Q3.0.4: How can I add directories to the load-path?

Here are two ways to do that, one that puts your directories at the front of the load-path, the other at the end:

;;; Add things at the beginning of the load-path, do not add
;;; duplicate directories:
(pushnew "bar" load-path :test 'equal)

(pushnew "foo" load-path :test 'equal)

;;; Add things at the end, unconditionally
(setq load-path (nconc load-path '("foo" "bar")))

To add directories using Unix shell metacharacters use expand-file-name like this:

(push (expand-file-name "~keithh/.emacsdir") load-path)
