Indeed, we wrote much more code in python than we were expecting, including all in-game screens and the main interface.

(Note that I'm explicitly avoiding use of the more familiar term binary distribution.

A third area of work is one automatic generation of scripting language interfaces to low-level code such as C, C++, or Java. The SWIG...
