To use these generator copy this in your .bash_profile
function railsapp {
appname=$1
shift 2
rails new $appname -m https://github.com/brunow/rails-templates/raw/master/app.rb -TJ $@
}
So you can use this command in your shell instead of rails new
railsapp app_name
Bash function from https://github.com/ryanb/rails-templates/
