work with fogbugz. Very useful for code review

Easily setup and manage Mercurial based-code repositories. Easy to setup mercurial clients (TortoiseHg) to push and pull to Kiln. Web-based file and changeset diff-views allow code to be quickly browsed and reviewed. Built in web-hooks for Fogbugz and Pivotal Tracker (we use both of these for issue/bug tracking) allow commit messages to auto-post to project management systems. Although we don't utilize it fully, the Code Review system provides an easy way for developers to comment on commits and changesets.

The deployment tools were best of breed when they first arrived, and they continue to have a very solid offering especially with providing support to AWS services.
