Access control to parts of the repository

[Mike Bernson]

What I am looking for is a way to control who has access access to parts of repository
I known SVN can do this but I see no way for hg to control access to subdirectory in the repository.


I would like to allow some user write access to part of the repository so that
the group working on some subdirectory has control of change. It would also be nice
to have read access control. I would like to put code into the repository under a
subdirectory and not allow people to see it until it is ready form them but allow
the user write the new code to have a place to share it.


Is there an access control handle this kind of thing ?
