My version of the railsComposer.sh script

rails_composer

#!/bin/bash

project_name=$1

if [ -z project_name ]; then
  echo
  echo "projects need names too, I'm sure you can think of a neat one!"
  echo "  ex: rails_composer neat_name"
  echo
else
  mkdir $project_name
  cd $project_name
  rails new . -m https://raw.github.com/RailsApps/rails-composer/master/composer.rb
