I don't know yet whether it will be possible to wrap the new engine to work with the existing GUI. If it is, it will take some effort.
I started by working on a system file reader implementation, which is almost done. There is also a basic implementation of the output layer, and a basic implementation of a syntax parser. And several tests. None of it is really ready and I don't know when it will be, but when it is, it won't have segfaults.
