GSC bit
GraphicServices Capability. A number of virtual packages made by Cydia on boot to make it easier to represent hardware and system software support for various features.
Mainly derived from the capabilities in the model definition file; a true boolean capability will create the package, while numeric capabilities will have its value stored as the package's version number.
