SWI-Prolog -- Summary of files

The following files are provided:

SWI-cpp2.h Include this file to get the C++ API. It automatically includes SWI-cpp2-plx.h but does not include SWI-cpp2.cpp.
SWI-cpp2.cpp Contains the implementations of some methods and functions. It must be compiled as-is or included in the foreign predicate's source file. Alternatively, it can be included with each include of SWI-cpp2.h with this macro definition:
```
    #define _SWI_CPP2_CPP_inline inline
    
```
SWI-cpp2-plx.h Contains the wrapper functions for the most of the functions in SWI-Prolog.h. This file is not intended to be used by itself, but is #included by SWI-cpp2.h.
SWI-cpp2-atommap.h Contains a utility class for mapping atom-to-atom or atom-to-term.
test_cpp.cpp, test_cpp.pl Contains various tests, including some longer sequences of code that can help in understanding how the C++ API is intended to be used. In addition, there are test_ffi.cpp, test_ffi.pl, which often have the same tests written in C, without the C++ API.
