Conversão de RTF para TEXTO usando perl

Alguém pode me dizer como podemos converter o arquivo rtf em texto com todas as tags, tabelas e dados formatados usando a linguagem de programação perl?

@ Ahmad Bilal, @ petersergeant: Eu tenho usado o código abaixo para conversão de RTF para TXT e sou capaz de converter em texto. Mas o problema é que não consigo capturar os formatos de tabela ou imagem e mesmo todas as entidades no arquivo de entrada não são capturadas usando o programa.

use 5.8.0;
use strict;
use warnings;
use Getopt::Long;
use Pod::Usage;
use RTF::HTMLConverter;
