I've written an app that takes Hero Lab save files and converts them into tokens for Maptool. The tokens have on them a rich set of macros like attack rolls, saving throw rolls, skill/ability rolls, feats, spells and so on which are taken out from the Hero Lab save files.
Here's a quick video going over the basics of the app.
The app is written in Python, but I have compiled binaries for Linux, Windows and Mac. You can download the app and see some more tutorial vids at the hl2mt project page.
If anyone has any questions or feature requests, please let me know.
Extremely well done. I'm now looking for the source because I'd like to export additional token properties.
