Hmm, we need to discuss plugins a bit more. I'm not sure they are
needed for either libtracecmd nor libtracefs. We have plugins for
libtraceevent which is just a better way to present the event, but I'm
imagining that plugins are going to be more specific to trace-cmd
directly. Maybe they can be packaged with libtracecmd, but I'm not
seeing a need for libtracefs.

What do you have in mind?
