setting bugtraq propertiers automatically

Hi all!

We have various projects in our repo. Some just consist of a trunk,
branches and tags folder, others have a somewhat deeper structure.
We use the bugtraq properties to display a ticket field in tsvn.

The easy-structured projects do not have any problem with this, because
once set, the properties are usable.
But there are projects, that grow contiously. Unfortunately those who
work on these projects, do not checkout pre-defined paths (e.g. only the
trunk), but check out at "random" as necessary. So each folder of those
projects needs to have the bugtraq properties.

What can I do in order to release those people from having to add 6
properties manually each time they create a folder?

If I am correct, auto-props do not work on folders at the moment.
Adding the properties via a hook-script is no option due to the known
reasons. There are no client-side hooks, yet, are there?
And one cannot checkout the whole root and apply the settings
recursively because that would affect tags, which is not allowed due to
our pre-commit-hook.

Any ideas?

Thanks!

bye,

Nico
