As far as I understand xenvm/xenops (toolstack.git/xenvm/*.ml) are only 
frontends to the xenops library files (toolstack.git/xenops/*.ml) which 
in turn are helper functions for libxc calls. Is that correct? And if 
so, could I simply use libxc's functions for doing simple tasks in XCI 
(using C as programming language)?
