/* 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. | |
