Is the tool available from somewhere?

Not yet. It is still very alpha. I basically want to gauge peoples' interest. In the past I've spent a lot of time setting up open source projects only to get hardly any use or feedback. In addition, I am self employed, so just giving away a potentially very valuable tool may not be a great use of my dev time.

Perhaps a business model to consider is making the macro expander free and open, then selling actual macros that do stuff. This way 3rd parties can write their own macros as well.
