  # rainbow-delimiters

  `rainbow-delimiters` is a "rainbow parentheses"-like mode which highlights
  delimiters such as parentheses, brackets or braces according to their depth.
  Each successive level is highlighted in a different color. This makes it easy 
to
  spot matching delimiters, orient yourself in the code, and tell which 
statements
  are at a given depth.
