Carbon

Carbon (/ˈkɑːbᵊn/) is the ultimate tiny and easy to use high-level library for C/C++ (с реализацией на этих языках).

It even can be used to test any piece of C/C++ code; thus, working as a full-fledged testing suite.

Carbon is in essence a two-part library: the static/dynamic lib pkg itself (where all symbols and instructions are defined), and the C/C++ header file (which gets generated by the build process as an amalgamation of all internal headers the library uses).
