I think what Jostein means is - how would you know you need to take
all those steps?
I'm not 100% on what Semantic is doing for me.  I did run "make TAGS"
in the Emacs source directory, and it seems to do something, although
I don't know how much of that is Semantic versus one of the many other
packages I've loaded into the emacs dump I use.  I know I get great
completion sometimes, and I see  notifications that my Elisp buffers
get parsed by an LL parser.  The fontification is different, and the
header line is used for displaying the function scope point is in.
I added Yuan Fu to the CC per your earlier recommendation.  I'm not
sure what their role is - migrating the documentation?
