preprocessor

Anyone who has ever read a piece of C source code has seen them—the preprocessor directives. For example, you can find include directives (#include) at the beginning of most source files. The preprocessor is a system that rewrites the source before the actual compiler sees it. Clearly, this is a very powerful tool—the downside is that you could accidentally shoot yourself in the foot.
