Yeah, he's extracting the Rails mechanism into a separate gem.

Along the same lines, but with a much simpler approach, I started to
work on Dependencies: http://github.com/djanowski/dependencies.

Given a simple ./dependencies file:

  rack ~> 1.0
  sinatra
  webrat (test) git://github.com/brynary/webrat.git

You get a correct $LOAD_PATH (then it's up to you to do the actual
require's) and simple commands to help you:

  $ dep list
  rack ~> 1.0
  sinatra

  $ dep list test
  rack ~> 1.0
  sinatra
  webrat (test)

  $ dep vendor webrat
  ...
  $ tree -L 2 vendor
  vendor/
  `-- webrat
      |-- History.txt
      |-- MIT-LICENSE.txt
      |-- README.rdoc
      |-- Rakefile
      |-- install.rb
      |-- lib
      |-- spec
      `-- vendor

Ok, you get the idea. As you'll see from the examples we're using this
on Sinatra projects and it's working great for us.
