resolve @tags into hostnames.

       $cluster->get_tag_entries($filename);
           Read in /etc/tags, $HOME/.clusterssh/tags and any other given file name and register the tags found.

       $cluster->read_cluster_file($filename);

       $cluster->expand_filename($filename);
           Expand ~ or $HOME in a filename

       $cluster->read_tag_file($filename);
           Read in the given tag file and register the tags found

       $cluster->register_tag($tag,@hosts);

       $cluster->register_host($host,@tags);
           Register the given host on the provided tags.

       %tags = $cluster->dump_tags();
           Returns a hash of all tag data.

       @tags = $cluster->expand_glob( $type, $name, @items );
           Use shell expansion against each item in @items, where $type is either 'node', or 'tag' and $name  is
