  # Pure - A minimal and beautiful theme for oh-my-zsh
  #
  # Based on the custom Zsh-prompt of the same name by Sindre Sorhus. A huge
  # thanks goes out to him for designing the fantastic Pure prompt in the first
  # place! I'd also like to thank Julien Nicoulaud for his "nicoulaj" theme from
  # which I've borrowed both some ideas and some actual code. You can find out
  # more about both of these fantastic two people here:
