Indeed. I tried that with bison->wisent, but found the translation left
out a lot, and I just ended up getting confused.

In this case, "Emacs program" means something written in Emacs Lisp that
will convert the output of some external program into something
Emacs/CEDET/Semantic can use. This would be similar to the exuberant
ctags support that is part of Semantic.

If I made it sound hard, no one would try. :)
Besides, the exuberant ctags example already in Semantic can likely be
used to prototype in new programs.
