It's a bit more problematic since they might be scripts or data files; I
also need to store config files. But you are right, the current scheme is
not the best. It's very hard to find where to put these kind of mixed
stuff. The current scheme is that the exteral HID looks for pcb-gpmi.conf
on all the paths the HID's so could be and load the modules listed in that
file. If the module is a script module, it's param is a script name.
