This gem provides the railtie that allows sequel to hook into rails3 and thus behave like a rails framework component. Just like activerecord does in rails, sequel-rails uses the railtie API to hook into rails. The two are actually hooked into rails almost identically.
The code for this gem was initially taken from the excellent dm-rails project.
Using sequel with rails3 requires a couple minor changes.
First, add the following to your Gemfile:
… be sure to run “bundle install” if needed!
Secondly, you'll need to require “sequel-rails/railtie” in your config/application.rb file, and not require activerecord. The top of your config/application.rb will probably look something like:
# require 'rails/all' # Instead of 'rails/all', require these: require "action_controller/railtie" require "sequel-rails/railtie" require "action_mailer/railtie"
After those changes, you should be good to go!

Once you do that, you will see the following rake tasks among others. These are the ones that sequel-rails added for us.

There are bound to be a lot, but I'm not yet sure what they are

The dm-rails team wrote most of this code, I just sequel-ized it.
Note on Patches/Pull Requests
Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
