CompPad is an OpenOffice / LibreOffice extension for performing units-aware engineering calculations within a Writer document, allowing calculations to be documented using all of the resources of Writer. It has functionality similar to Mathcad®, but is not intended to be a Mathcad® clone. Rather, I hope it might prove more flexible and extensible, and that it might encourage other free / open-source alternatives to a proprietary engineering "Killer App."

Great project.
Perhaps you already thought about it, but what about integration with Maxima ? Would it be useful?

Anyway, thanks for your work!
