To use these generator templates I recommend adding this function to your bash profile.

function railsapp { template=$1 appname=$2 shift 2 rails $appname -m http://github.com/ryanb/rails-templates/raw/master/$template.rb $@ }

You can then use this "railsapp" command instead of the traditional "rails" one. Simply pass the template name as the first argument:

railsapp base store

That will generate a Rails app using the base.rb template found here.
