[Orgmode] Exclude some file to be in the agenda

[Chao Lu]

Dear all,

The way I set the org agenda file is using all the *.org file in some dir. Like
(setq org-agenda-files (file-expand-wildcards "~/.emacs.d/org/org/*.org"))

But is it possible to exclude certain file to show up in the agenda? Sometime this will be handy.

Thanks,

Chao
