 The cycle detector is able to detect garbage cycles and can reclaim them.
 The :mod:`gc` module exposes a way to run the detector (the
 :func:`~gc.collect` function), as well as configuration
-interfaces and the ability to disable the detector at runtime.  The cycle
-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
-to the :program:`configure` script on Unix platforms (including Mac OS X).  If
-the cycle detector is disabled in this way, the :mod:`gc` module will not be
-available.
