Getting the timelog example to work:

This was tested in ruby 1.9.3.

Get the code
  git clone https://github.com/kevinrutherford/rrwb-code
  cd rrwb-code/timelog

Set up some required files and settings
  mkdir data
  touch data/timelog.txt
  export TL_DIR=<whatever your full pathname prefix is>/rrwb-code/timelog/data

Run program with
  ruby timelog.rb  project1

Edit timelog_test.rb
  Change throughout:
    ruby timelog/timelog.rb 
        to 
    ruby timelog.rb
  Change once:
    load 'timelog.rb' 
        to 
    require_relative 'timelog'

Run tests with 
  ruby timelog_test.rb

If you want to run the Cucumber tests, too:

  gem install cucumber --no-rdoc --no-ri
  gem install rspec-expectations --no-rdoc --no-ri
      or
  sudo gem install cucumber --no-rdoc --no-ri
  sudo gem install rspec-expectations --no-rdoc --no-ri
      or
  Use bundler and Gemfile to add the two gems

  Edit features/support/env.rb
    Change 
      require 'spec/expectations' 
            to 
      require 'rspec-expectations'

  From timelog dir, run tests with 
    cucumber features/timelog.feature
