  ;;(add-hook 'text-mode-hook
  ;;  '(lambda () (refill-mode 1)))

  ;;Enable syntax highlighting when it's allowed
  ;;(when (fboundp 'global-font-lock-mode)
  ;;  (global-font-lock-mode t))

  ;;Fix the backspace key
  ;;(normal-erase-is-backspace-mode 1)

  ;;Use cperl-mode for editing Perl code, it is better than perl-mode
