;;; Commentary:
;; of providing 5000 options, we'll stick to simple, easy to
;; understand options.
-;; Easy setup:
-;; (require 'auth-source)
-;; (customize-variable 'auth-sources) ;; optional
-
-;; now, whatever sources you've defined for password have to be available
-
-;; if you want encrypted sources, which is strongly recommended, do
-;; (require 'epa-file)
-;; (epa-file-mode)
-
-;; before you put some data in ~/.authinfo.gpg (the default place)
-
-;;; For url-auth authentication (HTTP/HTTPS), you need to use:
-
-;;; machine yourmachine.com:80 port http login testuser password testpass
-
-;;; This will match any realm and authentication method (basic or
-;;; digest). If you want finer controls, explore the url-auth source
-;;; code and variables.
+;; See the auth.info Info documentation for details.
