[Nitro] about Og development

[Antoniolo]

Hi ppl.

After making lots of superficial tests, I decided to move on with Og. 
Og is everything I need and even more than that ... but I still miss some
active-record features. Ok no problem, I'm adding them on my local gem and
proceeding with the development normally.

Today morning, I tried to run the latest Og version (from repo) but I didn't
get on well with it so far. I've seen the recent Og(from repo!) and it has
lots of code changes. I've also add some bug fixes and specially the missing
features and I'd really like to contribute.

The questions are:

- are you refactoring og's source code?
- Is there any clue which I need to know in order to run Og from repo?
- Is rspec being the default test framework?
- why darcs instead of svn?
