Interop.
libcyber allows Cyber to be embedded into your applications.<br>Cyber's CLI and core library were built using libcyber.
The FFI API allows your scripts to use any C-ABI compatible library.<br>cbindgen.cy was also created as a tool to automatically generate full bindings from just a C header file. Some example bindings include Raylib and LLVM.
