Rake provides make-like scripting capabilities directly in Ruby.

Rake 0.3.1 is major cleanup of the code base and offers the following new features:

* Expanded FileList capability with include/exclude semantics and auto-exclude patterns.
* Task Libraries to simplify common build tasks (e.g. packaging, testing, generating docs).
* Updated documentation.
* Rake can now be installed and run as a RubyGem.
