No, I am not.  The hook I'm asking for is _not_ the same as the various
other revlib-related hooks that have been proposed by other people.

I'm asking for a hook-script which _returns the path to search for the
revision library_.  The hook script will use any state it wants from the
current project tree to help it search; crucially (for my purposes), it
can use state _other_ than just the project tree's archive.

[Another case of course is when you're doing an initial get, and so
aren't in a project tree; in this case, the script again can use any
state it needs to.

That's what I'm trying to do too.

And I'm saying that's neither sufficient, nor usually necessary (the
main point of the latter being that it's annoying if you have to
actually specify it for many archives).

That's what I want to do too.

That's why I want a hook-script.

Sure; so read my post again to see my position on the storage.
