	namespace :deploy do
	namespace :assets do
	desc 'Run the precompile task locally and rsync with shared'
	task :precompile, :roles => :web, :except => { :no_release => true } do
	%x{bundle exec rake assets:precompile}

	This script performs efficient concatenation of files stored in S3. Given a
	folder, output location, and optional suffix, all files with the given suffix
	will be concatenated into one file stored in the output location.

	Concatenation is performed within S3 when possible, falling back to local
	operations when necessary.

	Run `python combineS3Files.py -h` for more info.
