  5# Pure - A minimal and beautiful theme for oh-my-zsh
  6#
  7# Based on the custom Zsh-prompt of the same name by Sindre Sorhus. A huge
  8# thanks goes out to him for designing the fantastic Pure prompt in the first
  9# place! I'd also like to thank Julien Nicoulaud for his "nicoulaj" theme from
 10# which I've borrowed both some ideas and some actual code. You can find out
 11# more about both of these fantastic two people here:
