# rails_app/lib/tasks/asset_hat_extensions.rake
# AssetHat: http://mintdigital.github.com/asset_hat/
namespace :asset_hat_extensions do
namespace :css do
task :fix_media_queries do
# The `cssmin` gem has a bug in which it shortens
# `@media screen and (max-width:800px)` to

# This task re-adds the space.
