 ``pyrefcount`` provides a simple API for reference counting, providing protected access to reference counted values,
 and for allowing acquire/release actions to be carried out when a reference count becomes active, or the last user
 drops off, respectively. ``pyrefcount`` is inspired by the Linux Kernel's `refcount_t`_ API.
