### Writing plugins in C++
When including headers from ClassiCube, they **must** be surrounded with `extern "C"`, i.e.
```C
extern "C" {
#include "src/Chat.h"
#include "src/Game.h"
#include "src/String.h"
}
```
Otherwise you will get obscure `Undefined reference` errors when compiling.
Exported plugin functions **must** be surrounded with `extern "C"`, i.e.
