Paper Trail is a single-user publishing tool for book reviews. It's written in Ruby on Rails; content should be formatted using Markdown. Paper Trail is written by Benedict Eastaugh and licensed under the GPL.

Like all Rails applications, Paper Trail needs a database.yml file with the relevant configuration details to be added to the config directory. In addition to this, an environment-specific configuration file named papertrail.yml can be added to the config directory to add some simple customisations to the application. Here's a sample configuration block for a development environment.
