+"""C interfacing code.
+
+This namespace contains everything that interacts with C code.
+Most C related object are ctypes compatible, which means
+they contains a handle field that is ctypes.c_void_p and can
+be used via ctypes function calls.
+
+Some performance critical functions are implemented by cython
+and have a ctypes fallback implementation.
