The trouble with wrapping this is, that there is no API. There is the main function and all other functions are kind of private. Main reads tons of parameters via stdin and textfiles, calculates and writes to stdout and text files.
Instead of a wrapper, you need to implement a string generator + parser in order to use it.
I did this with similar codes before. It is also a tedious and buggy process as the string formats are not precisely specified and meant for humans instead of machines.
So before going through this again, I thought maybe I could translate the code and skip the intermediate string form.
