SysTyrant

This is an advanced declarative configuration management tool similar to puppet and chef.

This tool has some significant advantages over puppet and chef:

- Supports agent-less remote configuration (SSH-based), in addition to local and remote client/server based deployments.

- In addition to it's own DSL, it supports a very wide range of languages (java, ruby, javascript, and many others)

- Designed to build more than just servers, but whole environments.
