== Description ==

To re-use external code in a program, the corresponding header file must be pasted in. This is handled by the compiler when it reaches an `#include` directive.

To include a standard library file, try `#include <foo.h>`.

{{{
#include <stdio.h>

int main() {
    printf("Hello World!\n");
    return 0;
}
}}}

To include a user-created file, try `#include "foo/bar.h"`. The compiler searches for this file in the current directory first, then scans search paths.
