Collections of tools I use to work, and a script to install them on a machine
In order to stay up to date with the (many) plugins I have installed in my dotfiles, I make use of git submodules. In order to update all of the submodules, type
$ git submodule foreach git pull origin master
This will pull from every repository, maintaining them up to date.
In order to add a submodule, then type
$ git submodule add git://github.com/chneukirchen/rack.git rack
