Is it possible to use coffee file system (as a library) in my project
without the Contiki OS?

So, for an embedded project with external NOR flash and existing
commercial RTOS, can I use the coffee filesystem in a form of a library,
i.e. to compile it in? From what I've seen it seems possible, only the
dependencies go quite deep in to Contiki. I'll surely dig in, but may be
someone have done something of the kind already? Thanks.
