FFI-based GObject binding using the GObject Introspection Repository

 GObject is an abstraction layer that allows programming
 with an object paradigm that is compatible with many

 This package contains the dynamic Ruby binding generator

 which ship a gir1.2-<name>-<version> package. With these
 packages, the libraries can be used from Ruby.
