Hooks are in libsvn_repos, so if you implemented a feature like this, it
would work for all access methods. Are these interpreters portable to all
of the operating systems that Subversion and APR support?
Finally, isn't there a stability advantage to running the scripts in a
separate process? Perhaps not.
