 It is common to pre-compute arguments to :func:`setup`, to better structure the
 driver script. In the example above, the\ ``ext_modules`` argument to
 :func:`setup` is a list of extension modules, each of which is an instance of

 In many cases, building an extension is more complex, since additional
 preprocessor defines and libraries may be needed. This is demonstrated in the

 The cycle detector is able to detect garbage cycles and can reclaim them so long

 When there are such finalizers, the detector exposes the cycles through the

 detector is considered an optional component; though it is included by default,
 it can be disabled at build time using the :option:`--without-cycle-gc` option
