Just a quick announcement: The 2nd edition of my book "The Boost C++ Libraries" is available.

- It introduces 72 Boost libraries.

Awesome work, Boris.

Thank you!

I'm very happy to see a small chapter on ptr_container. It's good that you compare it with container.

Comment 1: I would prefer examples with unique_ptr to use make_unique.

Comment 2: The are two major other difference betweeen ptr_vector<T> and vector:

A. No element can be null(by default), this can never be guranteed with vector, as you can just move en element out or push_back a null.

B. Automatic cloning: ptr_containers can be copy'ed, performing a deep clone of the elements.

Thanks, it is super useful to get this extra information from library authors/maintainers as I need to divide my attention across too many libraries. I'll note this down so that I don't forget it. :) Boris
