How does ntf core fit in the existing Open Source world?

How does this compare with ASIO? How does it compare with Sender/Receiver? Is this just an allocator aware version of ASIO? I'd like to understand why someone would want to adopt this library as opposed to one of the more popular alternatives. Ideally this would be in the front page docs.

Start with the front-page documentation and the library's existing description of its asynchronous networking features. Research how ntf core compares with ASIO and Sender/Receiver, including whether allocator awareness is a meaningful distinction. Done means the front page explains the relevant differences and why someone might adopt ntf core instead of those alternatives.
