 +====== PrettyWoman ======
 +As part of this work, I looked at how to "standardise" our hooks, since they all appeared to be based on a couple of patterns. Below, you will find source and a CSV file for "PrettyWoman". This app name was picked by Jezzab because "PrettyWoman - She was a hooker".
 +
 +Anyway. Naming conventions aside. How does it work? There is a shell script that parses a CSV file that contains configuration information for a list of hooks that will be created in the output.
