Installing plugins from GitHub

ruby script/plugin install git://github.com/thoughtbot/paperclip.git

Somehow I couldn't get this to work with active_scaffold (which I don't use now, anyway). It tells me

Plugin not found: ["git://github.com/activescaffold/active_scaffold.git"]

I have gitbash installed on my Windows so I was finally able to do this.

cd vendor/plugins
git clone git://github.com/activescaffold/active_scaffold.git -o rails-2.3
