...building For practical reasons, we propose to use an existing programming language. The design and implementation of a new language can take several years, and we have picked one that is good enough to start working on the other three points. Our choice is Python, an advanced scripting and prototyping language. There is enough (anecdotal) evidence that Python is easy to learn for people who are (nearly) computer-illiterate. There are currently no development tools or training m...
