Running specs faster with rails_spec

Loading the entire Rails environment every time a spec is executed is quite slow. We have therefore made a little tool
that allows you to load the rails environment once for all. In a separate shell, run:

script/rails_spec_server

[...]


Shouldn't this be script/rails_spec_runner

Fixed in 0.6.4. From the release notes:

Renamed rails_spec_runner to rails_spec_server (as referred to
in the docs)
