Rubotz is a code generator and compiler wrapper for NXC, a language
for Lego Mindstorms NXT robots. This is a proof-of-concept release
which supports only one sensor and a subset of available motor
functionality.
Using the library it is currently possible to write and compile
programs for Lego Mindstorms NXT robots entirely in Ruby. Better
support for sensors, motors, and multi-threading should appear in
future releases.
