SQBind is a pretty simple, yet powerful binding library for the Squirrel language. It includes support for binding classes, methods, static methods, member variables, functions, enums, and C types. It can either manage pointers or leave them unmanaged. It also recognizes functions that receive pointers or references and passes values accordingly. It also easily lets you use your own types for taking care of native Squirrel types, such as your own (or std::) string class, table class, array class, etc.
PySide provides a full set of Qt bindings and automated binding generation tools. The binding generation tools can be useful for creators of Python bindings to any Qt-based library or to any C++ library in general. Although based on a different technical approach, PySide will initially be API-compatible with existing Python bindings for Qt.
