RubyWorks production stack is a collection of open-source software required to host a RubyOnRails application on a Linux server, developed by ThoughtWorks Studios.
To set up a production Rails server, you point a package manager to RubyWorks package repository, run one command, and in a couple of minutes you have a skeleton Rails application served by a cluster of Mongrel servers, load-balanced by HAProxy, monitored by monit and controlled by runit.
...we should definitely make one of those "wow, how much I can get in
5 minutes" screencasts about this... 
Version 0.0.2 is a second development release of the stack, with the following useful and exciting new features:
* No need to compile anything on the production server (all necessary gems are available pre-compiled from RubyWorks gem repository); * The stack can be installed on Ubuntu 7 (Feisty Fawn) and Debian 4 (Etch) - although the latter requires libc from unstable APT repository (sid); * Database drivers with Ruby bindings for MySQL, Postgres and Oracle are provided; * all daemons are started and stopped by runit.
