+annotations, array-oriented and math-heavy Python code can be just-in-time
+compiled to native machine instructions, similar in performance to C, C++ and
+Fortran, without having to switch languages or Python interpreters.
+
+Numba works by generating optimized machine code using the LLVM compiler
+infrastructure at import time, runtime, or statically (using the included pycc
+tool).")
