OP here. You are right that C++ is moving away from the preprocessor (personally I can't wait for modules to save me from #include hell). CPIP was not intended to advocate advancements in the preprocessor but merely to make preprocessing in either C or C++ more traceable/comprehensible. 'Modern' C++ does not depend so stongly on a preprocessor however C does and most big C projects use all features of the C preprocessor, however opaque. This is why I chose to illustrate CPIP with preprocessing a single file from the linux kernel: http://cpip.sourceforge.net/copy_to_html/cpu/index_cpu.c_9421877faaf4151b78debf7c842685f2.html http://cpip.sourceforge.net/copy_to_html/cpu/index_cpu.c_942...
