The main reason is to make bisect easier. In some points, we have a lot of git dependencies. Since we don't have the information of which commit we are referring to, bundler get the latest commit of the master branch of the dependency. This sometimes returns a version that is not compatible with Rails anymore, making the tests fail and the harder to identify the commit that introduced a bug. Also this will make sure that a contributor will always get a set of dependencies that are passing with our tests. In our CI server we delete the lock file to make sure we are always testing against the newest release of our dependencies.

RDoc autolinks the word "Rails" to the doc page for the Rails module. But README.rdoc is displayed in the home page at GitHub and the slashes are visible there, which is weird. We leave by now the slashes off in the file, and generate a second file for the API with them.
