As is mentioned in Section 3.3, the user interface of Kheops is sophisticated and rather user unfriendly. That is why the gKheops project was started.
The gKheops system is a graphical user interface for Kheops. It communicates with the Kheops in real-time and gives user ability to control all aspects of Kheops without knowing the sophisticated Kheops's syntax.
The detailed description of gKheops can be found in [2].
