I have been looking at the examples provided with the cffi material, as well as at
the manual, to see how the wrapping of c functions seems to work. These are very helpful
but depend on system calls and "eveything" knows where they are.

Suppose I have a set of c functions, and their .o files too, which I would like to
wrap using defcfun and relatives.

What precautions must I take in making known to ccl the locations(s) of these
foreign files ? Is it a bit like asdf with a *central-registry* to hold such locations,
or have I missed some obvious pointer to the answer ?

Thanks for any and all assistance.
