The intention in developing Invicta was not only to get people to use it, but also to have them (well, at least some of them) contribute code parts that will help make it even more useful. This is why Invicta is an open-source project, licensed under LGPL

Feel free to use it in any way not contradicting the LGPL, and if you're feeling extra nice today, there is a lot that can be improved and modified (see the TODO list). Any help will be appreciated.
