bundle_mongo_template.rb

# bundle_mongo_template.rb
# 
# fork of Ben Scofield's Rails MongoMapper Template (http://gist.github.com/181842)
#
# This template:
# - Adds Bundler support
# - Adds MongoDB support
# - Removes default files and javascript
# - Installs common gems via bundler: mocha, shoulda, factory-girl, shoulda_generator, haml, mongrel
#
# Facts:
# - Tested with Rails 2.3.8, but should work with any 2.3.x
# - Uses git
#
# To use:
# - rails project_name -m http://gist.github.com/419566.txt
# - Don't forget to start the mongodb server
#
