The `value` of that map entry is the **mode** of what `astyle` accept, only these modes are available for now: **c**, **cs**, and **java**. (refer: http://astyle.sourceforge.net/astyle.html#_mode).

The mode is not the **syntax** of that language, it just tell what astyle should do. With a barely knowledge of  the processing language, I can only figure out **it looks like java** (similarity, from my perceptive, more than c and cs).
