: As I tried to explain in reply to Roland, I'd like to handle the

: unison. Requiering them to be kept in the subtree is a good compromise
: which reflects what most users do anyway.
For deletion/archival, I think this is okay. For installation
(copying over from share/examples), I think it's not. So if all
``include files'' that get installed by the package must be listes as
(3), and (4) lists directories where the admin may place additional
``include files'', I'm happy with it.

I don't care about the details, just that we are able to handle
normally installed files that can change. So, that is fine with me.

True, user/gruop creation is special. Okay, let's keep them
