PySide API Extractor
The API Extractor was a library used by the binding generator component (Shiboken) to parse headers of a given library and merge this data with information provided by typesystem (XML) files, resulting in a representation of how the API should be exported to the chosen target language. The generation of source code for the bindings was performed by specific generators that were using the API Extractor library.
In PySide 1.1.1 [pypi.python.org] API Extractor was merged into Shiboken, but docs on it are still available.
The API Extractor is based on QtScriptGenerator [labs.trolltech.com] code.
