The material of this document comes from the introduction to the library that
had been lost in the move away from CWEB (formerly tl/cc/main.web).
This file gives a good overview of the library. It has been adapted from TeX to
LaTeX. Also I fixed a mistake in the Faà di Bruno's tensor formula.
Note that dynare++ will only be built if configure finds ctangle, blas, lapack and pthreads
