What does (looking-at "\\>") mean?

[Wang Lei]

Hi, all.

I copied a piece of code like this:

(defun my-indent-or-complete ()
  (interactive)
  (if (looking-at "\\>")
      (hippie-expand nil)
    (indent-for-tab-command)))

But, I can't figure out what this "\\>" means. Could someone give me a
explanation ?

Many thanks!
