SUMMARY = "Middleware layer between GObject-using C libraries and language bindings" DESCRIPTION = "GObject Introspection is a project for providing machine \ readable introspection data of the API of C libraries. This introspection \ data can be used in several different use cases, for example automatic code \ generation for bindings, API verification and documentation generation."
