-## Combining C and ƿit
-
-A common pattern is to have a C file provide low-level functions and a `.cm` file provide a higher-level API:
-
-```c
-// _vector_native.c
-// ... raw C functions ...
-```
-
-```javascript
-// vector.cm
-var native = this  // C module passed as 'this'
-
-var Vector = function(x, y) {
-  return {x: x, y: y}
-}

-Vector.length = function(v) {

-Vector.normalize = function(v) {
