* Configuration
** Changing calendar sources
By defining your own calendar commands, you can control what sources to pull
calendar data from:

#+BEGIN_SRC emacs-lisp
(defun my-open-calendar ()
  (interactive)
  (cfw:open-calendar-buffer
   :contents-sources
   (list
    (cfw:org-create-source "Green")  ; orgmode source
    (cfw:howm-create-source "Blue")  ; howm source
    (cfw:cal-create-source "Orange") ; diary source
    (cfw:ical-create-source "Moon" "~/moon.ics" "Gray")  ; ICS source1
    (cfw:ical-create-source "gcal" "https://..../basic.ics" "IndianRed") ; google calendar ICS
   )))
#+END_SRC

To control what org files ~clfw:org-create-source~ will use, ~let~-bind
~org-agenda-files~ around a call to ~+calendar/open-calendar~ like so:

#+BEGIN_SRC emacs-lisp
;;;###autoload
(defun cfw:open-org-calendar-with-cal1 ()
  (interactive)
  (let ((org-agenda-files '("/path/to/org/" "/path/to/cal1.org")))
    (call-interactively #'+calendar/open-calendar)))

;;;###autoload
(defun cfw:open-org-calendar-with-cal2 ()
  (interactive)
  (let ((org-agenda-files '("/path/to/org/" "/path/to/cal2.org")))
    (call-interactively #'+calendar/open-calendar)))
#+END_SRC
