Overview

Works by maintaining a directory structure where each deploy creates a new directory. Each directory is given a timestamped name. Assets are symlinked into a special ‘current’ directory from each of the timestamped directories. Each invocation overrides existing symlinks if they already exist. This technique ensures assets from the previous deploy remain available while the web servers are restarting.
