/* 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.
