Depend from the sense you give to the word "hybrid". The prolog script do
not handle resources and configuration. It only create symlinks in the root
filesystem located where usually a program like to find them.

Example: this is a row extracted from the perl's prolog :

                # ln -s -f /usr/perl/CPAN /usr/lib/perl5

because perl5 like to have a directory called /usr/lib/perl5/CPAN, not
/usr/perl/CPAN.

To put the add-ons specific .fun on the add-on disk is not so straightforward
as one can think. Let me give some example: the httpd.fun, the sendmail.fun
and other. They can work WITH and WITHOUT the SRV addon, acting
differently in both cases. httpd.fun starts thttpd if available; otherwise
it starts pygmy.
