Some notes on various version control tools:
- Buildbot: http://buildbot.net/trac offers a way to build and test multiple repositories. Support mercurial
- Mercurial supports a forrest of repositories. You can have a repository that contains other repositories. That makes it easier to compose complex system. It’s not clear whether Forrest, Nested Repositories, or just being able to ignore a .hg directory is the route to go.
- Nice tutorial on using mercurial
- Linux and Windows diff tool
- Mac OS X diff tool
