I have read the documentation for the library, and browsed through the test code. Based on that I recommend acceptance of the circular buffer library. Nice work Jan! Here are some suggestions. This sentences seems unnecessary: In fact the circular_buffer is defined in the file boost/circular_buffer/base.hpp, but it is necessary to include the boost/circular_buffer.hpp in order to use this container Have you checked whether CopyConstructible is in fact the only requirements needed on the type parameter T? For example, I bet T must also be Assignable. But who knows what other requirements you may have missed (it is easy to miss them). I recommend using concept archetypes to check this. There are no requirements on the Alloc type parameter. Surely there should be some. I'm not a big fan of how the semantics section is separated from the function prototypes. I'd rather see all the information about a function in one place. Also I'm not fond of how the "source code documentation" is separate from the main documentation. I had to click around a lot to find information. Best wishes, Jeremy
