+## Overview
+During the C++20 cycle [P0052 Generic Scope Guard and RAII Wrapper for the Standard Library](https://wg21.link/P0052) added 4 types: `scope_exit`, `scope_fail`, `scope_success` and `unique_resource` to [LTFSv3](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2022/n4908#scopeguard).  In the intervening time, two standard libraries have implemented support as well as Boost. With the imperative for safety and security in C++ developers need every tool in the toolbox. The authors believe it is time to move this facility into the standard.  The paper will re-examine the five year old design and any learning from deployment of the LTFSv3.

 `beman.scope` is a minimal C++ library conforming to [The Beman Standard](https://github.com/bemanproject/beman/blob/main/docs/BEMAN_STANDARD.md).
 This can be used as a template for those intending to write Beman libraries.
 It may also find use as a minimal and modern  C++ project structure.
