# ref/ is NOT part of a klammer set: it is the reflection library, whose
# C++ reads the engine's OWN registries and character tables and returns
# Klammertext.  It is built here because, like the sks DSOs, it links
# against libklammertext.so -- but it is a separate target so it does not
# become "part of sks" by association, which is exactly the confusion the
# klammer-set naming is trying to undo.
