Register programs

As it is time to change versions
and I'm using cl-http with many small "programs"
and this damn cl-http does not crash :-),
I often forget some things when starting all new, because there are
some months gone, since I did it last time.

So I'm looking for an automatic mechanism for the "programs"

-to  register (load  or load/dump)
(-to  unregister (remove))
-to get called by the enable/disable-http-service
 for local start/stop handling (e.g. clear cache to db).

do such "hooks" exist, is there a standard way to do this,
or how do you handle these problems?
