Is there a Mercurial equivalent to gitosis?

I've used ( and still use ) mercurial and git. I have some repos hosted in a server with gitosis which is great and easy to setup. I am looking for a similar tool for开发者_如何学JAVA hosting mercurial repos.

It must provide minimal acl and ssh access and allow for remote config ( in the style of gitosis's "clone the admin repo and push changes" ).

Extra points for automating hgweb config via said tool.

This article describes how to set up the gitosis-like mercurial-server for Mercurial.
