That sounds as a possibility, indeed. I will experiment a bit.

They call it "shares". Yes it created confusion sometimes here too, but
team finally got used to them and we have to re-organize things a bit
now as part of our transition from VSS to SVN. ;-)

While we're at this, is there some way to setup something equivalent to
the concept of "shadow" found in Visual SourceSafe ? A shadow is a copy
of HEAD revision for a whole repository (or sub-projects of it) stored
in some external location and held incrementally up-to-date by the
versioning engine on each commit to the repository.

That is pretty much what you get by 'exporting', but it is handled,
server-side, at each ommit. All in all this what you can see through the
http view when using SubVersion with Apache. I suppose I could actually
mount the repository using a WebFolder to get that concept of an
up-to-date-after-each-commit global view on the repository. But is there
some other way of doing this ? Some scripting on the server-side acting
on each commit ?

I have read (quickly) the Book but obviously need to dive deeper.

Right, this is not what I was looking for.

Thanks Toby,
