* To run demos do::

    cd Demos
    make test

  which runs run_primes.py, run_numeric_demo.py, run_spam.py,
  integrate_timing.py, callback/runcheese.py and embed/embedded

* For other demos::

    cd libraries
    python setup.py build_ext --inplace
    python -c 'import call_mymath;print(call_mymath.call_sinc(1))'

  To run one of the benchmarks for 10 iterations to compare cython and python timings::

    cd benchmarks
    python setup.py build_ext --inplace
    python nqueens.py -n 10
    python -c 'import nqueens;print(nqueens.test_n_queens(10))'

  To demo cython/bin/cython_freeze::

    make
    ./nCr 10 5
    ./python

* Build notes

  * benchmarks/chaos.py requires cython 0.24 or newer

  * embed and freeze work for python2, require cython 0.24 or higher
    for python 3.5
