| + | Mer needs new control panels. But not everyone knows C, but they may be proficient in C#. Vala is a language with C#-like syntax, that compiles to C, which makes it perfect for writing CPAs which are (to my knowledge) C only. |
| | + | But, documentation on Vala is rather lacking. |

| | Save the above as "cpa.vala". Because valac seems to be more accustomed for making programs, you have to use valac's -C option which'll output the generated C code and gcc can then be used to make it into a library. | | Save the above as "cpa.vala".
