There have been several modifications made in gKheops sources.
First of all the main function of gKheops have been modified to support command line arguments. Furthermore two functions have been added: osiris_launch_kheops and osiris_kheops_load_function. The second one allows the gKheops to load specified source-file without any interaction from the user. The first one is the main modification and allows to launch the Kheops and load the desired source-file.
All modifications are available as a diff file in the Osiris source code tree (see Appendix A.
