+scnlib is a modern C++ library for replacing scanf and std::istream. This
+library attempts to move us ever so much closer to replacing iostreams and C
+stdio altogether. It's faster than iostream (see Benchmarks), and type-safe,
+unlike scanf. Think {fmt} or C++20 std::format, but in the other direction.
+
+This library is the reference implementation of the ISO C++ standards proposal
+P1729 "Text Parsing".
