Audit this entire codebase for materially useful simplifications in its data structures, state representation, control flow, algorithms, and ownership.

This is an audit-only exercise. Do not edit files, run tests, implement recommendations, commit, or push. Read-only inspection commands are allowed.

You are the coordinator. Continue until the complete codebase has been reviewed and the final audit is validated.

1. Establish the coverage contract

Inspect the repository and inventory every identifiable subsystem.

These instructions install ruby and rubygems from source, not from RPMs. For instructions on installing from RPMs, look at something like http://wiki.opscode.com/display/chef/Installation+on+RHEL+and+CentOS+5+with+RPMs or http://mykestubbs.com/blog/2010/03/chef-installation-on-centos-54.html
