Utility module to convert existing custom blocks to nodes

Hi.
This module is exactly what I need for a site, but I found it after I'd already set up a lot of custom blocks.

Because these already have content, and complex visibility settings, I figured I'd write something to convert them rather than have to do them one by one.

This is a utility module that presents an admin page to pick which custom blocks to convert, and which node type to create them as (from the list of types nodeblock is set to use).
Once the conversion is done, the module can be disabled.

Would you be interested in including it in the nodeblock package as an extra module?

I'm afraid this is only for D5 as the project I'm working on is a D5 site.
(And for my D6 sites I'll know to install nodeblock from the start... :)
