3
4 Capsule objects let you wrap a C "void *" pointer in a Python
5 object. They're a way of passing data through the Python interpreter
6 without creating your own custom type.
7
8 Capsules are used for communication between extension modules.
9 They provide a way for an extension module to export a C interface
10 to other extension modules, so that extension modules can use the
11 Python import mechanism to link to one another.
12
13 This was introduced in python 2.7
