// bx_simulator_interface just defines the interface that the Bochs simulator
// and the gui will use to talk to each other. None of the methods of
// bx_simulator_interface are implemented; they are all virtual. The
// bx_real_sim_c class is a child of bx_simulator_interface_c, and it
// implements all the methods. The idea is that a gui needs to know only
// definition of bx_simulator_interface to talk to Bochs. The gui should
// not need to include bochs.h.
//
// I made this separation to ensure that all guis use the siminterface to do
// access bochs internals, instead of accessing things like
// bx_keyboard.s.internal_buffer[4] (or whatever) directly. -Bryce
