      GObject introspection is a middleware layer between C libraries (using
      GObject) and language bindings. The C library can be scanned at compile
      time and generate a metadata file, in addition to the actual native C
      library. Then at runtime, language bindings can read this metadata and
      automatically provide bindings to call into the C library.
