I guess so--I might even say, "Duh", except I was the one who overlooked this :-).
In case anyone else is interested in using SFST from C++, I went back and looked at its README, which has this: ------ If you want to implement your own tools based on the SFST code, have a look at fst-infl.C and fst-infl2.C. They show how analysers are implemented with the standard (fst-infl) and the compact (fst-infl2) transducer format. ------ And the code there is quite simple :-).
