i dont think such software is available if available,then why people hiring directory subimters on different forums.........
There are a lot of directory submission network that offer such service but you have to buy their software. Just try googling with the right keyword like "Automatic Directory Submission Software". But my best advice is to not resort on this automatic service as the network of directories are not maintained as individual quality directories but for the purpose of link farming which is often being penalized by SE especially by Google.
Well, as a webmaster you've been missing something if you don't know. They were been around since link buying was still up. Say phpdirsubmit.com has the top demands for such software.
Why didn't I think of that earlier. Brilliant As others have said you should submit manually it is far better to submit ten a day over time than 2000 in one day, your SEO needs to be natural of Google will jump up and down on your bones
