How to setup Compass Twitter Bootstrap

compass.rb

# This configuration file works with both the Compass command line tool and within Rails.
# Require any additional compass plugins here.
require 'compass/util'
require 'compass/browser_support'
require 'compass/sass_extensions'
require 'compass/version'
require 'compass/errors'
require 'compass_twitter_bootstrap'

project_type = :rails
project_path = Compass::AppIntegration::Rails.root

# Set this to the root of your project when deployed:
http_path = "/"
# You can select your preferred output style here (can be overridden via the command line):
# output_style = :expanded or :nested or :compact or :compressed
# To enable relative paths to assets via compass helper functions. Uncomment:
# relative_assets = true

# If you prefer the indented syntax, you might want to regenerate this
# project again passing --syntax sass, or you can uncomment this:
# preferred_syntax = :sass
# and then run:
# sass-convert -R --from scss --to sass app/stylesheets scss && rm -rf sass && mv scss sass

environment = :production
line_comments = false
output_style = :compressed
