/* Capsule objects let you wrap a C "void *" pointer in a Python

   object.  They're a way of passing data through the Python interpreter

   without creating your own custom type.

   Capsules are used for communication between extension modules.

   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.

   For more information, please see "c-api/capsule.html" in the

   documentation.
