2 /* Capsule objects let you wrap a C "void *" pointer in a Python
3 object. They're a way of passing data through the Python interpreter
4 without creating your own custom type.
5
6 Capsules are used for communication between extension modules.
7 They provide a way for an extension module to export a C interface
8 to other extension modules, so that extension modules can use the
9 Python import mechanism to link to one another.

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