[emacs-wiki-discuss] a little help on reading elisp

[Rino Mardo]

now i know what "defun" does but the following i don't. maybe someone can help?

1. (defadvice planner-create-note-from-task (around joroxx activate)
2. "Stay in the same window."
3. (let ((planner-use-other-window nil))
4.    ad-do-it))

line 1 is supposed(?) to be "defun" but why is it "defadvice"?
line 2 is just a remark for this function
line 3 temporarily sets planner-use-other-window to nil or null
line 4 calls some function ad-do-it
