I need to update it, but here is a short doc:

If you look at the hg repo, you will see a few interesting exercises.

accumulator shows the idea of making 1-d numpy arrays usable as containers
compatible with boost::range.

numpy_iter.hpp has most of the work.  This has:

n-dim wrapper for numpy array, and iterator to go with it.  Since the n-d
iter concept is not too well defined, I haven't worked on this much.

1-dim wrapper and iterator to go with it.

numpy is run-time polymorphic, which the c++ code I want to use is
compile-time.  misc has some tests of dispatching based on types.

num2.cc has some tests of creating numpy arrays.

limit.cc has a little test of ufunc.
