+ CObjects are marked Pending Deprecation as of Python 2.7.
+ The full schedule for 2.x is as follows:
+ - CObjects are marked Pending Deprecation in Python 2.7.
+ - CObjects will be marked Deprecated in Python 2.8
+ (if there is one).
+ - CObjects will be removed in Python 2.9 (if there is one).
+
+ Additionally, for the Python 3.x series:
+ - CObjects were marked Deprecated in Python 3.1.
+ - CObjects will be removed in Python 3.2.
+
+ You should switch all use of CObjects to capsules. Capsules
+ have a safer and more consistent API. For more information,
+ see Include/pycapsule.h, or read the "Capsules" topic in
+ the "Python/C API Reference Manual".
+
+ Python 2.7 no longer uses CObjects itself; all objects which
+ were formerly CObjects are now capsules. Note that this change
+ does not by itself break binary compatibility with extensions
+ built for previous versions of Python--PyCObject_AsVoidPtr()
+ has been changed to also understand capsules.

+/* C objects to be exported from one extension module to another.

+ They provide a way for an extension module to export a C interface
+ to other extension modules, so that extension modules can use the
+ Python import mechanism to link to one another.
